This article is comprised of a complete list of all the homebrew Space Marine Chapters created by our contributors here on the WH40K Homebrew Wiki. Along with a brief synopsis of each chapter, this list also serves as a visual reference. Included in this list are Expanded Universe and Alternate Universe Chapters as well as those Space Marine Chapters that have been declared Excommunicate Traitoris by the High Lords of Terra, regardless if they serve the Dark Gods or not.

This list does not include Space Marine Chapters that fall into the humour category. This list also does not include Blackshield forces or units as they are technically not full Space Marine Chapters, therefore, they fall into their own Blackshield category.

This is an ongoing project, and as such, additional Chapters will be added or removed accordingly. For those Chapters that are missing from the list, please feel free to edit this article and add it, or if the Chapter article has been deleted, feel free to remove it.

Name	Image	Notes
Aacharns		The Aacharns are a Codex-compliant Loyalist Space Marine Chapter of the Adeptus Astartes from the 25^th Founding, the so-called 'Bastion Founding', of unknown genetic lineage. The Chapter is unique in that while it is strongly compliant to the Codex Astartes, it also rigorously follows a unique splinter sect of the Imperial Cult in which they believe that the Emperor' ascended to divinity upon sitting on the Golden Throne and that His soldiers must honor Him by defeating His foes in a ritual hunt and marking them as claimed in his honor, via scrimshaw.
Aardwolves		The Aardwolves are a fleet-based, loyalist non-Codex compliant Space Marine Successor Chapter created from an unstated lineage and comprised entirely of newly revealed Primaris Space Marines. The Chapter keeps to themselves, preferring to wage their own war against the enemies of Mankind. They choose to never fight alongside other forces of the Imperium or join a battle on the orders of others than themselves.
Aasvogels		The Aasvogels, an Ultramarine Successor Chapter, were originally raised during an unknown founding in the early M37, and refounded again during the 26^th Founding, in response to the growing threat posed by Chimeric Chapters within the Imperium following the 21^st 'Cursed' Founding. A Codex Astartes-Compliant chapter with a covert mandate to hunt down and eliminate Chimeric Astartes, the Aasvogels have become one of the most dangerous Chapters among other Astartes. Their ability to track and eliminate targets has rendered them an invaluable resource for Imperial forces combating these mutated warriors. Derived from Ultramarines' gene-seed, the Aasvogels possess not only a strong sense of duty and tactical acumen but also unique traits that enable them to operate adeptly in shadows, tracing targets without detection. The Aasvogels maintain strong connections with various branches of the Inquisition, particularly the Ordo Astartes, forging a formidable partnership in their crusade against heresy and abominations within the Imperium. Through their collaboration, they share vital intelligence, resources, and a shared zeal to safeguard humanity from encroaching darkness. With immense pride, the Aasvogels consider themselves the Imperium's guardians against the abominations of the Chimeric Astartes. Scant available information about the Aasvogels hints at its foundation as a response to the rise of corrupt chimeric chapters, with a primary mission to track down and eradicate these abominations. The chapter's ties with the Inquisitorial Ordos have sparked rumours suggesting it might have been established upon the request of the Inquisitorial Representative on Terra.
Abators Golden		The Abators Golden, also called the Philosophers (sometimes pejoratively), are a Loyalist semi Codex-compliant chapter of Adeptus Astartes of unknown founding and of officially unknown origin, although most believe them to be descended from the Imperial Fists. Based in the Segmentum Pacificus on the world of Sapientia, the chapter specialises in dealing with world pacification- planetary conquest, suppressing rebellion drop pod assaults, and cleansing of heresy, as well as reconstructing worlds and establishing schools and temples following the fighting to prevent future rebellion, leaving worlds far better than they arrived and extremely unlikely to rebel again. They are also known for being strategic, decisive, and relentless in action, yet careful and methodical after the fighting has ceased in order to bring people into the Emperor's light. This desire to teach and to better results in the Astartes being uniquely open with the humans they encounter, provided they are not enemies of truth. The chapter has many unique characteristics which distinguish it from other chapters. It is a deeply religious chapter, taking seriously the worship of the Emperor and having strong religious rites and ceremonies. Even distinct from other religious chapters, however, it is well known for its simultaneous emphasis on both faith and reason and the personal pursuit of philosophy and truth as being keystones to understanding the order and goodness of the universe.
Abbots of Absolution		The Abbots of Absolution are a proud yet secretive Chapter of Space Marines whose origins are lost to time, perhaps only known to the inner circle members of the order themselves. Masters of terror tactics and obsessed with purifying the uncleansed, the Abbots are some of the most ferocious warriors to roam the galaxy to this day, and the mere mention of their name evokes fear and desperation in xenos and dark servants alike. Even though these battle-brothers have untold victories in the defense of mankind, a terrible secret in their own threatens to destroy their entire history, and there are those that would be glad for such horrifying fate to come soon upon the marines.
Abyss Gazers		The Abyss Gazers are one of the Chapters created during the ill-fated 21^st Founding, the so-called 'Cursed Founding'. The Abyss Gazers were founded to police the edges of the Eye of Terror and have only just managed to survive due to both bad luck, mutation, and a section of the chapter breaking away and turning to Chaos. After nearly twice being declared Excommunicate Tratoris, the chapter is now somewhat closely monitored by the Inquisition, much to their ire.
Abyss Stalkers		The Abyss Stalkers are a non-Codex compliant Space Marine Chapter in the 41st Millennium, created as a part of the Ultima Founding of Adeptus Astartes from the lineage of the feral Space Wolves. The Abyss Stalkers are masters of terror combat, attacking bit by bit, leaving destroyed corpses and hanging bodies on poles, slowly destroying enemy moral before releasing an all-out assault. Though they are a loyal Chapter, they are known to be more aggressive than most of their fellow chapters; attacking those they deem as heretics on sight, claiming it as an act of the Emperor's Executioners. It is unknown if this is one of the side effects of the Canis Helix.
Abyssal Rukhs		The Abyssal Rukhs are a strange chapter bound in shadowed methods and shadowed intent, hailing from the world of Masyaf the shadowy assassin-marines that stalk the vast shifting sands of that world are an unnerving ally for those not prepared for the forces of the Shade Raptor. Surprisingly, there is sparse accounts recorded in official Imperial historical records, however, those few extant records that do exist, indicates that this mysterious Chapter was once known as the Hell Rocs - created from the lineage of the shadowy Raven Guard during the ill-fated 21^st Founding - the so-called 'Cursed Founding'.
Accentors		The Accentors are a loyalist Codex-compliant Space Marine Successor Chapter created from the lineage of the legendary and feared Raven Guard during the 25^th Founding, also called the 'Bastion Founding', in late M40. They generally follow the Codex Astartes, though there are some differences due to their limited numbers and their preferred means of tactics and deployment of forces.
Accipiters		The Accipiters are a valiant Codex-compliant Successor Chapter created during the notable 23^rd 'Sentinel' Founding from the lineage of the Corvus Corax. This Chapter is known for its exploits against the xenos horros and Chaos strongholds of the Segmentum Tempestus. This millennia-long crusade awarded the Accipiters with many accolades. It culminated in the Chapter receiving the feral world of Henst as a recruitment world in early M41 for their efforts, in addition to their official homeworld of Sedonus. While the Accipiters abide by the edicts of the Codex Astartes, penned by Roboute Guilliman, the Chapter has a particular love for using ranged weaponry and luring an enemy to a deadly ambush with Assault Marines. (Note: This Chapter falls under the Expanded Universe category.)
Adamant Wardens		The Adamant Wardens are a non-Codex compliant Space Marine Chapter in the 41st Millenium. They were created as a part of the 22^nd Founding of Adeptus Astartes from uncertain lineage. The Adamant Warriors are siege masters, specialising in the breaking of sieges and assaults on static fortifications. Though a loyal Chapter, they have a reputation as being quite dour and secretive, much to the dismay of other Imperial organisations such as the Inquisition.
Adamantine Knights		The Adamantine Knights are a Loyalist Chapter of the Adeptus Astartes descended from the honoured Dark Angels and their Primarch Lion El'Johnson through the Angels of Absolution. They were founded during the 23^rd "Sentinel" Founding, to replace a chapter of the Astartes Praeses that had been destroyed by the Forces of Chaos. They made their home on the feudal world of Lazaron, a planet culturally and geographically identical to the Dark Angels' long-lost home world of Caliban.
Alpha Red Guardians		The Alpha Red Guardians are a Loyalist Space Marine Chapter of the Adeptus Astartes of the Imperium. Formed in the latter years of the Indomitus Crusade as a recent addition to the Chapters of the Adeptus Astartes, the Alpha Red Guardians has yet to establish itself as a respectable chapter. This is mostly due to the chapter they were formed from. Unlike most chapters, the Alpha Red Guardians are comprised entirely of Primaris Space Marines who have a disliking by the older generation of Astartes.
Anacondas		The Anacondas Space Marine Chapter are a loyalist non-Codex compliant Successor Chapter that was created from the lineage of the feared Raven Guard. The Chapter was founded during an unstated Founding in mid-M38 to face the threat against the Imperium during The Waning, which lasted from early in M38 until ca. 744.M41. During this period the Imperium faced numerous threats that slowly led to a degradation of the Imperium's stability, power and peace by both Chaos and xenos that assaulted Imperial space. This long conflict shaped the Chapter into what it is today and their reputation as invisible, deadly and terrifying has since continued to grow.
Angels Celestial		The Angels Celestial are Loyalist, non-Codex complaint Space Marine Chapter of the venerable Second Founding, owing their descent from the mighty Blood Angels, comprised solely of Primaris Space Marines as of the present. Favouring fast assault and martial superiority to gun lines and mechanized advances, the Angels fly into war mainly in Mk X Jump-packs, brandishing chain- and power swords and engaging the foe in honourable melee combat. Over their nine thousand years of history, the Angels Celestial have served the Imperium with honour and valour. The entire time, the Angels fought against their genetic flaws inherited by the Blood Angels with as much determination as they do to the enemies of the Imperium, and they have been able to control the Red Thirst to an extent, but with no avail concerning the Black Rage.
Angels Imperatus		The Angels Imperatus are a Loyalist Successor Chapter belonging to the Dark Angels. Created in the 21^st 'Cursed' Founding of M35, they settled on the planet of Nag'rak. Nag'rak was seated to the west of the Nether Coil, a warp storm sitting on the west of where the Great Rift would eventually be. The Angels Imperatus aren't associated with the Inquisition or Adeptus Arbites, rejecting assistance and reinforcements from the Sisters of Battle, Adeptus Custodes, Astra Millitarum and Sisters of Silence. They perceive the hunt for their heretical brethren as their own burden, not anyone else's. Because of this goal, they very loosely follow the Codex Astartes.
Angel's Litany		Angel's Litany are a Loyalist semi Codex-compliant Successor Chapter created from the proud Sons of Sanguinius during the 4^th Founding, shortly after the infamous War of the Beast. Angel's Litany is created following the liberation of Ragrin System from the Forces of Chaos led by House Moghal, and the Chaos Cult known as the Blooded Fist of Maurha. The Chapter exclusively recruits its members from the Hive World Kandyra and the surrounding planets of Ragrin System. The Chapter is known for its usage of Azkaellon Pattern Bolts, a Bolt filled with an intense, energetic beam of heat in the tens of thousands of degrees Centigrade as well as the unusually large quantity of Sanguinary Guard armed with Power Glaives and Power Axes.
Angels Mortis		The Angels Mortis are a devoutly religious 23^rd 'Sentinel' Founding chapter who claim the lineage of the First Legion and the bloodline of the holy Primaris Angelus Mortis. The chapter has its own unique view of the Imperial Creed leading them to view the Lion as the first Imperial saint and the Emperor's Angel of Death who will guide them to the Emperor's side. For most of their history the chapter focused on the gathering of holy artefacts linked to the Primaris Angelus Mortis and bringing the word of the God-Emperor to all across the galaxy, whilst mercilessly purging those who refused it. However, their legacy of dedicated and stalwart service has been tarnished by accusing their fellow Unforgiven chapters, the Silver Lions and Ebon Angels, of heresy and collaborating with the Fallen leading to the War of the False Traitor. The Angels Mortis would be defeated in this war and for their ignorance were excommunicated from the Unforgiven and left as a broken chapter. The Angels now seek to repent for their past sins and seek to regain their former grace amongst their fellow Unforgiven.
Angels Nemesis		The Angels Nemesis are a Loyalist Successor Chapter created from the proud and heroic lineage of the Blood Angels following the disastrous events of the Devastation of Baal at the hands of Great Devouer. This Chapter was created during the most recent Ultima Founding and is comprised mostly of newly revealed Primaris Space Marines. The Chapter's command cadre is made up of surviving veteran Firstborn from various remnants of now-extinct Blood Angels Successor Chapters that were wiped out during this lamentable campaign. This Chapter has been charged by Lord Commander Dante, the newly-appointed Regent of Baal, to seek out and destroy the Tyranid menace whenever it is encountered.
Angels Repentant	Pict-File Unavailable	The Angels Repentant are an Ultima Founding chapter of the Adeptus Astartes, formed by Commander Dante following the Devastation of Baal, where the veterans of the chapter served under the colors of the Blood Angels. They operate on the fringe of the Imperium Nihilus, currently stationed in the Urhus System. Known for tactical prowess, Astartes of the Angels Repentant prefer laying bolter fire at a distance, before closing the gap to rip their enemies to shreds. After the battle, these battle-brothers are known to exercise their rage through the creation of art, and as such, the chapter's fortress-monastery is known to be lined with breathtaking paintings, sculptures, and many other masterpieces.
Angels Vampiric	Pict-File Unavailable	The Angels Vampiric are a non-Codex compliant, fleet-based Successor Chapter of the heroic Blood Angels Space Marine Chapter. Founded around M34 as the result of a failed secretive experiment. The experiment in question was meant to cure the Blood Angels of the dreaded 'Twin-Flaws' known as the Red Thirst and the Black Rage, however, it went horribly wrong and instead amplified these genetic flaws. After the experiment was declared a failure, it was decided that instead of purging the subjects of the experiment, a new chapter would be created from the surviving test-subjects. The highest ranking of these test subjects, a sergeant by the name of Count Orlok took up the position of chapter master of the new chapter. The Angels Vampiric are loyal to the God-Emperor of Mankind, however, they have been known to worship their Primarch Sanguinius more so than they worship the Emperor. They hold the belief that eventually, Sanguinius will return and restore the Emperor to his original power, and together the two of them will lead the Imperium to greatness once again.
Angels of Anguish		The Angels of Anguish is a semi-Codex Astartes-compliant Loyalist Successor Chapter created from the gene-seed of the ancient and heroic Blood Angels Chapter during the 2^nd Founding. Created as they were from the Blood Angels' gene-seed, the Angels of Anguish also carry the genetic Flaw inherited from their gene-sire Sanguinius. In addition to the twin flaws, the Angels of Anguish also have a third genetic flaw: deafness. The thrice damned Angels of Anguish, a most peculiar Chapter of the Blood, stand apart from their fellow Successors due to their unique devotion and practice of martial arts. They are renowned for their exceptional skill in unarmed combat, and the Chapter has a strong culture of competition when it comes to dueling and hand-to-hand fighting.
Angels of Damnation		The Angels of Damnation are a Codex-compliant chapter. Founded during an unknown but nonetheless ancient founding, this Chapter hails from the secretive Dark Angels. Claiming to be Avengers of the Lion, they act as judge, jury, and executioner of the Damned - the Forces of Chaos and Fallen Astartes Chapters. Successors of the ancient and mysterious Firewing Protocol, they have grown to become brutal and pragmatic in battle. Carrying out "Damnation Crusades", the Chapter is known to make targeted assaults on enemy strongholds and weak points, and the chapter has become proficient in Anti-Astartes Actions. (Note: This Chapter falls under the Expanded Universe category.)
Angels of Rebirth		The Angels of Rebirth are a Loyalist Successor Chapter created from the genetic lineage of Sanguinius during the 7^th Founding. They are something of an unusual chapter, even amongst the Successors of the Blood Angels. They have borrowed many ideas from the Raven Guard including their tactics, chapter beliefs and mannerisms. Despite their close ties to both the Blood Angels and the Raven Guard they tend to distance themselves from other Blood Angels Successors with the exception of the Lamenters. They feel a close kinship with this fellow Chapter of the Blood due to their similarity at having deviated from the original vision of the Emperor and Sanguinius.
Angels of Repentance		The Angels of Repentance are a Codex Astartes-compliant Loyalist Space Marine Chapter whom claims to have been created during the 2^nd Founding from the lineage of the ancient Dark Angels. Although their lineage is disputed, they hold many similarities with their proclaimed Progenitor Chapter. Officially founded on the world of Caanan in Segmentum Tempestus, they quickly became a fleet-based chapter. The Angels of Repentance are known to be extraordinarily secretive, even when compared to their fellow brothers in the Unforgiven. Although they claim lineage from the Dark Angels, many records related to their founding are missing, and any Imperial records pertaining to this have either been lost or destroyed. Because of this, many Unforgiven chapters do not actually see the Angels of Repentance as amongst their numbers, although the Dark Angels have not weighed in on the matter. (Note: This Chapter falls under the Expanded Universe category.)
Angels of Salvation		The Angels of Salvation or Angeli na Spaseni in High Gothic, are a loyal 4^th Founding Chapter of the Adeptus Astartes. Founded by legendary veterans of the Dark Angels. This Chapter shares many things with the honored first sons of the Emperor, including their highly stable gene-seed. In the years following their founding they fought hard to break free of the progenitor's shadow and forge their own legacy. They brought salvation to many a besieged imperial worlds and freed trillions from the oppression of deranged planetary governor's attempts to leave the Imperium. They are uncharacteristically forgiving for a member of the Unforgiven, believing that they should not bear the sins of their forebears, and that their own actions and legends will bring them salvation. Evacuating populaces when necessary along with aiding in reconstruction is common practice when situations and time permit.
Angels of Silence		The stoic and silent Angels of Silence are a semi-Codex Astartes-compliant chapter hailing from the noble heritage of the secretive Dark Angels. Known for taking vows of silence once they become fully-fledged Battle-Brothers, the Angels of Silence fight with no word nor noise coming out of their mouths. Known to their enemies as soulless killers on the battlefield, avenging angels of darkness, they invoke fear into the hearts of their enemies and allies alike. the Angels of Silence are known, unlike the date of their founding, to be successors to the ancient and brutal Dreadwing Protocol of the I Legion - Dark Angels.
Angels of Slaughter		The Angels of Slaughter are a bloodthirsty loyal, semi-Codex-compliant chapter. The reason why they are violent is because they believe it is the Emperor's will to decimate the foes of the Imperium, gaining themselves an infamous reputation with many Imperial Forces. Many of their loyalist brethren refuse to fight alongside them or even speak to them because of the Angels of Slaughter's brutal and violent tactics. Though it may be a shame to many, most of the Angels of Slaughter's allies are as bloody and brutal as themselves. Much of the chapter's founding records are purged or censored for unknown reasons but they are recognised as a successor chapter of the Blood Angels. A heroic and well-known chapter and the IX^th Legion of the Legiones Astartes. Unfortunately, they have also been known to be successors of the World Eaters Legion, a psychopathic and bellicose Traitor Legion led by the mad berserker of a Daemon Prince Primarch; Angron Thal'Kyr. The Angels of Slaughter deny claims of this heretical accusation but it could as well be the truth. This led to the difficult relations with the Inquisition.
Angels of Twilight		The Angels of Twilight is a loyalist Space Marine Chapter created during the 4^th Founding from the lineage of the ancient and aloof Dark Angels. This Chapter is known for rapidly deploying Fire Support Squads deep into enemy lines with Drop Pod assaults; delivering the maximum amount of damage to key enemy personnel and structures as quickly as possible. Like most Chapters of the Unforgiven, the Angels of Twilight are a fleet-based chapter ever on the hunt and tend to steer clear of others - focusing on their own shadowed agendas.
Angels of Ulan		The Angels of Ulan are a Loyalist Space Marine Chapter created as one of twenty separate Marine Chapters that have been sworn to defend the Pios System from encroaching xenos raiders, the Forces of Chaos and whatever else that lay beyond the known reaches of Imperial space. This Chapter was created during an Unknown Founding from the lineage of the Great Angel Sanguinius sometime in M32. Most unusual for a Chapter of the Blood Angels is that the Angels of Ulan are seemingly less affected by the dual-genetic curse of the terrible psychosis known as the Black Rage or the insatiable bloodlust of the Red Thirst. How the Chapter managed to achieve this seemingly impossible miracle, or by what dark bargain they struck to buy their salvation, is unknown to outsiders. However, it remains to be seen whether or not this will be the Chapter's their undoing.
Angels of the Blade		The Angels of the Blade are a 4^th Founding Loyalist Successor Chapter that descends from the lineage of the mysterious Dark Angels, and as such, are members of the collective of fellow Scions of the Lion Chapters known as the Unforgiven, with an Inner Circle that constantly hunt for the Fallen.
Angels of the Cruciform Grail		The Angels of the Cruciform Grail is a Loyalist Codex-compliant Successor Chapter, born of the 2^nd Founding from the heroic Blood Angels. These blessed sons of Sanguineous protect the Grail of Sanguinius - the chalice containing the blood of their dead primarch. The blood is drunk by each chapter master during their induction to grant them everlasting life. The grail is kept deep within their fortress-monastery of Alexandretta.
Angels of the Lion		The Angels of the Lion are a Loyalist Successor Chapter of the venerable Dark Angels, created during 7^th Founding just before the occurrence of the event known as 'The Howling'. Much of their history is shrouded in mystery, known only to these Astartes themselves. The Chapter takes pride in their collection of relics and their allegiance to the Imperium. On top of this pride in their relics, the Angels of the Lion is always looking for more information to the structure of the old I Legion. Somewhat due to this heavily traditional nature, the Angels are incredibly hesitant to accept Primaris Space Marines into their ranks, however, they have since worked out their differences with their new brethren.
Angels Palatine		The Angels Palatine are a rather active, and somewhat well-known loyalist chapter of the Adeptus Astartes created during the ill-fated 21^st Founding, the so-called 'Cursed' Founding, created from the proud lineage of the Blood Angels. This Chapter is located in a grouping of systems known as the Bright Stars, which are comprised of lush and mineral rich worlds within of the Segmentum Obscurus. Their whole reason for existence is to act as the defense force and arbiters of the Bright Stars, their main objective to defend the Stars from invasion through a semi-stable warp rift in the area known as the 'Malum', or 'The Evil', as well as reinforcements, should the Cadian System, and it's Cadian Gate, required aid. Most of their active duty is spent destroying minor Chaos incursions into their system, as the both the Malum and Eye of Terror (a giant warp-rift in realspace that leads to the hellish Realm of Chaos) resides in close proximity.
Angels Repentant	Pict-File Unavailable	The Angels Repentant are an Ultima Founding chapter of the Adeptus Astartes, formed by Commander Dante following the Devastation of Baal, where the veterans of the chapter served under the colors of the Blood Angels. They operate on the fringe of the Imperium Nihilus, currently stationed in the Urhus System. Known for tactical prowess, Astartes of the Angels Repentant prefer laying bolterfire at a distance, before closing the gap to rip their enemies to shreds. After battle, these battle-brothers are known to exercise their rage through the creation of art, and as such, the chapter's fortress-monastery is known to be lined with breathtaking paintings, sculptures, and many other masterpieces.
Angels Vehement		The Angels Vehement are a semi-Codex compliant, savage descendent of the Blood Angels. Created during an unknown founding this Chapter claims to have been a part of the ancient Second Founding, when the Space Marine Legions were torn asunder and reorganised in seperate Chapters. Despite the paucity of records, these claims are considered by most Imperial scholars as dubious at best. This Chapter is known to suffer a unique gene-flaw called the 'Angel Curse', which causes those who fall to the Black Rage to become mutated, daemonic figures. They have defended the Segmentum Obscurus from the denizens of the Halo Stars since M33.
Angels Vigilant		The Angels Vigilant were a formerly loyalist Successor Chapter of the heroic Blood Angels, created during an Unknown Founding. After a xenos invasion decimated their isolated home sector, the Chapter made a deal with the Daemon Azazel, devoting themselves to the Ruinous Powers for the sake of salvation. They have re-painted their armour purple and dedicated themselves wholly to the Dark Gods. Eventually they were driven from their original homeworld and fled to the Eye of Terror. Now known as the Void Stalkers, this notorious Chaos Warband terrorize the Galaxy by launching multiple raids throughout the Materium. (Excommunicate Traitoris)
Arachnid Warriors		The Arachnid Warriors are a Codex-compliant Chapter formed during the 23^rd 'Sentinel' Founding during the 37^th Millennium. Formerly declared Renegade (Excommunicate Traitoris) from 345.M41 to 013.M42, the Chapter has since been brought back into the Imperial fold after an investigation by Inquisitorial forces determined the original charges of Heresy against the Chapter proved to be unfounded, as well as the Chapter proving it's loyalty and lack of corruption in the Hyperion War that lasted from 999.M41 to 013.M42.
Arbiters of Caliban		The Arbiters of Caliban are wrought from the strongest of steels, born of the warfare that dominated M30. They are a formidable force, born from the Dark Angels, quite possibly one of the strongest legions created by the Emperor of Mankind. Unlike their brothers, the Arbiters are not troubled by the Treachery of Luther and his fall to Chaos. Despite their apparent escape from the torments of the Dark Angels, the Arbiters still utilize their righteous fervor to further aid in both the hunt for the Fallen and in their service to the Imperium. Fate seemed to smile upon these Angels of Wrath, as they have escaped many plights suffered by their brethren.
Archangels of Manasseh		The Archangels of Manasseh is an ancient and highly respected Loyalist Successor Chapter that hails from the lineage of the heroic and stalwart Ultramarines. Created in the wake of the tragic events of the Horus Heresy and the subsequent dissolution of the Legiones Astartes, the Archangels were created during the 2^nd Founding. The Archangels of Manasseh were one of several 'Primogenitor Chapters' created during this time. The Ultramarines maintained the XIII^th Legion's original name, badge and colours, while the remaining created Chapters took new names and heraldry. Shorn of their past history and livery, the Archangels were free to forge their own path. However, due to the destruction of their planet, they have become a fleet-based chapter.
Ardent Shields		The Ardent Shields are a Codex-compliant Successor Chapter create during the 20^th Founding from the proud lineage of the venerable Ultramarines. The Ardent Shields are a Chapter whose founding was based off a need to add more numbers to the Adeptus Astartes in the Armageddon Sector while still abiding by the Codex Astartes. The Chapter was Founded near the end of M35, by a detachment of Ultramarines who had partook in the minor crusade known as the Salvation Crusade. These Astartes would form a much greater form of brotherhood with their Imperial Guard brothers which would come to define their very chapter in the centuries to come. They would soon be known for their immense sense of duty and skillfulness.
Argent Eagles		The Argent Eagles are a Space Marine Chapter created during the 23^rd 'Sentinel' Founding as a Blood Angels Successor Chapter. Hailing from the world of Auroria within the Ultima Segmentum, the Argent Eagles specialize in Void Warfare, Aerial Warfare and Decapitation Strikes via Aerial Drop Assaults. While they adhere to the Codex Astartes on some occasions they also follow their own set of rules laid down in the Legisla Auroris, a scripture that dictates the traditions, beliefs and war doctrines of the order. Having lost over 1,000 Battle-Brothers during the Devastation of Baal, the Chapter now consists of mostly Primaris Space Marines, although most of the higher ranks and offices remain staffed by those Firstborn who survived the battle, such as the Chapter Master and the Company Captains. Their love for the creation of art and beauty is outshone only by their deep devotion to the immortal God-Emperor, who is known to them as the Argent Archon.
Argent Executioners		The Argent Executioners are an Ultima Founding Successor Chapter of Salamanders descent. They have appeared occasionally throughout recent history at seemingly random points, striking swiftly from the dark to claim the heads of their enemies as trophies in the Emperor's name. They are most known for their brutal focus which leads them to inglorious, practical victories against even the most dire of foes. While they are particularly young for an Astartes Chapter, they have swiftly made themselves known as among the greatest heroes the Imperium can offer. Their many victories stand in shadow and no one truly knows how many battles they have been involved in.
Argent Leviathans		The Argent Leviathans are a semi-Codex compliant Loyalist Space Marine Chapter descended from an unknown parent Chapter that was founded during the 25^th 'Bastion' Founding. The warriors of the Argent Leviathans revel in the glory of melee combat. The Argent Leviathans rarely use the Codex Astartes and instead utilise their own strategies and structure. The Chapter mainly recruits from their homeworld, the ocean world Caerule, however, they have recently been forced to recruit from other planets due to a shortage of Astartes.
Argent Wardens		The Argent Wardens are a loyalist, semi-Codex compliant chapter from the 4^th Founding, hailing from a frozen world in the Segmentum Ultima. They are successors of the Imperial Fists and part of the Last Wall, and as such, are masters of siege-craft, being both an unbreakable, immovable shield and an unstoppable, destructive force. But, where there are many similarities between the Wardens and their parent chapter there are also unique differences. The Astartes of the Argent Wardens specialize in medical practices, believing that it's not enough to simply destroy the enemies of the Imperium, they must also guide and protect its citizens. They strive to safeguard all human life, and prioritize the lives of human comrades, believing that no man gets left behind.
Armageddon Sons		The Armageddon Sons are an ancient Loyalist Space Marine Chapter created from the vaunted heritage of the honourable Ultramarines. Officially, this Chapter was listed as being created during the 3^rd Founding, however, scant evidence indicates that this Chapter might have been created much earlier as there are scattered reports of them first appearing in the early years of M32. The truth of the matter is much darker, and is no known outside the Chapter. The origins of the Armageddon Sons actually harkens back much earlier, to a bygone age when the Imperium first took the stars and conquered the known galaxy. Unknown to anyone, save the Emperor Himself, is that the Armageddon Sons were in fact descended from a small loyalist element from the Sons of Horus that managed to hide their allegiance and escape before the events of the Isstvan III Atrocity.
Ascetics of Korit		The Ascetics of Korit are among the new wave of Space Wolves successors from the Ultima Founding. They were created from the population of the world of Korit, an isolated yet strategically significant world surrounded by warp storms in the Segmentum Tempestus. Korit is a mountainous and heavily forested world, and its unique geography and political climate have created a harsh divide between the Bakuhan (ruling elites who claim ownership of the entirety of Korit) and Iteki (rebels who reject the rule of the Bakuhan). This division has been translated into the Ascetics, and while the two factions are yet to come to blows, they remain harshly divided.
Ash Scorpions		The Ash Scorpions are a Loyalist semi-Codex compliant Space Marine Chapter and 8^th Founding Successors of the Imperial Fists Chapter. They are a proud Chapter whom try to adhere to the Codex Astartes wherever possible but have been known to disregard it if the situations warrants it. They stand as a bulwark against various threats that assail the Sigma Cluster, a volatile region located in the Ultima Segmentum, defending the worlds of the Imperium against xenos, heretic and Chaos forces.
Ash Soldiers		The Ash Soldiers are a loyalist non-Codex compliant Chapter created during an unknown founding. But comprised almost entirely of newly revealed Primaris Space Marines - the next stage of evolution of the Adeptus Astartes. Only a couple dozens of their members are Firstborn Astartes, but they work as the masters and mentors of their newer brothers. They are closely linked to the governors of the Katabruk sub-sector, having their favor and being part of their structure of power.
Ashborne Drakes		The Ashborne Drakes are a Loyalist Successor Chapter of the Adeptus Astartes created from the lineage of the heroic Salamanders Chapter. They were created during the 19^th Founding in M36, to help defend the realm of the Emperor of Mankind from the threat of both heretics and xenos.
The Ashen		The Ashen are a Loyalist Space Marine chapter of the 23^rd 'Sentinel' Founding. They are a suspected Successor Chapter of the Raven Guard. However, gene-seed analysis and records of the chapter is fragmented and missing vital sections. Due to this, the Adeptus Administratum dispute any official claim of Linagae. This Chapter is a Codex-compliant chapter that diverges in some aspects. They are a half-strength chapter, only mustering 500 fighting marines in 5 companies and they do not strictly adhere to the standard practice of Codex-proscribed markings. The Ashen are a little heard of chapter mostly adhering to their sectors of space tasked with fending off hostile incursions and pirate attacks on imperial assets and worlds.
Ashen Angels		The Ashen Angels hail from the First Founding Chapter of the Dark Angels, brought from their home world of Vespera Mortis, a death world of obsidian mountains and volcanic, ashen lands. They are well known for their brutal close-combat prowess and their connection with their fallen brothers. Their unknown gene-flaw is that of major importance to the chapter, "The Ashen Echo", which lets the afflicted see the souls and hear the voices of those brothers who have passed. Some are affected more deeply than others, being that Librarians often have psychic overloads from these visions. Despite being a primary anti-Chaos and anti-Ork Space Marine chapter, they almost suffered the fate of their fallen brothers, being nearly eradicated by the Tyranid menace. Even after much work and eradicating much of the Tyranid hive, to this day the Great Devourer is still being staved off.
Ashen Apostles		The Ashen Apostles are a Loyalist non-Codex compliant Space Marine chapter descended from an unknown parent Chapter founding during the 21^st 'Cursed' Founding. The chapter earns the distrust of other chapters simply being born during the time of the Cursed founding, however, is not the only thing that earns them the distrust of other Astartes. The Apostles preference for diplomacy rather than all-out war which has made war-loving chapters such as the Space Wolves and Black Templars dislike the Apostles even more. When in and out of battle the Apostles are some of the most fanatical worshipers to the God-Emperor of all Astartes, because of this many of the worlds the Chapter has conquered are now highly religious due to the Apostles influences.
Ashen Crows		The Ashen Crows are a Loyalist Space Marine Chapter formed during the 19^th Founding. The Ashen Crows claim to descend from the Primarch Corvus Corax and succession from the Imperial Talons Chapter. The Ashen Crows are a proud and isolated Chapter, claiming the proud heritage of their home world, Karit Tertium, with their goals aiming to strive and uphold it with honour and courage. The Chapter is known for operating with efficient skill against the Ork clans in Ork-infested space. It is rare for the Chapter itself to work with other Astartes.
Ashen Drakes		The Ashen Drakes were a part of the 21^st "Cursed" Founding. They proclaim to be scions of Vulkan and strive to be worthy of his heritage. While they hailed from a Founding plagued by genetic deviancy and ill luck, the Ashen Drakes had exhibited neither of those traits, until the formation of the Great Rift; when they were destroyed after a century-long siege of their homeworld. However, their reputation remained that of a Cursed Chapter, which had made them more isolationists than other (alleged) Sons of Vulkan, for other Astartes shunned them and the Inquisition is ever vigilant. They were still one of the most humane Chapters in existence, living among their people and helping all they could, but they knew that only the most desperate Imperial Commander would call for their help.
Ashen Heralds		The Ashen Heralds are an ancient Chapter of Space Marines of unclear origin and descent. Through the chapter’s long history of service, it has earned a reputation for fielding pragmatic, stoic marines, intent on waging war on the foes of the Imperium with a cold fury. The earliest history of the Ashen Heralds is largely unknown, much information on them was lost in the wake of catastrophic losses against the forces of Chaos that left the chapter on the verge of extinction. Through the grace of the Salamanders chapter, which loaned veterans and officers to guide the few surviving Heralds in raising the next generation of neophytes, the chapter survived and has gone on to wage war in the name of the Emperor for millennia.
Ashen Knights		The Ashen Knights are a Loyalist Codex-divergent Chapter of the Adeptus Astartes created during the Third Founding from the venerable Salamanders. Currently, they are a fleet-based chapter and operate on the borders of Imperium-held space. Their primary specialities are in the advanced search and recovery of artefacts, persons, and entities on Exterminatus-class Death Worlds.
Ashen Raiders		The Ashen Raiders are a Loyalist Chapter of Firstborn Space Marines created during an unknown Founding and of an uncertain lineage. Based in the South Eastern corner of the Segmentum Tempestus, the Ashen Raiders have a history obscured by the collection of convoluted and contradictory documents within the Adeptus Administratum that have proven even the most adept scholars of the Imperium a difficult challenge to explain.
Ashen Souls		The Ashen Souls are a msyterious Loyalist Space Marine Chapter of the Adeptus Astartes created during the mysterious 13^th Founding, the so-called 'Dark Founding', due to the lack of information on this particular founding in official Imperial historical records. Their exact lineage is unknown, however, many Imperial savants believe this Chapter is descended either from the First Founding Dark Angels or Blood Angels.
Ashen Thanes		The Ashen Thanes are one of the oldest, non-founding chapters in the Imperium. Created sometime during the 4^th or 5^th Founding, and from uncertain lineage, they were formerly known as the Iron-Bound Thanes, and are the parent chapter of the Exalted Paladins. Unfortunately most of the early records of the Iron-Bound Thanes were lost in the destruction of the Chapter's original fortress-monastery, Tol Elmoth, in M37 when the Blood God-worshipping World Eaters Traitor Legion attacked their homeworld, Taur-Hithlum. Rebuilding in the aftermath of this devastating attack, the Chapter reforged their sorely depleted ranks and renamed themselves the Ashen Thanes. Since that tragic era, the Ashen Thanes have gone on to become a well-respected Chapter. Though their Primarch is unknown and the Chapter has made no attempt to discover who it is, they have instead chosen to venerate the Space Wolves' Primarch Leman Russ as their spiritual founder. Why they do is unknown, though their home world was one of many planets brought into the burgeoning Imperium by Russ during the Great Crusade.
Ashen Wraiths		The Ashen Wraiths are an Astartes Chapter of an Unknown Founding created from the line of Primarch Corvus Corax, and like their parent Chapter, they too, are renowned as cunning and patient hunters, adept at biding their time until the moment to strike is at hand and then attack with overwhelming force that leaves their foes with no chance of resisting. Their Founding is unknown, but many suspect that it was relatively early, perhaps as early as M32. Whenever their founding occurred, the Ashen Wraiths served the Emperor with a cold, calculating and even intellectual temperament as well as possessing superb infiltration skills and skill at furious close-quarters engagements as the foes of Mankind are destroyed in a flurry of crackling lightning claws and the bark of bolters. Many a foe has considered himself safe, only to come face-to-face with the pale skin and jet-black eyes of these ruthless Astartes.
Astra Khalybes		The Astra Khalybes is a loyalist Codex-compliant Space Marine Chapter created during the 8^th Founding from the gene-seed of the Blood Angels Chapter. They hail from the death world of Shool, a planet-sized jungle filled with super-predators and where Humans are forced to live in huge fortresses to protect themselves. Most unusual for a Chapter of The Blood, the Astra Khalybes are unlike their fellow Successor Chapters, in that they have a tendency to replace lost or severed limbs with bionics. It is unknown if this is somehow ingrained into their psyche or is a result of some form of as-yet-determined genetic idiosyncrasy that has yet to be discovered in their Chapter's gene-seed. This Chapter is also known for its close ties with the Adeptus Mechanicus, and as a result, its excellent relations with the Omnissian Priesthood have garnered them expedited delivery of new arms and equipment whenever the need arises.
Astra Romana		The Astra Romana or in Low Gothic, the 'Sentinels of Ultramar', is a Loyalist Successor Chapter created from the lineage of the venerable Ultramarines. They were created during the 23^rd Founding, otherwise known as the 'Sentinel Founding', in order to strengthen the Imperium's defenses during the late 37^th Millennium. Early in the Chapter's history, they found fragments of records that were written by the Ancient Terran Romanii on one of their voyages. In order to pay homage to this civilization that was unfortunately extinct, they decided to adopt their culture into their own Chapter.
Astral Arbiters	Pict-File Unavailable	The Astral Arbiters are a formerly Loyalist Space Marine Chapter created during an Unknown Founding and from an unknown lineage. At some point, the Chapter was declared renegade by the High Lords of Terra and went rogue. They renamed themselves Blackvein's Corsairs - a band of vagabonds and greedy raiders - whose only recourse is currency. They show a marked hatred for chaos and view it as 'A fool's investment'. (Traitoris Perdita)
Astral Canids		Many have been the possible origins proposed for the Astral Canids, though none can have been ascertained. Though the Astral Canids are officially registered as part of the Fourth Founding, right after the conflict known as 'the War of the Beast' and in the context of the coup known as 'the Beheading', these records are contradictory with the battle records of that conflict, for they shown that a Chapter with the same name and livery answered to Lord Commander Koorland's summoning to enact the 'Last Wall' protocol. The Astral Canids answered to that call as all the descendants of Dorn did. However, they denied belonging to that gene-lineage. (Note: This Chapter falls under the Expanded Universe category.)
Astral Carbines		The Astral Carbines are an Ultramarines Successor chapter founded during 27^th 'Ultima' Founding, composed primarily of Primaris Space Marines. The Astral Carbines were hailed for numerous victories, overcoming hardships which would've broken most people. However, their strength and virtue did not last forever; the Astral Carbines were fractured, as the Warband Arcane Reavers was borne from the Astral Carbines' traumatizing experience in the Warp. The loyalist Astral Carbines gave their all to defeat their fallen brothers, with the final battle being on the planet of Casimus. The Astral Carbines slowly but surely rebuilt after a 25 year Penitent Crusade, with Casimus officially became the home-world of the Astral Carbines.
Astral Consuls	Pict-File Unavailable	The Astral Consuls were a formerly Loyalist Space Marine Chapter created during the 20^th Founding in late M35, from unknown lineage, as classified by the order of the Inquisition. Once noted for their fierce and meticulous fighting skills on the battlefield, this Chapter eventually fell into a tragic downfall of ill-fate, which led to the destruction of their beloved homeworld of Costov. Eventually they were declared renegades by the High Lords of Terra, and took to worshipping the Chaos God Slaanesh. Embracing the worship of the Pleasure God, they became the now infamous Chaos Warband known as the Forsworn, and now stalk Imperial space lanes, plundering and murdering as they see fit. (Excommunicate Traitoris)
Astral Fists		The Astral Fists is a Loyalist Codex-compliant Space Marine Chapter descended from the gene-seed of the unforgiving Iron Hands during the 23^rd 'Sentinel' Founding that operates within the Segmentum Ultima. Following their inception, the newly created Astral Fists were deployed to the Tarsonis Sector in the Segmentum Ultima to fight off the xenos incursion occurring there. Eventually, they claimed the cleansed Tarsonis Sector as their own demesne. Like their progenitors, the Astral Fists Chapter maintain close ties and relations with the Mechanicum of Mars and are also more interested in their tactical success rather than their battlefield glory.
Astral Giants		The Astral Giants are a mysterious Space Marine Chapter of the 3^rd Founding and uncertain lineage. There is very little information on them, and what little exists, is sealed away in the deepest vaults by the Inquisition. This unusual chapter has shown to possess numerous technologies and weaponry of the early days of the Imperium, thought loss during the Horus Heresy, as well as relic archaeotech from the Dark Age of Technology including incredible warp technology. How they came to obtain such powerful and forbidden technology is unknown. They originate from the Adamas Sector, which is positioned between the Segmentum Obscurus and Segmentum Solar. While originally unimportant and isolated, its only outstanding feature was serving as a warp route between most sectors in Segmentum Solar deep into Segmentum Obscurus.
Astral Leviathans		The Astral Leviathans is a loyalist Space Marine Chapter of the mysterious 13^th Founding, the so-called 'Dark Founding', from an unknown parent chapter. The Astral Leviathans have seen extensive combat in the outer fringes of the Imperium combating Renegade planetary governors and militias, their majority of their campaigns being waged against humanity itself, this comes into the chapters very close ties with the Ordo Hereticus and the Ecclesiarch. Rituals and the imperial creed is a large part of the chapters life, they are some of the most zealous and fanatic of the Astartes, their armor and vehicles are heavily adorned with purity seals, scriptures, and litanies of battle.
Astral Paladins		The Astral Paladins are a Loyalist 3^rd Founding Successor Chapter of the stoic Imperial Fists. The Astral Paladins formed with a focus on defensive tactics and long-range combat. The Astral Paladins were given a large amount of relic Mark III "Iron" pattern power armor upon their inception. The chapter took pride in their relic pattern battle-plate and revered it. Maintaining this precious gift from the Emperor was deemed extremely important. Due to the defensive static style of combat and a focus on - "No brother gets left behind" - the Astral Paladins rarely lose any of this relic armour and will often go to great lengths to recover these suits of armour from the fallen on the field of battle. Due to having much of it's founding armor, every Battle-Brother has at least a Mk III Helmet. The Astral Paladins have a close working relationship with the Astra Militarum and often spend a large amount of time fighting alongside these mortal Imperial forces.
Astral Ravens		The Astral Ravens are a Successor Chapter created from the rare lineage of the Raven Guard, raised during the 25^th 'Bastion' Founding during the latter half of M40. They were one of several newly created Successor Chapters to act as a bulwark against the myriad of threats that assailed the Emperor's realm. At that time, the Imperium faced more dangers than ever before; Chaos was gaining momentum, the Tyranids had smashed into the galaxy, and aliens that would have never dared defied the Imperium before were now brazenly striking out against the Imperium. Trained extensively in close-quarters warfare and veterans of dozens of close-fought campaigns, the Astral Ravens have proven to be highly effective in their chosen realm of warfare. Although a newer Chapter, the Astral Ravens have already earned a reputation for their pragmatic brutality and relentless aggression towards their foes.
Astral Reapers		When the xenos, daemons, and heretics feel themselves victorious against mankind, then come the black hooded enforcers of the Emperor's will, as silent as the dead of night, to break both the enemy's morale and bodies, and they shall gloat nevermore. They are the Astral Reapers, sons of the Primarch Corvus Corax, born during the 3^rd Founding. Having no home world to call their own and being a crusading chapter, these descendants of the Raven Guard wage stealth and guerrilla warfare against the enemies of mankind as the shadow-draped dagger of the Emperor's justice.
Astral Serpents		The Astral Serpents are a Loyalist Space Marine Chapter based in northern Ultima Segmentum at the edge of the galaxy. Being so isolated, they have very little contact with other imperial forces other than those which are in the Azeran Sector. Rarely has this Chapter been recorded in official Imperial records, and when they are the records are incredibly vague, and when young Inquisitors wanting advance in their position notice this, they head off to Viperae. Of course these Inquisitors find nothing and go back to Terra or to their masters after growing frustrated after listening to the chaplains and seers of the Serpents telling long drawn-out stories of their chapter's supposed ancient history.
Asturyan Wardens		The Asturyan Wardens are a semi-Codex compliant Loyalist Space Marine Chapter created in the 4^th Founding's final years. They are know for being very good defenders, having a large fleet, extensive use of bolters and having close relations to the Inquisitors of Ordo Xenos. But they're most famous for their attitude towards humans, who they see as the reason for Emperor's sacrifice, and thus they make their safety one of their top priorities. This attitude as made them friends and allies with the Space Wolves and Salamanders Space Marine Chapters. Originally a fleet-based Chapter, they eventually decided to settle in Kannon, a planet in the Reductus Sector.
Atavists		The Atavists are a Codex-divergent chapter of Blood Angels gene-stock, founded at the dawn of M42 during the recent Ultima Founding. As one of the chapters involved in the campaign of the Unnumbered Sons, wearing the red and black of the venerable Blood Angels. However, the chapter was quarantined and all identifiable gene-sons rounded up almost immediately after the beginning of the Indomitus Crusade before they could participate in the combined-legion offensives spearheaded by the Emperor's returned son, Roboute Guilliman. Their gene-curse was greater than that of the average Sanguinary Brotherhood Chapter and their unique logistical requirements necessitated their organization as a Chapter long before Guilliman released his Greyshields into individual service. During the Charieu War, the Atavists received censure for their actions, as they joined the heretical Silver Bolts in open conflict. Even so, their honour and an examination of their situation and mutations exonerated them from the worst punishment. The chapter was relegated to a vanguard role in the Indomitus Crusade, losing much of its independence as an Astartes chapter and its ability to recruit new marines until the end of its fleet's leg of the ongoing Indomitus campaign. A fresh chapter with a black stain on their record so soon after founding, the Atavists seek glory and prove their worth as loyal sons of Sanguinius.
Atomic Gladiators		The Atomic Gladiators, a 3^rd Founding Iron Hands Successor Chapter, are a fleet-based Space Marine Chapter that is slightly above the Codex-proscribed 1,000 Astartes, as multiple Corps groups have been spotted in multiple Segmentums across the width and breadth of the galaxy. The truth to these rumours is of extreme interest to the Inquisition, but as of yet, they have been unsuccessful in their investigations. The Atomic Gladiators are a very unique Chapter, for they possess close ties with both the Adeptus Mechanicus of the Forge World Toyotis, located in the Vandor system, and the Knight House Stark on the Feudal World of Koschei in the star system of Canum, both located in the Segmentum Tempestus. Although primarily fleet-based, the Atomic Gladiators have a Chapter Citadel on Koschei, and many other planets, as a fixed point for the Chapter.
Auric Subjugators		The Auric Subjugators, sometimes called the 'Subjugatii Aureum' in High Gothic, are a loyalist Astartes Chapter and scions of Rogal Dorn, it was once unknown as to which of the VII Legions successors they hailed from. However, it is now believed that they are successors of the Executioners with many citing the obvious similarities between the two Chapters. Founded during the 23^rd Founding, the so-called "Sentinel Founding", they are a savage, bloody-handed and barbarous Chapter, indeed many of their fellow Space Marines view them as little more than ill-disciplined primitives and gore-splattered headhunters, little better than Renegades. This opinion is well founded for the Auric Subjugators truly are bloody-handed monsters - vicious and violent beyond what is expected even of Astartes and when they are unleashed into battle, the Chapter's Astartes fight with gleeful savagery, tearing apart whatever enemy they are given to fight without mercy or falter, heedless of the risk and uncaring of the Chapters own losses.
Auricblood Knights		The Auricblood Knights are a Loyalist Chapter of the Adeptus Astartes descended from the Angels Encarmine Chapter, and by extension, Sanguinius' Blood Angels. This Chapter was created through unusual circumstances through the use of unsanctioned experiments during the 19th Founding by the Inquisition, through the use of Daemonhost possession techniques similar to those of the Exorcists to alter the presence of Astartes in the Warp. These unconventional techniques, combined with a ritual similar to the Angels Encarmine's Rite of Holos and the esoteric practice of biomechanical engineering by the Chapter's Techmarines, caused the Auricblood Knights to be highly resistant to the effects of Chaos. This made the Astartes of this Chapter significantly more resistant to their inherited gene-curse known as the Black Rage. This combined process is called Ichorgilding. However, this comes at the cost of their altered presence in the Warp amplifying the Auricbloods' more physical aspect of the Flaw of Sanguinius, the Red Thirst, with most battle-brothers often struggling to resist their cravings for blood.
Avengers of Tyran		The Avengers of Tyran are a semi-Codex compliant Ultramarines Successor comprised entirely of Primaris Space Marines with a very unique history. Shortly before Hive Fleet Behemoth ravaged Tyran, a small fleet consisting of several Tyranian Regiments was sent to assist a local PDF. Upon returning, the fleet found that Tyran was barren, and that they were the only surviving Tyranian natives. Filled with anger, the survivors organised themselves into something similar to an Aeldari Craftworld; a fleet of ships containing the surviving population of Tyran. Eventually, Guilliman founded a Primaris chapter from the survivors, and they were quickly adopted into the fleet as a force to aid the pre-existing military force of the Tyranians. To this day, the Avengers of Tyran are combating the many Splinter Fleets of Behemoth.
Azure Ravens		The Azure Ravens are a Loyalist Successor Chapter of the Ultramarines, created during the 25^th Founding, the so-called 'Bastion Founding'. This Chapter was one of several created to help stand as a bulwark against the rising tide of Chaos which was steadily gaining momentum, the voracious Tyranids, and various xenos that would have never dared defy the Imperium before and brazenly striking out against the Imperium. As inheritors of Guilliman, the Azure Ravens were once deemed for great things, however, fate and circumstance would see the Chapter fall under a cloud of long-standing suspicion and discourse. Even into the modern era, the Inquisition still considers the Ravens to be a very controversial Chapter and continuously keeps a close eye on them whenever possible.
Azuri Astra		The Azuri Astra are a loyalist Chapter created during the 16^th Founding from the gene-seed of the Ultramarines. The Azuri Astra have dedicated themselves to the recovery, preservation and study of historical relics, artifacts and documents. They seek the history and the knowledge of the milky way galaxy, striving to understand bygone human civilizations in order to piece together an accurate account of humanity's shrouded past. Conducive to this goal are the Chapter's specialties of infiltration, information gathering and the rapid extraction of valuable artifacts or individuals. In addition, the balanced doctrines of the Codex Astartes have ensured that they can accomplish their missions through either swift covert operations or heavy shock assaults. In order to avoid conflict with certain branches of the Inquisition and the Ecclesiarchy, the Chapter has always maintained that their purpose is merely to research the history of their own order and that of Ultramar. In reality, they have long sought the truth behind the history of all mankind, including what some would consider to be "forbidden" knowledge.

Name	Image	Notes
Baleful Boars		The Baleful Boars is a very small and endangered Loyalist non-Codex compliant Space Marine Successor Chapter created from the lineage of the Blood Angels Space Marine Chapter during a unstated founding at the end of M37. It was created to counter the threat of the 7^th Black Crusade in 811.M37, when Abaddon the Despoiler and his forces assaulted the Segmentum Obscurus. Since their inception, the Baleful Boars have writ a blood-soaked saga of fell deeds and numerous atrocities down the long millennia of their existence. The Chapter's detractors often point out that these ferocious Astartes appear every bit as savage and merciless as the heretical World Eaters Traitor Legion. Walking a precarious path between purity and damnation, only time will tell whether or not the numerous excesses committed by the Baleful Boars in the Emperor's name will be their downfall, and eventually they are declared renegades by the High Lords of Terra.
Baleful Paladins		The Baleful Paladins are a Loyalist Successor Chapter descended from the esteemed and Mysterious Dark Angels of the Primarch Lion El'Jonson's bloodline. This Chapter is composed entirely of Primaris Space Marines, created during the most recent Ultima Founding by the recently awakened Primarch Roboute Guilliman. Operating in the Hexad Sub-Sector of the Milletatron Sector, the Baleful Paladins are highly active at prosecuting the wars of the Imperium against the myriad of enemies of Mankind. Like most of their allies of the Unforgiven Chapters, the Baleful Paladins are driven to prosecute the Dark Angels' secret war against The Fallen and are more than willing to answer their progenitors' call to war to achieve their objectives.
Battencian Heralds		The Battencian Heralds are a Loyalist 24^th Founding Successor Chapter of the Adeptus Astartes whom are descended from the proud lineage of the First Founding Ultramarines Chapter. Despite their heritage as being Scions of Roboute Guilliman, one would assume this Chapter has a preference for shock assault and close-quarters tactics. But surprisingly, this is actually the Chapter's secondary focus, as they prefer to make use of mass-theatre fire and maneuver tactics. Despite their differences with their fellow Chapters of the Blood, the Battencian Heralds are a noble and proud Chapter. Despite their relative youth as far as Astartes Chapters go, their many hard fought battles and heroic victories have given them a reputation suitable for a Chapter much older than they are.
Bears of Kalum		The Bears of Kalum is an Imperial Fists Successor chapter, that was founded during the peak of the 8^th Founding to bolster the presence around the Eye of Terror. A Codex-compliant chapter, their primary duty is defending and patrolling the northern Gothic Sector. Over their long watch of the sector, their rather unfortunate proximity to the warp storm "Storm of the Emperor's Wrath" became apparent. The following chaos incursions and warp storms would've broken most chapters, this only hardened their resolve to defend their world and their space. This resolve has become the quality the Bears of Kalum are known for, however, it has gotten them into numerous bloody conflicts with their rather intense and stubborn defense of worlds, refusing to withdraw out of a sense of duty and morality.
Bears of the Claw		The Bears of the Claw are a strange, but Loyalist Space Marine Chapter of the 20^th Founding, created from unknown lineage. The Bears of the Claw are mostly known for their spirit, respect and determination, but are also known for being very devastating in combat. Unlike other Chapters, the Bears of the Claw did not possess the usual number of 1,000 battle-brothers, instead numbering around 700. For two millennia, the Bears fought with only seven companies, per Chapter tradition, refusing to reconstitute their three lost companies. But despite their smaller size, the Chapter's ferocity and stubbornness in the face of overwhelming odds, more than made up for their lack of numbers. It wasn't until the dawn of M42, and the advent of the newly revealed Primaris Space Marines, that the Chapter was finally able to reconstitute their long lost companies.
Black Devourers		The Black Devourers are a former Loyalist Space Marine Chapter created during an Unknown Founding. Extant evidence points to this Chapter hailing from the proud lineage of the noble Rogal Dorn. Within only a few centuries, the chapter was discovered using Chaos-tainted artifacts by the Inquisition. The end result was the Chapter was declared 'Renegade', their homeworld destroyed and they were forced to flee, falling further into Chaos. Finding refuge within the hellish realm of the Eye of Terror, the Black Devourers became fully corrupted by the insidious touch of the Ruinous Powers, becoming a full-fledged Chaos Warband. To the shame of all Scions of Dorn, the fallen Black Devourers are descended from their lineage. They are one of the arch-foes of the Iron Blood Chapter, a mutual feeling. (Excommunicate Traitoris)
Black Fangs		The Black Fangs are a Loyalist Space Marine Chapter. Created during the recent Ultima Founding, their founding purpose is to track down and eliminate the insidious Forces of Chaos after the Night of a Thousand Rebellions, which has forged them into specialists at dismantling chaos cults across the stars. As a non-Codex compliant Chapter, The Black Fangs are split into two Companies. The Vanguard is sent to confront large-scale rebellions, using shock and awe to crush armies. The Maroon Squads engage smaller forces in guerilla campaigns employing stealth and fear tactics. Together, The Black Fangs purge any trace of corruption from the worlds they visit.
Black Huntsmen		The Black Huntsmen are a chapter of no official founding that split from the ranks of the Mortifactors of Roboute Guilliman's lineage in the intermmediary period between the Second and Third Foundings that was passed by Imperial Edict. During the years of the Horus Heresy they served as the First Company of the Sixth Legate's chapter of the Indominable Legion and were bloodied during the Underworld Wars on Calth against the Word Bearers. At the breaking of the legions, the Ultramarines broke their ranks into their component chapters, among them were the Mortifactors whom the nascent Black Huntsmen were seconded to and would later split from decades later. Like the Sons of Medusa in millennia to follow, they split from the Mortifactors and the chapter came to descend on the world of Ibrosia: a feudal frontier world orbiting the gas giant of Modronos. They are characterised by their bizarre collection of beliefs that feature in the chapter's cult and culture, among them their mortuary cult, their bonding and pairing of battle brothers in a manner like the Sacred Band, the cold-hearted calculus of their fellows in the Indominable Legion with all of the malice of the Night Lords.
Black Knights		The Black Knights are an ancient and proud Loyalist Space Marine Chapter created from the lineage of the secretive and mighty Dark Angels Legion of old. They were created during the Second Founding following the dissolution of the Space Marine Legions after the events of the Horus Heresy. A fleet-based crusading Chapter, they follow in the footsteps of the Lion and their Progenitors, and will not rest until every single Fallen Angel has been hunted down and brought back to the Rock, interrogated, and granted extreme unction. As a crusading Chapter, their doctrines, traditions, and organisation reflect their particular approach to prosecuting the Imperium's wars. The Black Knights are wont to become embroiled in battles that other forces would have little hope of winning. They are unrelenting in their persecution of the Emperor's foes, reserving a particular loathing for the Traitor Legions and those who make truck with the Ruinous Powers. The Black Knights absolutely refuse to retreat in the face of any foe, however, this stubbornness has often come at a high price. The Astartes of this Chapter are grim and dour, with all their warriors wearing battle-plate of jet-black and deep red. Extant reports, however, indicate that this Chapter wields all manner of ancient relics and holy patterns of armour, weapons, and vehicles not commonly seen on the battlefields of the modern era.
Black Reapers		The Black Reapers are a semi-Codex compliant Loyalist Space Marine Chapter of an unknown gene-seed, having much of their ancient history having been lost. They heavily favour the usage of terminators in combat, and as such, they have become venerated items in the chapter's armoury, alongside their dreadnoughts. They roam the stars in their massive star fortress the Bastion of Hope, forging a reputation for helping individuals in strife, even going against orders of authority to help those in strife, and many people who fight for the imperium look to the skies in times of trouble, awaiting the time when drop pods should rain down, delivering the Emperor's justice.
Black Rhinos		The Black Rhinos are a Loyalist Space Marine Chapter created during the most recent Ultima Founding and comprised entirely of Primaris Space Marines. They were assigned to replace the recent loss of the Rhinos Chapter during the Ouroborean Predation in 990.M41 following the emergence of the galaxy-spanning warp rift known as the Cicatrix Maledictum. Two hundred Primaris of the Unnumbered Sons bore the lineage of the now believed lost Chapter. After several decades, the lost Rhinos finally returned to their Chapter home world and found themselves effectively replaced by the upstart Primaris. Tensions rose between the two factions which resulted in a handful of skirmishes breaking out and the eventual expulsion of the small contingent of Primaris Space Marines from Yekna Prime by their elder brethren. It was not known for several decades what fate befell these ousted Primaris Rhinos or what became of them, however, tales soon emerged of black-clad Primaris resembling the Rhinos. They called themselves the Black Rhinos and were later officially recognised by the High Lords of Terra as their own Chapter.
Black Thorns		The Black Thorns are 10^th Founding Chapter descended from the Iron Hands. This battle-hardened chapter's first duty as a chapter was watching over the volatile Infernus Sector, known for its proximity to a Minor Warp rift known as the Fracture. The High Lords of Terra feared that the Fracture would one day serve as a gateway for the forces of Chaos, and their fears were justified when the Fracture unleashed a horde of Daemons upon the Black Thorns' homeworld of Lorem. The young chapter barely managed to defeat the Daemons, losing more than three-quarters of its forces in the process. But from that day forward, the Black Thorns became known as the heartless warriors they are now, believing that the cold, hard strength of steel shall always triumph over the Ruinous Powers
Black Void		The Black Void are a renegade Space Marine Chapter created during the 21^st "Cursed" Founding of M35, hailing from White Scars lineage. The Black Void were a fleet-based Chapter, roaming the galaxy to protect the Imperium from the forces of Chaos. They became renegades out of bitter resentment of the Imperium. The Chapter was constantly ridiculed and undermined by other Imperial forces, losing numerous glories and gaining an increasingly poor reputation. Becoming frustrated with their treatment by the Imperium, they chose instead to strike off on their own. (Traitoris Perdita)
Blade Spectres		The Blade Spectres are a Loyalist Space Marine Successor Chapter descended from the lineage of the shadowy Raven Guard. They are a newer Chapter comprised entirely of newly-revealed Primaris Space Marines. They were created as a part of the recent Ultima Founding to take part in the Indomitus Crusade and to stand as a bulwark against the enemies of Mankind.
Bladehounds		The Bladehounds is a loyalist Space Marine Chapter founded during the Ultima Founding as a fleet-based chapter. Offically they are descended from the venerable First Founding White Scars, but studies of their gene-seed and tactics have left unfortunate rumours to circulate about them. The Bladehounds are known for their martial skill in close-combat, with most battle-brothers of the chapter being reputable chain-sword duelists, and are noted members of the Tempestus Wardens, a coalition of chapters founded in the aftermath of the Ruinous Crusade.
Blades of Dorn		The Blades of Dorn are a proud Chapter descended from Imperial Fists lineage, created as a part of the 12^th Founding during the tumultuous centuries of the Nova Terra Interregnum in M35. Since their inception, this Chapter has earned the respect of their forebears through their courage, battle prowess, and centuries of service in the Emperor's name. However, there once was a time that the Blades' loyalty was called into question, for it is to the Chapter's eternal shame that they are successors of the formerly loyalist Crusaders of Dorn, who were corrupted after entering the Eye of Terror in 321.M37, as part of the Imperial Abyssal Crusade, and reemerged centuries later in 112.M38, as the Chaos Warband known as the Brotherhood of Lethe.
Blades of Elysium		The Blades of Elysium are a 4^th Founding Chapter rumored to be descended from unknown gene-seed, but they are officially recognized by the Imperium at large as Ultramarines descendants. However, they are not on good terms with the Ultramarines or their Successors due to the fact that do not follow the dictates of the Codex Astartes. There is a mutual agreement that they will put aside this animosity for the greater good of the Imperium when possible. Only the current Hegemon knows the true story of their ancestry, told by an Inquisitorial Representative in the year of their ascension to the office. This Chapter is known to have an air of arrogance or superiority that sometimes to rub others the wrong way.
Blades of Korenaga		The Blades of Korenaga are a Codex-compliant Loyalist Space Marine Chapter, proud successors of the noble Blood Angels and, in every sense of the word, the watchers on the wall. Formed during the 15^th Founding at an unspecified year in M35, the Blades of Korenaga have spent the past few thousand years safeguarding the Imperium from the primary enemies that they face in the north - namely Chaos, Aeldarii and the Orks. The Aeldari in particular have historically been an enemy of the chapter, but with incursions from the Tyranids and Chaos warbands appearing everywhere because of the formation of the Great Rift, the two factions have set aside their quarrels to deal with the bigger threats.
Blades of Morkai		The Blades of Morkai are a non-Codex compliant chapter, who hail from the lineage of the ferocious Space Wolves, created during the Ultima Founding. Their chapter is composed of entirely Primaris Space Marines - created to help defend the besieged Imperium, to be their sword to strike against the Archenemy and xenos. The Blades of Morkai have earned a reputation to be savage, yet decisive assaults. Though they are known for close-quarters combat, like their parent chapter, but they are also known to use lightning assaults, and shock & awe. Preferring to hit there foes with fast and unexpected assaults, assaulting the enemies from two different directions, while their foes are distracted by these assaults, the main force strikes down the middle of both assaults.
Blades of Onyx		The Blades of Onyx are a mysterious band of mercenary Astartes that have exiled themselves from the Imperium and sell their services to Rogue Traders and various xenos races. Their origins are unknown to the modern-era Imperium, however some Imperial scholars point to extant records and various eye-witness accounts, placing them throughout various events that have occurred throughout Imperial history for the last ten millennia. This would mean that their true origins more than likely harken back to the dark days of the Horus Heresy during the Age of Darkness. (Fedelitas Tenebrae)
Blades of Redemption		The Blades of Redemption are a Loyalist Successor Chapter that hails from the proud lineage of the vaunted Ultramarines. Created during the 22^nd Founding in the early decades of M37, there is little official information on this obscure Chapter in official Imperial records. The Chapter is renowned for its absolute adherence to the dictates of the Codex Astartes, the likes which is unheard of in many other Chapters -- including their genetic forebears.
Blades of Resurgence		The Blades of Resurgence are one of the many loyalist and Codex-compliant space marine chapters created from the gene-seed of Rogal Dorn, primarch of the Imperial Fists. Born from the much-neglected 17^th Founding, the Blades of Resurgence are perhaps one of the most noble and valiant space marine chapters to have ever existed. However, they do have a hatred of the also prideful Reclaimers of Dorn, creating a little rift between various factions and organisations of the Imperium.
Blades of the Lion		The Blades of the Lion are a 3^rd Founding Loyalist Successor Chapter of the lauded and venerable Ebon Knights, whose lineage hails from the ancient Dark Angels Chapter. Their adopted homeworld, Havenfell, lies near the southern rim of the Imperium, and their mountain-top fortress-monastery takes the form of a mighty Imperial cathedral, it's great spire piercing the clouds. This Chapter has garnered a reputation as being honourable to their allies and implacable to their foes. Their valiant record of heroic deeds stretches back several millennia and is enviable by even some Chapters of more ancient provenance. Despite their laudable record however, like their forebears, the Blades of the Lion are also considered outcasts amongst the Dark Angels Successor Chapters - collectively known as the Unforgiven - for they were one of the few Chapters to stand by the actions of their genetic forebears, when they had the temerity to disobey the orders of the First Founding Dark Angels during the lamentable Crimson Blade Campaign. For their actions, the Blades have also been given an outcast status and are counted amongst those known as 'The Forgotten'.
Blades of the Phoenix		The Blades of the Phoenix were a Loyalist Space Marine Chapter descended from the noble and vaunted lineage of the Ultramarines, created during the Second Founding from the CCLXII^nd Battalion of the then Ultramarines Legion. Originally a beacon of nobility and hope, much like their progenitor, the Chapter slowly spiralled into disgrace and censure. Redeemed after a lengthy penitence and somewhat restored, albeit never to their former heights, the Chapter was eventually destroyed by a Tyranid splinter fleet in the twilight years of the 41^st millennium. Their legacy would endure through the Onyx Phoenixes, which would incorporate a small number of survivors into their ranks. The new Chapter would also inherit some of the equipment and model elements of their colour scheme and heraldry on the fallen chapter, in honour of their legacy.
Blades of the Wolf		The Blades of the Wolf are a formerly Loyalist Space Marine Chapter, created during an Unknown Founding. Though they claim lineage from the Dark Angels, in actuality their heritage hails from that of the Luna Wolves. The reason for the chapter being deemed as heretics was due to their attempts at reversing-engineer xenos technology to better combat the enemies of Mankind. However, the chapter did so without the consent of the Adeptus Mechanicus or the Ecclesiarchy, committing the unforgivable sin of Maletek Incarna. The chapter was deemed heretics around 990.M41, in which an Ecclesiarchy-backed fleet decimated the chapter's own fleet, leaving only the Battle-Barge known as The Unyielding Tide relatively intact. Though officially declared as 'Renegades' by the High Lords of Terra, the Blades of the Wolf continue to fight on behalf of the Emperor.
Blazing Hearts		The Blazing Hearts are a Space Marine Chapter created during the mysterious 13^th 'Dark' Founding using the gene-seed of the White Scars, making them the sons of the mighty Khan. Their homeworld, Zhoushala, is located at the western edges of the Ultima Segmentum, near the planets of Ryza and Golgotha. The Blazing Hearts excel in striking the enemy quickly from orbit via Drop Pods and butchering their way through the enemy with chainsword and flamer in hand, laughing with delight as they inspire their allies through their presence. With the opening of the Great Rift, the Chapter homeworld found itself enclosed in a warpstorm extending into realspace from the depths of the Maelstrom. As a consequence, the Blazing Hearts were completely isolated from the wider Imperium when they were assailed by an Ork WAAAGH!. It was only through the arrival of Primaris reinforcements that the Chapter was able to survive, leading to half of the Chapter currently consisting of the newer strain of Astartes. While the more severe effects of the warp storm have subsided, Zhoushala still struggles with psychic disturbances and occasional daemonic incursions, ensuring that the Chapter's skills against the Neverborn remain sharp.
Blood Bearers		The Blood Bearers are a loyalist Space Marine Successor Chapter of the bloodline of Sanguinius, created during the dawning of M32 during the 3^rd Founding. An extremely reclusive chapter, the Blood Bearers are stoutly bound to the Blood Angels, united by the blood of their Primarch Sanguinius that flows through their veins and ancient traditions that outsiders find difficult to understand. Their loyalty to the memory of their Primarch transcends all other duties and concerns. Being born from the Blood Angels' gene-seed, the Blood Bearers also carry the Flaw inherent in their gene-stock. The Blood Bearers do not deny their blood-lust, and in turn have learned to embrace it, making it a central part of their rituals. The Chapter thereby seems to have achieved an unparalleled level of restraint over their Flaw.
Blood Drakes		The Blood Drakes are a Successor Chapter created from the lineage of the Salamanders. Initially, they were raised during the ill-fated 21^st Founding, the so-called 'Cursed Founding' in 991.M35. In the modern era, they are comprised almost entirely of Primaris Space Marines after they suffered great losses stopping a brewing Ork WAAAGH! in late M39. Trained extensively in close-quarters warfare and veterans of dozens of close-fought campaigns, the Blood Drakes have proven to be highly effective in their chosen realm of warfare. Although a newer Chapter, the Blood Drakes have already earned a reputation for their pragmatic brutality and relentless aggression towards their foes, especially Greenskins, earning them the nickname 'Ork Hunters'.
Blood Fist Templars		The Blood Fist Templars is a Loyalist Space Marine Chapter formed during the Ultima Founding to address the Tyranid threat. They are formed by ancient Black Templars who were unpleased with the functioning of their chapter structure, seeing it as inadequate to serve loyally the Emperor. But the Primaris Marines that are created to serve under this new chapter's banner are born from the lineage of Rogal Dorn and are therefore officially regarded as Imperial Fists successors. This young chapter had a rough debut with many losses but has mastered the art of mobile warfare with their tanks and the exclusive use of Impulsors as troop transport. Also, their two special operations companies have proven handy in many situations that seemed desperate even for the armoured forces. They are bound to traditions and honour their ancestors as a son would honour a wise father but they are fierce with the enemy, ruthless with their homeworld people and harsh to themselves.
Blood Guard		The Blood Guard are a 11^th Founding Successor Chapter created from the lineage of the stoic and unforgiving Iron Hands. Upon their inception this Chapter was assigned the task of searching out and eliminating the heretic, the traitor, and the xenos. They have a high success rate with less collateral damage. Seeking out and purgation of these threats is not all that they are capable of, and often, the Blood Guard is called upon to intervene in various Imperial crusades and conflicts.
Blood Hounds		The Blood Hounds are a Loyalist Space Marine Chapter created during an Unknown Founding sometime in M37, whose genetic lineage is believed to come from two notable First Founding Chapters (although not confirmed) - the Space Wolves and the Blood Angels. They were made as a standing force against the Khorne-worshiping berserkers and the feral Orks who invaded their planet long ago. The Blood Hounds are a violent and deranged Chapter, as most recruits are near feral and only listen to the "alpha-male" who leads these bloodthirsty battle-brothers. They prefer to use shock-and-awe tactics and lighting warfare being able to appear like a thunder storm or more related to a category five hurricane before disappearing like the wind. Due to their bellicose nature and unusual display of lightning-like, psychic abilities, they are kept under the ever-watchful eye of the Inquisition.
Blood Hunters		The Blood Hunters are a loyalist Space Marine Chapter formed during an unknown founding. While it is known they are descended from the Sanguinius, due to lost history, it is unknown which chapter they are successors of directly. Originating from the death world of Nionus, the Blood Hunters Chapter has trained their new recruits in the aggressive way of their people trained to hunt and eliminate their enemies with extreme brutality. Using aggressive stealth tactics to break down the enemy's defenses before fast striking waves of marines charge the enemy. They tend to favor close-quarters combat but are known to use ranged attacks to harass the enemy as well.
Blood Jaguars		The Blood Jaguars are an extremely violent and savage Loyalist Successor Chapter created during an Unknown Founding sometime in M34 from the brutal and unforgiving Flesh Tearers, a Second Founding Successor Chapter of the heroic Blood Angels. Like their progenitors, the Blood Jaguars are known for their bloodthirsty nature in battle, ill-temper and bellicose nature. Though staunchly loyal to the Emperor and dedicated to their duty as protectors of the innocent, they are heavily afflicted by the genetic twin-flaws of their Primarch Sanguinius. The resulting brutality has led to their investigation on charges of heresy by the Inquisition on multiple occasions, though they have been cleared of suspicion at present. Like their genetic forebears, the Blood Jaguars are known for their bloodthirsty nature in battle, ill-temper and feared for the flaws of the Black Rage and Red Thirst that greatly affect them.
Blood Jaws		The Blood Jaws are a formerly Loyalist Chapter of Space Marines created during an Unknown Founding, and from uncertain lineage, in 013.M37. This bellicose and ferocious Chapter was created in order to stand as a bulwark against constant attacks in and around the Eye of Terror, from both the Forces of Chaos and various xenos threats. Unfortunately, within the first century of their creation, the Chapter fell from the light of the Emperor, for unknown to them, their first Chapter Master had been corrupted by a Greater Daemon of Khorne. Following their ill-fated sojourn into the Eye of Terror, the Blood Jaws was slowly corrupted by the insidious touch of the Blood God. When they finally emerged, they had been transformed into a large Chaos Warband, wholly dedicated to slaughter and murder. Now they commit the most obscene levels of carnage wherever they go, in tribute to their brutal and bloody deity. (Excommunicate Traitoris)
Blood Knights		The Blood Knights are a proud and noble order hailing from the valiant Angels Sanguine, making them of the gene-stock of the venerable Sanguinius. Priding themselves on personal honor and the ways of the knights of old, the Blood Knights are known for their valorous actions against all enemies of the Imperium. The blood Knights are also known for their compassion to the non-Astartes of the Imperium, a rare trait in M41. (Note: This Chapter falls under the Expanded Universe category.)
Blood Reavers		The Blood Reavers are a loyalist Codex compliant Space Marine Chapter of the bloodline of Guilliman, created during the 26^th Founding in 738.M41. The Blood Reavers are known for their obsession with purity and ruthlessness in battling heretics, leaving little to no trace of their enemies' existence. Their chapter is organized around blood rites, and some Blood Reavers succumb to a sleep-inducing condition which exposes their minds to the warp and renders most of its victims mad or with severe psychosis.
Blood Scorpions		The Blood Scorpions are a loyalist Space Marine Successor Chapter of the bloodline of Sanguinius, created during the 6^th Founding, which occurred sometime during the latter years of M33. Extant evidence suggests that the Blood Scorpions were one of several Chapter founded in the wake notable event known as 'The Year of Ghosts'. Throughout their existence, the Blood Scorpions have garnered a brutal reputation for being savage and unrelenting fighters. This Chapter is also notoriously intolerant of all xenos, believing them to be a blight upon the galaxy. They adamantly believe that it is Mankind's manifest destiny to vanquish all the vile and wicked alien races, and to take their place as the rightful inheritors of the galaxy.
Blood Seekers		The Blood Seekers is a Loyalist Successor Chapter comprised entirely of Primaris Space Marines, created from the lineage of the Space Wolves Chapter and raised during the Ultima Founding of 999.M41. The Blood Seekers were created after the end of the Indomitus Crusade and tasked with seeking and destroying a daemon host within both the Segmentum Tempestus and Segmentum Ultima that had overrun Imperial Army and Naval Assets in the region. With their Chapter formed as brutish shock troops, with a strict deployment to locate and destroy heavy positions of daemonic hordes. However, the Blood Seekers took a specific approach to focus their efforts to hunt the various cults of the Thousand Sons that ran rampant in these two Segmentum.
Blood Serpents		The Blood Serpents were founded as part of the 12^th Founding during M35 as a Successor Chapter to the venerable Blood Angels. Nearly a millennium after their Founding, they were beset by a series of disasters that saw the Chapter's numbers severely depleted, to the point where there were only three remaining battle-brothers. Despite talk of disbandment, the remaining survivors resolved to rebuild their nearly-extinct Chapter back to its former glory. The Chapter vanished, due to emergent warp storm activity, and was believed lost. However, in 584.M41, a new warp storm activity in the Chapter's home system appeared, and the Blood Serpents had a whole Chapter once again. However, due to the process utilised to recreate their sorely depleted numbers, they unexpectedly developed several idiosyncrasies unique to their Chapter. It remains to be seen, whether or not these genetic flaws will be the Chapter's undoing.
Blood Vultures		The Blood Vultures are a Loyalist Space Marine Chapter of the bloodline of Sanguinius, supposedly created during the mysterious 13^th Founding, the so-called 'Dark Founding', which occurred sometime between M35 and M36. The Blood Vultures have garnered a dark reputation for being savage and unrelenting fighters. It is even believed by some that this powerful and robust Chapter is as mighty as their Progenitors. Although the Blood Vultures are unswervingly loyal to both the Emperor and the Imperium, their brutal deeds, sheer savagery and merciless ways when conducting their campaigns, have writ a bloody-handed and fell reputation across the annals of Imperial history. This has often caused them to be untrusted by various Imperial organisations as well as other Chapters of the Adeptus Astartes. Unknown to outsiders, they were incepted directly from the Gore Vultures, a formerly loyalist 8^th Founding Successor Chapter also created from the lineage of the Great Angel. Terse of word and fell of deed, the Gore Vultures were distinguished by their potential for wanton carnage. Considered pariahs amongst the Sons of Sanguinius, only on the rarest occasions did this bellicose Chapter begrudgingly serve alongside their fellow successors. Sadly, their excesses eventually drew the wrath of the High Lords of Terra, who declared the Chapter as renegades. Following this declaration, the Gore Vultures disappeared from the annals of Imperial history. If the rumours are true, then the Blood Vultures' genetic lineage might likely have somehow played a role in the Chapter's barely controlled battle rage and headstrong desire to shun those they should call allies.
Blood Wights		The Blood Wights are a Loyalist Space Marine Chapter and successors of the Blood Angels' Primarch Sanguinius. They were created in M33 as one of the chapters of an unstated Founding. Their first assignment was to assist the Inquisition in cleansing heretics from the Feral world of Reynesfere and its surrounding planets in what was known as the Redemption of Reynesfere. They were awarded the feral world after the successful purging and took root on the planet, maybe more so than was expected. Blood Wights are known for their divergent beliefs, specifically their unusual reverence for a figure of the past known as Lady Forlorn. Despite their exotic beliefs, Blood Wights proved to be steadfast allies and faithful servants of the God-Emperor throughout the millennia. Blood Wight's existence has been riddled with numerous calamities, tragedies and checkered events, but they always endure and stand ready to battle the enemies of Imperium.
Blood Wraiths		The Blood Wraiths are a Loyalist non-Codex compliant Success Chapter that hails from the lineage of proud and heroic Blood Angels. Created during the 3^rd Founding at the dawn of M32, like many Chapters created from the lineage of Sanguinius, the Blood Wraiths proved to be highly susceptible to their progenitor's 'Twin-Flaws' of the Black Rage and the Red Thirst. Desperate to find the means to save his Chaper from inevitable extinction, Chapter Master Lazarus Kaine made a fateful decision in early M34 when fate intervened and he was presented with the means by which to save his sorely depleted Chapter. However, this decision would have far-reaching consequences for the Chapter.
Blood of Vulkan		The Blood of Vulkan is a loyalist non-Codex compliant Space Marine Chapter of the Adeptus Astartes created during an Unknown Founding and of dubious origins. A bellicose and ferocious Chapter, these Astartes have developed unique abilities that enables them to be nigh unstoppable in close melee combat. These abilities include pyrokinetic breath that allows them to breathe fire and the ability to call upon the inherent rage of their Primarch, making them unstoppable berserkers.
Bloodied Hunters		The Bloodied Hunters are a loyalist Space Marine Chapter created during the recent Ultima Founding during the closing years of M41 from the lineage of their mighty Primarch Leman Russ. This Chapter was created as one of several descendant Fenrisian Chapters from the line of Primarch Leman Russ, making up the unofficial collective known as the 'Sons of Russ' - to stand eternal vigil over the Imperial sectors that surround the Eye of Terror from the Forces of Chaos and encroaching xenos raiders. Like their namesake, the legendary wolf of Fenrisian mythology known as the Bloodied Hunter, this Chapter has garnered a fearful reputation as tireless pursuers and relentless hunters of the enemy - waiting patiently for the opportune moment to strike.
Bloodmoon Hunters		The Bloodmoon Hunters are a stalwart and dedicated non-codex compliant Loyalist Space Marine Chapter created during the 13^th Founding, the so-called 'Dark Founding'. Little is known of this mysterious founding as there are no reliable records that indicate how many Chapters were conceived during this Founding or what became of them. Extant records indicate that the Bloodmoon Hunters were supposedly created during this Founding around the time a recorded prophecy foretold their inception. It is generally believed that the Adeptus Mechanicus might have played a role in the creation of this Chapter, as their inception occurred sometime in early M35, during the divisive and widespread doctrinal conflict known as the Moirae Schism. The Bloodmoon Hunters were known to maintain close ties with the Archmagos of the Cult Mechanicus as well, receiving a wide diversity of arms and weaponry, including power blades and relic weaponry of the finest quality and rare, advanced patterns of armoured vehicles and gunships.
Bloodsworn	Pict-File Unavailable	The Bloodsworn are a formerly Loyalist Space Marine Chapter created from unknown lineage during the 4^th Founding in the middle-centuries of M32, following the near-disastrous War of the Beast. Tragically, this Chapter's service to the Emperor of Mankind was very brief, as after only a few decades, there were reports of this Chapter's overzealous prosecution in their duties, leaving formerly rebellious worlds as bloody abattoirs in the wake of their planetary assaults. After being declared renegades, this Chapter has embraced their status as outcast, launching periodic raids against Imperial merchant vessels and isolated worlds. They also work as mercenaries for hire for unscrupulous heretics. (Traitoris Perdita)
Blue Flames		The Blue Flames are a Codex-Divergent loyalist Chapter of the Adeptus Astartes, a 10^th Founding successor of the proud Ultramarines bloodline. They reside in the Domus Caeli, an aerial Fortress-Monastery above the surface of Gertlysh, which in turn is (officially) a feral world in the Devotio Sector, more specifically Sub-Sector Heradea. These Astartes are notable for being the first of the forces in the tight-knit Devotio Sector to receive Belisarius Cawl's Primaris Marines, as well as their unusually close relationship with the Nerva Dynasty of Rogue Traders.
Blue Widows		The Blue Widows are a formelry Loyalist Space Marine Chapter created during the ill-fated 21^st Founding, the so-called 'Cursed Founding', sometime during M36. Like many of their fellow Chapters created during this time, they were plagued by aberrant gene-seed and extensive mutations. Deemed by the Inquisition as an abomination, the Imperium declared the stalwartly loyalist Chapter as renegades. The Chapter was forced to flee their home world of Draix, leaving the to its pre-ordained destruction by Exterminatus. Cast out from the light of the Imperium, the Chapter was forced to live the outskirts of known space within the mysterious region known as the Halo Stars. When the finally emerged centuries later, they were no longer the once-proud Blue Widows, for they had wholeheartedly pledged themnselves to the ruinous powers. Now known as the Fallen Widows, the vengeful Chaos Warband vowed to enact their vengeance upon those that cast them out and drove them from their former homeworld. (Traitoris Perdita)
Bolts of Dorn		The Bolts of Dorn are semi Codex-compliant Successor Chapter created from the proud stoic and stalwart Imperial Fistss during the 4^th Founding in the mid-500s.M32, following the end of the infamous War of the Beast. The Chapter was created as an expansion to rebuild many lost chapters of Imperial Fists lineage and other 2^nd and 3^rd Founding Successor Chapters. The Bolts of Dorn was also created to counter myriad threats from the Segmentum Ultima, be it the Forces of Chaos from the Maelstorm or the marauding Orks and the newly emerged Necrons and T'au Empire.
Bone Reapers		The Bone Reapers are a Loyalist Successor Chapter created from unknown genetic lineage in late M40, during the 25^th 'Bastion' Founding. Formerly known as the Revenant Lords, this young and bellicose Chapter soon garnered an infamous reputation for savage displays of barbarity and unsubstantiated rumours of bloody rituals. After several centuries of such behaviour, they were formally censured by the High Lords of Terra. The Chapter's true nature was brought to light in 910.M41, almost by accident, during the events of an Imperial campaign, when nearly their entire 1^st Company manifested the symptoms of the Blood Angels' genetic curse, known as the Black Rage. Their shame revealed to all, they later met with the Blood Angels High Chaplain Astorath the Grim, who revealed the truth of the Chapter's genetic lineage. Embracing their heritage as one of the many Chapters of the Blood, the Revenant Lords renamed themselves the 'Bone Reapers'. Slowly accepting their progenitor's traditions and customs, the Chapter still struggle to curb the worst excesses of the Chapter's inherited warrior culture and blood practices.
Braves and Bolds		The Braves and Bolds are a Loyalist Successor Chapter from the 23^rd 'Sentinel' Founding, descendant from the genetic lineage of the Ultramarines. Originally a fleet-based chapter, the Braves and Bolds found a homeworld in Bristol, a backwater feudal world that was terrorized by a being only known as "The Vicious" or "The Foul". After slaying the beast, the Chapter erected their fortress-monastery at Badon Hill and took the task of defending Bristol and the surrounding worlds. The Chapter has grown a mixed reputation, with their feigned retreat tactics perceived as dishonorable by some chapters with whom they have fought alongside. Despite this, the Braves and Bolds are proud members of the Round Table, an alliance of five Space Marine Chapters and some Imperial Knight Houses. Together, the Round Table has been assigned with the important quest of seeking an ancient relic - to make them an example in these dark times.
Brazen Bulls		The Brazen Bulls were a 21^st 'Cursed' Founding, Codex-compliant chapter founded right before the Age of Apostasy from the lineage of the merciless and unforgiving Iron Hands. Originally meant to patrol an area of space north of the Eye of Terror, the Bulls arrived along with another Cursed Founding chapter, the Fell Hands. The two fleet-based chapters cut down on raiding activity in the region for centuries, even managing to skirmish with forces on the edge of the Eye of Terror itself. However, even the resources of two Astartes chapters were spread thin in several sectors, and with the Age of Apostasy in full force the Fell Hands and Brazen Bulls were largely left on their own. After the Fell Hands eventually turned renegade, the Brazen Bulls fought against their former allies and battle-brothers, eventually scattering them into the Eye of Terror at the cost of their own chapter.
Brazen Lions		The Brazen Lions are a Loyalist Codex-divergent Space Marine Chapter created sometime between late-M35 and early-M36 during the mysterious 13^th 'Dark' Founding from unknown genetic lineage. Since their inception, this Chapter has earned the respect of their fellow Adeptus Astartes and the Imperium at large, through their acts of courage, valour, battle-prowess and centuries of loyal service in the Emperor's name. However, there once was a time not long ago that the Lions' loyalty was called into question, for it is to the Chapter's eternal shame that they are successors of the formerly loyalist Astral Claws - a Chapter's whose name that is vilified within the Imperium, and is synonymous with infamy and treachery.
Broken Wings		The Broken Wings were a semi Codex-compliant Chapter descended from the lineage of the heroic Blood Angels. They were an ancient and venerable Chapter who has valiantly served the Emperor of Mankind throughout the existence of the Imperium. Although officially their Founding is Unknown, they were already an existing Chapter of the old IX Legion at the time of the Great Crusade and Horus Heresy eras. Beset by grief and blaming themselves for not being present during the Siege of Terra to prevent the death of their beloved Primarch, the the mournful Chapter struck out into the stars so that they could avenge Sanguinius and "heal their wings". Alas, after millennia of faithful service, the Broken Wings fell on Baal Secundus where they sacrificed themselves to bring down a vast number of a massive Tyranid swarm of Hive Fleet Leviathan in 999.M41. To all who know of the Broken Wings' sacrifice, they regard it as the Chapter's redemption come at last.
Bronze Guardians		The Bronze Guardians is a Codex-compliant, loyalist Space Marine Chapter with an unclear founding as it was created mysteriously in an effort to protect the Sanctus sector. It is rumoured that the Red Crusaders have a part in their founding but there are no imperial records of this. The planet Kevillon, in particular, is a frequent target for xenos invasion which is why it was chosen as their homeworld. The creation of the Bronze Guardians is a mystery to most of the Imperium but the founding members know exactly how they came to be. The goal of the Bronze Guardians is to prove their loyalty to the Imperium by protecting the sector from xenos Invasion. After a large scale war, rumoured to be the Stygian Civil War, their numbers dropped to a mere 200 Space Marines. A large recruitment campaign has taken place to restore their numbers. They have spoken an oath of loyalty to the Imperium and the Red Crusaders and are quite zealous in their worship of the Emperor. They are a silent chapter. They will chant and pray in unison but seldom speak.
Brotherhood of Embers		The Brotherhood of Embers are a Loyalist Space Marine Chapter that is a suspected descendant of the Salamanders Chapter, with their founding being held during the 3^rd Founding. The Brotherhood of Embers is generally concerned with the promulgation of the Imperial Cult and the preservation of what the Emperor sought to create, an empire of humanity across the stars. The Brotherhood achieves this through policing actions across the Segmentum Pacificus. When in combat, the Brotherhood puts the preservation of civilian life before all else. They see it as an important virtue to protect the lives of the Emperor of Mankind's most faithful subjects whenever and wherever possible, in order to replant the planet's society after a campaign has concluded.
Brotherhood of Shadows		The Brotherhood of Shadows are a particularly infamous and darkly-famed Space Marine Chapter created during an Unknown Founding and from uncertain lineage. Their infamous reputation for the amount of violence they inflict upon their enemies is horrific, if exceptional. It is unknown when they were created, but extant Imperial records indicate that this mysterious Chapter first appeared sometime during mid-M35, during the tumultuous era of the Nova Terra Interregnum. The Astartes of the Brotherhood of Shadow are more vengeful executioners than noble warriors, walking a fine line between necessary evil and unchained horror. Since they first appeared, this ruthless Chapter has garnered a fell reputation for their merciless and brutal methods and are rightly feared by both their enemies and allies alike.
Brotherhood of the Midnight Sun		The Brotherhood of the Midnight Sun are a loyalist Space Marine Chapter that was formed around the ill-fated 21^st Founding, the so-called 'Cursed Founding', on the feral jungle planet of Xibalba. Though they claim lineage from the Blood Angels and the noble Primarch Sanguinius, their gene-seed has been tainted by the touch of the murderous Night Lords though the Chapter vehemently denies this. On their dangerous jungle home, the Brotherhood of the Midnight Sun continue to improve their ambush tactics believing that swift unexpected strikes can end conflicts quickly before they can get out of control. In truth, this method is to prevent their brutal and sadistic traits of their genetic forebearers from surfacing.
Brotherhood of the Sword		The Brotherhood of the Sword is a Loyalist Space Marine Chapter descended from the Primarch Rogal Dorn and successors to the honorable and proud Imperial Fists. This stoic and honor-bound Chapter have taken the duty to oversee the border between the Pelegron Cluster and the eternal darkness beyond. As a fleet-based Chapter, they constantly patrol and erasure hostile xenos forces, cleansing of all planets tainted by them. The brotherhood is known for their proud chivalrous culture, assertive mindset and military prowess.
Bullfrogs		The Bullfrogs are a Space Marine Chapter succeeding from the Salamanders created during the ill-fortuned 21^st 'Cursed' Founding. They were founded in order to support the Imperial forces in the Celestonic Sector. However, the Chapter soon found themselves afflicted with a mutation due to bungling ministrations of their Magos Biologis creators. This mutation, called the 'Toadbane's Curse', afflicts the Betcher's Gland organ, causing it to overproduce poison that secrete toxins over the Astrates' skin, creating a film of acidic mucous, that is lethal to the touch. Another unfortunate side-effect of this mutation is that these Astartes practically reek of death and decay, which has greatly affected their reputation, causing the local Imperial populace to distrust and avoid them.
Bulls of Retribution		The Bulls of Retribution are a Loyalist Successor Chapter descended from the lineage of the stoic and proud Imperial Fists, raised in the early decades of M38, during an Unknown Founding. This Chapter was created to stand sentinel over the vitally important Gudan Sector, located in the Ultima Segmentum, from the various enemies of Mankind. As a fleet-based Chapter, they constantly patrol their assigned region of the galaxy, ever-vigilant against the threats of invasion by the various xenos within the region or the vile Forces of Chaos. Their primary recruitment world is the world of Gudan Prime. The Chapter maintains a massive Chapter Keep, built atop the tallest spire of Hive Vaxilian. It is here, that the Bulls maintain their Chapter's vitally important gene-seed banks, reliquary and recruitment and training facilities.
Burning Fate		The Burning Fate are an Ultima Founding Successor Chapter of the vaunted Blood Angels comprised entirely of newly revealed Primaris Space Marines. This chapter, like some of their fellow successors, have garnered an infamous reputation across the Segmentum Tempestus due to their extensive use of fire weaponry and brutality on the battlefield.

Cadian Wall		The Cadian Wall are an Imperial Fists Successor Chapter formed during the Ultima Founding at the behest of Rouboute Guilliman so that they may take part in the Indomitus Crusade. As steadfast and as hardy as their namesake, the Cadian Wall Chapter are true sons of Dorn.
Castigated		The Castigated are a Loyalist Space Marine Chapter that was created from the gene-stock of Primarch Corvus Corax during the recent Ultima Founding. This grim and bellicose Chapter has garnered a dark reputation as retributors of the Emperor, concerned only with bringing swift and merciless retribution to those who dare defy the Master of Mankind's will.
Castigators		The Castigators are a rare Successor Chapter of the Black Consuls Chapter. Created during the 14^th Founding sometime between 975-991.M31, the Castigators have earned a reputation as staunch and stalwart guardians of the Imperium in the millennia since their inception. The Castigators are a zealous and unforgiving Chapter who has garnered a reputation for their fervent desire to purge the enemies of the Emperor for their transgressions.
Caustic Cherubim		The Caustic Cherubim are a Loyalist Successor Chapter of the noble and venerable Blood Angels. Created during an Unknown Founding, this Chapter has gained some renown for its enjoyment of pure destruction and constant conflicts. Like their precursors, they keep the violent/angelic naming theme.
Caustic Reach		The Caustic Reach are a small Adeptus Astartes Chapter created during the 21^st Founding, the so-called 'Cursed Founding', from existing (presumably Raven Guard) gene-seed which was modified to counteract the high potency of Tyranid poisons and toxins these foul xenos commonly employed. Given the gene-seed the scientists managed to create a genetic resistance to the Tyranid poisons and toxins via unprecedented mutation which causes an overproduction of toxins and poisons within these Astartes bodies, which are then transferred to the Betcher's Glands within their mouths, causing them to 'drool' these poisons uncontrollably. This Chapter currently stands at approximately 350 Astartes, their forces severely depleted at the hands of Hive Fleet Kraken, though their exact numbers remain uncertain.
Celestial Heralds		The Celestial Heralds are a Loyalist Successor Space Marine Chapter created during the 15^th Founding from the proud and noble lineage of the White Scars. The history and character of the Celestial Heralds is inseparable from the Huaguo Sub-Sector they call home and have defended for the past five millennia. The civilian government is run by a group known as the Eunuchs, once able administrators who have now devolved into almost comically nepotistic and corrupt bureaucrats. Compounding the issue, the chapter master of the Celestial Heralds is deeply involved with these Eunuchs and through personal loyalty, political blindness, and a complete loss of touch with the situation in his old age, has allowed his control of the situation to completely deteriorate. Reinforcements and Primaris Space Marine upgrades were sent to the sub-sector as soon as contact was made, but further assistance has since been put on hold. It is as yet unclear whether the Huaguo Sub-Sector should be considered fully loyal, or if measures should be implemented.
Celestial Knights		The Celestial Knights are a fleet-based Chapter of the Adeptus Astartes. The Chapter was created during the Second Founding from an unknown progenitor. They are notable for their adaptive tactics, allowing the Celestial Knights to fight alongside most Imperial forces without incident. Stalwart and Pragmatic the Celestial Knights have stood, fighting the enemies of Man wherever and whenever they decide to strike.
Celestial Seraphs		The Celestial Seraphs are an unusual Successor Chapter of Space Marines born during the events of the 21^st 'Cursed' Founding from the gene-seed of Lion El'Jonson. To many of the scions of the Lion, this chapter of Adeptus Astartes is feared due to the fact that they are unleashed by Supreme Grand Master Azrael whenever word of an Unforgiven chapter falling to the Forces of Chaos reaches his ears. When they are set upon the homeworld or the forces of the fallen chapter, the battle-brothers of the Celestial Seraphs are relentless warriors, as they are bloodthirsty, aggressive, beautiful, terrible, and unstoppable duelists that specialize in close-quarters combat, combined with their penchant of unleashing horrifically destructive weapons of Mass Destruction during their Exterminatus actions on both enemy planets or during battles against chaos using either their starships or their armored vehicles. Due to their presence, it is said that very few Unforgiven chapters have fallen to the clutches of chaos, as to do so openly would immediately invite their wrath down onto them.
Celestial Stars		The Celestial Stars is a Space Marine Successor Chapter known for its adherence to the Codex Astartes. They trace their origins back to the Shield Bearers, a previous Chapter whose members were sent on a hundred-year penitent crusade. Upon completing their penance, these veterans formed the initial command cadre of the Celestial Stars. The exact time of the Chapter's founding remains uncertain. Throughout its history, the Chapter has gained recognition for its courageous deeds and selfless sacrifices among its fellow Chapters. The past experiences have instilled in the Celestial Stars an unwavering determination to atone for the actions of their brethren, which fuels their zealous pursuit of redemption. The support of like-minded chapters has bolstered their resolve as they continue their battle across the vast expanse of the cosmos, confronting both familiar and unfamiliar adversaries.
Cerberus Chapter		The Cerberus Chapter are a loyalist non-Codex compliant Chapter created during the recent Ultima Founding and comprised entirely of newly revealed Primaris Space Marines - the stage of evolution of the Adeptus Astartes. Primarily fleet-based, this aloof and mysterious Chapter keeps to themselves, preferring to wage their own private war against the enemies of Mankind. Rarely, does this Chapter fight alongside other forces of the Imperium, and on the rare occasions that they do, they prefer to keep their own counsel and wage their campaigns as they see fit, only reporting to Imperial command to inform them of their progress.
Cerulean Hounds		The Cerulean Hounds are a loyalist Space Marine Chapter, created during the 26^th Founding. Due to their near extinction during the Devastation of Baal, the chapter is home to many Primaris Space Marines. Formerly based from a fleet circling the Baal System, the chapter now calls the Feral World of Savis its home. Even if the Cerulean Hounds are settled on a world, they still possess a mighty fleet and thus combat threats all over the Imperium of Man and outside of the known galaxy. To go beyond and get combat the unknown threats of the far fringes of the galaxy is their purpose. The marines of the Cerulean Hounds chapter are experts in fighting all types of xenos but especially; Drukhari, Tyranids and Orks, in brutal close combat.
Chalice Heralds		The Chalice Heralds are a Loyalist Successor Chapter of the proud and valiant Blood Angels created during Unknown Founding. Most of their history has been lost and their own records are either incomplete or destroyed. Because of this they guard their history and only tell those they trust, their origins. Despite their laudable history and numerous battle honours, there yet remains a shadow of the Blood Angels' genetic flaw that lingers ever about the Chalice Heralds. With a history of heroism and valour as laudable as some more venerable Chapters, it is easy to see why they are heralded far and wide across the Imperium as exemplars of the Great Angels' lineage. They have vanquished foes far and wide from Orks to Chaos Space Marines, and always upheld the honour of their Chapter, and founding Legion.
Chameleons		The Chameleons are a loyalist Successor Chapter of the mighty Salamanders, brought into the fold with the advent of the 4^th Founding following the near-disastrous conflict known as the War of the Beast during the middle centuries of M32. Reknowned for their stealth based tactics the chapter has hunted for the sons of the traitor legions since the chapter's inception. The chapter shares a deep paternal affection for humanity with the parent chapter, often forgoing their exemplary covert stratagems for the sake of civilians or guardsmen.
Champions of Mortis		The Champions of Mortis are an ancient, semi-Codex compliant Successor Chapter of Adeptus Astartes created during the 3^rd Founding from an unknown sire. This Chapter is currently located in the southern fringe of the Imperium of Man, and they have devoted themselves to fanatically target and purge Heretic Astartes emerging from the Scourge Stars, especially those of the hated Death Guard Traitor Legion.
Chancellors of Genesis		The Chancellors of Genesis are a nominally Loyalist semi-Codex-compliant Chapter created from unknown lineage during an Unknown Founding. They are an old and secretive Chapter. Not much is known about its background and the High Lords of Terra keep the purpose and lineage of the Chapter a well-kept secret.
Charybdis Astra		The Charybdis Astra is a Loyalist non-Codex compliant Chapter of the Adeptus Astartes that hailed from the oceanic death world of Moturoa. There are no records of the chapter's founding date nor the chapter's successors due to the chapter's recent disastrous events known as Moturoa's Deluge that destroyed the chapter's former Fortress-Monastery. The Chapter was created to support the Herzavar Sector against both the Forces of Chaos from the Maelstorm warp rift and to counter raiding xenos forces. The chapter is known for its deadly close combat specialists, master infiltrations, sabotage and assassination of high value targets as well as its possession of Sibranite Alloy Blade, a combat knife made from ancient alloy native to Moturoa that could disrupt warp entities, shield generators, or any radio frequencies.
Children of Seth		Named after the bloody-handed lord of the Flesh Tearers from whom they are descended, the Children of Seth are a Chapter infamous for the murderously violent and destructive manner by which their wars are waged. Created during the 23^rd 'Sentinel' Founding, this Chapter hails from the harsh desert world of Atum. Since their inception, the Children of Seth have carved themselves deep into the annals of Imperial history, each page dripping with the blood of their foes.
Chiroptera Legion		The Chiroptera Legion are a mysterious and enigmatic Loyalist Adeptus Astartes Chapter created during an Unknown Founding and from uncertain descent, but it is believed to early. Imperial scholars speculate this Chapter to have possibly been created as early as the 2^nd Founding, following the end of Great Scouring in 021.M31. They are inhuman monsters, vicious and violent beyond what is expected even of Astartes, their armour covered in macabre images of death and terror. These vicious Astartes have even been compared to the murderous Night Lords Traitor Legion, and the similarities between them have led many to claim that it is more than just coincidence, for unlike other Chapters that bring hope to worlds, the Chiroptera Legion does not come to liberate, they do not come to save - they come to bring judgement and to punish.
Chogorian Outriders		The Chogorian Outriders are an Ultima Founding Successor Chapter of the elusive White Scars, comprised entirely of newly revealed Primaris Space Marines. The Chogorian Outriders Chapter was founded in response to the creation of the Great Rift in 999.M41, serving within the legions of the Unnumbered Sons.
Cicatrix Blades		The Cicatrix Blades are a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created from the lineage of Jaghatai Khan, raised during the Ultima Founding in 999.M41. The Cicatrix Blades originally consisted of 3 full companies of White Scars Greyshields Primaris Space Marines, raised after the Indomitus Crusades' initial phase. The Chapter's homeworld is a penal world called Ixaos Fall, established as the chapter's homeworld after the recruitment potential of the local planetary populace was realised during the Dunrolium Wars.
Claws of Arktos		The Claws of Arktos are a Loyalist Space Marine Chapter created from the ferocious Bears of the Claw. These bellicose and fierce Astartes were created during the 23^rd Founding, the so-called 'Sentinel' Founding, as a part of a series of linked Foundings that took place during the latter part of M37, to help replace the considerable losses suffered by the Adeptus Astartes in the preceding millennia. Along with several other Chapters, the Claws of Arktos were from the outset, conceived as a replacement Chapter that would spend its existence on continuous Crusade. The newly created Chapter was one of several Chapters tasked to take and hold the Aliris Sector, located to the galactic south of Cadia in a star rich part of the Segmentum Obscurus. Claiming the isolated death world of Arktos as their own, the Chapter garrisons the planet from above in their ancient star fortress Ferus Unguis. Taking their name from the deadly world, the 'Claws of Arktos' Chapter began their endless Crusade, to bring their unfettered wrath down upon those vile xenos races that would dare assail the Emperor's domain.
Cobalt Consuls		The Cobalt Consuls are a Loyalist Ultima Founding Successor Chapter of the Black Consuls, whom themselves descend from the lineage of the vaunted Ultramarines. They are based upon the fortress world of Castellum in the Macharia Sector of the Segmentum Pacificus. They specialize in decapitation strikes, locating the head of whatever snake they face and ruthlessly cutting it off with overwhelming force.
Cobalt Crusaders		The Cobalt Crusaders are a Loyalist Space Marine Chapter of the Adeptus Astartes created during the 7^th Founding somewhere between M33 and M34. Created as a means of assembling a chapter with the cold nature of the Iron Hands and the stalwart dedication of the Dark Angels, the Cobalt Crusaders have proven themselves time and time again as the epitome of space marine efficency, their loyalty unwavering and their pursuit for strength never-ceasing.
Cobalt Leviathans		The Cobalt Leviathans are a Loyalist Space Marines Chapter founded during the 23^rd 'Sentinel' Founding in M38 from the gene-seed of the fierce White Scars. The Cobalt Leviathans are known for their nomadic nature and brutally swift method of combat, not unlike their progenitor Chapter. The Tribes (Companies) of the Cobalt Leviathans are always on the move, choosing instead to have their home world defended only by the Ocean Guard, Auna (serfs) and Togi (Neophytes) of the Chapter. Lead by a lone Vasa Ngaru, bearing the title of Lord of the Triumphrat, they are entrusted with the greatest responsibility and the hardest burden, to defend their hearth and home the fortress-monastery Pakari. That is not to say that the Tribes of the Cobalt Leviathans do not return home, for at the end of every campaign they return to tell their deeds through ritual chant preserving the oral tradition of the Chapter and of the homeworlds.
Cold Blooded		The Cold Blooded are a Loyalist Space Marine Chapter of the bloodline of Sanguinius, supposedly created during the mysterious 13^th Founding, the so-called 'Dark Founding', which occurred sometime between M35 and M36. Like their predecessors, they stand aloof from the rest of the scions of Sanguinius and even from the Chapter from which they were spawned.
The Condemned		The Condemned are an ancient and venerable Chapter supposedly created during the Second Founding as a rare Successor Chapter of the Raven Guard following the end of the Horus Heresy and subsequent Great Scouring. In an effort to make better use of incorrigible youth whom were often toughened, resilient children, a progressive amongst the High Lords of Terra decreed that he would demonstrate that enforcing the Pax Imperialis could provide an even greater benefit to the Imperium. He did this by creating a specialist Chapter with recruits drawn from the Imperium's criminal youth. Named the Condemned, this newly formed Chapter was expected by many not to last a single generation, however, this chapter of child thieves, gangers and murderers has instead prevailed through the annals of time in obscurity and against adversity, proving that reformation and redemption can be found in service of the Emperor in glorious battle and, ultimately, in death.
Condemners		The Condemners are a Loyalist Space marine Chapter founded during the 23^rd 'Sentinel' Founding in M38. Their gene-seed origin and progenitor Primarch are both shrouded in mystery. However, they have always served the Emperor with unwavering loyalty and fierce dedication. The Condemners are often deployed to quell Chaos and xenos uprisings, displaying ruthless efficiency in their task. They show no mercy to the enemies of mankind, condemning them to utter annihilation. Their campaigns have left countless worlds in ruin, but they have also saved countless more from falling into the clutches of darkness. The Chapter's warriors are known for their steadfast resilience and ruthless tactics. The Condemners, above all, believe in the implacable judgement of the Emperor. They see themselves as the divine adjudicators of His will, tasked with the merciless eradication of any and all threats to the Imperium. They are known for their uncompromising pursuit of justice, often preferring to completely exterminate populations that have been tainted by Chaos or Xenos influence rather than attempt to reclaim them.
Conquistadors		The Conquistadors (translated to High-Gothic as Conquerors) are a Successor Chapter created as a 23^rd 'Sentinel' Founding of the Imperial Fists. While it is confirmed that their Primarch is indeed Rogal Dorn, it cannot be confirmed which Chapter they are descended from, with any certainty, however, many scholars believe they are descended from the Black Templars. The Conquistadors are a Chapter created with great ambition, intended to be a rapid-acting shock force and at the same time an exploratory colonizing force. Their primary goals are to give a rapid and forceful response to the conflicts that arise in the Segmentum Pacificus and to expand the borders of the empire by exploring and conquering new worlds in the name of the Emperor.
Corpse Wolves		The Corpse Wolves are an Ultima Founding Successor Chapter created from the proud lineage of the feral Space Wolves. The Corpse Wolves were one of several new Successor Chapters comprised entirely of Primaris Marines, created to help defend the Imperium of Man from the various enemies of Mankind, that currently assailed the Emperor's realm on all sides. They helped turn the tide in the notable Imperial campaign which came to be known as 'The War for Polaris's Star'. Located at the tip of the border between the newly designated Imperium Nihilus, or the 'Dark Imperium', which had gone dark without the beacon of the Astronomican, and the light Imperium.
Corrosive Thorns		The Corrosive Thorns are a 21^st 'Cursed' Founding Chapter from the stock of the brave and stoic Iron Hands. This particular Chapter unlike its brethren have a low affinity for the Mechanicus rather being away from them as much as possible. Like many 21^st Founding Chapters the Corrosive Thorns have a mutation in the Betcher's Gland that mutated into the pores of the skin leading to the sweat of the Astartes being heavily corrosive. Their combat speciality of the Chapter is Frontal Assault and Astarte Suppression especially towards other Iron Hands Successors.
Corvus Brethren		A dark, sinister Chapter, the Corvus Brethren are a bellicose and violent Chapter. Born during the 21^st 'Cursed' Founding, the ill-fortune of their birth follows them like an evil shroud. Few know them and few trust them. Whilst officially they come from the lineage of Corvus Corax, tensions between the two regarding the Brethren's brutality have called this into question, especially given the warriors of Badb Catha's blatant disrespect for their supposed progenitors. Endlessly blighted by in both gene-seed and luck, the Corvus Brethren are a coldly resolute force. Enduring the endless predations of the Drukari and leaving a bloody path littered with the countless foes of the Imperium.
Corvus Claws	Pict-File Unavailable	The Corvus Claws are a sneaky and deadly Loyalist Successor Chapter descended from the lineage of Corvus Corax lineage. Create during the 23^rd 'Sentinel' Founding, this Chapter has become famed for jumping out of their aerial vehicles, mid-battle. They also specialise in covert missions and infiltrations. Another thing they are famed for, is their sense of humour. This makes them popular with some Chapter, others on the other hand find it annoying. Their most famous tactic is jumping out of a plane mid-flight. In this way they can surprise their enemy from above. They work in Kill-Teams and use the element of surprise. Even though they're a fleet-based Chapter they have a home world. It is there where they get their new recruits. Their Raven King resides on this planet, called Glavius. The fleets of the Claws travels around Galaxy. These Space Marines are deployed when Kill-Teams are needed.
Costa Veraian's Might		The Costa Veraian's Might are a loyalist Space Marine Chapter of the 23^rd 'Sentinel' Founding as a Successor Chapter of the heroic Ultramarines. The chapter was founded originally as a mix of Crusading Force and Counter-Force in the Segmentum Obscurus where the traitorous brothers have fallen in hopes of slaying them and purging their heresy but the purpose has slowly shifted over the many years into a permanent standing force. These Astartes are known to be loyal to their bitter end and have a hate for the vile sinners and heretics seeming no different than others in a way that makes them seem almost overgrown criminal hunters. But despite this, they tend to have a more welcoming attitude towards fellow Astartes and even to those such as the citizens of Savlar. Aside from this, they are quite adaptable to any tactical situation and are not picky in terms of how to kill a foe.
The Creed		The Creed was once a noble Chapter descended from the lineage of the proud and heroic Ultramarines. Created during the 23^rd Founding, the so-called 'Sentinel Founding', the newly incepted Chapter was assigned the Imperial planet of Creed as their new Chapter homeworld. They quickly established a reputation for the use of formidable heavy artillery and devastating bombardments. The people of Creed had a disdain for this new rule, and so Creed descended into anarchy and full-blown insurrection. Only with the assistance of a local Imperial Knight House was the Chapter able to quench the rebellious populace, however, they suffered the loss of half their number during the conflict. Feel unworthy to lead his Chapter, The Creed's Chapter Master stepped down from the command of his surviving battle-brothers, and passed on leadership to a young and ambitious Astartes. This newly instilled Chapter Master immediately launched a campaign of conquest across the stars. Seceding from the Imperium, The Creed struck out on their own determined to forge their own path. However, after nearly a millennium of constant warfare, the Chapter had little to show for their efforts. During the waning years of M41, The Creed was finally considered a threat to the Imperium and was forever deemed Traitoris Perdita by the High Lords of Terra. (Traitoris Perdita)
Crimson Blades		The Crimson Blades are Loyalist Successor Chapter of the mysterious Raven Guard, created during the most recent Ultima Founding. Originally known as the Blades of Corax, the newly incepted Chapter was deployed as a part of the Imperial Indomitus Crusade in the wake of the tragic events of the 13^th Black Crusade and the Fall of Cadia. Following their inception, the newly created Chapter nearly faced ultimate tragedy, when they discovered their newly assigned home world had become enthralled by the corrupting influence of the Ruinous Powers. Despite being massively outnumbered, the Astartes of the Blades of Corax stoically faced the heretic masses in a deadly siege. Emerging bloody but victorious, despite their extensive losses the Blades of Corax refused to be deterred. When the few survivors emerged from the ashes of their home world their battle-plate and weapons were so covered in the blood of the fallen, that they henceforth referred to themselves as the Crimson Blades.
Crimson Dragons		The Crimson Dragons are a Loyalist Chapter created during the ill-fated ^{21^st} 'Cursed' Founding. They are a Successor Chapter of the noble and angelic Blood Angels. Due to the meddling of the gene-wrights of the Adeptus Mechanicus, this Chapter, like most chapters from its founding, has a long history of being plagued with rampant mutation and genetic idiosyncrasies. Being a part of the Sanguinary Brotherhood, they harbor the twin curses, the Black Rage and the Red Thirst. Apart from this, other dragonlike mutations have emerged, notably large, draconic wings. The Inquisition constantly monitors the chapter because of its mutation. There have been reports of some Chapters (namely the Dark Angels and the Marines Malevolent) refusing to fight beside the Crimson Dragons.
Crimson Dragoons		The Crimson Dragoons are a Loyalist Successor Chapter created during the 25^th 'Bastion' Founding directly from the lineage of the zealous and fierce Black Templars Chapter, who themselves are descended directly from the proud and stoic Imperial Fists. Their capabilities with all forms of ranged weaponry can only be matched by their faith in the God-Emperor. Shielded by faith and armed with zeal, they strike down anyone who would dare oppose the Holiness of the one true ruler of Mankind.
Crimson Hounds	Pict-File Unavailable	Possessing all the hallmarks of a 23^rd 'Sentinel' Founding Chapter, the Crimson Hounds are known to be restless and possess a strong crusader's zeal. The Founding is filled with Crusade Chapters that plunged into the battlefields of the far future almost as soon as they were created, and never stopped fighting; the Crimson Hounds know this all but too well. Ever since their Founding, the Crimson Hounds have had a reputation as being stoic while absolutely savage in their techniques as a Space Marine Chapter - one that throws itself into battle without hesitation and emerges victorious in spite of overwhelming odds. They seem to be steadfast in a stoic manner; then utilize a fast attack technique with savage hand-to-hand combat.
Crimson Owls		The Crimson Owls were created during the ill-fated 21^st 'Cursed' Founding in an attempt by the Adeptus Mechanicus to fabricate an especially psychically apt chapter. To do so, they used the already psychically inclined gene-seed of The Angel, but that proved to be a great mistake, since while they achieved their objective of creating a chapter with a great amount of librarians, the Flaws affected its members in even deeper ways than other successors of Sanguinius. Even with such flagrant taint the Crimson Owls escaped the fate that gobbled so many other chapters of the Cursed Founding by being extremely strict, and executing all the battle-brothers who fall into the Red Thirst or the Black Rage. Thanks to these drastic measures, they manage to stay on the good side of the High Lords of Terra and the Inquisition, avoiding the risk of beeing disposed of and warding themselves of close investigations that could bring to light dangerous secrets.
Crimson Prowlers		The Crimson Prowlers are Successor Chapter that hails from the lineage of the mighty and powerful Space Wolves, created during the recent Ultima Founding in 999.M41. They were created as one of the first of many Successors, a whole line of descendant Fenrisian Chapters - the 'Sons of Russ' - capable of carving out a star empire the size of Ultramar. This was the vision: to be powerful enough to encircle the Eye of Terror completely, to prevent the Traitor Legions from daring to leave it ever again. The Crimson Prowlers, along with several other Primaris Successor Chapters, were created to help protect the Imperial sectors surrounding the Eye, and supporting Imperial worlds and the Inquisition as needed.
Crimson Robes		The Crimson Robes were a Loyalist Successor Chapter of the stoic Imperial Fists, raised at the beginning of M32 during the 3^rd Founding. Highly regarded for their siege capabilities and the arbiters of a number of impressive victories, this promising young Chapter was seemingly wiped out just over a millennia after its inception, but later returned to the Imperial fold, temporarily, nearly three millennia later. However, the Chapter's bad luck continued to dog them, as they had the misfortune to cross paths with a massive Ork WAAAGH!, only to be utterly annihilated.
Crimson Sentinels		The Crimson Sentinels are an ancient and laudable Successor Chapter that believes themselves to have been created during the 2^nd Founding shortly after the events of the Horus Heresy from the lineage of the noble Blood Angels. However, they do not appear in the list of Second Founding Chapters found in the Apocrypha of Skaros, the oldest-known surviving copy of the Codex Astartes, the veracity of their claim throws into question whether or not this Chapter is as ancient as they claim to be. Like all Successor Chapters created from gene-stock of the angelic Primarch Sanguinius, the Crimson Sentinels are also greatly affected by the effects of the twin genetic-curses of the Blood Angels' inherited Flaw. Although, unlike most of their fellow Chapters of the Host, they are more affected by the vampiric craving for blood, known as the Red Thirst, than they are by the ravages of the Black Rage. The Crimson Sentinels are known to suffer from this second flaw at a much-reduced rate compared to the Blood Angels or their other Successor Chapters. The reason for this is unknown, however, many of their detractors whisper that perhaps the Chapter has bought this boon through malefic means.
Crimson Seraphim		The Crimson Seraphim is a 2^nd Founding Blood Angels successor with a specific vendetta against chaos space marines. They believe not that the traitors must be culled, but that they have been swindled by the lies of the ruinous powers and in death, they are redeemed. Their chapter master and Master of Sanctity were thrown forward in time by a warp storm, and exist only to reclaim the lost honor of 10,000 years.
Crimson Vanguard		The Crimson Vanguard are a Loyalist Chapter that was created in the Ultima Founding as one of the Successor Chapters of the White Scars. Early in the chapter's history, the Chapter found records that were written by the Ancient Terran samurai and in order to pay homage to these warriors, the Crimson Vanguard decided to adopt their culture.
Crimson Wardens		The Crimson Wardens are a 7^th Founding Successor Chapter of the Blood Angels. Inspired by their homeworld Anthas II, their culture is very knightly, and they value strength of will above all else. After being nearly wiped out by a Necron awakening, they were reinforced by the remains of a shattered Black Templars successor chapter, whose name is lost to the ages. This further influenced the Crimson Warden's culture to change their values to that of the Black Templars, though they aren't as religious.
Crow Stalkers		The Crow Stalkers are a Raven Guard Successor Chapter founded during the 8^th Founding, which allegedly occurred during mid-M34. This Founding was undertaken amid the dark times of the Nova Terra Interregnum, when the Imperium of Man had been split into two separate interstellar empires. The Crow Stalkers were one of several such bellicose and ruthless Chapters created at the behest of the High Lords of Terra, to strike fear into the Imperial populace and scare them into compliance during these tumultuous era. The few extant records that exist indicates that this ferocious Chapter wreaked terrible slaughter on those who opposed Imperial rule, and due to their bellicose and merciless nature, developed a savage culture as a result.
Crusaders Inexorable		Founded during the 8^th Founding, the Crusaders Inexorable have over the millennia gained a reputation for being inexhaustible, never ceasing in their hunt against the enemies of The Imperium. They have proven in the past to be rather isolationist when it comes to their fighting, often refusing aid, and always opting to fight on their own rather than trust any other force when possible. Originally as a chapter, their propensity for fighting alone was likely through some strange form of pride or repentance, perhaps for their first Chapter Master's failure in their first independent battle, but over time this disposition has been strengthened by repeated betrayals from close allies.
Crux Catharian		The Crux Catharian is a semi Codex-compliant Successor Chapter created during the 24^th Founding as a successor of the Iron Talons of the Astartes Praeses, whom themselves hail from the ancient and heroic lineage of Jaghatai Khan. Like their progenitors, the Crux Catharian share their general recklessness and tendency to extend their operations. However, they will readily fight alongside other Imperial forces, but remain aloof and unforthcoming with other Imperial commanders, preferring to maintain their own counsel and values in achieving their tactical objectives. This uncharacteristic respect for their brothers in arms is especially noteworthy as the Crux Catharian chapter will often remain on worlds long after they are liberated to hunt down stragglers, Orkoid spores, and whatever is necessary to truly ensure that their fellow man can live in relative peace. However, as benevolent as they might act, their true, intended purpose remains - to cleanse worlds of the taint of Chaos long after the battle is seemingly won, a purpose that the chapter follows to an often alarming extent.
Crypt Keepers		The Crypt Keepers are a mysterious and aloof Space Marine Chapter created from an uncertain lineage that emerged from the dire events surrounding the cursed planet of Agros-VII in the Calixis Sector. Founded in secrecy and driven by the desperate need to overcome the insidious cannibal curse plaguing their ranks, they bear the weight of a forbidden alliance with xenos technology. The Crypt Keepers hold a complex set of beliefs shaped by their experiences on Agros-VII and the curse that plagues them. Their beliefs revolve around their visions, the goddess Ishnet, and the insidious cults that lurk within their chapter's history.
Crystal Dragons		The Crystal Dragons are a Loyalist Space Marine Chapter of the Adeptus Astartes created during the 25^th 'Bastion' Founding, specifically for the purpose of supervising other chapters' penitent crusades. The Iron Hands lineage was chosen for their strong adherence to logical thought and reason over passion and feelings. In their short story, the Crystal Dragons have already accompanied over 20 of such crusades, treating those under their surveillance with cordiality yet cold severity to make sure that those Astartes atone for their past sins against the trust of the Emperor.
Crystal Lions		The Crystal Lions are a Loyalist Successor Chapter created during the 22^nd Founding from the Angels of Absolution who themselves hail from the lineage of the ancient and secretive First Founding Dark Angels. Over several millennia the Chapter has perfected the use of combined arms and multi-spectra warfare. A favoured tactic of the Crystal Lions when beginning a planetary strike is to launch a devastating orbital bombardment upon the enemy's position. Following this initial strike, the Chapter then utilises drop pods and Thunderhawk gunships in strategic decapitation strikes against high-value enemy targets to disrupt their foe's command and control. This is followed by an all-out assault comprised of Dreadnoughts and various patterns of Rhino armoured personnel carriers, as well as heavy support from Land Raider Ares to safely insert their battle-brothers into enemy strongholds to close with the enemy in bloody melee combat.
Crystal Skulls		The Crystal Skulls were created to prevent a terrible prediction created by many psykers on tarot cards. They said that in the near-future humanity would again be under threat of destruction from the mandibles and jaws of an uninvited guest from outside our galaxy, who was nicknamed as the Great Devourer. The horrors of the first war with Tyranids left a deep scar on the body of both the Imperium and the entire Milky Way galaxy. Panic among the servants of the Inquisition and the Administratum can lead to another discord of humanity, and in order to prevent such an outcome, the decision of this outcome was made, the Lords of Terra decided to establish many Astartes chapters to fight the all-devouring horror of the outer void, as well as a huge number of additional units of mortal armies. As it was said, the Crystal Skulls were created by one of these chapters. They settled on the dead world of Zabveniye, on whose surface there was no vegetation or multicellular life forms. And the human settlement lived in underground settlements near the remaining water mines, surviving solely on food supplies. However, now this world is completely under the control of the chapter, from which supplies have become much more, and also, for a better selection among the mortal population, such deadly xenos as ambulls, vampires and a huge variety of others have been released into the caves. And let the danger to human life on that world has greatly increased, but it has erected a cult of hunting, perfectionism and a human temple, and the population of these xenos is tightly controlled by the forces of the PDF and the chapter's auxilia.
Cyclopean Sons		The Cyclopean Sons are an Astartes Chapter of unknown founding and descent. Little known to the greater Imperium this elusive and enigmatic Chapter has always been drawn to the pursuit of knowledge and the acquisition of ancient lore. It produces an unusually large number of Librarians among its ranks as a high proportion of Neophytes develop psychic abilities soon after their implantation with the Sons' gene-seed organs. Their powerful Librarians guide the Chapter, enabling them to fight with precision and calculated fury made possible by their ability to predict and thwart their enemy's strategies and tactics before they come to pass. These arcane powers have led to great speculation and some concern about the true nature and origins of this Chapter in the rest of the Imperium of Man, but as of yet no formal investigation has commenced and with the return of the Primarch Guilliman and the need for loyal Chapters more acute than ever before, it is likely that it never will.

Dakkamarines		The Dakkamarines is a presumed Renegade Space Marine Chapter of unknown founding, officially regarded by the Imperium of Man as an urban legend. The cause of this may be in the nature of the chapter itself, as it is composed—if true— entirely by Diggas, which are humans that have adopted the culture of the Ork race. (Traitoris Perdita)
Dark Crusaders		The Dark Crusaders are a loyalist Space Marine Chapter created during the 21st Founding, the so-called "Cursed" Founding, from unknown genetic heritage. Like many other chapters created during this founding, suffer from a genetic abnormality within their gene-seed. Rumoured to have been born from attempts to create marines that would never tire, the Dark Crusaders possess a hyperactive Catalepsean Node - the sixth implant a Space Marine receives during the Rites of Initiation that aids a marine with sleep deprivation by resting individual parts of the brain. This abnormality with their Catalepsean Node causes the Dark Crusaders to be in a constant waking state, unable to ever sleep or enter a state of forced state of suspended animation, including any attempts at utilising the Sus-an Membrane. Due to this genetic flaw, Astartes from the Dark Crusades are eventually affected by an affliction known as the Twilight - a rapid degradation of the marine's brain functions that leads to an incurable coma, becoming nothing more than hollow shells of the beings they once were. (Note: This Chapter falls under the Expanded Universe category.)
Dark Hosts		The Dark Hosts are a Loyalist Successor Chapter of the Dark Angels. Created during an Unknown Founding, they were made up of particularly revanchist members of the Dark Angels Legion who sought to maintain the traditions of the Hexagrammaton and the duty of their Primarch Lion El'Jonson to scour the darkest corners of the galaxy of the most dangerous threats to the Imperium. The Dark Hosts are a calculating and relentless force that has been on crusade across the galaxy since their founding, highly trained and exceptionally equipped for all styles of warfare to meet the challenge of their endless vigil. They wander from campaign to campaign across the stars as a grim reminder to the galaxy of the time when the Dark Angels were the Emperor's Exterminators.
Dawn Guard		The Dawn Guard (sometimes known as the 'Cult of Dionysos') is a Renegade Chaos Chapter of Adeptus Astartes created during the ill-fated 21^st Founding, the so-called 'Cursed Founding'. Unlike many renegade chapters, the Dawn Guard still cling to the precepts of the Codex Astartes and some members still continue worship of the Emperor, despite their renegade status. It is unknown what gene-father the Dawn Guard hail from, however, it is known that a mutation in their gene-seed causes some members to suffer from a nearly insatiable greed. This flaw causes the chapter to make entire ships into "museum barges" that store mass amounts of knowledge, relics, and wildlife. (Traitoris Perdita)
Dawn Guardians		The Dawn Guardians are a semi-Codex compliant Ultima Founding Successor Chapter descended from the proud lineage of the Ultramarines, specialising in liberating worlds lost in the calamity of the Great Rift as well working with the Historitors to reclaim vital knowledge from the most dangerous of warzones; recovering precious archives and destroying heretical texts with fire. Furthermore, they are known for their tendency to act as noble knights; charging into battle with swords raised to earn further glory for their Kingdom and Chapter.
Dawn Lords		The Dawn Lords are a Loyalist Successor Chapter created during an unknown founding from the lineage of Primarch Jaghatai Khan. This Chapter has a short history due to their recent founding by the Imperium's acting Lord Commander. Their Firstborn brothers, on the other hand, have a long battle record extending back to M34. Much of the original Dawn Lords' story has been forgotten, although incomplete records indicate that they are an offshoot of the Destroyers Successor Chapter. What is known is that they were assigned to patrol the northern reaches of the Segmentum Obscurus and were last heard to be operating at full strength prior to the advent of the event known as the Noctis Aeterna. Their subsequent fate is unknown, but the Primaris brothers of the refounding hope to find word of their lost brothers' status. The search will have to wait. Since assuming their duties, the Dawn Lords have endured terrible losses to the rising tide of the alien, the heretic, and darkness within the Imperium Nihilus.
Dawn Stalkers		The Dawn Stalkers are a Chapter created during the 22^nd Founding, a chapter born of the legacy of Rogal Dorn. While they publicly declare themselves as successors of the noble and proud Imperial Fists, they are in actuality sourced from the Crimson Fists, a secret known only to them and chapter father, along with relevant administratum officials. In combat and daily duties, the Dawn Stalkers place emphasis on the ability to withstand the punishment of body and soul alongside the care and protection of the Imperiums mortal population. For these reasons this chapter of Astartes are well versed in attrition-based warfare and rear-echelon/civilian protection duties.
Dawn's Wolves		The Dawn's Wolves are a rare successors of the Space Wolves Chapter, an oddity made possible by the creation of the Primaris Astartes. They have been created extremely recently, coming together as a Chapter only after the end of the Indomitus Crusade, from the ranks of the Unnumbered Sons. Since that time, the errant Chapter has made is best to defend the borders of the Imperium and bring the wrath of Leman Russ upon the enemies of Mankind. This origin explains why they are far less independent and more prone to cooperation with other Space Marines. The Dawn's Wolves make up a part of an unofficial collective comprised of a quadrumvirate of Space Wolves Successors known as the 'Sons of Russ'.
Dead Bells		The Dead Bells Space Marine Chapter are a loyalist semi-Codex compliant Successor Chapter that was created from the lineage of the proud Dark Angels. The Chapter was founded in 831.M33 during the strange period called the Year of Ghosts. Little are know what happened during this event, but there are reports that spectes of honoured dead rose up and defeated an incursion from the Warp.
Death Angels		The Death Angels are a Successor Chapter of the venerable Blood Angels Space Marine Chapter. They were created during the 5^th Founding sometime during the early centuries of M33. These Scions of Sanguinius were created at the express order of the High Lords of Terra in order to counter encroaching Forces of Chaos within the Tenadain Sector. The Death Angels tend to display a violent savage mien in battle, and have garnered a reputation as a bellicose and bloody-handed Chapter. As a Successor Chapter of the Blood Angels, they too, are greatly affected by the twin curses of the Red Thirst and the Black Rage. It is rumoured that they continue to reign down terrible destruction, wrought against friends and foes alike, yet the Death Angels still continue to faithfully serve the Emperor and their Primarch Sanguinius, despite their genetic afflictions.
Death Bearers		The Death Bearers are a Successor Chapter founded, in all probability, from the lineage of the Raven Guard during the 24^th Founding. Calm and disciplined, the Death Bearers unleash the full fury of the Adeptus Astartes once they come into contact with the enemy, but not without first establishing a solid strategy. Equally adept with the sword and the bolter, this chapter relies on adaptability and flexibility during their campaigns. They proudly proclaim their kinship with Corax and his Raven Guard, and make sure to incorporate and adapt the Primarch's precepts into their strategies to honor him.
Death Champions		The Death Champions are loyal Space Marine Chapter hailing from the lineage of the courageous and stoic Iron Hands. They were created during the 4^th Founding sometime in the mid-500s.M32, following the near-disastrous War of the Beast, when the Imperium of Man was nearly decimated by the largest Ork WAAAGH! not seen since the Ullanor Crusade during the latter years of the Great Crusade. Unlike many of their fellow Chapters, they do not follow the wisdom of the Codex Astartes, instead following their own wisdom of warfare. The Death Champions also dsiplay a perculiarly idiosyncratic Chapter cult, whose rites and traditions focus on death and martyrdom. This obsesession with death and macabre began after a chance encounter with the mysterious revenant Astartes known as the Legions of the Damned. Since that time, the Chapter has revered the fallen over and above the living, which is displayed by their use of the symbols of death and mourning in their Chapter iconography.
Death Flowers		The Death Flowers are a Loyalist Successor Chapter of the Black Lotus Chapter which was created during the ill-fated 13^th Founding, the so-called 'Cursed' Founding. The Death Flowers were created mostly of Primaris Space Marines during the recent Ultima Founding, after the original chapter was reduced to only one company. Such massive losses led to the creation of the newly reconstituted chapter. The chapter's predilection for guerrilla warfare and use of stealth tactics has led many Imperial scholars to suspect that they are successors of the Raven Guard Chapter. This Chapter was assigned with searching and destroying Necron tomb worlds.
Death Gladiators		The Death Gladiators, known also as the "Emperor's Executioners" or preferably known as "The Frenzy Killers", are a terrifying and highly esteemed Space Marine chapter originating from the Praetorian of Terra, Rogal Dorn, who is associated with the Imperial Fists. First established during the Ultima Founding, The Death Gladiators stood out as a chapter with remarkable proficiency in the areas of defense, fortification, and brutal close-quarters combat, akin to the capabilities of an Imperial Fists Space Marine. The Death Gladiators' commitment to the Imperium and their unwavering loyalty to the Emperor's cause earned them a respected place within the ranks of the Adeptus Astartes. Their history, capabilities, and unyielding spirit have made them a legendary chapter, and their legacy continues to inspire others in the service of the Imperium. The Death Gladiators, despite their ominous name and the outward appearance of heretic Astartes, have proven themselves to be unwaveringly loyal to the Emperor of Mankind. These enigmatic warriors have garnered a reputation for their fierce dedication to the Imperium and their willingness to do whatever it takes to ensure its survival.
Death Templars		The Death Templars are a Loyalist Space Marine Chapter of the Third Founding that occurred in 021.M31, following the brutal and bloody years of the Great Scouring. An ancient and proud Chapter, the Death Templars are scions of the proud line of Rogal Dorn of the Imperial Fists Chapter. Aside from an unbreakable sense of honour and a history of unparalleled skill at arms, the Death Templars share little in common with their forebears' culture and traditions. Left to operate alone at the edge of the Imperium has bred within them an isolationist and fiercely independent streak that has seldom been embraced by outside command. Over time they have also gained a shadowed reputation for themselves with other Imperial authorities as well as fellow Adeptus Astartes, who view their seemingly unnatural obsession with death and strange mortuary traditions with suspicion.
Deep Angels	Pict-File Unavailable	The Deep Angels are a loyalist Space Marine Chapter whose origins harkens back to M39 on the former hive world of Brine. A detachment of Blood Angels first arrived on Brine in response to a distress call from an unknown Astartes chapter. What they found was an entirely ruined world where chaos and xenos reigned supreme. What first began as an attempt to save lost brothers turned into a several millennia-long fight to retake the planet. During that time, the Astartes changed to accommodate a prolonged war on this world, and their name evolved into the "Deep Angels" with a mission to seek and purge all evil in the watery depths.
Desert Hawks		The Desert Hawks are a loyalist non-Codex compliant Successor Chapter created from the lineage of the ancient and heroic White Scars during the 8^th Founding. It's a small and endangered Chapter with only three ordinary companies left after the Soul War - a hard won victory almost 300 years ago against the Chaos Lord Haman-Maat of Tzeentch and his daemons. This victory nearly destroyed the Chapter.
Destroyers of Worlds		The Destroyers of Worlds, or Kshatriya as they call themselves, are an 8^th Founding White Scars Successor Chapter infamous for their excessive brutality and violence. This Chapter has garnered a reputation as being notorious and feared for their extremely brutal methods when fighting. Their reputation is such that when their name is spoken, those who know of them fall into a fearful silence as they pity the world that is about to suffer the wrath of the Destroyers of Worlds.
Diamond Knights		The Diamond Knights are a recently created Ultima Founding Successor Chapter of the Ultramarines comprised entirely of newly revealed Primaris Space Marines. This chapter, unlike their predecessors and fellow successors, is only semi-adherent to the Codex Astartes. Despite being a young chapter they have fought many battles on behalf of the Imperium and are on constant crusade to defend Mankind from all who would do them harm.
Diamondbacks		The Diamondbacks are a loyalist Space Marine chapter created in M36 from the gene-seed of the stoic Imperial Fists during an unknown Founding. Hailing from the harsh desert world of Tejaz, this Chapter are notable adherents of the Codex Astartes. However, they have been noted for being unusually adept at their marksmanship skills, and have a higher than normal number of designated marksmen within their ranks. Despite such discrepancies, the Diamondbacks have continuously stood steadfast against the Forces of Chaos, standing eternal vigil against signs of threats to their home system and those Imperial worlds in surrounding systems. However, despite their long and glorious battle-record, this Chapter is held in suspicion by the Inquisition due to their unusual mastery at marksmanship and highly independent streak, and have on occasion, clashed with one another down the long millennia.
Dominators		The Dominators are a loyalist Space Marine Chapter derived from gene-seed of the stoic and unforgiving Iron Hands Primarch Ferrus Manus. Since their inception, the Dominators have been known as a divergent Chapter that loosely follows the edicts of the Codex Astartes. Created during a now-forgotten founding the Dominators have been known throughout the Imperium for their brutality in exterminating Chaos. Due to their seething hatred for Chaos, the Dominators will stop at nothing and will go to great lengths to extinguish the flames of sedition caused by those who follow the Eightfold path. Even though this Chapter possesses unwavering loyalty to the Emperor of Mankind, they often look down upon normal humans as weak sacks of flesh that are easily corrupted by Ruinous Powers. They believe in the incorruptible will of bionics and the machine.
Doom Bringers		The Doom Bringers is a Loyalist Space Marine Chapter of unknown genetic lineage raised during the 3^rd Founding at the dawn of M32. An ancient Chapter, the Doom Bringers are perhaps one of the oldest Space Marine Chapters to have ever existed. Evidence for this lies in the annals of Imperial history, where the Doom Bringers are mentioned down the long millennia taking part in many notable campaigns and Imperial Crusades. Despite their long and glorious history to the Imperium of Man much of their origins are shrouded in mystery, with the few records still intact being senseless and peculiar.
Doom Fists		The Doom Fists are a Loyalist Space Marine Successor Chapter created during the 23^rd Founding, to so-called 'Sentinel Founding', from the lineage of the stoic and uncompromising Imperial Fists. Upon their inception, the newly created Chapter faced ill fortune during its maiden voyage and disappeared into a warp rift. After a suitable period of time with no further communication, the Chapter was declared lost in the warp and mourned on Terra and the Bell of Lost Souls was rung 1,000 times - one dolorous ring for each lost battle-brother. However, fate would eventually intervene and the lost Chapter would return back to the Imperial fold after missing for nearly two millennia, despite only a year and a half passing for the missing Chapter. Having undergone an ordeal of epic proportions, the Chapter had become hardened and stoic, to the point of aloofness. Their experience changed the Chapter in profound ways and forever after affected how the Chapter organised itself and deployed into combat.
Doom Hunters	Pict-File Unavailable	The Doom Hunters are a Loyalist Space Marine Chapter of unfortunate and mysterious origin, and very few outside of the chapter know it and live for very long after learning their secrets. Officially, this Chapter is well-hated traitors within the Imperium, classified as a renegade chapter who sided with the traitors by pure necessity for survival. In a "clever scheme" by the Inquisition, the Doom Hunters "feigned" betrayal at the behest of certain Inquisitorial parties in order to destroy the heretics from the inside. These parties remained the Chapter's only contacts and connection to the Imperium that they still secretly served. Mostly. However, now that their secret is revealed, there is no need for subterfuge. The Inquisition were in a rough patch politically and needed a win desperately. The Doom Hunters obliged, and their skill in dealing with the daemonic threat of being close to the Grey Knights made the story semi-passable.
Doom Sentinels		The Doom Sentinels are a venerable Loyalist Adeptus Astartes Chapter created during the 3^rd Founding from the Salamanders. Known for their ruthlessness and determination, the Doom Sentinels have garnered a reputation of being absolutely merciless towards their enemies, or protecting the people of the Imperium. What information about their origins were lost during the 7^th Black Crusade, also known as the 'Ghost War', when their homeworld of Quicksilver II was attacked by the dreaded Black Legion, though the world itself survived. Along with being one of the few loyalist chapters to still used chain-axes, the Doom Sentinels are noted to have enhanced strength surpassing what Space Marines are supposed to have, as well as greater durability. This mutation has been greatly used by the Doom Sentinels due to their chosen fighting style.
Dormant Sons		The Dormant Sons number among the most mysterious and obscure of the Imperium's Adeptus Astartes. Operating almost exclusively within the Halo Stars from their ocean homeworld of Reila V, the Dormant Sons are a terrifying sight on the battlefield. Deploying most often in full chapter strength, the Dormant Sons release drop ships from low orbit, and the resulting fire and turbulence can cause planet-wide storms that last for years. The Dormant Sons are deeply religious and secretive, worshipping the God-Emperor in a form that, if it was known in detail by the Ecclesiarchy, would certainly be retribution. While their true origins are unknown, that they have been seen to work alongside the Unforgiven on occasion suggests that they share the gene-seed of Lion El'Johnson.
Draconian Impalers		The Draconian Impalers are a venerable loyalist Successor Chapter of the ancient and valiant Blood Angels created during the 3^rd Founding at the dawn of M32. Down the millennia, this Chapter has garnered a reputation for their savage mien and use of unconventional tactics, and were eventually given an ultimatum by their Progenitors; lose all contact with their Founding Legion or change their ways. The Draconian Impalers chose to lose the support of Baal, and become a Chapter apart from their fellow Chapters of the Blood.
Draconian Wardens		The Draconian Wardens are the break-away chapter from the Astral Carbines, and are led by Julo Neronius, who had been the 3^rd Company Captain. Julo Neronius requested the creation of the Draconian Wardens in a petition to the High Lords of Terra after Darian Skyborne, the Astral Carbine's chapter master, died and, in his will, named Arius Diven, a relatively young 1st Company lieutenant, the rank of chapter master. Miraculously, the High Lords agreed with Julo and granted his request, paving the way for the creation of a new Chapter. The Draconian Wardens were created with much the same mission of the Astral Carbines - to save planets lost in the Imperium Nihilus which the Indomitus Crusade couldn't yet reach.
Dragon Guard		The Dragon Guard are an Astartes Chapter of Unknown Founding and descent, although there is evidence that points towards an early founding, perhaps even as early as the Second Founding. This Chapter hails from the mountainous world of Thel where great flying reptiles dominate the sky. These giants give their name to the Dragon Guard who descend on their enemies on great wings, their weapons fiery breath burning away the darkness.
Dragonkin		A strange chapter shrouded is disturbing rumors and deeds, the Dragonkin were created during the ill-fated 21^st 'Cursed' Founding from the ancient and venerable Salamanders. Whilst they would ordinarily be investigated and sanctioned by imperial authorities the Dragonkin appear to have powerful allies in the Holy Inquisition, most notably the Ordo Malleus. Though they appear to have avoided the uncontrollable mental and physical abnormalities of many of their brethren in the 21^st Founding the chapter appears to have an almost palpable aura of death and ending about them.
Dragons Amaranthine		The Dragons Amaranthine are among the few unacknowledged sons of the Primarch Vulkan. Believing themselves to be successors of the vaunted and venerated Salamanders chapter, the Dragons Amaranthine bear their heredity with pride, and keep true to many of the tenants espoused in their primogenitors Promethean cult. The Chapters home system of Jemenaius hosts three habitable worlds, on of which is an adeptus mechanicus forge world, which creates arms and armaments for the chapter and the region. This includes of production of Dreadnought Sarcophagi, which the Dragons possess in great numbers, these have become the saving grace of the chapter since suffering grievous casualties as a result of false information from an excommunicate Rogue Trader.
Dragons Sanguine		The Dragons Sanguine are a Successor Chapter of the vaunted and noble Blood Angels. Created in M35 during the turmoil at the start of the Nova Terra Interregnum the High Lords of Terra said a new founding must be created in order to pacify any rebellions that started to occur. The Dragons Sanguine were one of those chapters that arose during the 9^th Founding. The Chapter was created in the Segmentum Tempestus in order to train for the time when they must be called to bring the Emperor's justice on those who left the Emperor's light. As their first mission the chapter participated in the Axon Crusade 50 years after they were created.
Dragons of Suzanoo		The Dragons of Suzanoo are a Loyalist Successor Chapter created from the wild and untamed lineage of the White Scars during the 23^rd 'Sentinel' Founding. This Chapter stands eternal vigil over the planet of Suzanoo, an isolated feudal world located in the Eastern Fringe of the Ultima Segmentum. Like their genetic forebears, the Dragons of Suzanoo are an honourable and fierce Chapter. However, they adhere to a strict code that defines how they conduct themselves, both in war and in peace. The code of Bushio, known as 'The Way of the Warrior' emphasizes a life of virtue and integrity and is encapsulated in a warrior's honour, which is seen through an individual's actions and choices during their lives.
Dragon's Crater		The Dragon's Crater were a mysterious and enigmatic Loyalist Adeptus Astartes Chapter created during the 20^th Founding from uncertain descent. The chapter was declared as traitors for just disappearing one day. It is unknown which Primarch the Dragon's Crater descend from, although there is some evidence indicating these Astartes larger-than-normal physiques as well as some similar physical mutations are that of the Salamanders. The Dragons were designed to hit hard while keeping the enemies out of arms reach. They were a fierce and extremely loyal chapter that was sent to planets to clear out xenos invasions and infestations. Their weapons were designed to blow through enemies with ease, utilising the entire spectrum of known Astartes weapons available. However, during their fifth deployment, the Chapter mysteriously vanished. The Imperium ultimately decided that they be declared Traitoris Perdia for desertion.
Drakes Encarmine		In the Sanguine Brotherhood, few Chapters are regarded with more dread and wary respect than the forbidding and grim Drakes Encarmine. One of the few Chapters known to hail from the 13^th "Dark" Founding, the Bringers of Revelation are a nightmarish force of annihilation, where they go, fiery destruction follows. Such a bleak and devastating existence would ordinarily see such a Chapter liquidated by the Inquisition, and indeed there have been calls for that action to be taken, however, the Drakes Encarmine lack the cruelty and malice of Chapters such as the Marines Malevolent. Theirs is a desolate pragmatism, done without cruelty. The Chapter see themselves in a similar manner to the Angels Tears of the old Ninth Legion, the final, horrific sanction. They are the fire which burns away the old, making way for something greater, more beautiful.
Drakes of Deathfire		The Drakes Of Deathfire are an ancient and honourable Loyalist Successor Chapter of the Salamanders whose exact founding is unknown. However, the Chapter maintains they are one of the original Successor Chapters created in 021.M31, following the dissolution of the original Space Marine Legions, which were broken down into smaller formations known as Chapters, consisting of only 1,000 Astartes each. Despite the Drakes claims, Imperial savants have been unable to determine the veracity of such claims, though they have been mention in several extent accounts down the long millennia of the Imperium's historical archives. The Drakes of Deathfire are a crusading, non-Codex compliant chapter, meaning they do not follow the dictates of the Codex Astartes. The Drakes Of Deathfire believe heavily in the Promethean Cult and center themselves around bringing Nocturne's light and warmth to the imperiums citisens and those in it unable to defend themselves, and its, the God-Emperor's and Vulkan's rage, fury, and flame upon the alien, mutant and the heretic.
Dread Hands		The Dread Hands are a Loyalist chapter of Space Marines that were created in the 4^th Founding, - following the War of the Beast - this Chapter is descended from the stoic and unforgiving Iron Hands. Since the destruction of their oceanic homeworld of Liobos, the Dread Hands have become an entirely fleet-based chapter, sending the might of their naval forces wherever the High Lords of Terra command them.
Dread Knights		The Dread Knights are a Dark Angels Successor Chapter from the 21^st Founding, known as the 'Cursed Founding'. To many of the scions of the Lion the Dread Knights are considered to be a rabid hunting animal or a blunt instrument, unleashed by Lord Azrael when word of a potential member of the Fallen reaches their ears, for when they are set upon the trail of one of the hated Angels the brother-templars of the Dread Knights are unrelenting, willing to rampage through entire systems to find and capture even a single one of their traitorous kin.
Dusk Howlers		The Dusk Howlers, known as the Vlka Hrímherjar (translated as the 'Wolves of Hrímgard'), are an Ulitma Founding Successor Chapter comprised entirely of Primaris Space Marines, created from the lineage of the mighty Space Wolves. Their inception took place in the wake of Abaddon the Despoiler's 13th Black Crusade in 999.M41. The Dusk Howlers were created as a shock-assault force, to take back those worlds lost to the Traitor Legions in the wake of the formation of the galaxy-wide tear in reality known as the Great Rift. This Chapter is also known to make up part of the 'Sons of Russ', an unofficial collective comprised of several recently created Space Wolves Successor Chapters.
Dusk Stalkers		The Dusk Stalkers, known to their fellow Sons of Russ as the 'Vlka Jörmherjar' ('Wolves of Jörmungandr'), are a ferocious Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created from the lineage of the savage Space Wolves and raised during the Ultima Founding circa 999.M41. In the years following thier founding they have also joined an Unofficial Collective of those Chapters descended from Leman Russ, known as the Sons of Russ, they have joined together to stand sentinel over the Eye of Terror, attempting to complete their Primarch's hope of containing the foul denizens of that blighted place.
Dusk Vultures		The Dusk Vultures is a semi-Codex-compliant Loyalist Space Marine Chapter, formed during the 26^th Founding who can trace their genetic lineage back to the Raven Lord, Corvus Corax, via the Raptors Chapter. They mostly act in the Ultima Segmentum and have fought multiple times against what was later identified as the Hive Fleet Kraken. After having suffered major losses during the second and Third Tyrannic War and the opening of the Cicatrix Maledictum, the chapter has received the help of Lord Guilliman's Ultima Founding, bolstering its ranks with fresh-from-training Primaris Astartes.
Dust Knights		The Dust Knights are an enigmatic Chapter of the Adeptus Astartes created during an unknown Founding and of uncertain origins, though most sources point to the Raven Guard. Mysterious, the Dust Knights rarely speak to other Imperial forces, let alone fight alongside them, coming and going as they please. Many Commanders, even fellow Space Marines, have noted how eerie these Adeptus Astartes are. Operating near the Fringe Worlds between the Segmentum Obscurus and Segmentum Ultima, the Dust Knights have struck against the Forces of Chaos, Tau, Tyranids and so forth, causing mayhem amongst their ranks. Despite their tactics and attitude, the Dust Knights value the lives of Imperial citizens and are willing to risk their lives to avoid civilian casualties.

Name	Image	Notes
Ebon Angels		The Ebon Angels are an 8^th Founding Successor Chapter to the Silver Lions making them part of Lion El'Jonson's lineage and the Unforgiven. The chapter was founded at the behest of the Supreme Grand Master of the Silver Lions similarly to the Disciples of Caliban and they are a semi-Codex compliant chapter. The Ebon Angels also take part in the hunt for the traitorous Fallen so they can clear the stain from the honour of the Unforgiven and avenge the Lion. The Ebon Angels were created to expand the Unforgiven's capabilities for hunting the Fallen and will pursue the Fallen relentlessly often taking oaths to track down a particular Fallen that the chapter has been made aware of, with these small teams of Oath Hunters leaving the chapter for possibly years on end whilst they hunt their prey.
Ebon Butchers		The Ebon Butchers are a proud Loyalist Successor Chapter of the Silver Eagles, who themselves are descended from the proud lineage of the heroic Primarch Roboute Guilliman. They were created during the 23^rd Founding, the so-called 'Sentinel Founding'. Uncommonly amongst the Successor Chapters descended from the lineage of Guilliman, the Ebon Butchers are a bellicose and unforgiving Chapter, justifying their acts of butchery and harsh punitive actions as appropriate punishment for those that would make truck with the Ruinous Powers or turn from the light of the Emperor. For this Chapter, the ends justify the means, and they intend to enact their righteous indignation upon the foes of Mankind as they see fit.
Ebon Host		The Ebon Host is a Successor Chapter of the venerated Angels of Absolution, a chapter from the lineage of the I^st Legion - the Dark Angels. The Ebon Host can root its creation during the 13^th 'Dark' Founding, a founding from which few chapters can definitively trace their inception. Like their forebears, they do not consider themselves amongst the Unforgiven, believing they have done more than enough to repent in the eyes of the Emperor, and the Lion. The Ebon Host adopted many ways from their forebears however refused to incorporate the unique 1^st and 2^nd companies, instead staying Codex-compliant, for a time. It was not three centuries after their founding that their entire chapter seemed to change, traditions stripped away and replaced, seemingly changing their organization for little reason, and the abandonment of any hope to settle their chapter, instead using a newly acquired vessel as their fortress-monastery. However, the most drastic of changes was their abandonment of their fellow Sons of the Lion, as if they had done wrong by the Ebon Host.
Ebon Knights		The Ebon Knights are an ancient and proud Chapter whose origins are found in the chaotic centuries following the Horus Heresy. They were founded during the 2^nd Founding as a Successor Chapter of the venerable Dark Angels Chapter. Their home world of Shadowmehr is located in the Ixaniad Sector in the Segmentum Obsucrus. Here, the insular Ebon Knights have stood silent vigil over their demesne, ever vigilant against encroachment by the Forces of Chaos or malevolent xenos for nearly eight millennia. For unknown reasons, the Ebon Knights are shunned by their Progenitors and fellow Unforgiven Chapters. The exact reason for this schism remains unknown to outsiders, but Imperial scholars have been able to speculate, tracing the most likely origin of this rift to the mid-32^nd Millennium, during the so-called Crimson Blade Campaign, in the Scarus Sector. Despite their cold relations with their fellow Scions of the Lion, the Sable Knights have garnered a reputation for being honourable to their allies and implacable to their foes. This Chapter's extensive list of valiant deeds has even seen them come close to matching Chapters of more ancient provenance and heritage.
Ebony Dragons		The Ebony Dragons are a Loyalist Space Marine Chapter created during an Unknown Founding and from uncertain lineage, although it was sometime before M36. During the latter years of M36, the Chapter's homeworld of Charterous was engulfed by a massive warp storm and was eventually swallowed whole and pulled into the Immaterium. Declared lost, it was believed that the Ebony Dragons had disappeared for all time. But during the closing years of M41, with the destruction of Cadia and the formation of the galaxy-spanning warp phenomena known as the Great Rift, the long-lost world of Charterous was vomited back into reality. But the Ebony Dragons' long sojourn in the warp had transformed the battle-brothers of the Chapter, granting them powerful psychic abilities. The Ebony Dragons are often treated with open suspicion and hostility, for it was believed that no Space Marine Chapter could remain untouched by the predations of Chaos for so many millennia.
Eclipsed Wardens		The Eclipsed Wardens is a unique and altruistic fleet-based, Space Marine Chapter of the Adeptus Astartes. Created during an unknown Founding, this Chapter was created to perform missions of rescue and salvation. The chapter diverged from their Salamanders lineage, adopting a unified colour scheme with their original chapter's heraldry and the symbolic Unity gold eagle. Their history is characterized by an unwavering dedication to recovering lost and stranded Space Marines, regardless of their origins, from the fringes of forgotten battlefields.
Educators		The Educators are a small and secretive loyalist non-Codex compliant Space Marine Successor Chapter created during the Ultima Founding from an unstated lineage and composed entirely of newly revealed Vanguard Space Marines. Due to the similarity of the gene-seed it is believed that the Chapter originated from the Mentors, but this is not entirely confirmed by the Adeptus Mechanicus.
Electric Wardens		The Electric Wardens are a Loyalist 24^th Founding Chapter of the Adeptus Astartes, that was created from uncertain lineage. They were originally a fleet-based Chapter until the events of Voltan's Descent. This Chapte is known for being a close ally to the forge world of Sinbura which is well-known for its knowledge about electricity and its weaponising it. More obscure allies are the Electro-Priests of the Adeptus Mechanicus since both share an affinity for weaponised electricity. The Electric Wardens often operate on a strategic level of a campaign and bring down the entirety of their Chapter's strength onto the battlefield where they are needed the direst.
Ember Drakes		The Ember Drakes are an ancient and honourable Loyalist Space Marine Chapter that was created during the 3^rd Founding in 001.M32. Due to their similar heraldry, chthonic traditions, beliefs and practices, the Ember Drakes are suspected to have been created from the lineage of the venerable Salamanders of Nocturne. Like their supposed forebears, the Ember Drakes are also well known for their similar humane treatment and concern for the lives of innocent citizens of the Imperium as their supposed Progenitors. However, their divergent beliefs in the Promethean Cult and reverence for their Primarch Vulkan above all else, whose Chapter cult is centered around his worship, is considered unseemly by the Salamanders and not in keeping with their Primarch's original teachings.
Ember Sharks		The Ember Sharks are a Loyalist Space Marine Chapter created during an Unknown Founding, hailing from the lineage of the Primarch Corvus Corax. Since at least the middle centuries of M31, this bellicose Chapter has sailed the Outer Dark in the Segmentum Obscurus, silently watching for any threats that may come. In their mobile fortress-monastery, the Ark of the Furnace, a Chapter Barque, the Chapter continues their eternal vigil, silently watching and waiting for any threats that dare assails the realm of Mankind. That the Ember Sharks come from the gene-line of Corax is unquestioned, yet they are of brooding countenance, and utilize brutal terror tactics in order to cripple the foes of the Imperium before they are slaughtered by the vengeful marines of this Chapter.
Emerald Vipers		The Emerald Vipers Chapter is a Codex-compliant Successor Chapter created from the lineage of the Ultramarines during the recent Ultima Founding, consisting purely of Primaris Space Marines. The chapter mainly operates from the Death World of Viridium in the Ultima Segmentum on the Eastern Fringe, on the edge of the Ultramar sector bordering the territories of the T'au Empire and the Herzavar Sector. Led by their charismatic Chapter Master and former Veteran Sergeant of the Ultramarines 1st Company, Salvatus Augustus Severus, they serve as the eyes and ears of Ultramar, patrolling its vast borders for any incursion that might occur, be it traitor, xenos or daemons.
Emerald Spears		The Emerald Spears are a loyalist Space Marine Chapter created from the lineage of the heroic Ultramarines during the 25^th 'Bastion' Founding. Since their founding they have become notable for their exceptional level of coordination and teamwork. The Emerald Spears are ruthless warriors who pursue their enemies until every last foe has been slain. With tactical precision and fearless resolve do the Emerald Spears wage war on the enemies of the Imperium. Every battle is meticulously planned, every foe tactically analysed and every ally carefully scrutinised to ensure that victory is achieved in the most efficient manner possible. Then, when the battle is won and the fallen counted, all is recorded once again, the better to serve the Emerald Spears in their next war.
Emperor's Legion		The Emperor's Legion are an ancient and proud Loyalist Successor Chapter created from the lineage of the Primarch Roboute Guilliman. Created during an unknown founding, this venerable Chapter is believed to possible hail from the 2^nd Founding, which occurred in 021.M31. However, there are no mentions of the Emperor's Legion in official Imperial records until at least the early decades of M32. Steeped in deep traditions and ancient practices, this Chapter resembles the culture of Old Earth's Romanii in a lot of similar ways. They are very organised and strict in their ways of war and have earned a reputation as merciless and fearless warriors in battle. Despite being a Successor Chapter of the Ultramarines, the Astartes of this Chapter are strict adherents of the worship of the Imperator as a God, but are not officially a part of the Ecclesiarchy.
Emperor's Liberators		The Emperor's Liberators, known formally as the 'Imperatoris Liberatae', are a formerly loyalist Space Marine Chapter created from gene-seed of unknown origins during an Unknown Founding. During their creation Adeptus Mechanicus fleshcrafters made mistakes in the handling of the future chapter's gene-seed. Records of this chapter's founding were destroyed by said officials in order to save careers and the lives of those responsible for said mistakes. The chapter's history is one that tells of heroic beginnings, dutiful service, and the time of strife it endures to this day. A stinging irony that hangs over every battle-brother of the chapter is that despite their name and circumstances on paper, they are now more enslaved than ever. As the chapter continues to fight a never-ending war for its ideals and a war against fate itself, one question remains: What is the price of freedom?
Emperor's Nightmares		The Emperor's Nightmare is a Loyalist Successor Chapter that hails from the genetic lineage of the Raven Guard that was created during the 23^rd Founding, the so-called 'Sentinel Founding'. This Chapter bears the curse of a bizarre mutation within their gene-seed. The Catalepsean Node, the organ which aids the Adeptus Astartes in keeping combat-ready regardless of fatigue, is in a state of decay. This means the Nightmares cannot sleep for months on end, before suddenly and unconditionally falling to slumber. This has influenced the Nightmares' tactics, as each battle-brother must be able to take over from their fellows at a moment's notice. Their Raven Guard heritage is a major contributing factor too, the stealthy doctrine of their parents but clashing with their love of shock and awe warfare. This all mixes into a chapter with a strange divergence of warfare.
Emperor's Own		The Emperor's Own is a Loyalist Space Marine Chapter created during an Unknown Founding and are of uncertain origin. They were first listed in official Imperial records in early M36. The Emperor's Own do not count as one of the Hell Warders Chapters, having been based on Imperator Victor in Occidentis Auster of Sector Occident Prime since long before the opening of the twin warp rifts known as the Hellgates. The Emperor's Own primarily concern themselves with the defence of the sector form periodic attacks from Ork WAAAGH!s launched from Calverna, and as such, are not a part of the Hell Warders Chapters.
Emperor's Reapers		The Emperor's Reapers Space Marine Chapter is a loyalist crusading chapter of the Adeptus Astartes that loosely follows the dictates of the Codex Astartes. This ancient and venerable Chapter can supposedly trace their lineage back to the Second Founding, however, the validity of such claims has been difficult to verify due to the passage of millennia, lost records and human error. It is unknown exactly whose lineage this mysterious Chapter is actually descended from, but rumour and conjecture continues to abound amongst Imperial scholars. The Emperor's Reapers excel in close-quarters actions, often utilising a wide variety of close-range weapons, ranging from chain weapons, power weapons and even power scythes. This bygone (and often shunned weapon) is utilised exclusively by the chapter, one in which the Emperor's Reapers use as its primary weapon, above chain blades or other melee power weapons.
Emperor's Rifles		The Emperor's Rifles are a loyalist Space Marine Chapter of Unknown Founding and uncertain lineage. Hailing from the mountainous hive world of Parvat Obscurum, their origins are shrouded in mystery, as no records exist in Imperial databases. The only clue to this chapter's origins are passed down by oral tradition as folk tales and myths, which are perpetrated by men and Astartes alike. There are some indications in official Imperial records that this Chapter is possibly a rare Successor Chapter of the Raptors through the lineage of Primarch Corvus Corax. Citizens of Parvat Obscurum refer to themselves as the Gurukhali, which roughly translates to "Main Tribe" in the native tongue.
Emperor's Sentinels		The Emperor's Sentinels are a 23^rd 'Sentinel' Founding loyalist Space Marine Chapter of Ultramarines decent originally assigned to defend the Janus Sub-Sector from Ork attacks due to the sector's history of xenos raids. Since its founding the chapter has gone on to win many victories in the Emperor's name and has become particularly adept at combating xenos forces.
Emperor's Trident		The Emperor's Trident are a mysterious and little-known Loyalist Space Marine Chapter created during an Unknown Founding and of uncertain lineage. Not a lot of official information is known about this elusive chapter's past but recovered records state that the Emperor's Trident has been active since at least M34 or M35. They are masters of void warfare and boarding operations. Since the formation of the Great Rift, the majority of the Chapter that was out on campaign, lost contact with the 1^st Company and their Chapter Master. Despite this setback, the Emperor's Trident continues to stand resolute during Mankind's darkest hour.
Emperor's Wardens		The Emperor's Wardens is a Codex-compliant Space Marine Chapter of unknown Founding who's gene-seed comes from the heroic and much lauded Ultramarines Chapter. The Wardens are characterized by their fanatic devotion to the God-Emperor of Mankind and to the Imperium. The Chapter comes from the world of Thedosia, a feudal world ruled for millenia by a powerful aristocracy and oversaw by the Sanctum of Nimue, a sanctioned sect of the Imperial Cult worshipping the animistic force known as the Eternal Light, who defend its people against the dangers of the Galaxy and beyond.
Empyreal Revenants	Pict-File Unavailable	The Empyreal Revenants is a Loyalist Successor Chapter created from the lineage of the proud and noble Blood Angels during the Era Indomitus, formed in the wake of the Devastation of Baal. This newly incepted Chapter is comprised entirely of Primaris Space Marines, the next generation of the Adeptus Astartes who are larger, stronger and faster than their Firstborn brethren. This Chapter has dedicated itself wholly to the unenviable task of seeking out and hunting down the last remnants of the Hive Fleet Leviathan until nothing remained. Initially a fleet-based Chapter, the Empyreal Revenants pursued their prey relentlessly. Eventually, they encountered the Ryzantynium System during their never-ending pursuit of the hated Tyranids. Following a gruelling campaign, the Chapter claimed the world of Ryntioch as their Chapter homeworld and the system as their chosen demesne.
Enlightened Sons		The Enlightened Sons are a Codex Astartes-compliant Loyalist Space Marine Chapter created from the lineage of the proud and stoic Imperial Fists during an unknown Founding, though some Imperial scholars suspect it may have been in the Age of Apostasy M36. This suggests they hail from the rebuilt Imperial Fists Chapter following the near-disastrous War of the Beast.
Epsilon Tempests		The Epsilon Tempest is a Successor Chapter of the vaunted Ultramarines. Founded during the recent Ultima Founding with the introduction of the Primaris Space Marines. The chapter itself was created with the reawakening of the Primaris filling its ranks. Sharing the gene-stock of the Ultramarines, they are heavily influenced by the dictates of the Codex Astartes, however, unlike other Codex-oriented Chapters, they still understand the importance and necessity to break these rules when needed by adapting to the situation. The Name Epsilon originates from the sector the fleets watch over, taking the Sectors name in honour of the necessary watch.
Erelim		The Erelim are a successor chapter of the Dark Angels of an unratified nor direct founding that first became active during M37 following the events of the Ghost War. Taciturn, humourless and grim warriors modelled on the conduct and strictures of the Dreadwing, they are a force that harkens back to a time thought wholly lost in the ranks of the First. The tumultuous days of the 37^th Millennium exacted a heavy toll on the Dark Angels and thus they petitioned the High Lords of Terra to fund the chapter that would later become the Erelim. Though the Dark Angels originally considered the notion of disbanding the Dread Nights in favour of the newly found Erelim, it was the leadership of this fledgling chapter and some of the others in the Unforgiven that spoke in favour of keeping the Dread Knights in and amongst their ranks, sharing between them the role of the Dreadwing jointly.
Eternal Guard		The Eternal Guard also known as Aeterna Praesidio in High Gothic, is a Loyalist Space Marine Chapter from the 4^th Founding with their lineage classified by the Adeptus Administratum for reasons unknown to the chapter. They were founded to fortify the various imperial strategic worlds in the Ultima Segmentum against any enemies of the imperium, Orks and later on the duties included the possible defense against Tau expansions as well as restoring civil order in the fringes of the galaxy under imperial control. Because of their red luminescent eyes, they believe themselves to have a connection to Salamanders, though it has been hotly contested within the chapter's Apothecarion.
Eternal Paladins		The Eternal Paladins is a loyalist Chapter that is mostly Codex Astartes complaint, with a few notable deviations. They are a Successor Chapter of the stoic and heroic Imperial Fists, founded during early M38 as part of the 23^rd Founding, the so-called 'Sentinel Founding'. Their homeworld is the feudal world Oighir, which is located in the Scead 10 System.
Eternity Invictors		The Eternity Invictors are a Loyalist Successor Chapter descended from the proud lineage of the stoic Imperial Fists, created during the 25^th Founding, the so-called 'Bastion Founding'. They currently operate as a fleet-based chapter due to the destruction of their home world Tradex IV, in 876.M40.
Eyes of Ferrus		The Eyes of Ferrus (known also as the 'Eyes of Iron') are a Loyalist Space Marine Chapter and are a confirmed successor of the Iron Hands. They are of the recent Ultima Founding in which their Chapter mostly consists primarily of Primaris Space Marines. This chapter suffers from a unique gene-seed flaw that some speculate to be pre-ordained by Divine will or by dark intervention, depending on who you ask.
Exalted Blades		The Exalted Blades are an 11^th Founding Imperial Fists Successor Chapter that was born out of the Feast of Blades, the martial tournament held between the Sons of Rogal Dorn. When one of the Feasts became the target of a Chaos invasion the Imperial Fists and their successor Chapters of the day pooled their resources and formed a joint garrison to safeguard the region of space around which the Chaos incursion had originated. Years later, the many petitions made by the Chapter Masters of the line of Dorn were answered and a new Founding was sanctioned by the High Twelve. The surviving members of the joint garrison would go on to be among the founding members of the new Chapter, serving as both its officers and its veteran core. And so the Exalted Blades were born.
Exalted Guard		The Exalted Guard are a Loyalist Successor Chapter created during the ill-fated 21^st Founding, the so-called 'Cursed Founding'. Officially, their genetic lineage is unknown. However, certain practices and tactical doctrine indicate this Chapter might be descended from none other than the noble Primarch Sanguinius. However, despite such claims, the Exalted Guard does not get on well with most other Chapters, with the exception of the Blood Drakes, a Successor Chapter of the Salamanders.
Exalted Paladins		The Exalted Paladins are a Space Marine chapter which is a Successor Chapter to the Iron-bound Thanes (before the World Burning and the renaming to Ashen Thanes) and are descended from an unknown Primarch. They are renowned throughout the Imperium for their fanatical zeal towards worshipping the Emperor and are one of the few Chapters to go from being fleet-based to possessing their own homeworld to call their own.
Exalted Seraphs		The Exalted Seraphs are a Loyalist Space Marine Chapter supposedly created from the lineage of the stoic Imperial Fists during an Unknown Founding, following the Reign of Blood sometime in the 36^th Millennium. They are notable for being a bellicose and zealous Chapter, who, unlike other Space Marine Chapters, are notably strict adherents of the Imperial Cult, believing in the Emperor's divinity and humanity's manifest destiny to dominate the stars. Though they initially believed they were descended from the lineage of the Imperial Fists, it was recently revealed that they are actually descended from the lineage of the Dark Angels. For reasons unknown, they are looked upon with great acrimony and distrust by the Chapters of the Unforgiven.
Excarnators		The Excarnators are an Ultima Founding Successor Chapter of the proud and merciless Iron Hands. This stalwart Chapter is entirely comprised of newly revealed Primaris Space Marines. The Excarnators exist to defeat the heaviest armor employed by various xenos and the Traitor Legions. They are responsible for reinforcing the Jericho Reach and Imperial Knights along the Eastern Fringe. Based on their natural resistance to plague and illness, Inquisitors of the Ordo Sepultrum and Ordo Malleus choose to closely partner with the Chapter to combat the spread of pestilence by Nurgle and banish the daemons spawned as a result of its presence.
Excruciators		The Excruciators are a Loyalist Codex-compliant Successor Chapter created during the 6^th Founding from the lineage of the heroic Salamanders. In mid-M36, the Chapter suffered the catastrophic loss of the majority of their Chapter upon the world of Rylor at the hands of a notorious Chaos Warband known as the Knives of Nurgle. A surviving squad was ordered to depart the battlefield for the Chapter's legacy to survive. Escaping the massacre, this lone squad of surviving battle-brothers made their way back to their Chapter Homeworld, where they placed themselves in stasis and were eventually forgotten, until their rediscovery in late M41. Offered the chance for redemption, they underwent the process of becoming Rubicon Primaris and were gifted with the means to create a new generation of Space Marines to rebuild their Chapter.
Exercitus Imperialis		The Exercitus Imperialis, commonly known by their Low Gothic name, the 'Imperial Host', are a 26^th Founding Successor Chapter, created from the lineage of the stalwart and heroic Ultramarines. Adopting combat styles perfected by their predecessors of the Silver Centurions, they excel in phalanx infantry formations covered with overlapping fields of fire from their tactical and devastator squads with armoured support from their formations of Astartes Battle Tanks. They have defended the western borders of Segmentum Ultima since their inception, becoming experts in breaching operations and open field warfare in the process.

Faithful Shields		The Faithful Shields, referred to as the Holy Order of the Faithful Shields by its Astartes, are a renowned Codex-divergent chapter of Space Marines descending from the Imperial Fists. A highly pious chapter, the Faithful Shields see the Emperor as a god, and themselves as literal angels created to do his bidding in protecting mankind and crushing the enemies of it. The Faithful Shields have devoted themselves to becoming masters of shock assaults, maintaining a larger vehicle pool than many chapters would to supplement this style of war. Each marine has become a skilled warrior in close-quarters combat, whether it be melee or bolter combat in close conditions. They are known to take great pride in being a shield for the common citizen, understanding that they should protect the common man who cannot protect themselves.
Falcon's Claws		The Falcon's Claws are an ancient and ferocious 3^rd Founding Successor Chapter created from the lineage of the proud and savage lineage of the White Scars. Created in the wake of the Great Scouring, the Chapter took its namesake from the V^th Legion's ancient auxiliary order known as The Burgediin Sarhvu or 'Falcon's Claws', a small Order composed of veteran warriors that excelled as hunters and forward scouts on the battlefield, well known for their expertise in survival and the quiet elimination of enemy commanders. When this Chapter was formed at the dawn of M32, they carried on the traditions of their order, continuing to stalk the battlefields across various warzones, delivering swift and brutal death to those that would dare oppose Mankind's manifest destiny as the rightful inheritors of the galaxy.
Fangs of Fenrir		The Fangs of Fenrir is a loyalist Successor Chapter who descends from the wild and untameable lineage of the Space Wolves. The Chapter was founded during the Ultima Founding and is comprised completely of Primaris Space Marines. They are known for their savageness and absolute fury in close combat. They're at their very best when battling large armies in dense terrain. There they can single out a target and destroy it. Being Sons of Russ, they excel at melee combat, but they still are respectable long-range combatants that can fight from a distance, because they are extremely precise with their bolters. Coming from the icy planet of Middenheim, they can resist the cold and can survive at temperatures that would kill an ordinary human. In battle, they can often be seen using wolves and Vargs as mounts to outrun their foes.
Fatebinders of Tyr		The Fatebinders of Tyr, known also as the Fatebinders, is a loyalist Space Marine Chapter created during an Unknown Founding from the lineage of the stoic and stalwart Imperial Fists. Much of the lost records of their past history is passed down orally from brother to brother, down the millennia. The Fatebinders' main mission is to cull and recover lost knowledge and defend their Chapter homeworld of Tyr and the systems surrounding it.
Ferric Bulls		The Ferric Bulls are a loyalist successor chapter of the remorseless and calculating Iron Hands, founded in the 23^rd 'Sentinel' Founding. They, like their predecessors, have garnered a reputation for mechanical, heartless precision in the face of their enemies, however, they seem to be far more accepting of the weakness of flesh than some other groups of Iron Hands Space Marines.
Ferric Kings		The Ferric Kings are an Ultima Founding Chapter, native to the Corribra Sector, Much like the Knights of Thunder Chapter, the Ferric Kings were raised in the hopes of plugging several defensive holes in the Southern Segmentum Tempestus, and so have made it their mission to stand watch over the Corribra Sector, defending it against whatever vile threats might rise from the Veiled Region beyond. While having existed for less than a century, the Chapter has had an embattled and glorious history. Their heroic deeds have gained them favour amongst the ruling magos of several forge worlds, allowing them access to some of the Imperium's rarest and most cutting-edge technology.
Ferrus' Children		Ferrus' Children are a Codex Astartes-compliant Loyalist Successor Chapter of the unforgiving Red Talons, who themselves are descended from the lineage of their unforgiving and stoic Primarch Ferrus Manus. Active since the middle of the 35^th Millenium, this fleet-based fighting force is known for its ferocity and stubbornness in battle, never fleeing combat in the name of their fallen primarch. They usually lend their forces to Astra Militarum's regiments, adding their stupendous firepower and highly armoured vehicles to the Imperial Guard's huge numbers to deliver a quick, efficient defeat to His enemies.
First Scions		The First Scions are a new, Codex-divergent Successor Chapter from the vaunted line of the Dark Angels. They are noted to have made major tactical and organizational deviations from the Codex Astartes, falling back to the tenets of the Lion after a disastrous campaign during the Indomitus Crusade. The chapter places great emphasis on honour and the legacy of their Primarch.
Fists Revenant		The Fists Revenant is a Renegade-turned-Loyalist Chapter through a Penitence Crusade to atone for the sins of the chapter. They were founded in the wake of the events of the War of the Beast by Loyalist members of the Fists Exemplar Chapter. Due to unforeseen circumstances, the First Captain of the Fists Exemplar was forced to align with an Iron Warriors Battalion to survive an attack by a massive greenskin fleet. Choosing to align themselves with their Iron Warriors allies, these Fists Exemplar Astartes further damned themselves when their commander killed a fellow Scion of Dorn the High Marshall of the Black Templars. This decision forced Zerberyn and his followers to walk the path of the traitor forevermore. Some but few of the Fists Exemplar disagreed with Zerberyn, most notably Captain Arcos of the 4^th Company. Captain Arcos and what remained of the 4^th Company left knowing they could not simply go back to the Imperium. These former Fists Exemplar eventually become the Fists Revenant.
Fists of the Gorgon		The Fists of the Gorgon are a Loyalist Successor Chapter created from the lineage of the stoic and unforgiving Iron Hands. They were created in the latter part of M37, a tumultuous period in Imperial history, where the Adeptus Astartes suffered the loss of dozens of Chapters through attrition or corruption by the Ruinous Powers. The Fists of the Gorgon was one of several Chapters created as a part of the 23^rd 'Sentinel' Founding and were intended to help shore up the losses and repair the power of the Adeptus Astartes. Since that bygone era, the Fists of the Gorgon have continued to stand sentinel over the Siovis System, but have answered the call of the High Lords of Terra, when called upon.
Flesh Rippers		The Flesh Rippers are an infamous Loyalist Chapter of unknown origin and Founding said to be created in the early years of M34, though there is some conflicting evidence on this in the Imperial records, with some reference to the Chapter existing as early as M32. This Chapter is suspected, due to their pale skin, to be descended from the Raven Guard but they are known to be extremely stubborn and have shown signs of paranoia and they are noted to fall into a berserk fury during battle similar to Blood Angels further clouding their origins. Others have claimed a link to the World Eaters Traitor Legion. Whatever their origins, the Flesh Rippers are bloody-handed monsters - vicious and violent beyond what is expected even of Astartes. They are Loyalists of the Emperor of Mankind though the significant evidence of major genetic flaws has led to their investigation on charges of heresy by the Inquisition.
Forge Templars		The Forge Templars are an unacknowledged Salamanders Successor Chapter created during the 4^th Founding in the middle centuries of M32 in the wake of the near-disastrous War of the Beast. In the course of their long and exemplary history, the Forge Templars showed all the qualities of the sons of Vulkan, along with a penchant for flamers and melta weapons. The chapter suffered heavy losses during the 13^th Black Crusade and the subsequent Noctis Aeterna, including a great part of their honoured Dreadnoughts. Thus the new Primaris reinforcements were warmly accepted by the Forge Templars.
Frost Claws		The Frost Claws are a now-extinct Successor Chapter created from the lineage of the proud and stoic Imperial Fists. Hailing from the frozen world of Marzanna's Rest, these sons of Rogal Dorn were obstinate and implacable. Their record before their extinction was one of countless victories won through sheer pugnacious resolve. Though they had innumerable victories abroad, in theatres that would've resulted in any other Chapter's destruction, it would be the battle of their own homeworld, which was revealed to be the Tomb World of a particularly demented force of Necrons, whose mania had led them to slide back into worshipping the C'tan. In this case a shard of the Void Dragon. Though the entire Chapter was present, and the Frost Claws put up an astonishing fight, the unstoppable waves of Necrons still wore them down. In the end, before their annihilation, then Chapter Master Andrei Borka charged three survivors; Koschei, Ivan Alois and Drago Jarek with reaching Terra and resurrecting the Chapter. Though eventually Koschei, the Chapter's de facto leader indeed managed to reach Terra, extremist elements within the Inquisition sought the Chapter's extinction. After their failed assassination attempt, Koschei disappeared, and the Frost Claws have been considered fully extinct.
Frost Reapers		The Frost Reapers are a semi-Codex Complaint Chapter, they were created during the 25^th Founding, the so-called 'Bastion Founding', from unknown lineage. This Chapter was formerly created to counter minor xenos threats and Chaos warbands in the Orion Sector located in the Segmentum Tempestus. The Chapter is known by its unique tactics with heavy weapons and their brutality in close combat. The Frost Reapers are stabilised on the Ice World of Ís'Kúlu and often recruit from the small underground cities that reside on the planet.
Fulminators		The Fulminators is a Chapter founded at the outset of the Era Indomitus during the Ultima Founding. A Chapter of Primaris Space Marines, the Fulminators formed part of Guilliman's Indomitus Crusade as one of many Ultramarine successor Chapters. Based in the Galeris System of Ultramar, the Fulminators divide their Chapter between the protection and restoration of the 500 Worlds, and the prosecution of Indomitus Crusade within the wider galaxy. (Note: This Chapter falls under the Expanded Universe category.)

Garuda Legion		The Garuda Legion are loyalist Codex-compliant Adeptus Astartes Chapter created during an Unknown Founding. There are no records trace the chapter's lineage of their Primarch, with the exception of a lone marking of a raven glyph on the gene-seed case. The Garuda Legion was created as a commendation from the High Lords of Terra to combat against Drukhari raids and Ork marauders as well as Chaos Cultist uprising across Segmentum Tempestus, specifically the Indonesyc Sector.
Gatekeepers		The Gatekeepers are an Imperial Fists Successor Chapter created during the 4^th Founding following the near-disastrous War of the Beast in the middle centuries of M32. This Chapter is also the de facto leader of the Astartes Chapters that make up the Hell Warders - a quintumvirate of five Space Marine Chapters - tasked to defend the Imperium against Chaos incursions from the Hellgates - dual warp storms located in the Segmentum Solar which are uncomfortably close to Holy Terra.
Gauntlets of Dorn		The Gauntlets of Dorn are a 4^th Founding Successor Chapter of Dorn's blood. They were formed in the wake of the disastrous War of the Beast in 546.M32, after the Imperium was brought to its knees and multiple Chapters of the Adeptus Astartes were effectively wiped out. The initial command cadre was formed from the loyalist remnants of a formerly Loyalist Chapter, the Emperor's Hounds, that had fallen to the insidious influence of Chaos in 345.M32. Only Captain Jedidiah, his chapter ancient and veteran, three marines, and Emperor's Champion and the surviving Neophytes remained loyal. After being thoroughly tested by Inquisitors of the Ordo Hereticus - physically, morally and spiritually, they were deemed acceptable to continue, with a close eye watching. Passing these rigorous test, the remaining loyalist Astartes were deemed 'free of heresy'. Following the successful completion of a 200 year long penitent crusade they were finally redeemed and granted the Emperor's forgiveness. During the 4^th Founding, Captain Jedidiah was granted the honor of becoming the Chapter Master of a new chapter, with the other marines aiding him.
Gershwin Company		The Gershwin Company is a strange and eccentric Renegade Space Marine Chapter founded by Pierrepont Gershwin. They were created during an Unknown Founding and of uncertain origin. Composed of three divisions, they are dedicated to unity among races, defense of the innocent, and peace through diplomacy. Their greatest belief is in the "Brotherhood of Life", meaning that all thinking creatures are linked, and that the best way to defeat an enemy is to make them your friend. They are also known for their unusual tactics on the battlefield, performing elaborate synchronized dances and singing in harmony to intimidate or confuse the enemy. The complete doctrine of the Company is found in Gershwin's Codex Musica, which outlines the basis of the Company. (Excommunicate Traitoris)
Ghast Knights		The Ghast Knights are a renegade Space Marine Chapter originally descended from the Gilded Knights, a 23^rd 'Sentinel' Founding Successor Chapter created from the lineage of the stoic and unforgiving Iron Hands. However, this is only known to the Ghast Knights and the traitorous Leviathan Dogma. The Inquisition has its suspicions, but they are based solely on anecdotal evidence. Despite this scrutiny, those that have fought by their side know them to be ardent defenders of the Imperium and its people. The Ghast Knights aggressively patrol their sector and answer any cry for aid with a company's worth of Astartes. Their presence is usually heralded by smoke bombs and deafening shrieks. (Traitoris Perdita)
Ghost Crusaders		The Ghost Crusaders are a loyalist Space Marine chapter of an Unknown Founding and uncertain lineage. Very little is known about the way structure of the chapter as they have no particular homeworld on record, making them officially a crusading chapter. However, there have been a multitude of records of these Astartes engagements as interestingly their fleets arrive when an Imperial Crusade is collapsing or when Imperial Hive Worlds are under siege. This leads some to speculate them to be a successor chapter of the Salamanders due to their selfless nature in defending Imperial lives. However, upon examination of some of their fallen, there were no visible mutations in their gene-seed commonly seen within the sons of Vulkan. Afterwards upon questioning an Apothecary of the chapter as he collected the gene-seed of the fallen, demanding to know who they were. The Apothecary only responded with the words 'Pulvis et umbra sumus' meaning "We are but dust and shadow," in High Gothic.
Ghosts of Nocturne		The Ghosts of Nocturne is a Loyalist Space Marine Chapter created during the Ultima Founding and is a Successor Chapter of the Salamanders. This all-Primaris chapter differs from its primogenitors in that it focuses on stealth and guerrilla tactics instead of slow, forward advances. The Ghosts of Nocturne see extensive use of units clad in Phobos pattern-Armor and prefer to ambush the enemy and cut them down quickly and effectively before melting back into the shadows. Unmasked and unarmored, the Ghosts of Nocturne are an unsettling sight to behold, with gaunt, wraith-like bodies, mottled grey skin and glowing pupilless blue eyes. They practice a ritual known as the Cleansing, in which they meditate completely engulfed in flames upon a large dais. Despite this, the chapter diligently adheres to the teaching of the Promethean Cult of their forefathers and are fierce allies to any who would defend the Imperium from her enemies.
Gilded Hammers		The Gilded Hammers are a Loyalist Chapter of Unknown Founding and unknown origin. An intentional flaw in their gene-seed means that their sense of hearing is greatly increased but they can not speak above a whisper. They venerate the Emperor and the nine Loyalist Primarchs as a pantheon of gods, with each company venerating one above the others. The unknowns of the Gilded Hammers are all done on purpose with many of their ancient relics having whatever previous decoration they once possessed, scoured before they first appeared. This Chapter specialises in void warfare, boarding actions, and heavily armored assaults. The Gilded Hammers are known to have a very close relationship with the Ordo Xenos and work for them often and to great effect.
Gilded Knights		The Gilded Knights were a now-extinct, loyalist Codex-compliant Successor Chapter forged from the lineage of the Iron Hands during the 23^rd 'Sentinel' Founding. Since their inception, this Chapter fought honourably for the Imperium until M.39 when a traitor in their ranks, Urlaban, destroyed the chapter from within and turned the majority to Chaos.
Gloam Strikers		The Gloam Strikers are a specialist Chapter created during the 25^th Founding, circa 405.M39. Though they hail from unknown lineage, they believe themselves to be a Successor Chapter of the mysterious Sons of Antaeus, who were created during the 21^st Founding, the so-called 'Cursed' Founding. Like their supposed genetic forebears, the Gloam Strikers are unusually large and robust physical specimens, even amongst their already superhuman kind - capable of surviving wounds and physical injuries that would kill even other Astartes. In battle, they deploy as a small strike force Chapter that specialises in extended-period assault operations, harsh environmental warfare and combat field engineering.
Gold Knights		The Gold Knights is a Loyalist Successor Chapter of the Adeptus Astartes created during an unknown Founding and from an uncertain genetic lineage. There is little information in official Imperial records regarding this mysterious Chapter's origins or when they were created. However, extant records indicate that they were more than likely created during one of the latter Foundings.
Gold Templars		The Gold Templars are a Space Marine Successor Chapter created in the 25^th 'Bastion' Founding. The chapter is a Blood Angels successor designed to spread wide across imperial space and is bolstered by a regiment of Guardsmen. They are known to induct members from other chapters when possible, especially from other Blood Angels successors. The Gold Templars are characterized by a more mundane affliction of the Red Thirst and Black Rage, which leads to a less spirited expression of the chapter's glory, and the chapter also develops psykers much less frequently. However, the marines are trained to better repair and manage their equipment more effectively than other chapters, due to the emphasis on operating in more sparse and restricted circumstances.
Golden Knights		The Golden Knights are an ancient Space Marine Chapter of Unknown Founding and unknown origin, though the paucity of surviving records points to this Chapter being Founded soon after the events of the Horus Heresy. However, much of their earlier history, from their inception onwards through M37, has been lost. During M38, a massive Chaos incursion of their Chapter homeworld, Zinthreon II, located in the Segmentum Obscurus, resulted in the destruction of most of the Chapter's records pertaining to their origins. The Chapter strays greatly from the dictates of the Codex Astartes and has nearly been declared traitors for several charges of 'legion building' after several cases where the Chapter's numbers exceeded the maximum allowable 1,000 battle-brothers. These charges would have led the chapter to be declared Excommunicate Traitoris if it were not for the chapter's creation of 'The Weeding' wars.
Golden Lions		The Golden Lions are a Loyalist Codex-divergent Chapter created during an Unknown Founding from the prestigious lineage of the stoic and stalwart Imperial Fists. Since its inception, this Chapter has suffered its fair share of tragedy, including losing almost all of its history. They also suffered the dual ignominy of having one company turning to Chaos and another company splitting away as renegades, forming their own separate Chapter known as the Red Swords. Due to these separate incidents, they have been kept under tight scrutiny by an Inquisitor of the Ordo Hereticus. Since that time, they have only taken part in campaigns in their own home sector, standing sentinel against the continuous threats from both xenos and heretic forces, which assail this region of space with great frequency.
Golden Panthers		The Golden Panthers were once a firmly-established 4^th Founding Chapter, established on the agri-world of Pyrathas. The Golden Panthers are successors of the stoic Imperial Fists and inheritors of Rogal Dorn's gene-seed, holding to a deep sense of honour that runs deeper than the blood they spilt. Honour, courage and utmost loyalty were the virtues they held. They pride themselves on melee prowess and commonly used shields alongside their weapons, creating near impenetrable shield-walls of infantry. However, their long history was sullied by their fall to the Ruinous Powers, years after the Ultima Founding, when Pyrathas was raided and laid waste to by an Ork WAAAGH! of the 'Acky 'Ands. The tide was broken, but not without cost, as Lycon Ascani, the First Company Captain, made a pact with a Khornate blade and sealed his followers to heresy. When they finally denounced the Imperium and joined Chaos, they became the Unbroken Warlords. The loyalist Golden Panthers now, despite their depleted numbers, fight to avenge their broken honour, led by Sarphus Hecton. Although Pyrathas is no longer the flourishing world it once was, it now acts as a memorial to the glory it once was.
Golden Seraphs		The Golden Seraphs is an ancient Successor Chapter that hails from the proud and noble lineage of the angelic Primarch Sanguinius. Created during the 2^nd Founding in 021.M31, following the end the Great Scouring, the great war of reciprocity against the vile Traitor Legions that occurred following the bloody galaxy-wide conflict known as the Horus Heresy. The Golden Seraphs inherited their Progenitor's pride on their ability to meet the foe head-on, no matter the odds. During this tumultuous time in Imperial history, those Chapters created during this particular Founding quickly garnered a reputation as savage and merciless Astartes, who willingly struck fear into the Imperial populace to scare them into compliance.
Golden Torches		The Golden Torches are a venerable 3^rd Founding Chapter. Their origins unknown, but some say they show resemblance in terms of beliefs to that of the burning righteous Salamanders. Furthermore, the Golden Torches are well known for their master-crafted weapons and armour, and high number of vehicles, just like the sons of Vulkan, further pushing the idea of their origins.
Gorgons of Extinction		The Gorgons of Extinction are a Loyalist Successor chapter created during the 4^th Founding sometime in the mid 500s.M32, descended from the gene-seed stock of the stoic and unforgiving Iron Hands' Primarch Ferrus Manus.
Graven Skulls		The Graven Skulls are recognized as a Loyalist Space Marine Chapter of unknown Founding and origin. These frightful and cryptic marines are a more horrifying, nightmarish force of power armour-clad spectres, rather than the mythic figures that the Imperium idolises as the Emperor's Angels of Death. Mystery and suspicion attach themselves to these dour and macabre warriors regardless of their true loyalties or intentions, and while they nominally serve on behalf of the Imperium, they prefer to operate independently, shunning all brotherhood of their fellow Adeptus Astartes Chapters. The reason for such insular tendencies is unknown, though some believe they are attempting to atone for some great sin committed in their past, and therefore, hide their shame until they can redeem themselves in the eyes of the Emperor.
Graven Souls		The Graven Soul are bellicose Space Marine Chapter whose terror tactics has earned these notorious Astartes a fell reputation across the width and breadth of the Imperium. They were created during the mysterious 13^th Founding, the so-called 'Dark Founding', due to the scarcity of any information on this particular Founding or how many Chapters were created at that time. To add to this Chapter's mystery, it is unknown from which genetic lineage they are descended from though they claim to be from the White Scars. Of all the Chapters of the Adeptus Astartes, none exemplifies the virtues of strict self-control more than the Graven Soul. The Graven Soul Chapter culture is one that is very wary of the idea of martial glory or honour, and prefers instead to emphasise pragmatism, adaptability and completion of the mission over all other concerns.
Gray Hussars		The Gray Hussars is a Loyalist, Codex-divergent Space Marine Chapter from the 26^th Founding. They descend from the gene-line of Rogal Dorn, Primarch of the stoic Imperial Fists. This Chapter unlike other Imperial Fists successors, doesn't associate themselves with the parent chapter, most of the founding officers being drawn from the zealous Black Templars Chapter and inherited many traditions from their Progenitors. The Gray Hussars prefer mobility, operating a large Astartes Fleet that is continuously enlarged which it operates from without a homeworld.
Great Bears		A Successor Chapter of the heroic Blood Angels the Great Bears was created during the 8^th Founding, which allegedly occurred during the mid-M34. This Founding was undertaken amid the dark times of the Nova Terra Interregnum, when the Imperium of Man had been split into twin interstellar empires. This Chapter has wandered far from the blood-theme of their Progenitors and their fellow Successor Chapters of the Blood. Taking on the symbol of the savage bears of their home planet, the Great Bears hail from a frigid, freezing planet near the Twin Stars of Ursa Major and Minor. Hardy and strong, they will weather any blizzard while unleashing a torrent of firepower against their enemies as they close in for the kill.
Grecians		The Grecians, known to themselves as Hellenes, were a loyalist semi Codex-compliant Chapter of the Adeptus Astartes created during an unknown founding, although extant records indicate they were suspected to have been founded during the 25th 'Bastion' Founding. The identity of their Primarch was also unknown, with knowledge being lost to the Chapter after an invasion of their homeworld. Created by the High Lords of Terra with the express purpose of guarding the Greater Grecian Sector in the Segmentum Pacificus, a task they had attempted to maintain with utmost priority. However, this stance did lead to other Chapters accusing the Grecians of ignoring greater threats to the wider Imperium. The Chapter predominantly spoke the language of its homeworld, Grecia, known as Grecian to the wider Imperium, as well as adopting Grecian numerals instead of the standard Gothic. The Chapter has been declared extinct following the destruction of their homeworld and the loss of every member.
Grey Gorgons		The Grey Gorgons are a formerly Loyalist Success Chapter created from the genetic heritage of the stoic and unforgiving Iron Hands. Created sometime late-M40 during the 25^th Founding. For over thousand years, the Grey Gorgons carved their own legends in the annals of the Imperium's history, winning several notable victories and taken part in numerous campaigns and Imperial Crusades. Unfortunately, their meteoric rise of this once-heroic Chapter came to a crashing halt when they became corrupted by the insidious influence of Chaos sometime in the early 900s-M41, during their participation in the Centurion War. As a result the Grey Gorgons Chapter, now renamed the Bringers of Change, found themselves declared Renegades by the High Lords of Terra. (Exommunicate Traitoris)
Grey Hounds		The Grey Hounds are a Loyalist successor chapter created from the gene-seed of the White Scars during the 21^st 'Cursed' Founding. Like many Chapters created during this ill-fated Founding, the Grey Hounds have also suffered unforeseen genetic idiosyncrasies. Almost nothing is known about this Chapter in official Imperial records, save that they share their forefather's battle lust and aggressive style of lightning warfare. Isolationist in their tendencies, the Grey Hounds will fight readily enough alongside other Imperial forces, however they remain aloof, preferring to keep their own counsel, and exchange only what battlefield intelligence they deem worthy of sharing in order to prosecute their campaigns.
Grey Orphans		The Grey Orphans are a Loyalist, non-Codex compliant Space Marine Chapter of unknown lineage, founded in 945.M36 during the 21^st Founding, also known as the "Cursed Founding". They were explicitly created to protect the Segmentum Tempestus from the continuous raids and uprising of Chaos Cultists. They are a Chapter of Space Marines that differs completely from the precepts of the Codex Astartes.
Grey Steeds		The Grey Steeds are a semi-Codex compliant Successor Chapter created during the 23^rd Founding, the so-called 'Sentinel Founding', from the proud lineage of the Ultramarines. This Chapter is stationed on the planet of Grassia, located in the Laanah Sector in the Segmentun Pacificus. These Astartes are known to employ mainly hit-and-run tactics in combat, while riding their genetically enhanced steeds, descendants of their worlds own original fauna. They are also well known for being one of the few, if not the only chapter of Space Marines to not possess a fortress-monastery, on purpose. Instead, while in their homeworld, the warriors of this order live a nomadic lifestyle similar to that of the planet's population. When the Steeds are needed outside their homeworld, they will rely on the Imperial Navy to provide the means of transportation to the order and their favored animals. In battle, they are fierce yet swift fighters, striking where the enemy suffers the most. Although able to fight alongside their cousin chapters and other imperial forces, these grey riders would rather handle the battle on their own, as to better maneuver the equines without ally interference.
Grey Wolves		The Grey Wolves are a Successor Chapter of the Space Wolves created during the Ultima Founding, consisting entirely of Primaris Space Marines. In their short history they have gone from bloodthirsty killers to being pushed to the brink of treachery, fighting against their own heretical brothers, but have held on to themselves with little more than their bitter hatred at those that have betrayed them and in the end their loyalty to the Emperor and the Imperium of Man.
Greyhorns		The Greyhorns ('Cornibus Griseo' in High Gothic) are a successor Chapter of the Rampagers and through them of the proud and savage White Scars from the 22^nd Founding. After the total freezing of Klondika II, their homeworld, the Chapter become fleet-based and adopted a nomadic pattern approach roaming between Segmentum Tempestus and Segmentum Ultima. Renowned for their 'humanity', the Chapter lost a great of its numbers after this characterstic of theirs was exploided by enemy forces, reduced to less then half ot its total power, the Greyhorns continues their roaming journey in the void, slowly rebuilding and learning new ways of warfare and approaches to better suite and conserve their numbers.
Greymanes		The Greymanes are a loyalist Ultima Founding Successor Chapter comprised entirely of Primaris Space Marines, descended from the lineage of the Vlkya Fenryka - the feral Space Wolves. Proud and noble, they place a great emphasis on individual skill at arms and valor in battle. They are, in turn, highly individualistic. As with their parent chapter, this sometimes leads to tension with Imperial authorities. Nonetheless, the chapter remains steadfast in its loyalty to the Imperial cause.
Guardians of Osiris		The Guardians of Osiris is a Loyalist Space Marine Chapter created during the 21^st "Cursed" Founding; the Chapter was censored by the Inquisition not long after their Founding, as the Adeptus Mechanicus had attempted to create Astartes with incredible resistance and durability. The skin of the Astartes from the Guardians of Osiris have a incredible endurance, making them perfect for battles were they are in the front lines, but the Chapter was affected by an unforeseen genetic idiosyncrasy, a genetic curse they called the 'Vali Rage'. The Guardians of Osiris are also notable for their specialisation in fortifications and defensive tactics, and are normally seen patrolling the Dunes sub-sector located in the Ultima Segmentum.
Guilliman's Rifles		The Guilliman's Rifles is a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines created from the lineage of the Ultramarines and raised during the Ultima Founding of 999.M41. Even though they are descended from the Ultramarines, they do not follow the Codex Astartes. The Chapter have chosen to specialize themselves exclusively in ranged warfare and consist solely of Intercessors, clad in Gravis Armour and armed with Heavy Bolt Rifles and use a multitude of different and unique bolter ammunition.
Gulf Hawks		The Gulf Hawks are a loyalist Codex-compliant Successor Chapter created from the proud lineage of the vaunted Ultramarines during the 22^nd Founding that occurred in M37. They proudly maintain their stoic heritage of the long lost Terran civilization of Merica. The Gulf Hawks were created to fulfill the needs of a specialist armoured/air-to-ground assault Space Marine Chapter, to counter the myriad threats of the Eastern Fringe - from the malevolent Forces of Chaos that reside within the warp anomaly known as the Maelstorm, to the deadly encroaching Tyranid Hive Fleets and endless Ork fleets that terrorize the Ultima Segmentum. Being successors of the well-organized and highly venerated Scions of Guilliman, the Gulf Hawks are experts in ranged warfare, armoured assault, and air-to-ground strikes. Gulf Hawks Astartes are known for their extensive use of highly accurate boltguns - the Mark VIII 'Colt' Pattern Bolter, as well as possessing a large quantity of Predator Annihilator and Horus Heresy-era Storm Eagle gunships.

Haietlik		The Haietlik are a Loyalist Adeptus Astartes Chapter created during the 23^rd 'Sentinel' Founding, comprised of both Firstborn and Primaris Space Marines. The Haietlik are semi-Codex compliant chapter that focuses on close-quarters battle and fighting in combined arms warfare alongside the Astra Militarum. They hail from the planet of Tac'am in the Segmentum Pacificus.
Halo Knights		The Halo Knights are a 3^rd Founding Loyalist Space Marine Chapter, claiming descent from the XVIII^th Legion of old. They are a venerable and honourable successor of the Salamanders, showcasing all the qualities of the sons of Vulkan, along with their love for flame and melta weaponry. In recent years, they have fought harder than ever before, driving back the darkness of M41.
Halo Templars		The Halo Templars is a Loyalist Space Marine Chapter of the Adeptus Astartes. A mysterious and aloof Chapter, it is unknown what Founding they were created of from what genetic lineage they are descended from. However, due to their secretive ways, many Imperial scholars believe they are descended from none other than the ancient Dark Angels. Some detractors believe that not is all that it seems and have made accusations that the Halo Templars are not descended from one of the original nine Loyalist First Founding Chapters, but are in fact, descended from the lineage of the Arch-Traitor himself - Horus Lupercal! However, the Halo Templars vehemently deny such accusations, pointing to their long list of victories obtained for the glory of the Emperor during their long millennia of service to the Imperium.
Harvesters		The Harvesters is a loyalist Space Marine Chapter created during the recent Ultima Founding from the ancient and aloof Dark Angels. Since its inception, this Chapter has garnered a reputation for its cold calculating approach to waging wars. More so than in other chapters the life of each battle-brother is considered secondary to his duty. Carrying out targeted strikes, abductions, and assassinations in the various sectors. This astartes chapter earned a fearsome reputation for their ability to get behind enemy lines and dismantle the command structure. Their mastery to infiltrate undetected and their dedication to their duties make them highly effective warriors.
Heart Rippers		A strange and unnerving Chapter, the Heart Rippers represent some of the darker aspects of the Sanguine Brotherhood. Born during the 21^st 'Cursed Founding' and descended from the Blood Angels, the Heart Rippers are Astartes bathed in blood, doomed to live blighted by suspicion. Hailing from the world of Bhairava, the Heart Rippers are violent, bloodthirsty warriors, masters of terror and devastation these ominous Marines are devoutly loyal to the God-Emperor of Mankind. Amongst the descendants of Sanguinius, the Devourers of Bhairava will never truly be accepted, their aberrant beliefs, disturbing methods and unsettling serenity making them live as eternal outcasts.
Hearthkeepers		The Hearthkeepers are a Loyalist Space Marine Chapter of the Adeptus Astartes descendant from Leman Russ and were created during the Ultima Founding which saw the emergence of the Primaris Space Marines. This chapter is based deep in the space occupied by the Necrons to the solar southwest of Baal and bordering close to the Great Rift. The Hearthkeepers are known for their penchant for seeking the most tumultuous battlefields they can find and have been commended for their stubborn nature in such engagements; engagements ranging from a time when they acted as bait to lure a millions-strong Khornate cult to their total destruction, to the time when they purposefully built their Fortress-Monastery upon a world in the same system as a small Necron Tomb World to enable the chapter to launch persistent attacks against it until its destruction.
Hellhounds		The Hellhounds are a Loyalist Chapter of the Adeptus Astartes created in 398.M34 as part of the 7^th Founding. Descended from the lineage of the stoic and merciless Iron Hands, they were created as a Crusading Chapter to bring light of the Emperor to the darkest corners of the galaxy. Highly mechanised, the Chapter maintains a large pool of armoured vehicles. Following their creation, this Chapter was a fleet-based Chapter for the first millennia of their existence. They roamed the galaxy fighting the enemies of the Imperium wherever they found them. The benefits of being a highly mobile strike force were threefold: to actively engage the enemies of humanity, to ensure the Chapter had a thorough understanding of the Imperium's enemies and to search the battlefields of the galaxy for any and all salvageable equipment, vehicles (especially tanks) and potential Standard Template Constructs (STCs). Considered by many to be a stalwart and utterly dependable chapter, the Hellhounds rarely refuse a request for aid, which has gained them many allies over the millennia of their existence.
Heralds of Ash		The Heralds of Ash are a Loyalist Space Marine Chapter of the Adeptus Astartes created during the 6^th Founding, which occurred sometime during the latter years of M33. Suspected of being created from the lineage of the heroic Blood Angels, the Heralds of Ash were one of several Chapter founded in the wake of the notable event known as 'The Year of Ghosts', when the Imperium was beset by extreme Warp activity and daemonic incursions. Only when the honoured dead rose up from their graves to drive back the terrors of the warp that the heart of the Imperium just barely managed to survive. Following this event the High Lords of Terra authorised the raising of a new Founding to help bring about stability and law back to those imperilled worlds that still suffered in the iron-grip of those who followed the Dark Gods.
Heralds of the Storm		The Heralds of the Storm, or Storm Heralds, are a 25^th 'Bastion' Founding Successor Chapter of the honored Penitent Knights Chapter. Created during M40, the Heralds are a stalwart Crusading Chapter, almost always bringing the Emperor's benedictions to the uncountable battlezones across the Imperium. No battle is too humble nor too indomitable for the Heralds to hesitate in deploying an appropriate response to an enemy of mankind. Being descendants of the Penitent Knights, the Heralds have inherited an incredibly monastic culture, looking to the omens of the God-Emperor to guide them in times of struggle or sorrow, but they also share in the shame of the existence of the Crow's Children Chaos Warband and the mystery of the origin of their gene-seed. But where the Penitent Knights focus on the defense of their demesne of the Asteria Sub-sector, the Heralds of the Storm believe in earning their atonement with relentless victory in the Emperor's name.
Hochmeister		The Hochmeister are a semi-Codex adherent Space Marine Chapter. Founded during the 7^th Founding with success. They possess even for an Astartes a exceptional robust body and defense against the Chaos. Rumors surround them being not a classic Space Marines. During an investigation the Inquisition and the Ordo Theoreticus found reasons to believe in a very mixed gene-seed. That would explain a quit high mutation rate. Most are just minor or can be prevented. But the transformation of somebody in a Space Marine of this chapter need even more experienced hands as in another chapter. Regardless of the rumors they are for their treatment of civilians and character quite popular.
Holy Hospitallers		The Holy Hospitallers are an ancient Crusading Chapter descended from the zealous Black Templars. They are extremely religious and fervently worship the God-Emperor with their every act. They also are firm believers in protecting the weak and aiding the less fortunate. All Battle-Brothers are expected to receive apothecary training and must be a certified apothecary before advancing to the rank of Preceptor or higher. Their holy mission is to provide aid and protection to Imperial pilgrims on their way to Terra through dangerous space. Typically the Hospitallers handle the escorting of the pilgrim fleets themselves and allow the Commanderies (crusading Battle Companies), usually with a Preceptory or Bailiwick attached, to bring medical aid to any planets in need that they come across on their trek.
Honour Mauls		The Honour Mauls are a fleet-based Successor Chapter of the Excoriators. They were originally created as an experiment during the ill-fated 21^st 'Cursed' Founding to study the effects of genetic modifications made on another Primarch's gene-line, in an effort to cure the Excoriators' mutation. The attempt was unsuccessful but created extremely resilient Astartes with powerful physiques.
Host of Aiakides		The Host of Aiakides is a Fourth Founding Space Marine Chapter of Rogal Dorn's lineage, created when another Imperial Fist Successor Chapter, the Phrygian Knights, as with all chapters that were alive by then, was ordered to supply a portion of their veterans to found a new Chapter in the aftermath of the War of the Beast. Warder Peithon of the Phrygian Knights chose his Hetairos Aiakides and his Astartes to be the leaders of this new force, henceforth named as Host of Aiakides. A Fleet-based Chapter, the Aiakidoi have since then taken to the stars and continuously battled the enemies of mankind.
Hounds Mortalis		The Hounds Mortalis are a ferocious and bellicose Loyalist Space Marine Chapter created during an Unknown Founding sometime before M36 from unknown lineage. They are notable for their preference for melee combat and ferocity in battle, charging their foes in an unrelenting and unstoppable charge, rending them limb-from-limb in a hail of blood and gore. Little is known of the history of this obscure Chapter, save at some point they destroyed much of their Chapter history and took a vow of silence. Their home world was destroyed and the Hounds became a fleet-based Chapter, forever after plying the space lanes of Ultima Segmentum and protecting Imperial worlds from various threats that might assail them.
Hounds of Kerberos		The Hounds of Kerberos are a Space Marine Chapter whose name has long been a byword for carnage and devastation. Their dichotomous nature manifests in the form of their savage tactics and brutal efficiency which is counteracted by their iron-bound discipline. Their namesake is derived from the creature of ancient Grecian mythology - the gigantic, three-headed hound of Haides, which guarded the gates of the underworld and prevented the escape of the shades of the dead - an apt appellation, as this Chapter continuously guards the Imperium of Man from the myriad of enemies that threaten Mankind.
Howling Wolves		The Howling Wolves are a Loyalist Space Marine Chapter who were formed during the 11^th Founding in 975.M35, with the purpose of stabilising the Imperium's borders during the Nova Terra Interregnum. They are currently deployed wherever they are needed most. It is unknown from whom they drew their gene-seed from.
Hunters Vigilant		The Hunters Vigilant are a successor of the venerable Dark angels created in the 9th founding.They are a dark and mysterious chapter keen to keep their secrets away from all. The Hunters Vigilant are expert trackers and are able to survive for years alone without backup or help.The Hunt vigilant have a deep burning hatred for chaos as their 5th company was once devastated by a Plague Marine ambush while pacifying a planet into Imperial compliance.This lead to the Hunters Vigilant having a deep mistrust for those they saw as being susceptible to the ruinous powers of chaos.
Hurricane Blades		The Hurricane Blades are a Codex non-compliant, fleet-based Iron Hands Successor Chapter created during the mysterious 13^th "Dark" Founding. They were created to serve alongside the Imperial Navy to help patrol vital shipping lanes and augment their allies during void warfare with enemy fleets such as the nefarious Drukhari and the Forces of Chaos. Recently, the Chapter lost most of their Firstborn Space Marines and fleet following the opening of the Great Rift.
Hyenas of Caliban		The Hyenas of Caliban are a Dark Angels Successor Chapter based within the Ultima Segmentum. Created during the mysterious 13^th Founding, the so-called 'Dark Founding' sometime during M35, this chapter has continued the martial tradition of honour, cunning, and chivalry as well as displaying a strong desire to hunt the Fallen, the traitorous Dark Angels that stain the honour of their beloved primarch. This Chapter is known to utilise more Deathwing Knights and Primaris Hellblasters more than any of their fellow Unforgiven Chapters.

Ice Dragons		The Ice Dragons are an unconfirmed and unacknowledged Salamanders' Successor Chapter created during the tragic 21^st Founding, also known as the 'Cursed Founding', which occurred in 991.M35, on the cusp of M36, shortly before the start of the Age of Apostasy. Initially, the Astartes of this Chapter only suffered cosmetic, physical changes such as distinct albinism. But soon they developed other unexpected, and much more serious, genetic idiosyncrasies - especially the peculiar mutation which necessitated the use of specially-modified power armour due to the Ice Dragons' inability to survive temperatures exceeding sub-zero.
Icebound Leviathans		The Icebound Leviathans are a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines. This White Scars Successor Chapter was established during the Ultima Founding in 999.M41. Similar to their progenitor chapter, the Icebound Leviathans are often used as forerunners to the main bulk of the Imperium's forces, sent to the most inhospitable parts of space to scout out new planets and expand the reach of the Emperor's light. As they operate on the fringes of the Imperium, they frequently encounter new enemies who hide in the shadows.
Icebound Sons		The Icebound Sons are a ferocious Loyalist Successor Chapter created from the lineage of the heroic Ultramarines. This Chapter was created during the mysterious 13^th Founding, the so-called 'Dark Founding', which occurred in M36. There is very little information about the Chapters created during this time. The Icebound Sons were created as a permanent standing force in the Rivia System, located in the Calixis Sector in the Segmentum Obscurus. Stationed upon the ice world of Sylence, the Icebound Sons stand guard as permanent sentinels against invading Forces of Chaos within the sector. This has earned them the eternal gratitude of the local populace and the moniker, 'The Sons of Sylence'.
Ignitors		The Ignitors are an ancient Loyalist Successor Chapter created during the 3^rd Founding, claiming lineage from the proud and heroic Salamanders. The Ignitors are known for taking to the battlefield bearing a plethora of flamer weapons. Preceding their fiery assaults with barrages of incendiary missiles, they hurl themselves at the charred, bewildered foe even before the flames have had a chance to gutter out. The Ignitors make their home upon the volcanic world of Accatrix, a planet located in the Ultima Segmentum, not far from the notable Imperial world of Elysia in the Segmentum Solar.
Illuminators		The Illuminators are an 8^th Founding Successor Chapter of the Raven Guard. Following a unique structure of 100 Deployments instead of traditional companies, the Illuminators can be found all across the Imperium's myriad battlefields in small teams, supporting other Imperial forces. Their Fortress-Monastery is a captured asteroid in orbit around the Death World Nullepart, fashioned into the shape of a giant head. As the oldest chapter in the Caedis Sector, The Illuminators have guarded its people for millennia alongside their allies in the Blue Flames, Steel Tempests and Jade Paladins chapers and have welcomed the Primaris Marines with open arms. Recently though, it was discovered that the Chapter was hiding a Slaaneshi cult, one which even spread to their own Chapter Master. While the cult was successfully destroyed, the Illuminators now work to atone for the damage dealt by their heretical brethren.
Immortals		The Immortals are a semi-Codex compliant Loyalist Chapter of the Adeptus Astartes hailing from the Eighth Founding in the middle to late stages of M35 and descended from the bloodline of the Blood Angels. These ill-understood but noble sons of Sanguinius have fought the enemies of man with a tenacity few of their peers could match, their extensive roll of battle honours reflecting that. Having proven themselves as staunch and stoic scions of their Primarch despite their isolationist tendencies, the Immortals have been commended by their parent chapter on several occasions. The Immortals maintain bonds of loyalty with their progenitors and the majority of their successor kin irrespective of the otherness some of their brother chapters might feel for them. However, following the Devastation of Baal, they have been increasingly distant largely due to their posting in the Avestan Satrapy far out into the Eastern Fringes.
Impalers		The Impalers are a notorious Successor Chapter created from the lineage of the proud and noble Blood Angels during an Unknown Founding. However, extant records indicate, based on eye-witness accounts and circumstantial evidence, that this Chapter was perhaps one of the many ill-fated Chapters created during the lamentable 21^st Founding, the so-called 'Cursed' Founding. This Chapter has displayed the worrying traits of an unnatural craving for blood and an insatiable drive to enact retribution against those that dared turn from the light of the Emperor - often in ways both horrifying and extremely more barbaric, as time went on. The preferred method of punishment utilised by these unforgiving Astartes against those that transgressed against the rightful rule of the Emperor was impalement, thus earning this bellicose and savage Chapter the appropriate moniker they would forever after be known and judged by - 'Impalers'. The resulting brutality often enacted during one of their campaigns has led to their being investigated on a number of occasions on charges of heresy and corruption by the Inquisition, but they have been cleared of suspicion, for the time being.
Imperators		The Imperators are a Codex-compliant Space Marine Chapter in the 41st Millennium. They were created during the Third Founding when the Space Marine Legions were broken down into smaller formations, known as Chapters. The newly incepted Imperators Chapter was created from the Ultramarines Legion. The Chapters of this Founding were created in order to replenish the power and might of the Imperium during uncertain times. The Imperators are masters at assault warfare, specializing in breaking down enemy positions via force and wit. They are loyal to the Imperium, but are often dismissive of outside interference in Chapter's affairs, at the dismay of Inquisitors and Imperial allies alike.
Imperial Angels		The Imperial Angels are a non-Codex compliant Chapter of the Adeptus Astartes created during the 22^nd Founding as successors of the Raven Guard. As a conservative return to traditional chapter development following the maligned 21^st 'Cursed' Founding. As a chapter meant to buffer against threats that come from the wild space to the galactic north of the Eye of Terror, the Imperial Angels specialize in small-unit operations, covering a large area of space with fire teams that rarely number greater than five, pre-empting hostile incursions and bases before they become a problem for the systems they are charged with protecting. They operate far from usual logistics, and use the independent nature of an Astartes to its fullest. Another quirk of the Imperial Angels is their tendency to second their marines, not just to other chapters of the same lineage, but to those of other lineages as well.
Imperial Brothers of the Sword		The Imperial Brothers of the Sword are a loyalist Adeptus Astartes Chapter, coming from the 23^rd 'Sentinel' Founding. Most unusual for a Chapter of this particular Founding is that this Chapter's gene-seed appears to be 'chimeric' - that is, somehow mixed - as it possesses genetic markers from both the the venerable and honoured Ultramarines and the stalwart Imperial Fists. The reasons for why, and whom, had a hand in the Chapter's creation, as well as their intent when they decided to mix the gene-seed of these two dedicated and heroic Loyalist First Chapters, has been lost to the ages. Although somewhat Codex-divergent, the Imperial Brothers of the Sword still abide by many of the rules and guidelines of the Codex Astartes. Though once a very isolationist Chapter that only stayed within their system to defend it, the Chapter has recently began to spread themselves out and help the surrounding sub-sector, and even to the sector that they reside in, within the Segmentum Pacificus.
Imperial Fiends	Pict-File Unavailable	The Imperial Fiends are a loyalist Chapter descended from the noble lineage of the angelic Primarch Sanguinius and the Blood Angels. Created during the 22^nd Founding, they are both estranged and despised by their progenitors, forced to make their own way in an uncaring galaxy, contemptuous of the thoughts of their peers. Friendly and approachable, kind and charitable, their acts of compassion and kindness are famed throughout the Imperium. Considered paragons of virtue, defenders of Mankind and heroes untold, they are the very pinnacle of the Emperor's ambitions and dreams for his enhanced Astartes. However, behind this facade of purity and righteousness lies a dark secret. Despite their reputation as a Chapter that epitomises the best traits of their genetic forebears, in reality, the Imperial Fiends harbour the worst excesses due to the inherent "Twin Flaws" of their bloodline. Within the souls of each of these Astartes lies a true creature of rage and blood-soaked madness, which can only be kept in check through ritual sacrifice and the mass consumption of blood. This 'salvation' has caused their own progenitors to turn their back on the darkly-tained Chapter, whom look upon their distant kin with abject disgust. Should this secret become known to the wider Imperium it would threaten the very existence of this self-righteous Chapter and would more than likely see them cast from the light of the Emperor.
Imperial Ravens		The Imperial Ravens are a Loyalist Space Marine Chapter created during an Unknown Founding and of uncertain lineage. They are known for being conservative in nature and most unusual for a Chapter of Adeptus Astartes, are zealous adherents of the Imperial Creed, believing in the Emperor's divinity and Mankind's manifest destiny to rule over the known galaxy. Wherever their assignments take them, the Astartes of this Chapter are known for their ostentatious display of devotion through extensive use of purity seals, Imperial Aquila pendants and prayer scrolls attached to their battle-plate, chanting songs of devotion and prayer, even in the heart of the most fiercest battles.
Imperial Sentinels		The Imperials Sentinels are 3^rd Founding successors of the formerly Seventh Legion, the Imperial Fists, and their Primarch Rogal Dorn. For ten millennia this fleet-based chapter has sailed the dark void of space, watching and waiting for the foes of the Imperium to show their faces. They remember the Imperium as the Emperor had intended, and who is responsible for the death of that dream. They are black armored avengers that stand between the Imperium and those who would see it destroyed.
Imperial Wardens		The Imperial Wardens is a Loyalist, semi-Codex compliant, Space Marine Chapter alleged to be ancient born from either the Second or Third Founding. The Imperial Wardens is a fleet-based chapter that follows a rare fusion between Crusade and Pilgrim patrol patterns across the Imperium. As they believe themselves to be the "Red Right Hand" of the Emperor, it's their right to patrol the galaxy in search for enemies, often boasting to have been at every corner of the Emperor's domain. The Chapter is known for its almost monastic behavior, from their recognizance of the Imperial cult to their adherent of the Imperial Creed, characterized for their intense reflection and study of the teachings of the Emperor and their Primarch Rogal Dorn. This by itself compels the Wardens to fanatically hunt and burn down any trace of heresy or betrayal against the Imperium, especially against the Forces of Chaos.
Imperius Ravagers		Known also as the 'Headsmen of Charopós', the Imperius Ravagers are a bloody-handed and bellicose Chapter created from the honourable Ultramarines during the 2^nd Founding in 021.M32. The initial cadre of this newly formed Chapter was made up of particularly hate-filled, bellicose Astartes - many of which survived the horrors of the Calth Atrocity and the subsequent Underworld War during the Horus Heresy. Led by their unforgiving and darkly-famed commander, Bruticus Kratos, this ferocious Chapter quickly garnered a fell reputation as both savage and unforgiving, wreaking terrible slaughter on those who dared to oppose Imperial rule. Since that time, this bellicose Chapter has continued to defend the sovereign realm of the Emperor and bring swift death to those who dare oppose His will.
Imperius Serpentes		The Imperius Serpentes are a mysterious Adeptus Astartes Chapter created during an Unknown Founding and of uncertain descent. Hailing from the sweltering heat of the jungle world of Tikal, these Astartes are as cold blooded as the massive serpents that haunt its depths but when roused they are terrible in their anger.
Incarnadines		The Incarnadines are a Loyalist Space Marine Chapter, created during the Ultima Founding as successors to the Argent Eagles. They therefore belong to the Chapters of the Blood, proud sons of the Great Angel Sanguinius. Plagued by the Twin-Flaws of the Blood Angels as well as the Blinding Radiance of the Argent Eagles, their brotherhood has endeavored to maintain a balance between the trinity curses of their gene-seed and uphold the legacy of their Primarch. Their warriors excel in the close quarters savagery of melee combat, tearing through their foes with swift sword strokes and disciplined bolter salvos. The sudden death delivered from on-high by their jump pack assaults may break even the strongest of defenses, for their hearts are filled with the eagerness of a Chapter that is young in more ways than one.
Incursors		The Incursors are a Loyalist, Codex-compliant Space Marine Chapter of unknown origins created during the 23^rd 'Sentinel' Founding. This fleet-based Chapter is an isolated and often reclusive Chapter that rarely works alongside other Imperial military forces or fellow Adeptus Astartes Chapters, and are often accused of being accused of being haughty or lacking in brotherhood. This is mainly due to their neverending Crusade to bring to light of the Emperor to the darkest corner of the galaxy, and despite their isolationist tendencies, this Chapter has continuously defended the realm of the Emperor of Mankind, earning a proud and enviable record of valour and service, comparable to other more senior Chapters.
Indominable Legion		The 'Legio Indomita' (known more commonly as the Indominable Legion) are an ancient Chapter descended from the Ultramarines of old, during the age when they marched as the 6^th Company of the Emperor's XIII^th Legion. However, the 6^th Company of that time, known as 'the Victorious' bear little resemblance to the brutal, grim-tempered warriors of the Indominable Legion of today. Masters in the prosecution of vicious wars of retribution, the Repentant Sons of Hadrian are remorseless and unforgiving warriors.
Inheritors of Caliban		The Inheritors of Caliban are a Codex-compliant Successor Chapter created during the Ultima Founding from the lineage of the venerable Dark Angels. Though a noble and pious Chapter, their name hides a dark secret few of them are privy to. The Inheritors of Caliban did not just inherit the genetic legacy of Lion El'Jonson, but the dark secrets hidden by the Dark Angels. As part of the Unforgiven, the Inheritors of Caliban are a shadowy and reclusive force indeed; seeking to redeem the First Legion's honour at any cost. In battle they favour strong fire lines and lightning assaults to slay a foe as quickly as possible before moving on to the next.
Invokers		The Invokers were a partially Codex-compliant Successor Chapter created from the lineage of the venerable Dark Angels during the 18^th Founding. They deviated significantly from the credos of the Codex Astartes due to their heritage and training as one of the Unforgiven, employing a Ravenwing and Deathwing formations as well as two additional scout companies due to an unprecedented close relationship to the Exorcists chapter prior to their fall from grace. The Invokers chosen path was one of daemon hunters and masters of the arcane, dealing with the Inquisition to a greater degree than most chapters and most certainly to a greater degree than their fellow Unforgiven. Since their fall from grace, they bolster their lessened numbers with fratricidal daemons and fanatical auxiliary forces of Malladictios now militant populace. (Excommunicate Traitoris)
Iron Beasts		The Iron Beasts are a recently created Ultima Founding Chapter consisting solely of Primaris Space Marines. Successors of the ruthless Space Wolves and carriers of Leman Russ's legacy, the Iron Beasts have shown excellent mastery of armoured and mechanized warfare, backed up by their quick moving attacks and ferocious talents in close combat.
Iron Bison		The Iron Bison are a semi-Codex compliant loyalist Space Marine Chapter of an Unknown Founding created from the lineage of the White Scars. They are currently engaged in a conflict with the Withered Hands Chaos Space Marines to reclaim several conquered worlds under the Iron Bison's protection. The Iron Bison Chapter primarily engages in hit-and-run and fast attack tactics, but a mutation in their gene-seed gives them a unique empathetic awareness of their environment, allowing them to sense enemies hidden behind cover or by unnatural means. This trait makes it excellent for scouting and hunting parties and it is not unheard of for a company of Iron Bisons to be sent out to find hidden enemy bases for other chapters or to stalk an enemy who has escaped the watchful eyes of the Imperium.
Iron Blood		The Iron Blood are a Loyalist Successor Chapter descended from the lineage of the stoic Iron Hands, one of the few bits of information still available to them about their past after near-crippling defeats that nearly destroyed their Chapter. Created during an Unknown Founding, the Iron Bloods are not even certain if they are direct successors or spawned from another Successor Chapter, though evidence points to the latter. At present the chapter has recently returned to full strength and is eager to prove themselves and erase past shames of defeat. They are commonly called the 'Iron Blooded'.
Iron Boars		The Iron Boars are a Loyalist Successor Chapter of the Adeptus Astartes that hails from unknown lineage. This Chapter was created during the mysterious 13^th Founding, the so-called "Dark Founding". Based on their habit of augmentation and closeness to the Adeptus Mechanicus it is assumed that the chapter is descended from the Iron Hands Primarch Ferrus Manus.
Iron Crows		The Iron Crows are a Loyalist Space Marine Successor Chapter created from the stoic and unforgiving Iron Hands. Chapter Lore states that they have existed in some capacity since the Horus Heresy, although Imperial records dispute this with the chapter being officially recorded after the War of the Beast. Despite these discrepancies, the chapter has served the Imperium well as a fleet-based chapter. Due to their long history as a fleet-based chapter and a belief in the Emporer's providence the Iron Crows consistently make do with little to no resources, instead, they rely on scavenging from wrecked ships in the void. They are usually in outdated and patchwork power armour with brutal scavenged and handmade weapons to supplement their well-worn standard equipment. The Chapter is known for its religious devotion to the Emperor of Mankind as a god similar to the zealous Black Templars Chapter, although they differ from the Imperial Creed in some aspects of their belief.
Iron Drakes		The Iron Drakes are a Loyalist Successor Chapter, which are known for their selflessness and for their absolute fearlessness in battle. The were allegedly derived from the heroic and brave lineage of the ancient Salamanders Chapter. They have a strong connection with humans and protect those that can't defend themselves. The Iron Drakes excel at the use of fire-based weaponry and close combat. In battle, they feel no fear and never run from the enemy until every innocent person is safe. The Chapter has a good connection with their Progenitors and proudly call themselves "Sons of Vulkan".
Iron Eagles		The Iron Eagles are a venerable Successor Chapter that hails from the proud lineage of the ancient XIX Legion – Raven Guard. They were created during the Second Founding which occurred in 021.M31, seven years after the near disastrous civil war known as the Horus Heresy which saw the Imperium brought to the edge of the abyss. The initial command cadre of the newly created Chapter drew heavily from the surviving Veterans of the Raven Guard, many having served both during the Great Crusade and Horus Heresy eras. Their esteemed ranks included several members who survived the cruel betrayal of the Drop Site Massacre of Isstvan V. Since their inception, the bellicose Iron Eagles have tirelessly prosecuted an eternal crusade of vengeance against the vile Traitor Legions across the width and breadth of the galaxy, prosecuting their bitter shadow war in order to gain a measure of vengeance on behalf of their Raven Guard ancestors.
Iron Flashes		The Iron Flashes are a loyal Sucessor Chapter of the wild and brave White Scars, created during the 5^th Founding. Where the White Scars are famous for their lightning assaults and rapid deployment of bikes and landspeeders, the Iron Flashes are famous for their deployment of heavy armours. They have perfected the use of armoured assaults much like their predecessors have with their deployment of bikes. Many enemies of humanity have learned to fear the armoured attacks of the Iron Flashes. Only a few half death enemies survived and could tell of this destructive storm of iron and steel.
Iron Gorgons		The Iron Gorgons are a Successor Chapter of the stoic and unforgiving Iron Hands. This Chapter, along with the Sanctors of Manus and the Templars of Iron, make up a triumvirate of 2^nd Founding Iron Hands' Successors, collectively known as the Frateris Firmitatis ("The Ironclad Brotherhood"). The Iron Gorgons were Founded from a portion of the Iron Hands Chapter's Voraag Clan - survivors from the infamous Dropsite Massacre of Isstvan V. This clan was comprised of aggressive, brutal and willfully petulant elements of the original X Legion, who refused to recognise the authority of the newly appointed Iron Council following the aftermath of the Horus Heresy. When the High Lords of Terra decreed the 2^nd Founding in 021.M31, the Iron Hands Chapter used this opportunity to purge themselves of this troublesome clan. Since that time, the Iron Gorgons Chapter have proven themselves as true Scions of Ferrus Manus, garnering a reputation as an unassailable and resolute Chapter of Space Marines.
Iron Guard		The Iron Guard is a Loyalist Successor Chapter of Adeptus Astartes created from the lineage of the stoic Imperial Fists during the 23^rd Founding, to so-called 'Sentinel Founding'. These Scions of Dorn are known for their extensive use of both regular and heavy bolter weaponry as well as their distinct lack of Assault Marines.
Iron Harbingers		The Iron Harbingers are a particularly grim and ruthless Successor Chapter that hails from the tragic legacy of the unforgiving Iron Hands. They were created in the wake of the tragic events of the Horus Heresy and the subsequent Great Scouring that ended in 021.M31, during the 2^nd Founding. The Iron Harbingers were founded from a portion of the Iron Hands' Clan Kadoran, one of the oldest Clan Companies of the Iron Hands Legion during the Great Crusade and Horus Heresy eras, which incorporated many of the Legion's Terrans. This clan was also notable for being masters of scientific and technical pursuits as well as being cunning practitioners of siege warfare and the oft-misunderstood arcana of Cybertheurgy. Following their inception the Iron Harbingers, along with the Iron Gorgons, Templars of Iron and the Iron Invictors, formed an unofficial quadrumvirate of other Iron Hands Successor Chapters created during this Founding, known as the Frateris Firmitatis ("Ironclad Brotherhood").
Iron Juggernauts		The Iron Juggernauts ('Implacabilis Ferrum' in High Gothic) are an ancient Successor Chapter from the proud and savage White Scars lineage of the ancient 2^nd Founding when the Legiones were splitted as dictated by the Codex Astartes, the Chapter builded for itself a grim reputation during the Great Scouring and their nomadic hunt for traitors before finally settle down to the world of Tundra within the Ogun System in early M32. The Iron Juggernauts, as well as their predecessors during the Great Crusade, wage war differently from the White Scars and their other scions. While their attacks remains swift and violent, their favourite way of deployment is dropping from the skyes to take the lives of the Imperium's enemies. The Chapter, also, take particular pride in their traditions, in the remembrance of the ancient stories of the Legiones and the Great Crusade and believe in the brotherhood between Astartes no matter the gene-lines.
Iron Myrmidons		The Iron Myrmidons are a mostly Codex-compliant Imperial Fists Successor Chapter from the 4^th Founding, after the disastrous War of the Beast, with a focus on Zone Mortalis combat & siege warfare. They are a proud and tenacious chapter, rarely devolving into savage or overly brutal conduct but instead are an unrelenting tide of adamantium & ceramite sending precise volleys of bolter fire into their foes while vehicles and heavy specialists move ahead.
Iron Prophets		The Iron Prophets are a Loyalist Primaris Successor Chapter of an unknown gene-seed created during the Ultima Founding. They are known for their shock and awe tactics and overwhelming forces they bring to bear. For the most part they have abandoned the Codex Astartes, only keeping to it's overall strength of 1,000 battle brothers. They are a fleet-based Chapter whom patrol up and down parts of the Great Rift.
Iron Purity		The Iron Purity are an ancient and stalwart Loyalist Successor Chapter created from the proud lineage of the Ultramarines, supposedly created as early as the 2^nd Founding, following the bloody civil war of the Horus Heresy and the subsequent Great Scouring. An honourable and dedicated Chapter, the Iron Purity have continuously fought the enemies of Mankind for ten millennia, standing as a bulwark between realm of the Emperor and the encroaching darkness of the Ruinous Powers.
Iron Retributors		The Iron Retributors are a loyalist Successor Chapter created from the lineage of the grim and unforgiving Iron Hands during the 10^th Founding sometime during mid-M35, created amid the dark times of the Nova Terra Interregnum, when the Imperium of Man had been split into twin interstellar empires. Posted just over the borders of the Segmentum Pacificus, the newly formed Chapter claimed the backwater feudal world of Geyron Prime. The Iron Retributors were created following the success of a single squad from Clan Raukaan Iron Hands led by Sergeant Flavius Byzantum following the successful purged of a massive space hulk from unknown xenos. The Chapter embraced the Codex Astartes without losing their long lost tradition as Sons of the Gorgon.
Iron Revenants		The Iron Revenants is a Loyalist Codex Astartes-compliant Space Marine Chapter. The Iron Revenants is a Successor Chapter of the stoic and unforgiving Iron Hands considered part of the Ultima Founding, although their original chapter records extend back to the troubled 36^th Milleniun, a time of great upheaval.
Iron Seraphs		The Iron Seraphs are a fleet-based Successor Chapter descended from the venerable Angels of Absolution, whom themselves are descended from the ancient and mysterious Dark Angels Chapter. This Chapter is comprised entirely of Primaris Space Marines, created during the most recent Ultima Founding. As a fleet-based Chapter, the Iron Seraphs are highly active at prosecuting the wars of the Imperium against the myriad of enemies of Mankind. Like their fellow Unforgiven Chapters, the Iron Seraphs are driven to prosecute the Dark Angels' secret war against The Fallen, and are more than willing to answer their progenitors' call to war in order to achieve their objectives.
Iron Sights		The Iron Sights are a Successor Chapter of the stoic and unforgiving Iron Hands. Created during the 9^th Founding, they are renowned throughout the Imperium for their extreme marksmanship and heavy firepower. Unlike many Space Marine Chapters they tend to eschew hand-to-hand combat, choosing instead to annihilate their enemies with devastating hails of bolts, plasma, and lascannon fire. While their lack of hand-to-hand combat estranges them from some chapters, such as the zealous Black Templars, it has allowed them to forge some mutually beneficial alliances with close combat oriented chapters such as the Angels of Rebirth.
Iron Spears		Hailing from the Death World of Ailinne, the Iron Spears (Hastae Ferrum in High Gothic and Gaith Airanna in Ailinnean) are are a Chapter of Space Marines with a long and proud history. They were created from the genetic lineage of the Storm Lords, whom themselves supposedly hail from the ancient White Scars. Operating from their fortress-monastery of Dunbairrche, the Iron Spears are deployed across the Segmentum Obscurus and Segmentum Ultima. The Chapter has been led by High Chieftain Fionn Cathair for nearly five centuries since his predecessor passing in 634.M41.
Iron Strategoi		The Iron Strategoi are a non-Codex compliant Ultima Founding Chapter, released from the stasis vaults of Archmagos Dominus Belisarius Cawl. Who led the Lord Regent Roboute Guilliman to believe this Chapter were sons of Ferrus Manus 'The Gorgon'. However, these staunch defenders of the Imperium know their real heritage, and keep the secret close to their chests, doing much to prevent those who have prying eyes like those of the Inquisition from discovering these truths until the time is right. Though supposedly successors of the Gorgon they are siege and heavy weapons specialists, as well as capable architects. These Marines are no strangers to fortifying locations and assisting destroyed worlds to rebuild their homes. Many of the Iron Strategoi have augmentations though not as many as their respected Iron Hands counterparts, they as well rely on a higher number of Techmarines and large amounts of heavy tanks such as the Astraeus Super-Heavy Tank.
Iron Templars		The Iron Templars are an ancient Chapter descended from the lineage of the venerable Dark Angels. Believed to have been created in 021.M31 during the Second Founding, the Iron Templars have continued to follow in the footsteps of their genetic forbears, to relentlessly hunt down every single Fallen Angel and force them to repent. Despite their secretive nature and dedication to seeking out the Fallen, the Iron Templars have garnered a reputation as an honourable and dedicated Chapter who fiercely protect their planetary system of Aquitaine against the gathering darkness from Chaos, xenos and the myriad threats that threaten the Imperium on all sides. As a Chapter steeped in the feudal traditions of its Chapter home world, the Iron Templars' doctrines, traditions, and organisation reflect their particular approach to prosecuting the Imperium's wars.
Iron Wardens		The Iron Wardens are Founded in late M35, partly due to the events of the Moirae Schism, which caused them to split from their progenitors - the stoic and unforgiving Iron Hands. While these outcasts would go on to prove themselves loyal as the Sons of Medusa, the Iron Wardens themselves would go to prove themselves as tactically brutal Space Marines. Like their forebears the Wardens have close a relationship with the Adeptus Mechanicus. This not only allows the chapter to use and maintain advanced weapons and vehicles but often the chapter will march alongside the Skitarii and other forces of Mars. This however leads the chapter to accept numerous missions from the Mechanicus often without questioning the orders given. This has lead to clashes with other parties - both chaos and xenos alike.
Ironclad Templars		The Ironclad Templars are a Loyalist 3^rd Founding Space Marines Chapter derived from the lineage of the stoic Imperial Fists but are more alike their sword brothers of the zealous Black Templars. The history of the chapter was lost during the First Defense of Aevis, where part of the chapters vaults was burned down by Drukhari Kabalite Warriors. The number of crusades the chapter have been on is unknown as the records where lost in the vault fire, but what is known is that somewhere fought alongside the Black Templars. The chapter is Codex Astartes-compliant, unlike their Black Templar brothers. The chapter has just under 1,000 Astartes.

Jackal Claws		The Jackal Claws are a semi-Codex compliant, rare Successor Chapter created during an Unknown Founding from the lineage of the stealthy and foreboding Raven Guard. This Chapter is notorious for their isolation and tendency to scavenge battlefields. They are also known for being respectable snipers and masters of stealth. Furthermore, they are noted for being incredibly distant from their progenitors and fellow successors, not due to circumstances of distance or duty, but out of distrust and resentment towards Corvus Corax for banishing their ancestors long ago.
Jade Knives		The Jades Knives are a Loyalist Successor Chapter created from the lineage of the proud and noble warrior, Primarch Jaghatai Khan of the wild and savage First Founding White Scars. This Chapter was created as one of several newly incepted Chapters during the 26^th Founding in 738.M41. The Jade Knives were created to stand as a bulwark against the new xenos presence in the Eastern Fringe of the Ultima Segmentum - the ever-expanding Tau Empire. Following the death of their first chapter master, the Chapter was torn in two, which resulted in an internecine conflict that nearly saw the Chapter destroyed before it had barely been able to make its mark in the annals of Imperial history. This destructive conflict resulted in the Chapter being torn in two, due to their divergent beliefs and differences in overall beliefs. This resulted in the formation of a Successor Chapter - the Jade Paladins. Despite this troubled era, the Jade Knives rose from the ashes of their near-destruction, and have continued to prove themselves as stalwart and dedicated defenders of the Imperium.
Jade Wyverns		The Jade Wyverns are a Loyalist Adeptus Astartes Chapter created during the Ultima Founding and comprised almost entirely of Primaris Space Marines succeeding from the Salamanders, Sons of Vulkan. Beginning as Greyshields among the Legions formed for the Indomitus Crusade, they were deployed via Torchbearer fleet to reinforce the Iron Wyverns, a Firstborn chapter in dire need of support. As events unfolded, however, they would form a new chapter entirely, believing the original to be lost to the catastrophes that marked the start of the 42^nd Millennium. The survivors of the Iron Wyverns would, fortunately, reappear and join with the Jade Wyverns, working to integrate the two "breeds" into one chapter. Tasked with bolstering the defenses of the Imperium Sanctus against the forces of the Ruinous Powers, and any other enemies of the Imperium, the Jade Wyverns seek to defend humanity, despite their misgivings about the present state of the Imperium and the galaxy at large.
Janus Marines		The Janus Marines are a Loyalist, semi-Codex compliant Space Marine Chapter created during the 21^st 'Cursed' Founding, and, as such, infamously bear a great Flaw within their gene-seed, resulting in mental and emotional changes that vary between expeditious, and occasional in each Marine, with both being too sporadic to predict. Due to this flaw, none claim them to be their progenitors, with some even outright despising them, the details of their lineage now being lost to time. Though they continue to serve the Imperium and Emperor in spite of their feelings towards them, they are not without their well-kept secrets, to the great annoyance of the Inquisition, serving to intensify their disdain for them. The Janus Marines loosely follow the Codex Astartes, bending it slightly or greatly depending on the rule itself. Their most notable acts were their involvements in the Age of Apostasy and the Badab War, the former due to most Space Marines simply minding their own business, and the latter for nearly splitting the Chapter in half.
Jomravens		The Jomravens are a loyalist chapter of Space Marines hailing from the gene-stock of Corvus Corvax that were created during the 13^th 'Dark' Founding, shrouding their history in mystery like most of the chapters of this shadowy founding. Masters of aerial and void warfare in all aspects, from long-ranged ship combat to savage boarding actions which they favor and excel at more than anything else, as well as things like line-breaking tactics and covert operations on planetary surfaces in support of allied forces. When not using subtle tactics they will often use a massed wave of drop pods and dropships to quickly reinforce covert forces inserted beforehand, or reversely warriors will be taken directly to a target via aerial vehicles following an initial wave of drop pods to counter any defensive points giving them trouble.
Judicators		The Judicators are an aloof and isolationist Successor Chapter created from the lineage of the ancient Dark Angels during an unknown Founding. Their origins have been purposely obfuscated, and their goals remain elusive to outsiders. However, the truth to the matter is much more complicated, as in actuality, the Judicators are an ancient Chapter created from a lost Second Founding Dark Angels Successor Chapter who were expunged following the unspoken period of Imperial history known as the Forgotten Wars in the middle centuries of M32. Following their inception, their subsequent fate and entire Chapter history were deliberately hidden from those outside the Dark Angels and their collective of Successor Chapters, known as the Unforgiven. The Judicators now operate independently away from the rest of the Imperium, and down the millennia, have become forgotten. However, their inherent duty to hunt the Fallen has not been relented.
Juggernauts		Born during the 21^st 'Cursed' Founding, the Juggernauts are often referred to as the 'Inviolable Tide' and, true to both their nickname and the name of their Chapter, the warriors of the Endless Crusade are a terrifying and seemingly numberless foe. Obstinate in the extreme, it is near impossible to dissuade a Juggernaut from their chosen course, come death or come the Emperor's personal command, they will never retreat, no sacrifice too great in their quest to eradicate the Master of Mankind's enemies.

Karaashi Arbiters		The Karaashi Arbiters are a non-Codex compliant Loyalist Successor Chapter created from the lineage of the stoic and unforgiving Iron Hands during the 11^th Founding. The chapter maintains a homeworld in the Finial Sector of the Segmentum Obscurus but is primarily fleet-based and is spread thinly across imperial space. They are little known to other Astartes Chapters but are widely respected within the Imperium's elite class and the Adeptus Arbites for their brutally efficient skill in quelling uprisings on imperial worlds. The Arbiters ruthlessly uphold and impose the law that they bring to a world, maintaining newfound stability with an iron fist.
Keepers of the Accord		The Keepers of the Accord is a Loyalist Chapter of the Adeptus Astartes shrouded in mystery and symbolism, thus worthy successors of the Dark Angels and their Primarch Lion El'Jonson. Presumably - like their forebears and brother Chapters, the Keepers are part of the Unforgiven - the brotherhood of Chapters that hunt the Fallen Angels. However, they are distant from their fellow Unforgiven, not because of a grudge or spite, but because of their creation. Despite the tactic approval of the High Lords of Terra the Chapter's creation, their inception is mired in classification and mystery. What is known is that the Keepers have always stood vigil over a wandering planetoid named "Thessalon" from a great space station acting as their Fortress Monastery of Caelestis Castellum. The Keepers of the Accord maintain a rather high number of Techmarines among their ranks, and thus have an impressive quantity of Land Raider patterns in their armory.
Kharonean Martyrs		The Kharonean Martyrs is a loyalist Chapter of the Adeptus Astartes, created during the 18^th Founding, though the exact date of their inception has been lost to the shifting tides of time. They belong to the gene-line of Lion El'Jonson, which makes them a part of the Unforgiven successors of the Dark Angels Legion. They are, for the most part, adherent to the structures of the Codex Astartes, though many of their methods are somewhat unorthodox when stood beside other Space Marine Chapters. On the field of battle, the Kharoneans Martyrs prefer to look their enemies in the eyes as they tear their bodies apart with the teeth of their chainswords and burn what remains in the purifying fires of their melta guns. As far as their beliefs are concerned, death is a personal affair that deserves due respect, for all brothers of the order see themselves as the ferrymen who carry the souls of the living, both saintly and foul, across the endless rivers of the afterlife. Whenever the Chapter comes to the aid of a beleaguered system or fights alongside other Imperial forces, they will demand compensation for the blood they shed. To replenish the high numbers of men, equipment, and other resources they expend, the officers of the Kharonean Martyrs will name a steep price to whoever possesses the means to pay them. It is merely their due reward, for a debt incurred through the sacrifice of Astartes lives, and so they feel little shame about taking what is rightfully theirs.
The Kin		The Kin are a courageous and savage chapter of the Adeptus Astartes. Founded during an Unknown Founding in M35 from the gene lineage of Roboute Guilliman. Originally a chapter devout to the Codex Astartes, the chapter has changed drastically since it's founding. They are experts in tracking, shock assault and close-quarters combat often taking their enemies by surprise and tearing them apart in mere moments.
Knight Paragons		The Knight Paragons are a loyalist semi-Codex compliant Space Marine Successor Chapter created from the lineage of the proud and glorious Salamanders during the late M41 and the Ultima Founding. They are a honorable and compassionate Chapter and believe that to protect the lives of the Emperor of Mankind's innocent subjects is one of their most important duties.
Knights Angelicus		The Knights Angelicus are a venerable chapter of the ancient Second Founding coming forth from the remains of the 50th Chapter of the noble Blood Angels. They are a proud and noble chapter that value the honor of brotherhood while also valuing the lives of their brothers as dictated by the Stygian Oath all members of the chapter take when they join the chapters ranks. It is upon these ideals and beliefs as written down in the oath that dictates the actions and choices taken by chapter members when it comes to their brothers.
Knights Celestial		The Knights Celestial are a Dark Angels Successor Chapter based within the Ultima Segmentum close to the infamous warp anomaly known as the Maelstorm. Created during the 13^th Founding, the so-called 'Dark Founding' sometime during M35, this chapter has continued the martial tradition of honour and chivalry as well as displaying a strong desire to slay the forces of the Immaterium - both Traitor Astartes and Daemons alike. The Chapter is known to possess ancient Chivalry Pattern Bikes more than any other chapters.
Knights Despoilers	Pict-File Unavailable	Created during the 26^th Founding, the Knights Despoilers were created as a Successor Chapter of the Red Crusaders, whose lineage is unknown. Striking from the void relentlessly and eager to punish the unworthy, the Knights Despoilers embody the fervent zeal of their foster chapter, the Red Crusaders. The Knights exploit these terror tactics to quickly discourage most opposition, being specialists in dealing with planetary rebellions and cultist uprisings.
Knights Seraphic		The Knights Seraphic are a Successor Chapter of the heroic Blood Angels, created during the 9^th Founding. This vexatious and mysterious Chapter were formally sanctioned by the High Lords of Terra for dabbling in dark rituals and having a penchant for tech-heresy. To atone for their crimes they were forced to embark upon a penitent crusade by Imperial authorities. Steeped in secrecy and accused of anti-Imperial sentiment, this Chapter of monastic esotericists wander the stars trying to piece together the history of their order.
Knights Triumphant		The Knights Triumphant are a Loyalist Successor Chapter created from the lineage of the ancient and secretive First Founding Dark Angels, and as such, this makes them one of many Chapters that make up the unofficial collective known as the Unforgiven. The Knights Triumphant were created during the 7^th Founding sometime during M34.
Knights of Argent		The Knights of Argent are a Loyalist Codex-divergent chapter of the Adeptus Astartes, they were founded sometime after the 2^nd Founding. They are currently situated on the civilized world of Ehre and operate in the Segmentum Ultima somewhere in the center of the sub-sector of Adamant. The chapter specializes in siege warfare and is renowned for its skills with the blade and in which honor is all.
Knights of Aryith		The Knights of Ayrith is a Loyalist Space Marine Chapter created during the ill-fated 21^st Founding, the so-called "Cursed Founding". They were supposedly created from the lineage of the heroic Blood Angels, characterised by their brutality and their radical vision of the Imperium. Despite several investigations into the Chapter's true lineage, their origins have never been definitively verified.
Knights of Death		The Knights of Death were founded after the War of the Beast. The first members came from the Salamanders. Their first campaign was to liberate the lost Unalium Sector from the Orks. The Knights of Death purged the bloodthirsty xenos. During this campaign, they saw many disloyalties. From it, they learned the value of loyalty, honour, courage and sacrifice and to appreciate life. By this campaign's conclusion, they learned the tactic of committing massive forces with the support of Imperial Guard regiments.
Knights of Eternity		The Knights of Eternity is a loyalist Space Marine Chapter that originated from the gene-seed of the Dark Angels. Born during the 23^rd 'Sentinel' Founding, the Knights of Eternity fight across the Imperium and the galaxy. The Knights of Eternity believe in 'Eternity' as a concept of their duty and believe that there is never an end to fighting the wars of the Emperor and see it as their duty to fight to the end of time itself. This belief leads the Chapter in thousands of war zones where they are outnumbered and outmanned and this belief brings that out the other side. The Knights of Eternity have earned their reputation as unwavering defenders of the Imperium, standing firm in the face of relentless foes and adhering to their creed of 'Eternity in Service'.
Knights of Guilliman		The Knights of Guilliman is a Loyalist Successor Chapter created during the 5^th Founding from the Novamarines and through them the Ultramarines. As expected from those of the Roboute Guilliman's blood, they are staunch adherents to the Codex Astartes and are often at odds with those who scorn it. Their homeworld is a feudal world very similar to the ancient Dark Angels' homeworld of Caliban. They were on a penitent crusade for siding with the Secessionists during the war known as the Cerberus Crusade. The Cerberus Crusade was fought in late M41 between the forces of the Imperium and Adeptus Mechanicus Secessionist forces under the rule of Magos Ovid Terrozant who seized control over several Forge Worlds and led an attempt to secede from the Imperium. The Knights of Guilliman were granted the Honour of rejoining the Imperium in 999 M.41 and have once again become one of its staunchest defenders.
Knights of Iscariot		The Knights of Iscariot are a 3^rd Founding Successor Chapter of the Dark Angels. Unlike most Astartes Chapters, the Knights of Iscariot worship the Emperor of Mankind as a genuine god. They are also known to be specialists in hunting down traitors, heretics, and daemons. The Chapter's faith and specialty have led them to form good relations with the Ecclesiarchy, the Ordo Malleus and the Ordo Hereticus. Despite their good reputation among the Ecclesiarchy and the Inquisition, the Knights of Iscariot are not immune to the dark and foreboding nature of their forebears. Despite their spectacular service record and abundance of religious zeal in the present, their past remains shrouded in mystery and contains many a dark secret.
Knights of Russ		The Knights of Russ are an Ultima Founding Space Marine Chapter comprised primarily of Primaris Space Marines. The Chapter has an altered Space Wolves gene-seed due to the fact that their Great Wolf, Ulrick Frostbane's gene-seed mutated due to unknown factors. Based on the plant Varneir located in the Varneir system, the Knights of Russ would claim the world as their homeworld during the Tyrean Crusade. The Knights of Russ alongside four other chapters, the soon to be Valkyries of Varnier, and Multiple Guard Regiments (including the 23^rd Ice Rangers Guard Regiment) would be ordered to the Tyrean sub-sector to capture the five solar systems and take of guarding the Warp Rift known as the Iron Maw at the center of the sub-sector.
Knights of Sanguinius		The Knights of Sanguinius are a fiercely loyal 25^th 'Bastion' Founding Space Marine Chapter created from the noble and proud sons of Sanguinius. They were born to defend the shrine world of Oleyuria in the Segmentum Obscurus and have done so since their birth. Already their name is sung throughout the northern Imperium, their first main actions in the Devastion of Baal Campaign. Here they fought like the Blood Angels themselves, striking fast with the fury and power of a thunder bolt. They earned the respect of many of their fellow brother Chapters and their genetic forebears. They, like a lot of the Blood Angels Successor Chapters, have strong ties with the Blood Angels and the other Chapters of the Blood.
Knights of Sol		The Knights of Sol are a Loyalist Space Marine Chapter from the 19^th Founding, descended from the Primarch Rogal Dorn and successor to the Black Templars Chapter, a proud heritage they strive to uphold with honor and courage, the Chapter constantly struggles against the forces of Traitor Legions and Chaos Daemons, and zealously defend their homeworld of Valium from the foul taint of Chaos. They are known for their proud Knightly culture and the great importance they give to honour, brotherhood and chivalry, as well as their disregard for combat vehicles and their preference for melee combat. Their pride works against them in many cases, specially when they refuse to hide their Chapter's Heraldry with camouflage.
Knights of Thunder		The Knights of Thunder, also known as the Thunder-kin, are a very young loyalist, Codex-compliant, Space Marine Chapter created from the gene-stock of the Imperial Fists and Black Templars during the 26^th Founding. They were introduced as part of a program to expand Space Marine protection over the Segmentum Tempestus, especially the Corribra Sector, from threats emanating from the Veiled Region. While once a fleet based chapter that patrolled the southern Segmentum Tempestus, the chapter was eventually given stewardship over the storm stricken world of Ukkonen and its moons. One characteristic that makes the Knights of Thunder stick out from its brother chapters is its veneration of the Emperor as a deity and his sons as angels. Despite this, the Knights still do their utmost to protect human lives, seeing them as equals in the eyes of the Emperor and thus worthy of respect and veneration.
Knights of the Anvil		The Knights of the Anvil, also known as the Anvilars, are a Loyalist Space Marine Chapter created during an Unknown Founding and are of uncertain lineage. Though their exact origins are unknown, they first appear in Imperial records as far back as M34. The Anvilars serves as one of the Hell Warders Chapters - a quintumvirate of five Space Marine Chapters - tasked to defend the Imperium against Chaos incursions from the 'Hellgates', the dual warp storms located in the Segmentum Solar which are located uncomfortably close to Holy Terra. The Anvilars are the only Chapter out of the five whose presence in Sector Occident Prime predates the First Hell Crusade.
Knights of the Fist		The Knights of the Fist are a crusading Successor Chapter descended from the proud lineage of the stoic Imperial Fists. Once known as the Knights of Caledon upon their inception, they formerly derived much of their doctrine from the example of the Black Templars, however, they have since developed their own direction, especially in the post-Tenebris era. The Chapter stands on the precipice of loyalty and apostasy. Following the resurrection of Guilliman, his appointment as Lord Regent, and the subsequent Indomitus Crusade, the Chapter's formerly Codex-sceptical outlook has become more extreme. The Chapter is now openly hostile to Guilliman and Ultramarines successors, but nonetheless professes its loyalty to the Emperor.
Knights of the Frost		The Knights of the Frost were created in the 10^th Founding in the mid 35^th Millennium in the H’Toh system on the edge of the Stygius Sector not far from the Mordian system. Whilst a successor of the White Scars, the Knights of the Frost have spent more time fighting in campaigns close to the Space Wolves.
Knights of the Lion		The Knights of the Lion are a loyalist Space Marine Chapter created during the 24^th Founding and are members of the Unforgiven of the Dark Angels. Sharing many similarities with their original chapter, the Knights were made to be extremely flexible and well-rounded, as well as Codex-compliant, at least on the surface for appearances. The one aspect where they do stand out is in close quarters combat, and even Knights who share specialties such as siege-warfare or armored assaults still excel at dueling and swordsmanship. Other than that, from the outside, the Knights of the Lion appear to be nothing more than honorable, devoted guardians.
Knights of the Throne		The Knights of the Throne, known in High Gothic as the 'Thronus Equites', were once a noble if somewhat young Successor Chapter created from the lineage of the heroic and stalwart Blood Angels. Cursed with an even higher decree of their angelic gene-sire's prognosticative abilities, the Chapter suffered from horrific visions of their fall, which showed them succumbing to one of their gene-line's twin genetic curses - the Red Thirst. However, through these prophetic visions they also saw the promise of their deliverance, which unfortunately proved false and led to the downfall of the doomed Chapter, as half of them fell to the unnatural rage and blood-seeking madness of those who follow the Chaos Blood God Khorne, and led to half the Chapter becoming the notorious Chaos Warband, the Angels of the Voracious Chalice. (Traitoris Perdita)
Knights of the Watch		The Knights of the Watch are not a standard Chapter but a fellowship of veteran Astartes who, inspired by the example of the loyalist Death Guard Battle-Captain Nathaniel Garro - Agentia Primus of Malcador the Sigillite - have left their Chapters to follow the path of Errantry, to seek out and destroy the enemies of the Emperor wherever they might be found.
Knights of Ultramar		The Knights of Ultramar are Loyalist Space Marine Chapter that is descended from the noble Templars of the Golden Dawn. They are amongst the most bravest and honourable Chapters in the entirety of the Imperium of Man, and were given the honour by the Ultramarines themselves to wear their symbol on their armour. Besides the Ultramarines themselves, they hold the Codex Astartes higher than almost any other Space Marine Chapter and are dogmatically loyal to the Imperium of Man and the memory of their Primarch Roboute Guilliman.
Knights of War		The Knights of War are a Loyalist 23^rd 'Sentinel' Founding and rare Successor Chapter of the highly venerated White Scars. The Knights of War are notable for their duality of character - being a highly aggressive and bellicose Chapter which are brutal to their foes almost to the point of savagery - but are also known for their nobility of character.
Kraken Reavers		The Kraken Reavers, known as the 'Víkankrak' in their tongue, are an Ultima Founding Successor Chapter created from the lineage of the savage Space Wolves. This brutal Chapter is comprised entirely of Primaris Space Marines, the next stage of evolution of the Space Marines. Their inception took place in the wake of Abaddon the Despoiler's 13^th Black Crusade in 999.M41. The Kraken Reavers were created as a void shock-assault force, to patrol around the Eye of Terror and the Great Rift to keep in check the Traitor Legions who use it to launch raids across the imperium. As well as any other enemies of mankind who sail within imperial space.
Kraken Scythes		The Kraken Scythes are an eccentric and reserved chapter of the Adeptus Astartes descended from the lineage of Roboute Guilliman's Ultramarines through the 3^rd Founding Scythes of the Emperor. They were created during an unknown founding after the assault on Miral Prime in order to get revenge on the Tyranids in the Eastern Fringe. They are adamant believers in the Imperial Truth and are highly isolated from other chapters. The Kraken Scythes perceive themselves as having the singular purpose of revenge against the Tyranids for the attack on Dantris III and to hunt down and root out Genestealer Cults. The Chapter bears a loose alliance with their presumed parent Chapter, the Scythes of the Emperor.
Kraken Sons		The Kraken Sons are specialised force, much like the Wolfspear, they were created to contain the servants of the Ruinous Powers, in the case of this Ultima Founding Primaris chapter, they were created to try and annihilate the notorious Chaos Lord Huron Blackheart and his marauder empire. Unlike the Wolfspear however, the Kraken Sons were practically gleeful at this posting. Ever since they've made their home on the world of Miðgarðsormr the starlanes about Badab have been alight with the fires of combat; the Kraken Sons and the imperial navy taskforce assigned to aid them have relentlessly chased the Red Corsairs. Though they have not managed to completely obliterate Huron and his empire the Kraken Sons have managed to curb the Tyrant of Badab's raids into their former sector.

The Last Chapter		The Last Chapter, also known as the Capitulum Ultimum, or, colloquially, the Scribes or the Letters, is a Loyalist chapter of the Adeptus Astartes whose founding, lineage and even name remain a subject of controversy. The homeworld of the chapter was destroyed at an unknown point in time, turning the Scribes into a vagrant, fleet-based chapter, lacking a home Sector or even Segmentum, and possessing little to no evidence about their past.
Legion of Solus		The Legion of Solus are a semi-Codex-compliant, relatively unknown Loyalist chapter of the Adeptus Astartes created during the ill-fated 21^st 'Cursed' Founding. Their lineage is unknown, however, it is thought that their gene-stock is chimeric, that is, adultered or somehow mixed, originating from both the noble Blood Angels and the murderous ░░▒▒░░▒. However, rumours of this mixed heritage have yet to be adequately verified, and those detractors who speak of such things do so out of earshot of members of this Chapter. The Legion of Solus is located south of the Segmentum Pacificus, close to planets inhabited within the Veiled Region which are comprised of unmapped vast frontier zones that consist of dense nebulae and newborn stars cloaked in stellar matter and intense radiation emitted by these stars. Their founding reason was to act as a defense force and assist rogue traders in mapping this region beyond the light of the Emperor where Astropaths dare not tread.
Lightkeepers		The Lightkeepers are a loyalist Space Marines Chapter founded in 546.M32, during the 4^th Founding, just after the near disastrous War of the Beast, which nearly brought the Imperium of Man to its knees. Suffering catastrophic losses after making great sacrifices to halt the massive invading Ork WAAAGH!, the Chapters of the Adeptus Astartes began the long, tedious process of rebuilding their ranks. The Lightkeepers were one of several newly created Chapters that came into being during this time. They were created as a Successor Chapter of the heroic Ultramarines. Upon their inception, they were charged to to defend the vitally important Lighthouse System as well as the neighbouring sector.
Lightning		The Lightning are a White Scars Successor Chapter created during an Unknown Founding, although many Imperial savants believe they were possibly created during the 21^st Founding, the so-called 'Cursed' Founding. The Lightning are based upon the planet Saka located in the Thermopylae sub-sector of Sector Occident Prime. They currently serve as one of the Hell Warders - a quintumvirate of five Space Marine Chapters - tasked to defend the Imperium against Chaos incursions from the 'Hellgates', the dual warp storms in the Segmentum Solar which are uncomfortably close to Holy Terra.
Lightning Sons		The Lightning Sons are a Loyalist Space Marine Chapter of unknown Founding and lineage, known to be composed of staunch and aloof Imperial traditionalists. It is widely acknowledged that the Chapter was formed as part of the 23^rd Founding in the late 37^th Millennium, however the lack of any verifiable record makes confirmation next to impossible. Fiercely driven to uphold the ancient edict and dictates passed down by the Emperor of Mankind prior to his internment upon the Golden Throne, the Lightning Sons will go to great lengths to ensure the precepts and ideals of the 'Civitas Imperialis' are upheld throughout the mortal realms of Mankind. Operating from the arid desert world of Navaern, the Lightning Sons have long acted as the stewards of the Pharus Astropathica; a great psychic beacon housing techno-arcana wrought during Mankind's last golden epoch, or so it is said. With a lack of any verifiable history prior to the 38^th Millennium, a lack of verifiable gene-sire and the innate mysteries surrounding their charge, many a dark rumour has circulated Imperial Adepta. Rumours of sedition, of dark pacts and bloody betrayal.
Lightning Wraiths		The Lightning Wraiths are a Loyalist Space Marine Chapter founded in M37 as a Successor Chapter to the White Scars. As such, the Lightning Wraiths retained some of the White Scars' traditions and combat doctrine. They were created in response to an increase in Chaos activity in the Segmentum Obscurus. A chapter born from shame, hate, and vengeance, the Lightning Wraiths are a reclusive chapter with traditions that derive from various death and warrior cults of their home planet. Marines hailing from the chapter are taciturn individuals, speaking only when the situation requires clear and concise communication. Even then, they speak very little to those who are not of the Lightning Wraiths. The only exception to their introverted attitudes are the White Scars, as the Lightning Wraiths are fanatically loyal to their forefathers. However, in the fields of battle, the normally introverted marines turn into savages fuelled by their undying rage.
Lion Blades		Created during the splitting of the original Space Marine Legions, the Lion Blades are a venerable Chapter of the Unforgiven. Dour-faced and grim, the Lion Blades strike rapidly and unrelentingly, piercing into the heart of the enemy. The Lions of Ravenna have a long and storied history, filled with honours and praise. There are however, darker periods, hidden by the fog of memory and concealed by the Lion Blades themselves. Most notable, was the engagement against the Dread Knights that led to the destruction their contemporaries' first homeworld; Cappadocian.
Lions Malevolent		The Lions Malevolent are a Successor Chapter of the line of Primarch Lion El'Jonson, supposedly created sometime during M33, as they were counted amongst the many Adeptus Astartes Chapters deployed during the Lagomort War fought in 238.M33. As descendants of the Lion they are a part of the Dark Angels Successor Chapters collectively known as the Unforgiven. Like the Dark Angels, they too, formed their own Inner Circle to guard the knowledge of their progenitor's secret shame. This Dark Angels Successor Chapter displays a particular zeal in prosecuting their quest against the Fallen Angels. Nothing can dissuade them from this most sacred of quests, to right the ancient wrongs of their progenitors. Even though the Chapter has proven itself in battle, their help is sometimes refused due to their reputation for acting against orders and on occasion withdrawing from a campaign in order to pursue their own, undisclosed ends.
Lions of Babylon		The Lions of Babylon are a ferocious and bellicose Successor Chapter of the unforgiving Sable Lions, who themselves hail from the lineage of the stoic Primarch Rogal Dorn. The Lions of Babylon were created sometime during mid-M35, amid the dark times of the Nova Terra Interregnum, when the Imperium of Man was split into separate interstellar empires. Since their inception, this unforgiving and bellicose Chapter have continued to stand sentinel along the furthest reaches of the Imperium's domain, standing eternal vigil against invading Forces of Chaos and xenos raiders that would dare assail their both their home system and those nearby Imperial worlds loyal to the Imperium of Man. Most unusual, the Lions of Babylon adhere closely to the dictates of the Imperial Creed, sharing many of its teachings and beliefs. The Lions see themselves as superior to the average human, for they believe they are the chosen people of Anu (the God-Emperor), and try to show it at every given opportunity. This attitude often causes friction between the Lions and other Imperial organisations.
Lion's Praetorians		The Lion's Praetorians is an ancient 3^rd Founding Successor Chapter created from the lineage of the venerable and mysterious Dark Angels. Both in doctrine and temperament, the Lion's Praetorians are very similar to their Progenitors, and the two Chapter's teachings are largely consistent. Shunning fame and laurels, the deeds of the Lion's Praetorians are even less well-known than those of the other Unforgiven Chapters, however, they are incredibly zealous and honorable and are devoted members of the Unforgiven (the collective of Dark Angels Successor Chapters), concentrating on their duties to the exclusion of all else.
Lion's Regents		The Lion's Regents, also known as the Kings of the Lion & the Leo Astra or Space Lions, are a fleet-based loyalist Space Marines chapter created during the 3^rd Founding using gene-seed taken from the secretive Dark Angels and are part of the Unforgiven. As their name implies the chapter sees itself as carrying on the will of Lion El'Jonson, sometimes causing friction with other members of the Unforgiven who are seen as acting in their own interests over what the Lion would do. Even their primogenitor chapter is not above being accused of acting out of character for their shared father, currently, Azrael & Colm have an understanding though historically they tend to get at each other's throats easily, as such they are not a very popular member of the Unforgiven.
Lorekeepers		The Lorekeepers are a Loyalist Successor Chapter created from the lineage of the ancient Dark Angels during the 7^th Founding. This specialist Chapter was created for the sole purpose of seeking out and acquiring lost archeotech technology and missing Standard Template Construct (STC) fragments from the Dark Age of Technology. As true warrior-monks of the Emperor, the Lorekeepers are assiduous in the acquisition of ancient lore and missing technology as well as the detailed documentation of their findings for their Chapter's extensive collection of archaic lore.
Lords of Ash		The Lords of Ash are a Loyalist Space Marine Chapter created during the recent Ultima Founding. Hailing from the proud gene-line of Vulkan and the Salamanders, the Lords of Ash embrace many of the same cultural traditions as their progenitors. Through the Indomitus Crusade, the Lords of Ash were used as reinforcements of ongoing battles and crusades. Their battle doctrine favoring rapid assaults, and overwhelming firepower allowed them to turn the tide in the waning wars within the Imperium. The galaxy now split into two, the Lords of Ash have never been more needed.
Lords of Metal		The Lords of Metal are a Loyalist Space Marine Chapter of the Adeptus Astartes created during the ill-fated 21^st 'Cursed' Founding, claiming the bloodline of the indomitable Primarch Rogal Dorn, and specifically, the 2^nd Founding Black Templars Chapter. At first glance, the Lords of Metal seem to make up an exception to the curse of the 21^st Founding; demonstrating no extreme gene-seed mutations, nor curses upon their bloodline, which they attribute to their exceptional faith in the God-Emperor. While this may be the case, they still have not averted the ever-vigilant gaze of the Inquisition, and fellow chapters of the Adeptus Astartes for their unique culture and battle doctrine that call into question both their heritage and their loyalty to the Imperium.
Lost Sons		The Lost Sons are a grouping of Astartes that can scarcely be called an organised Space Marine Chapter, as it is made up of less than two hundred orphaned Space Marines, all of which hail from lost or fallen Chapters. To say that this motley assemblage of Renegades is regarded with suspicion by the Inquisition and the High Twelve would be a massive understatement. The Lost Sons have been on a penitential crusade ever since their First Captain, Andreas Solar, won their lives by successfully passing through the Grey Knights' ordeals. His success earned the band a temporary stay of execution from a reluctant Supreme Grand Master Kaldor Draigo.
Luminant Sons		The Luminant Sons are a loyalist semi-Codex compliant Space Marine Successor Chapter assumed to be created from the White Scars lineage during the 7^th Founding in early M34. Positioned between the Ghoul Stars and Ultima Segmentum, their isolation from the Imperium over time led to deviations from the Codex Astartes, chief among them being their non-adherence to the Imperial Cult. When they were founded, their first Chapter Master received a vision and created five tenets for the Chapter to follow. These were called the Kata of Equanimity, and they believe that only by following these tenets can they reach transcendence and join the Emperor. A direct effect of their belief is their unwillingness to keep relics or dreadnoughts, believing reliance on the material world holds them back from achieving equanimity.
Luna Berserkers		The Luna Berserkers are a Codex-divergent Blood Angels Successor Chapter created during the ill-fated 21^st Founding, to so-called 'Cursed Founding'. Several Chapters created during this particular founding suffered from rampant mutations or aberrant gene-seed. The result of various genetic meddling resulted in the Luna Berserkers possessing an odd quirk in their gene-seed - the twin-flaws of both the Black Rage and Red Thirst possessed by the Blood Angels and those of their bloodline, is near-constant within them, however, it fluxes with the phases of the moon.
Lunar Guard		The Lunar Guard are a Loyalist Space Marine Chapter of unknown lineage created during the 9^th Founding. Once engaged in the tasks of the Ecclesiarchy, to ensure the farthest corners of the Imperium were brought the Emperor's light. after sustaining huge losses they decided to gain a foothold in the Boras Minor sector, which they could then call their home. For their entire existence, the Lunar Guard have been distinguished by their successful notable campaigns and maintaining the Emperor's order within the Boras Minor sector. Under eternal siege by marauding Orks and plundering fleets of Drukhari, the Chapter has gained vast amounts of experience when countering these xenos threats.
Lycaean Liberators		The Lycaean Liberators were originally a Loyalist fleet-based Raven Guard Successor Chapter created during an unknown founding. They were declared heretical for their actions against local governmental assets, but they consider themselves to be still loyal, though they are increasingly distressed by the discrepancy between the state of the Imperium and the ideals of their Primarch Corvus Corax. (Traitoris Perdita)
Lycanthropes		The Lycanthropes are a savage and mysterious Space Marine Chapter created during the 21^st 'Cursed' Founding from unknown lineage. This chapter of Adeptus Astartes teeters on the edge of the Ordo Astartes' tolerance. Brutal and mindlessly violent on the battlefield, they have garnered a grim reputation of carnage and bloody retribution. With no planet to call their own the Lycanthropes are an insular chapter, their offerings of the enemies blood made both to their unknown Primarch (many theorising it to be Leman Russ) and the God-Emperor.
Lyran Guard		The Lyran Guard is a 12^th Founding Loyalist Successor Chapter of the Imperial Fists created in M35 during the time period of the Nova Terra Interregnum. Given the duty by the High Lords of Terra to protect the Gierland Sector from xeno and chaos incursion. In the five millennia since their founding, the Guard have become characterized for their concern of civilian casualties by putting their duty as protectors of the Imperium’s people as their primary objective during their operations.

Name	Image	Notes
Maelstrom Fists		The Maelstrom Fists is a solely Primaris Space Marine Chapter created during the Ultima Founding, formed from the lineage of the Indomitable Imperial Fists. A rather unique chapter, the Maelstrom Fists were formed to specialize in void warfare, to compensate for the losses that the Imperial Navy suffered during the 13^th Black Crusade and the formation of the Great Rift. Thus, the newly formed Chapter chose the ocean world of Pontus as their homeworld.
Mandators		The Mandators are a Loyalist Codex-compliant Space Marine Chapter created during the recent Ultima Founding from the proud and heroic lineage of the Ultramarines. They are comprised entirely of newly revealed Primaris Space Marines, the next stage of evolution of the transhuman warriors of the Adeptus Astartes. This Chapter has close ties to the Inquisition in the Aurum Sector.
Manticores		The Manticores are a Renegade Chapter, originally part of the 'Cursed' 21^st Founding and successors of the Dark Angels, thus making them a part of the Unforgiven. Despite being titled as traitors, that is far from the truth. Near the end of the M40, the Chapter was in pursuit of the infamous Fallen Angel, Cypher, which led to the Manticores coming into conflict with the Inquisition. Rather than revealing the dark secret of the Fallen, the Manticores took the blame and were thus declared traitors. Now they roam the galaxy, chased by their former comrades, with only their fellow Unforgiven knowing the truth. The Manticores continued to protect the Imperium, while at the same time hunting down the Fallen, in hopes of one day redeeming themselves in the eyes of the God-Emperor. Eventually, during the Indomitus Crusade, they were finally pardoned by the resurrected Ultramarines Primarch Roboute Guilliman, who finally granted the loyalist Manticores redemption in the eyes of the Imperium, the Lion and the Emperor.
Marines Baleful		The Marines Baleful are a 15^th Founding Dark Angels Successor Chapter, one with a dark and shrouded history. Originally known as the Angels of Valiance, a proud and arrogant chapter obsessed with their superiority. However, after their arrogance nearly became their downfall, the chapter underwent drastic changes to its structure, livery, and culture, renaming themselves the Marines Baleful. They have since become a mysterious and potent force against the enemies of the Imperium, striking fear into the hearts of their foes.
Maroon Hunters		The Maroon Hunters are a loyalist, 26^th Founding chapter that descends from the gene-seed of the Great Khan, Jaghatai. Founded to patrol the fringes of Segmentum Pacificus and protect it from xenos assaults, the Maroon Hunters have stood compliant to the Codex Astartes and have developed a rather unique culture compared to their primogenitor. A noble and fearsome chapter, they specialize in combating xenos and have adopted expeditionary as well as submissive tactics to quickly pacify or conquer a planet. An aggressive chapter when it comes to pacifying xenos, the Maroon Hunters are notorious warriors, fierce combatants and soldiers unwilling to retreat.
Marauding Eagles		Created around mid-M34, during the 8^th Founding, the sole known successor Chapter of the Destroyers, and through them the White Scars, the Marauding Eagles are the members of an infamous Chapter, whose berserk frenzy has caught the gaze of the Inquisition and the Adeptus Mechanicus. Like their forefather, their bloody conduct in war is marring their otherwise little but effective known records of engagements. However, the many dangers of the Halo Stars against which they stand ever vigilant have always allowed them to evade sanctions.
Martyrs Vindicant		The Martyrs Vindicant were a semi-Codex compliant Blood Angels Successor Chapter established during the 15^th Founding sometime in M35, upon the death world Helis in the Segmentum Ultima. The Chapter would become famed for its fanatical hatred of Orks, often abandoning battlefield objectives and even dooming entire campaigns in an attempt to slaughter any greenskin presence the chapter became aware of. Helis would remain the Chapters' homeworld until the late years of M38, when an apocalyptic Ork WAAAGH! drove the Martyrs from the planet, forcing them to roam the stars as a fleet-based chapter. The Martyrs would roam the stars of the galaxy until 999.M41, when during the fleet's speedy journey to Baal during the Third Tyrannic War, the Cicatrix Maledictim - a massive tear in reality that stretched across the width of the galaxy - flinging the entire Chapter fleet into the depths of Warp space.
Masonic Marines		The Masonic Marines are a semi-loyalist, non-Codex compliant Space Marine Successor Chapter created from the lineage of the stoic and brave Imperial Fists. Some Imperial records state that the Chapter was created during the 3^rd Founding in early M32. In contrast, other records do not mention the Chapter until late M41 during the recent Ultima Founding. There are also different views on the allegiance of the Chapter. Some sources put the Masonic Marines as a true loyalist Chapter, while others describe them as renegades.
Masters of Salt		The Masters of Salt is a loyalist semi Codex-compliant Successor Chapter created from the lineage of the stoic and brutal Iron Hands. The first known record of the Chapter states that it was created sometime during the 11^th Founding in late M35 during the Nova Terra Interregnum. The Chapter was founded as a purely offensive force by order of the High Lords of Terra with the purpose of restoring the order in the Segmentum Pacificus during this dark period in the history of the Imperium.
Mastodons		The Mastodons are a Loyalist Space Marine Chapter created during the most recent Ultima Founding from an unknown lineage. Their Chapter Master, Aldrick Thunderborn, and his council alone know the Chapter's original genetic material, not wanting the gene-seed to direct the Mastodons in how they fight, keeping this knowledge as a tightly held secret. As siege warfare specialists, the Mastodons utilise slow, methodical, precision warfare followed by crushing armoured assaults with overwhelming firepower. Due to their preferred fighting style, the entirety of the Chapter is comprised entirely of Primaris Marines. In battle, the Chapter's planetary assaults are spearheaded by a mobile fortress. This massive city-sized land crawler is transported by an ancient Ark Mechanicus, gifted to the Chapter following a campaign where they helped destroy a series of Dark Mechanicus fortresses.
Maws of Fenris		The Maws of Fenris is a Loyalist Codex Astartes-compliant Space Marine Chapter born of the recent Ultima Founding, and a Successor Chapter of the Space Wolves, composed entirely of Primaris Space Marines. The Maws of Fenris were amongst the first of the Primaris Chapters created in the Ultima Founding. The Maws of Fenris' homeworld is Tûndar, located in the Ultima Segmentum. Though their battle record is still growing, they have already established themselves, having fought against the Orks and the Forces of Chaos.
The Medjay	Pict-File Unavailable	The Medjay is a Successor Chapter of the Salamanders renowned for their fierce loyalty and dedication to protecting the Imperium. They are known for their exceptional skill in combat and their unwavering commitment to justice and honour. Despite the challenges they face, the Medjay remain resolute in their duty to defend the Imperium and uphold the values of the Salamanders. The Medjay was founded as a means of creating and fortifying a defense line from Nocturne to Badab and Chogoris, securing the three sectors from both Chaos and Xenos threats. The Medjay are unique as they practice many of the beliefs and doctrines of the culture of Kemet. They have a close relationship with the civilian population similar to their progenitors and always place civilian lives as top priority during planetary defense as well as missions outside the sector.
Megalodons		The Megalodons are a Loyalist Space Marine Chapter created during an Unknown Founding and from an uncertain lineage. This savage and merciless Chapter was reputedly created in antiquity, but their exact origins are difficult to pinpoint by Imperial scholars, remaining shrouded in the midsts of long-lost antiquity, thousands of years in the past. An isolationist and aloof Chapter, the Megalodons have continuously prosecuted their solitary crusade for millennia, bringing the light of 'Monatoa', 'The Void Shark that Devourers' (God-Emperor), to the darkest corners of the galaxy. Like hungry apex predators, they stalk through the cold, dark depths of the void, striking their foes unexpectedly and tearing them apart, then slip back into the Outer Dark. The Megalodons' ruthless reputation has writ a bloody legacy across the pages of Imperial history, their very name having become synonymous with the merciless butchery of those who would dare assail the realm of Mankind.
Molten Fists		The Molten Fists are a semi-Codex compliant Space Marine chapter founded during the ill-fated 21^st 'Cursed' Founding. They are sons of Primarch Rogal Dorn through the Crimson Fists. Although they have an official homeworld that the chapter returns to at least once every decade, they act mostly in a fleet-based capacity due to their location in the Segmentum Obscurus. Due to their inception during the Cursed Founding, the chapter suffers from a gene-flaw named the 'Internal Flame'. In essence, the marines of the chapter suffer a constant burning pain which they have to manage. However, this does come with the bonus of having a resistance to heat and flame that rivals that of the Salamanders. A marine's worth in the Chapter is frequently based upon his control of this pain. The Chapter's gene-flaw means that they make heavy use of melta weaponry, to the extent of outfitting their new Hellblaster squads with modified melta guns.
Moonlight Stalkers		The Moonlight Stalkers are a Loyalist Successor Chapter whose lineage was derived from the wild and fearless Space Wolves. They were founded pretty early in the Ultima Founding, which means they're comprised entirely of Primaris Space Marines. They strike from the shadows, surprising and overwhelming the enemy forces. The Moonlight Stalkers don't like open battle and they prefer more dense terrain, where the enemy is forced to face them in close combat. They stalk their enemies and are tireless in the pursuit of their prey. As the name suggests they prefer hunting their prey at night, where they can move unseen and surround the enemy without them noticing until the last second.
Mordekaisers		The Mordekaisers (translated to High-Gothic as 'Murder Lords') are a Successor Chapter created as a 24^th Founding of the Imperial Fists. Upon their creation, the Mordekaisers were sent to the far reaches of the Galaxy into the Ghoul Stars. Their destination was the Imperial Starport Düsterlicht, located near Lunaphage before the Malefactus Warp Rift. They specialise in lightning-fast assaults that take out multiple enemy targets in rapid succession as well as void operations. Their tendency to wear battle damage is a symbol of the Chapter's years of enduring hardship that would've wiped out countless other Chapters; a testament to the endurance of the Mordekaisers.
Mortarchs Serpentia		The Mortarchs Serpentia are a Loyalist Space Marine Chapter of Unknown Founding and origin. These frightful and cryptic marines are not the proud, mythic figures that the Imperium idolises as the Adeptus Astartes, but rather a more horrifying, nightmarish force of power armour-clad spectres. Clad in midnight black and polished bone, they stalk from the darkness and the obscure, their death-rattle cries the only warning the enemy will receive before they are cut down by bolt and blade. Wounds that would lay even the mightiest ogryn low are shrugged off and ignored, the only reaction the enemy receives will be the hollow rattle of the wounded marine, as he continues to crunch forward despite grievous injury.
Mortiferous Shades		Created from the genetic heritage of the ominous Death Templars, who themselves were descended from the lineage of the stoic Primarch Rogal Dorn, the 4^th Founding Mortiferous Shades have the same parallel tendencies as their progenitors as they are both fiercely independent and isolationist. This tenebrous reputation with other Imperial authorities as well as their fellow Chapters of the Adeptus Astartes has garnered the Mortiferous Shades an unsavoury reputation, for their cousins view their seemingly unnatural obsession with death and strange mortuary traditions with suspicion. Seen as aloof, they have also been accused of wanting in brotherhood, however, nothing could be further from the truth.
Mourning Cherubim		The Mourning Cherubim were an ancient Loyalist Space Marine Successor Chapter of the heroic Blood Angels. It is not known exactly when this venerable Chapter was created, however, extant records indicate that this Chapter first appeared in Imperial records as far back M32. However, due to the passage of time and human error, there are no definitive records to indicate exactly which Founding this Chapter was created. Due to their supposed creation shortly after the events of the Age of Darkness, these Astartes were perhaps the most emotionally destroyed by the death of their Primarch. These suicidal Space Marines are fearful opponents, utterly unconcerned with their own well-being and driven to join their gene-sire in death, the Mourning Cherubim brought relentless destruction to any they faced. During Hive Fleet Leviathan's invasion of Baal, the Mourning Cherubim finally acquired the release they desired.
Mourning Wardens		The Mourning Wardens were created during the 26^th Founding as a rare Successor Chapter of the Crimson Fists, who themselves herald from the lineage of the stoic and proud Primarch Rogal Dorn. Even amongst the Scions of Dorn, the Wardens are especially stoic and grim. Their pride expresses itself not in the swing of the blade or cold arrogance but in the calm satisfaction of an unbreakable defense being pierced by their efforts or an indefensible outpost holding out thanks to their presence. However, their stubbornness sometimes causes them to endure unnecessary sacrifices in the course of their duties.
Murdering Sons		The 'Homicidialis Filios', more commonly known in the Low-Gothic dialect as the Murdering Sons, are a darkly-famed Space Marine Chapter created with a specific purpose in mind - retribution. This bellicose Chapter was created during the 11^th Founding sometime during the dark times of the Nova Terra Interregnum, a period of extreme unrest and civil strife, when the Imperium of Man was split in half, during the early-to-mid M35. When crimes such as insurrection, rebellion or heresy require not simply crushing the guilty, but exact retribution, the High Lords of Terra deploy the Murdering Sons. These grim warriors are well-suited for the task at hand, displaying a propensity for moral absolution and a drive to enact retribution. The Murdering Sons have utilised the same brutal tactics throughout their millennia of existence, for unexpected violence is their calling card. When they conduct a campaign it is both an unsubtle and bloody affair, but brutally swift.
Myrmidons		The Myrmidons are a Loyalist Successor Chapter created during the 3^rd Founding from the proud lineage of the heroic Ultramarines. However, unlike their fellow Successor Chapters descended from the lineage of Primarch Roboute Guilliman, known for their noble nature and adherence to the Codex Astartes, the Myrmidons were cut from the same cloth as their progenitors, the darkly-famed Imperius Ravagers. Unlike other Scions of Guilliman, this ancient 3^rd Founding Ultramarines Successor Chapter possesses a bellicose nature and brutal mein, and is known for only nominally adhering to the Codex. Inheriting their progenitor's ferocious nature and thirst for war, the Myrmidons have garnered their own brutal reputation for ruthlessly prosecuting the enemies of Mankind, granting them no quarter - only death for their perfidy.

Nameless Stalkers		The Nameless Stalkers are a non-Codex compliant Space Marine Successor Chapter created from an unstated lineage. It is believed that the Chapter was originated from an altered stock ("Chimeric") composed of gene-seed from both the Raven Guard and the Iron Hands, during the 12^th Founding in mid-M35. However, this hasn't been definitively proven, and due to the Chapter's nomadic nature, has been extraordinarily difficult for the Magos Biologis to obtain adequate gene-seed samples for study. Due to a betrayal by a rogue Inquisitor, open conflict ensued between the Inquisition and the Nameless Stalkers, which resulted in the near-destruction of the Chapter and they were declared as a Renegade Chapter. (Traitoris Perdita)
Nemean Brotherhood		Born from the darkness of the 21^st 'Cursed' Founding, the Nemean Brotherhood are a Chapter apart from progenitors. Cast in the fearsome image of the Iron Hands, the Nemean Brotherhood are a force defined more by the actions of their long lost Primarch, than his Legion. Following the example of Ferrus Manus, the Slayers of Typhon are a Chapter of monster killers. Driven to test themselves against the great beasts of their 'world of trials' and the galaxy at large, these sons of the Tenth are as unrelenting and fierce as the Iron Hands who cast them out.
Nemean Lions		The Nemean Lions are a Loyalist Successor Chapter of the stoic Imperial Fists, raised in M38 during the 23^rd 'Sentinel' Founding. Since their inception, the Nemean Lions have steadfastly prosecuted the enemies of Mankind across the width and breadth of the known Galaxy, taking part in many notable conflicts down the millennia. Despite their relative youth, the Nemean Lions have garnered a reputation as highly dedicated and stalwart defenders of the Emperor's domain, and are always eager to answer the call-to-arms should an Imperial world be assailed by heretics, xenos or the malefic. The Nemean Lions always look forward, carving their own legends in the annals of the Imperium's history. Though only a few millennia old, the Chapter has already won many notable victories and earned the approbation of other Adeptus Astartes Chapters and even the High Lords of Terra themselves.
Nergüi Ghosts		The Nergüi Ghosts are an undisclosed Successor Chapter created during the recent Ultima Founding from the lineage of the wild and ferocious White Scars. They were created to answer the growing threat to Chogoris by the Red Corsairs which invaded the system during the events of the 13^th Black Crusade in 999.M41. This Chapter is comprised entirely of Primaris Space Marines that are recruited solely from orphans born on worlds controlled by the White Scars or their Successors. The Nergüi Ghosts are fierce survivalists that excel in unsupported long term missions behind enemy's lines. Their purpose is to sabotage, hinder and slow down traitor invasive forces by constant pinpricks and disruptive attacks. Their unusual non-hierarchical chapter organisation is based on common beliefs and core principles and allows them to operate with great flexibility and autonomy.
New Dawn		The New Dawn are a Loyalist Successor Chapter created during an Unknown Founding, sometime in late M37, from the proud lineage of the heroic and venerable Blood Angels. Like many of their fellow Chapters of the Blood, the New Dawn has a predilection for close-combat and shock assault tactics. The blood of Sanguinius burns like fire in their veins, and the New Dawn has garnered a reputation as being savage and bloodthirsty in nature. As they are greatly affected by the twin genetic-flaws inherent in their gene-seed, instead of fearing it, the New Dawn embraces these 'flaws' as blessings from the Red Angel.
Night Furies		The Night Furies are a Ultima Founding semi-Codex compliant Chapter formed from the long lost Blood Wyverns 5^th Company at the dawn of M42 during the Indomitus Crusade. Currently based in the Highlands Sector on the border of Segmentums Pacificus and Obscurus, the Night Furies have taken up residence on a rogue planet in open space, referred to as Redemption by the Chapter. Currently operating in relative seclusion from the rest of the Imperium, the Night Furies have been tasked by the Primarch with patrolling the border of the Cicatrix Maledictum closest to their territory for Chaos incursions and defending nearby Imperial worlds from invasion. In addition to this tasking, the Chapter also maintains a secondary objective in this region known only to them: to hunt down their former brethren in the Blood Wyverns, who have since turned to the service of the Ruinous Powers in the 5^th Company's millennia of absence, and to destroy them in order to remove the black stain upon their honour.
Night Guard		The Night Guard is a Loyalist Chapter, that is shrouded in mystery. Created during the mysterious 13^th Founding, the mysterious 'Dark Founding'. Little is known about this obscure Chapter, only when they were created and that they are formidable void warfare specialists and are almost unbeaten in this realm of conflict. They tend to go out in the void in special hardened armour and drift towards an unsuspecting enemy vessel. In this was they can infiltrate the enemy vessel undetected. Other Chapters might find this suicidal, but the Night Guard are masters at doing so. Going out in space without a vessel is their way of war.
Night Ghosts		The Night Ghosts are a Loyalist Space Marine Chapter of the ill-fated 21^st 'Cursed' Founding. They are one of the most feared chapters of the noble warriors of the Adeptus Astartes. But what most people do not know if they read the many reports of the satanic tortures of the Night Ghosts are that the Chapter follows the honourable regulations of the Cult Prometheus from the noble Salamanders with the same fanaticism. And even less know the second face of the Night Ghosts - a friendly albeit very reserved mind. Whatever imperial organisations think about the Night Ghosts, one thing no one can deny - wherever the Night Ghosts fight in a war the losses to civilians number close to zero. If a tyrant enslaves innocents or criminals who rob the population, no wrong can survive against the Night Ghosts.
Night Ravens		The Night Ravens are a mysterious, if not oft-maligned, Chapter of the Adeptus Astartes, who, despite being labelled as one of the 'sullied' Chapters of the 21^st 'Cursed' Founding, has managed to forge a reputation for melding stealth and guile with vigilance, swiftness and perseverance. Like their progenitors, the Raven Guard, these Scions of Corax have become worthy successors as masters in the arts of stealth and speed, raising these skills to near preternatural levels. Developing their expertise over several millennia, the Night Ravens have carved a swathe of blood and ash across the void against the multitude of enemies that have assailed Mankind.
Night Sentinels		The Night Sentinels is a Loyalist Space Marine Chapter of the Adeptus Astartes and a suspected Successor Chapter of the Salamanders, formed during the Ultima Founding. The chapter is composed of a mix of Primaris (Greyshields and newer recruits) and Firstborn (just under a hundred from different companies of the Salamanders) Space Marines. Their tasking is to protect Imperial interests and, more importantly, Imperial citizens in the Imperium Nihilus, the area of space opposite of Terra of the Great Rift.
Night Terrors		The Night Terrors are a mysterious and aloof Loyalist Space Marine Chapter created from uncertain lineage and founded during the turmoil of mid-M35. During these times, such as the events of the Nova Terra Interregnum, the Imperium was in a time of disorder and chaos. The Night Terrors were born of such chaos, moulded from the very fabric of disorder and hatred that had torn the Imperium in two. The Astartes of the Night Terrors are more vengeful murderers then soldiers, walking the line between necessary evil and unchained horror. The Chapter quickly gained a reputation as bringers of terror and death, not from every dark corner, but any dark corner.
Night Walkers		The Night Walkers are a Codex-compliant Space Marine Chapter of Unknown Founding and uncertain lineage. They are based on Morrowdim, a world of the Hadronian Wall in the Aliris Sector. This Chapter has garnered a fearful reputation for their use of terror tactics and psychological warfare against their enemies and have often been the subject of numerous Inquisitorial investigations for committing several massacres.
Night Wendigo		The Night Wendigo is a Loyalist Space Marine Chapter, of a unknown origin that was raised during the 13^th Founding, the so-called 'Dark' Founding in M35. Though some imperial scholars have reported sightings of this Chapter dating back to the 2^nd Founding, yet this still remains unconfirmed. The Night Wendigos are a vicious, bellicose and violent chapter, even to Astartes standards. They have been seen wearing flayed skin and collecting skulls as if they were some kind of macabre trophies. Because of this they have been compared to the traitorous Night Lords legion. Unlike other chapters that uplift worlds, the Night Wendigos bring nothing but terror and dread. When the Night Wendigo arrive to a planet, they do not come to liberate, they do not come to save, they come to bring judgement on the Emperor's foes. They care little for the citizens of the Imperium. Instead, they desire nothing less than the total extermination of the Emperor's foes, believing that he will save the souls of the innocent and destroy those of the guilty.
Night Wolves		The Night Wolves, more accurately the Vilka Natt, are a Primaris Space Marine chapter of the Ultima Founding and successors of the venerable Space Wolves. Renowned for both their brutality and boastful nature, the Night Wolves are perhaps the most amiable to outsiders of any of Russ' sons.
Nightscream		The Nightscream are a mysterious Successor Chapter created from the lineage of the Raven Guard during the ill-fated and oft-maligned 21^st Founding, the so-called 'Cursed Founding', sometime during M36. Like many Chapters created during this Founding, the Nightscream were one of these Chapters affected by the Adeptus Mechanicus' failed attempts at genetic manipulation, which resulted in the Chapter suffering from a debilitating flaw that affects their vision, which rapidly worsens until the affected battle-brother is rent completely blind. However, this unnatural blindness has resulted in them developing far superior senses than even a standard Astartes - superior hearing, an enhanced sense of smell, tastes and acute sensitive touch. Utilising these innate abilities, down the millennia the Nightscream have developed superb expertise in stealth, infiltration and deep strike tactics deep behind enemy lines, committing acts of sabotage, assassination of enemy commanders, and the sowing of destruction and chaos behind the lines mid-battle.
Noble Angels	Pict-File Unavailable	The Noble Angels is a Loyalist Space Marine Chapter created during the mysterious 13^th 'Dark' Founding. They are notable for not only being one of the few Space Marine Chapters that possess chimeric gene-seed, but also one of the very rare ones which possess gene-seed of three different Space Marine Legions. Members of this Chapter are recruited from different noble families from around the galaxy, prefferently from warrior castes. Noble Angels see themselves as Scholar-Knights and Shepard-Marshals with the aura of Warrior Angels. They protect the common people and serve as inspiring beacons on the battlefield and as beacons of the faith in non-combat, seeking always new cultural accomplishments.
Nova Knights		The Nova Knights is a Loyalist Space Marine Chapter and 10^th Founding Successor of the Ultramarines Legion. It was created as a replacement Chapter on the Mundano Sub-Sector, taking both the name and colors of the previous chapter known as Nova Knights, lost in a forgotten conflict. The Nova Knights are adherents of the Codex Astartes, penned by their blessed Primarch Roboute Guilliman.
Nova Wolves		The Nova Wolves Chapter was formed in the 26^th Founding from an unknown genetic lineage in 739.M41, with the purpose of defending the Imperium from the threats of both xenos and heretics alike. They specialize in void warfare and ship-to-ship boarding actions, but are no slouches on the ground, as they are masters of ranged assaults against the enemies of Mankind.
Nova Scions		The Nova Scions are an Ultima Founding chapter made entirely of Primaris Space Marines specializing in urban warfare as well as daring Overlord dropship assaults. Although they have often been deployed against traitor Imperial elements and have acquitted themselves loyally and honorably, some of their actions have led the more religious, callous, and fanatical elements of the Imperium, especially the Ecclesiarchy and the Inquisition, to raise questions about the chapter's loyalty, particularly as their background is unclear at best.
Novadracones		The Novadracones is a Loyalist Space Marine Chapter and 26^th Founding, created as a Successor Chapter of the Novamarines, whom themselves are descended from the lineage of the Ultramarines Legion. The chapter's homeworld is Gamatorius, the capital of the Gamator System.

Obsidian Blades		The Obsidian Blades are a Codex-deviant Space Marine Chapter created during the 21^st 'Cursed' Founding from Raven Guard gene-stock. Their heritage and gene-seed lineage already leaned them towards a more reserved, practical and cunning approach to war, which has only been exacerbated in recent centuries as the Chapter has faced many hardships and near extinctions. The Obsidian Blades believe in ensuring the battle is won before a single shot is fired, sabotaging key structures and poisoning enemy supplies so that when the Obsidian Blades do emerge from the shadows like ghosts, the enemy is already weakened and debilitated. They creep forward under the cover of darkness and stealth, eviscerating lookouts and watchmen silently, utilising combat knives the use of which the Obsidian Blades have perfected.
Obsidian Champions		The Obsidian Champions, often referred to as "Sanguinius' Marauders" and known as "𐌶𐌴𐌰𐌻𐍉𐌿𐍃 𐌺𐌽𐌹𐌲𐌷𐍄𐍃 𐍉𐍆 s𐌰𐌽𐌲𐌿𐌹𐌽𐌹𐌿𐍃" are an Ultima Founding Successor Chapter whose origin and history traces back from the tragic chapter of the Blood Angels, primarily consisting of all of Primaris Space Marines. Despite being the sons of Sanguinius, their entire philosophy comes from the zealous Black Templars whose devotion to the Emperor Of Mankind is extraordinary among other chapters of the Adeptus Astartes. Moreover, their hatred towards other vile xenos races is nothing but a short rage of madness as these religious marines will go to great lengths to ensure each race tastes the wrath of Master of Mankind.
Obsidian Fists		The Obsidian Fists are a mysterious Codex-compliant Successor Chapter of the staunch and heroic Imperial Fists. For a time they were treated with a certain level of mistrust by other descendants of the VII^th Legion as some questioned the Obsidian Fists' right to call themselves Sons of Dorn. Like their fellows, they are renowned for their stubbornness and tenacity in their prosecution of the Emperor's foes. They use their mastery of siege warfare and area denial to protect Imperial worlds primarily in the Hallstat Sector.
Obsidian Griffons		The Obsidian Griffins are a mysterious Chapter created during an unknown Founding, supposedly from the lineage of the ancient Raven Guard. They are currently located far away in the heart of the Imperium Nihilus. Their history and existence are almost unknown to the Imperium itself, except for a few institutions such as the Inquisition. They call themselves the Medren Arogard, a name that instils terror into the hearts of their enemies. This loyalist chapter is currently waging a defensive war on the small portion of the territory it occupies against the forces of chaos and Tyranid invasions.
Obsidian Shadows		The Obsidian Shadows is an all-Primaris Raven Guard Successor Chapter that was created in the Ultima Founding for the sole purpose of ruthlessly destroying Chaos Cults that are hidden within Imperial planets. Due to their skills and expertise in dismantling these cults when they arise, this chapter created an alliance with the Ordo Hereticus as this Inquisitorial Faction is dedicated to the same goals as this chapter.
Obsidian Spears		The Obsidian Spears is a 12^th Founding Successor Chapter of the Angels of Vengeance, grim hunters in the mould of the old First Legion in the glory days of the Great Crusade. For 5,000 years and more, they have patrolled the length and breadth of the Imperium's troubled frontiers and stood sentinel over its darkest places, uncaring of glory and believing that to excel at destroying the Emperor's foes is the highest honour. Observers note this chapter to be a wrathful, isolationist and extremely technologically capable force willing to go to extremes of pragmatism in the name of victory.
Obsidian Talons		The Obsidian Talons are a Loyalist Chapter who - unknown to the vast majority of the Imperium for millennia - was Founded during the 21^st (the so-called 'Cursed') Founding. They are often characterised by their aggressiveness, secretiveness, mistrustful nature and their employment bionics on a massive scale. Known for their abilities to exterminate xenos breeds, they predominantly operate on the Eastern Fringe in the untamed areas of space where xenos still run rampant. They are also known to successfully campaign against Tyranid Hive Fleets and splinter fleets thereof.
Omega Knights		The Omega Knights Chapter are a Loyalist, Codex-compliant Space Marine Chapter that deviates little from it's tenants with the exception to markings on their battle-plate. This Chapter was formed during the 26^th Founding in 738.M41, with the purpose of defending the Imperium from the threats of both xenos and heretics alike. It is unknown from whom they first drew gene-seed from.
Omni-Legion		The Omni-Legion is a Loyalist Space Marine Chapter of the Adeptus Astartes whose origins and exact lineage are unknown. It is unknown when exactly they were created, however, extant records indicate that they were more than likely created in the wake of the so-called Moirae Schism which occurred sometime in late M35. The Omni-Legion would fight in the Gulf of Black Shadows fleet war for centuries, continuing to exterminate Moiraean Hereteks. The number of vessels captured by the Omni-Legion at this time gained them the reputation of boarding specialists.
Omniscions		The Omniscions are a Loyalist Codex-compliant Successor Chapter created sometime during M36, during an Unknown Founding, from the lineage of the stoic and unforgiving Iron Hands. Like their genetic forebears, the Omniscions are well known for their fanaticism of the Cult Mechanicus.
Onyx Blades		The Onyx Blades are a Loyalist Space Marine Successor Chapter created from the lineage of the ancient and aloof Fist Founding Dark Angels. However, despite their claim as being created during the mysterious 13^th Founding, the so-called 'Dark Founding', official records are incomplete and fragmentary. Debate still rages into the modern era, whether or not the Onyx Blades were created during this mysterious Founding.
Onyx Executioners		The Onyx Executioners are a foreboding and mysterious fleet-based Chapter, supposedly created during the 23^rd Founding, the so-called 'Sentinel Founding', from unknown genetic lineage. Originally known as the Crusaders of Glory, this Chapter garnered a reputation as being a humane and pacivistic Chapter that had a reputation for sparing their enemies instead of outright destroying them, often turning them over for interrogation to agents of the Inquisition. However, their merciful nature would prove to be their undoing. In the early decades of M41, a good portion of the Chapter become wholly corrupted by the malefic powers of the Dark Gods, following the capture of a powerful daemonhost. This caused an internecine conflict between the remaining loyalists and Chaos-corrupted brethren, resulting in a full-blown Chapter civil war. After defeating their traitorous brethren, those few loyalist that survived were eventually pardoned and granted the Emperor's forgiveness. To further distance themselves from their treacherous former kin, they changed their heraldry, iconography and Chapter name to the Onyx Executioners.
Onyx Phoenixes		The Onyx Phoenixes are a hard-pressed Chapter of Space Marines located deep in the Ghoul Stars, fighting against the nightmarish threats that overwhelm what little bastions of resistance remaining in that tormented region of space. An unusual Chapter borne of unusual events, they have adapted to survive their environment and made a tightly wrought pact with the secretive Blades of Onyx, a renegade Astartes force with which they share a hidden ancestry. The Onyx Phoenixes focus on large-scale warfare, presenting an impenetrable shield to their enemy, and cutting the enemy apart around it.
Onyx Stars		The Onyx Stars are a Loyalist Space Marine Successor Chapter descended from the lineage of the heroic and compassionate Salamanders. They are a newer Chapter comprised entirely of newly-revealed Primaris Space Marines. They were created as a part of the recent Ultima Founding to take part in the Indomitus Crusade and to stand as a bulwark against the enemies of Mankind.
Optimus Legion		The Optimus Legion is a 3^rd Founding Space Marine Chapter drawn from Ultramarines stock, founded for the defense of the fortress-sector of Alsatia. Bearing an unwarranted reputation for cowardice and a well-earned reputation for cunning. These imaginative marines have held the line for ten thousand years, out-smarting and out-fighting all manner of foes beyond the borders of the Imperium. Specialists in air assault and rapid, highly mobile warfare, the Optimus Legion makes liberal use of aerial transports to quickly reposition and maneuver to counter threats. The Optimus Legion, as a chapter, place a high value on cleverness and quick thinking as virtues of a warrior, even with the consequence of a loss of viciousness and fury. This has garnered them a reputation for being less fierce, less committed, and less zealous than other chapters, for which they aim to compensate with the skill and creativity of their execution of war.
Orcinus Astra		The Orcinus Astra (better known as the Blackfish) are a semi-Codex compliant loyalist chapter of unconfirmed descent from the 25^th Founding. They operate off of their home world of Oceanus. They work intimately close with the Adepta Sororitas Order Dolphinus in their mission to "defend mankind by preserving humanity". Their Xung (Chapter Master) has declared his own personal Crusade against the Caracharadons Astra for, "the Red Tithe's assault upon human virtue".
Ordinators		The Ordinators are a 23^rd Founding, semi-Codex compliant Space Marine Chapter thought to have been founded by order of the Ordo Malleus to build on the successful practice of Daemonic Possession Therapy to create a specialized anti-Chaos Astartes chapter in a besieged corner of the Imperium. The Ordinators were first mentioned in Administratum records as one of very few Space Marine Chapters with a permanent homeworld within the Segmentum Pacificus in late M38, and are considered by those who know of their presence to have been one of the "Sentinel Chapters" formed to protect the frayed borders of the Imperium In a region which is subject to frequent infiltration by the forces of Chaos.
Owls of Judgement		The Owls of Judgement are a loyalist, semi-Codex compliant Space Marine Chapter, comprised entirely of Primaris Space Marines. They were created to fight the myriad of Chaos uprisings springing up throughout Imperium Nihilus the in the wake of the formation of the Cicatrix Maledictum. Unlike most sons of Corax, the Owls are myopic, bellicose, paranoid, and obsessed with enacting their own sense of justice on each planet they pacify. These trials can last months, or even years, as the Astartes attempt to narrow down who is responsible for the uprising, and punish them accordingly. Since the beginning of the Fourth Tyrannic War, they have also begun to persecute Genestealer Cults.

Paladins of Caliban		The Paladins of Caliban are a Successor Chapter created from the lineage of the ancient and mysterious Dark Angels. As they're an Ultima Founding Chapter, they're composed entirely of Primaris Space Marines. As a member of the Unforgiven, they've learned their progenitor chapter's secrecy and, as such, have been known for being extremely secretive towards their allies during battles or campaigns.
Paladins of Thunder		The Paladins of Thunder are a semi-Codex compliant chapter created during the Ultima Founding born from the gene-seed of the loyalist Primarch Rogal Dorn of the Imperial Fists. This chapter gained some notoriety during the Indomitus Crusade helping their brothers, the Crimson Fists in their darkest hour alongside them against the daemon incursion of the Daemon Prince Rhaxor and, later, helped a Salamanders Successor Chapter; the Drake Bloods in the desert world of Nimrod. One of the peculiarities of the chapter is that most of their high-ranking officials are members of the Apothecarion of the chapter. This is particularly notable with the title that the leader of the chapter bears: Magister Medicae.
Palatine Scimitars		The Palatine Scimitars are a loyalist, Codex-compliant chapter famed for their peace-bringing campaigns and high faith in the Emperor. Their gene-seed is unrecognised by the Imperium but it is suspected they are successors of the Archangels of Manasseh, a chapter descended from the Ultramarines. Despite their dark past and the rise of [REDACTED], the Palatine Scimitars still fight hard to deliver light to the fallen worlds of the Imperium.
Palatine Sons		The Palatine Sons is a little-known Loyalist Successor Chapter created under mysterious circumstances during the ill-fated 21^st Founding, the so-called 'Cursed Founding'. Officially, this Chapter's genetic lineage was derived from one of the ancient First Founding Chapters - the stoic and unforgiving Iron Hands. Though outwardly, they appeared physically perfect and possessed an aura of aesthetic refinement, secretly, they harboured an unnatural drive towards perfection and a haughty attitude towards baseline humans whom they deemed inferior and beneath them. Despite acquiring a long and enviable record of battlefield glories during their long service to the Imperium, as a 'Cursed' Founding Chapter, they are often looked down upon by more venerable Chapters of the Adeptus Astartes, who believe the Palatine Sons are somehow tainted or sullied due to their questionable origins. However, if their true genetic heritage was revealed they would be deemed as 'traitors' and hunted to the ends of the galaxy.
Palatine Vindicators		The Palatine Vindicators are an aristocratic loyalist Space Marine Chapter created during the 4^th Founding in 546.M32 as part of the alliance of newly founded chapters that were mentored by the Hussars Sanguine. Though their genetic lineage is unknown, this Chapter has garnered a reputation as stalwart defenders of the Imperium of Man.
Panthers of Kiavahr		The Panthers of Kiavahr are a Successor Chapter of the Raven Guard, sons of the great Primarch Corvus Corax. They have been created during the Ultima Founding, composed entirely of the newly unveiled Primaris Marines. The Panthers of Kiavahr are a fleet-based Chapter and their flagship is called the Shadow Claw. Like Raven Guard they are masters of stealth and hit-and-run attack, however, they are considerably more aggressive and brutal than their progenitors.
Patriarchs of Iron		The Patriarchs of Iron are a Loyalist Space Marine Successor Chapter descended from the lineage of the stoic and unforgiving Iron Hands. They are a newer Chapter comprised entirely of newly-revealed Primaris Space Marines. They were created as a part of the recent Ultima Founding to take part in the Indomitus Crusade and to stand as a bulwark against the enemies of Mankind.
Penitent Gates		The Penitent Gates are a loyalist non-Codex-compliant chapter founded during the 21^st 'Cursed' Founding from the gene-seed of the Dark Angels at the end of M35. The Gates are part of the Unforgiven, the collection of Dark Angels successors dedicated to hiding the heretical past of the I^st Legion. The Penitent Gates consider themselves cursed from the fall of Caliban, and as such take a vow of anonymity and silence upon progression to the ranks of their chapter. A Penitent Gates battle-brother (Knight) will never show their face or speak out loud even to another brother of the Unforgiven, until the fateful day they see their penance complete.
Penitent Knights		The Penitent Knights Chapter is an ancient and fabled Codex-Divergent Chapter with an unknown origination from the 3^rd Founding during the early years of M32 bearing an extremely chivalric culture and attitude. The most obvious difference from most other Astartes Chapters is that the Penitent Knights fiercely and zealously believe in defending the citizens of the Imperium, which is backed with learned ferocity and determination. Often the honorable Penitent Knights contested with other Imperial forces that civilian life is indeed worthy of protecting, as they point out, was their purpose: to safeguard humanity. To die fighting the abhorrent enemies of Mankind so that defenseless humans may escape death is held in the highest respect among the Knights, second only to do the same and live. Standing defiantly against the forces of Chaos in Segmentum Obscurus for many long millennia has provided them with many opportunities to earn these respects. In possession of the Aegimius System, of the Asteria Sub-sector, very close to the Great Rift created early in M42, the Knights defended their home from frequent Chaos threats, as well as the revelation of their homeworld being a Necron Tomb World. With all of the adversity thrown at them, the Penitent Knights have become nearly depleted, spared destruction thus far by alliances with other Astartes Chapters, and by their own renowned fury.
Phantom Knights		The Phantom Knights are a now-extinct loyalist Codex-compliant Space Marine Successor Chapter created from the lineage of the legendary and feared Dark Angels during an unstated founding in 831.M33. They were founded as a fleet-based Chapter with the task of patrolling and securing the utmost border areas of Segmentum Obscurus, the region of Imperial space to the galactic north of Terra.
Phoenix Brethren		The Phoenix Brethren are a mysterious Loyalist Space Marine Chapter of unknown origin and uncertain lineage, though rumours abound that they are the remnants of the mysterious Flame Falcons, one of the many Chapters created during the 21^st 'Cursed' Founding that was afflicted with rampant mutations. After they began showing signs of a disturbing mutation that caused their bodies to spontaneously burst into flames that did not burn their own flesh, their Chapter homeworld of Lethe was assaulted by the Grey Knights. A small number of Flame Falcons miraculously escaped this dire fate and fled for parts unknown. These surviving Astartes now operate secretly in the thinly settled Podomos Reach with the tactic support of a few merchant chartists, frontier governors and an equally secretive Adeptus Mechanicus sect.
Phrygian Knights		The Phrygian Knights are an Imperial Fists Successor Chapter, founded by Antigonos Kertes, who was formerly a captain of the 547^th Phalanx Warder Company. Their Primarch, Rogal Dorn, ordered the formation of the Phrygian Knights during the Third Founding in order to establish a firm and permanent presence of his sons in the galactic far East, between Hexos, Formund and Asylus. And so the warriors of Antigonos Kertes made their home the world of Korengal, in the Phrygian Sub-sector, during the dawn of the 32^nd Millennium. Since then the Chapter has battled against the enemies of Mankind, using the Phrygian Sub-Sector as a lynchpin for their expeditions. Their notable campaigns are many, such as the Three Battles for Alamain in M38, the Retreat from Qart-Hadast in M40, the Anabasis of Stratonike and the Battle for Korengal in M42, to name a few.
Pilgrims of Sanctus Penitents		The Pilgrims of Sanctus Penitents is a very small and unique non-Codex compliant Chapter composed of Space Marines from several different Chapters. The Chapter is on an eternal crusade, following the rare Pilgrim-Pattern, travelling to all known Shrine Worlds in the galaxy. Spreading the Imperial Cult throughout the territory of the Imperium. And smite all heretics and traitors along the routs, in the name and with the fury of the Emperor. Thousands of sinners and heretics together with hundreds of fanatic preachers, devoted missionaries and redemptionists follow the Chapter on its crusade through the void.
Platinum Souls		The Platinum Souls are a Successor Chapter of the stoic and much-vaunted Imperial Fists, created during the notable 23^rd 'Sentinel' Founding during the latter part of M37. This Founding was one of a series of linked Foundings that took place during this tumultuous period in Imperial history. They were intended to repair the power and reach of the Adeptus Astartes that had suffered considerable losses in the preceding millennia. Like their forebears, the Imperial Fists, the Souls are masters of offensive and defensive siegecraft. Unlike the Fists, however, they choose to actively seek out siege opportunities and prefer the wars of attrition that come with dense urban fighting.
Polar Flares		The Polar Flares are a 4^th Founding and rare Successor Chapter created from the lineage of the shadowy Raven Guard. This Chapter was formerly located in the Polaris Sector, but has turned renegade and accompanied the 'Crusade of Renegades' trek to the Solarain Sector, where they meet with the abhumans known as the Elementi. (Excommunicate Traitoris)
Praetorian Guard		Founded at the onset of the Indomitus Crusade, the Praetorian Guard is a Successor Chapter of the venerable Ultramarines. The Intrepidus, their fortress-monastery, stands as a mighty Ramilies-class Starfort. Little do the Praetorian Guard know that this grand structure, shrouded in the mists of history, once belonged to a loyalist splinter faction of the hated Emperor's Children. It was during the tumultuous era of M32 that this enigmatic faction vanished, leaving behind a legacy of mystery and unanswered questions. Unbeknownst to the present-day Praetorian Guard, the Intrepidus carries the hidden remnants of its loyalist Emperor's Children origins, serving as a silent testament to the obscured history of their chapter.
Praetorians of Blood		The Praetorians of Blood are a loyalist Space Marines Chapter initially created during the 4^th Founding, using gene-seed taken from the angelic Primarch Sanguinius via the Hussars Sanguine. Following the Devastation of Baal the Firstborn members of the chapter were killed upon returning to their homeworld of Katon, ambushed by the Carmine Reavers renegade Chapter, who had occupied the entire system. The chapter was quickly reformed with Primaris marines during the Ultima Founding.
Prædicators		The Prædicators Chapter was created around the time of the mysterious event known as the Year of Ghosts from their genetic forebears – the Silver Skulls – whom themselves were descended from the proud and heroic lineage of the ancient Ultramarines Legion. The Prædicators Chapter is dogmatically loyal to the Imperium of Man and the memory of their Primarch Roboute Guilliman and can be counted upon to fight against any foe that dares encroach upon the Emperor's realm. Sharing as they do the genetic inheritance and many of the traditions of the Ultramarines, the Prædicators are above reproach. In many ways, however, the Prædicators are very different to the other inheritors of Guilliman's legacy. The Astartes of the Prædicators are overtly maudlin in demeanour, with many brethren appearing to be consumed by morose thoughts of nihilistic tendencies. However, they have learned to channel this darkness via their rites and traditions into a formidable weapon with which to engage the enemies of Mankind.
Primal Hunters		The Primal Hunters are a venerable 3^rd Founding Successor Chapter of the ancient Dark Angels. First appearing in Imperial records as the Angels of Judgement, they later became savage, yet noble warriors following their two-hundred-year isolation upon the death world of Solutrea. While generally disregarded as primitive brutes by the rest of their Unforgiven Brethren, they have proven no less effective in their pursuit of the Fallen, persecuting these infamous traitors with a level of subtlety otherwise uncharacteristic of them.
Protean Vipers		The Protean Vipers are a Loyalist fleet-based Space Marine Chapter of uncertain founding and origin. It has been involved in numerous campaigns across the Imperium with notable, heavy involvement in the Indomitus Crusade. The culture of the Protean Vipers is one of self-reliance and independent thought to the point that commanders will often consider the opinions and carry out strategies devised by their subordinates. However, this is only possible due to the strict, efficient command structure that is then used to carry out the battle plan once decided on. The Vipers are well known for maintaining good relations between many chapters and have been documented to help ease relations between rival chapters.
Prowlers		The Prowlers are a Loyalist Space Marine Chapter created during an unknown Founding sometime in the 36^th Millennium from the proud lineage of the stoic Imperial Fists. At first, it was not known who this Chapter's genetic lineage was, however, they were later confirmed to be Scions of Dorn by their first Chapter Master, Typhus, during a crusade to find out their origins.
Purgatorians		The Purgatorians are a Loyalist Space Marine Chapter created during the recent Ultima Founding that is comprised entirely of Primaris Space Marines, the next generation of transhuman warriors and far superior to their Firstborn cousins. Not much is known about this Chapter's origins or from which genetic lineage they are descended, and the few extant records that exist are contradictory or have been redacted by order of the High Lords of Terra.
Purifiers		Of all the horrific enigmas spawned by the 21^st 'Cursed' Founding, the Purifiers are perhaps the most terrifying. Like most born during that dark time, these Astartes did not last long. Though others such as the Blood Gorgons succumbed to either corruption in their minds, bodies or both, the madness of the Purifiers was something deeper, something the Imperium at large could little understand. Exemplary even by the nightmarishly high standards of the Adeptus Astartes, the mystery of the Purifiers' extermination will eternally puzzle those few who know of them. (Excommunicate Traitoris)
Purge Marines		The Purge Marines are an elusive and paranoid Chapter of (seemingly loyal) Space Marines created during an Unknown Founding and from uncertain lineage. They are noted for the fact that the Imperium has an astounding lack of information on the Chapter. It is for this reason the wider Imperium remains suspicious of this Chapter. This feeling of suspicion appears to be mutual as the Purge Marines seem to see everyone as a potential Heretic waiting to reveal their treasonous nature. This mutual suspicion has lead to numerous inter-Imperial conflicts. It is suspected that the Chapter's battle doctrine is incredibly violent, viewing the butchering of their enemies as the highest form of religious worship. The Purge Marines display an odd fixation with death and appear to be obsessed with memento mori - artistic or symbolic reminders of the inevitability of death.
The Pure		The Pure are a semi-Codex compliant loyalist Space Marine Chapter of ancient provenance, created during the 3^rd Founding in 001.M32. They are rumored to be a Successor Chapter created from the lineage of the heroic Salamanders. They are known for their selfless attitude on the battlefield, always aiming to save as many civilian lives as possible and to ensure there is no unnecessary collateral damage to a planet's infrastructure, if at all possible.

Quartermasters		The Quartermasters Space Marine Chapter are a loyalist non-Codex compliant Successor Chapter that was created from the lineage of the efficient but ruthless Iron Hands. It is uncertain when the Chapter was created, but some archives indicate that it was probably sometime between the M35 and M36. The Chapter is known throughout the galaxy for its skills and tactics in armoured warfare. Just like most Chapters descended from the lineage of Ferrus Manus, the Battle-Brothers of the Quartermasters have extensive cybernetic augmentations and they constantly replace the weak biological matter to increase their effectiveness on the battlefield. Their quest for self-improvement leads them to see empathy and compassion as major weaknesses that diminish their resolve and strength in battle.

Radiant Scars		The Radiant Scars are an Ultima Founding chapter of the Adeptus Astartes, formed by the command of the Blood Angels' Chapter Master, Lord Commander Dante, following the Devastation of Baal and the arrival of Rouboute Guilliman and the newly unveiled Primaris Space Marines. As a fleet-based chapter, they patrol the area of the Red Scar, a sub-sector of the Ultima Segmentum, which is home to the Baal System.
Rampant Lions		The Rampant Lions are a Loyalist Successor Chapter created during an unknown founding sometime in the latter years of M41 from the proud lineage of the stoic Imperial Fists. As inheritors of Dorn, this proud Chapter stands as a bulwark against the encroachment of Imperial space by the upstart xenos race known as the T'au in an effort to halt their expansionist efforts into the Emperor's realm. The Rampant Lions stand as stalwart sentinels upon the fringes of the known galaxy, immoveable and stubborn, refusing to acknowledge defeat in the face of overwhelming odds.
Rampart Boars		The Rampart Boars, known as the 'Xargha'Khai-ne' in their own language, is a Loyalist Chapter of the Adeptus Astartes created during the 3^rd Founding in the year 003.M32, a few short years after the start of the noted founding of the early 32^nd Millenium from the lineage of Jaghatai Khan.The Rampart Boars are considered by the Ordo Astartes to be a valuable asset in the destruction of xenos threats, particularly the prevention of and even removal of Orks from planets and the destruction of Genestealer Cult threats from Hive Fleet Orthrus. The initiates of the chapter are known for being tall, with abnormally thick bones and a large oddly proportioned musculature from genetic inclusions they refer to inaccurately as "atavisms". Their physical strength is covered with only a thin veneer of nobility over their savage, and often unstable minds.
Raven Sons		The Raven Sons are a Codex-compliant fleet-based Successor Chapter of the Raven Guard created during the Ultima Founding, ca.999 M41. They were created with the task of serving as a buffer force to the Astra Militarum, often being deployed onto the same battlefields to "eliminate" enemy leaders and supply lines. They also support the overall firepower of the forces of the Astra Militarum. The chapter is known for its non-standard recruitment system, often taking young Aspirants from saved imperial worlds, calling them the "warborn", believing these children were born to fight. This often raises disputes within singular squads as it's hard to get people of different worlds and cultures to quickly adapt to the same strategies and views of warfare.
Reaper's Children		The Reaper's Children are a Renegade Space Marine Chapter. Once a selected Battle-Brother joins the Chapter, they swear an oath of loyalty and forgo the livery of their Chapter donning the trademark black and red colours of the Reaper's Children. Comprised of Astartes from several different Chapters and Blackshields, the Reaper's Children specialize in special operations and non-conventional warfare, favoring freedom of maneuver and portability of firepower. In recent years, the turbulence of the galaxy has spread, the High Lords of Terra declaring more and more Chapters Excommunicate Traitoris, many of the so called "Renegade" Chapters are still loyal servants of the Emperor and the deliverers of his wrath. Once operating completely in the shadows, a new force is seen again throughout the Imperium. A nameless chapter of Astartes, clad in the black and red trim of the Reaper's Children. These mysterious warriors emerge from the darkness of the void in small, discreet bands in swift strike cruisers to surge through the stars to cut the throat of the enemies of the Imperium. (Traitoris Perdita) (Note: This Chapter falls under the Alternate Universe category.)
Rebutors		The Rebutors are an ancient, steadfast semi-Codex compliant Space Marine Chapter created during the 4^th Founding, following the aftermath of the infamous War of the Beast in the mid 500's.M32. The Chapter is extremely honorbound, devoted heavily to carrying out tasks and enacting campaigns in honorable manners. Unlike most other Astartes Chapters, the Rebutors value the lives of Imperial citizens, frequently defending them against various threats. This system of belief has earned the Chapter many a disapproval from other Space Marine Chapters of the Imperium, those being more heartless. Similar to that of the Black Templars Chapter, the Rebutors are currently in a Crusade that demands the demise of all aliens and heretics that seek to disturb the might of the Imperium. However, unlike their Black Templars gene-brethren, they are far less extreme and zealous.
Red Axes		The Red Axes are a Loyalist Space Marine Chapter faithful to the Imperium. The Chapter's Founding records, as well as their beginnings, are mostly lost in time; although the only thing that is known is that they are descended from the heroic and noble Blood Angels. Also, most of their campaigns are censored by the Inquisition. Only those who have shared the battlefield relate the events experienced. But now with the incidents in Lothar, this Chapter's brutal practices on the battlefield have been made known throughout the Imperium, which have led to their rejection by other chapters and also of other imperial institutions, generating fear and hatred in both allies and enemies.
Red Crusaders		The Red Crusaders are a loyalist Space Marine Chapter created during the 4^th Founding during the middle centuries of M32 from unknown lineage. This Chapter hails from the Sanctus System, a star system currently lost to the Imperium Nihilus due to the destruction of Cadia and the Cicatrix Maledictum. Like the Black Templars, the Red Crusaders also believe in the divinity of the Emperor, though the question of if its really the Emperor they worship has been brought up many times by Inquisitors.
Redeemed		The Redeemed are a Raven Guard Successor Chapter based on the death world known as 'The Reach'. Though mistrusted by other Space Marine chapters due to their recruitment traditions, the Redeemed are widely recognized as expert pirate hunters and deadly tunnel fighters.
Redeemers		The Redeemers is a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created from the rare lineage of the Raven Guard and raised during the Ultima Founding of ca. 999.M41. Created as a chapter to watch potential new threats coming from outside the Milkyway Galaxy, the Void Watchers keep their eyes in any events enveloping the Eastern Fringe. Their actions usually take them against both Ork forces and Tyranids.
Redemptors		The Redemptors are a Loyalist Successor Chapter of the Imperial Fists, raised in the wake of the Nova Terra Interregnum in the 15^th Founding. Enduring devastating losses at the dawn of M36, the Redemptors were reduced to barely two Companies of Astartes, and have spent the better part of the last six thousand years rebuilding both themselves and their shattered homeworld. Chastened by their failure to save the Hive World of Lachrimorta and its people from devastation by rebels, this Chapter of Astartes has sworn itself to the stewardship and defense of the dying world and its people. They are not a Codex Astartes-compliant Chapter and maintain an organizational structure and Chapter culture that is very unusual amongst the Adeptus Astartes. They venerate the Emperor of Mankind as the One True God of Humanity, believing with a holy fervor bordering on fanaticism in the teachings of the Ecclesiarchy. Following a schism early in their history, The Redemptors have divided themselves into two primary Orders - The Bulwark and The Conclave. The Bulwark is responsible for the defense and protection of the chapter's Homeworld, as well as the surrounding Atropos sector, while The Conclave consists of those Astartes responsible for actions in the wider Imperium. These primary orders are further divided into dozens of Orders Minor, made up of Battle-Brothers of like mind who specialize in certain aspects of warfare such as heavy weapons, vehicular combat or rapid assaults.
Retributors		The Retributors are a Loyalist Successor Chapter of the stoic Imperial Fists, created during an unknown Founding. Since their inception they have continuously stood stalwart in the face of myriad threats to the Imperium of Man, including hordes of foes, cunning witchcraft and terrifying unknown technologies. The Chapter primarily operates along the borders of the Eastern Fringe. This Chapter has been described as distant, relentless and efficient by those fighting alongside them as the Retributors are a stern and austere Chapter, more interested in battlefield success than glory and accolades.
Revealers		The Revealers are an old, proud chapter created during the Third Founding. They are descended from the legendary Imperial Fists and are known for their zealous demeanor and unceasing quest to destroy all enemies of the Imperium, wherever they may lurk. The Revealers have become known as merciless witchhunters and destroyers of heretical cults, which has made them steadfast allies of the Ordo Hereticus, although many see them as the Inquisition's lapdogs.
Revenant Angels		The Revenant Angels were a now-extinct loyalist Chapter descended from the gene-seed of the Blood Angels. Founded during an unknown Founding, the chapter was pushed to extinction in the mid-40th Millenium due to gene-seed flaws. Prior to their extinction, the Revenant Angels were known for drop-pod assaults and mastery of swordsmanship, as was typical amongst the Sons of Sanguinius.
Revenants		The Revenants are an Astartes Chapter of Blood Angels descent, created during an Unknown Founding (but extant evidence points to either the 2^nd or 3^rd Founding). They are a slowly dying Chapter whose numbers are believed to have fallen below 300 Astartes. Though they are very loyal to the Emperor of Mankind their heavy affliction with the twin Flaws of their Primarch Sanguinius has led to their investigation on charges of heresy by the Inquisition. They have been cleared of suspicion at present, but many believe that it is only a matter of time before they cease to exist. Like their Progenitors, the Revenants are known for their bloodthirsty nature in battle, bad temper and fear for the Flaws - the Black Rage and the Red Thirst - that they carry within their gene-seed. The Charnel Brethren follow the tactical organisation pioneered by the Blood Angels, favouring close combat over ranged warfare.
Rift Reapers		The Rift Reapers are an Ultima Founding Space Marine chapter using gene-seed taken from the secretive Dark Angels and their Primarch Lion El'Jonson. They were officially founded in the first wave of primaris chapters during the Indomitus Crusade, though they were part of the pre-founding batches of primaris used for testing the new organs and equipment that were created and deployed in small amounts prior to the actual founding. While at first they were ignorant to much of their primogenitor chapter's true history, by the end of the Indomitus Crusade the chapter's Inner circle was aware of the Fallen and have fervently joined the secretive ranks of the Unforgiven in the hunt for them.
Rondo Knights		The Rondo Knights are a loyalist mostly Codex Astartes-complaint Space Marine Chapter presumingly created during 23^rd 'Sentinel' Founding from the genetic lineage of the Dark Angels to replace a lost minor chapter within the Segmentus Pacificus. They went dark for many years after their sector home planet was covered into a massive warp storm, but they reemerge from the void years later close to full strength and have since then perform their duties zealously hunting heretic and xenos while spreading the Imperial Creed everywhere they go. The Rondo Knights are known to be a very chivalry group: cordial, respectful and honorable, yet complete implacable against their foes. Despite their alleged relation to the Unforgiven Chapter, the Rondo Knights are shunned by most of the Dark Angels' Successor Chapters.
Royal Herculeans		The Royal Herculeans (High Gothic: Regiis Herculii) are a loyalist, semi-Codex compliant Adeptus Astartes chapter raised during the Second Founding, largely drawing its numbers from the XIIIth "Ultramarines" Legion's 32^nd Legionary Company after the close of the Horus Heresy. From its fortress monastery in the Caeniian Sector, within the spinward potion of Segmentum Pacificus, the Royal Herculeans have sworn the safeguard the citizens of the Imperium of Man from all dangers within, without, and beyond. The Herculeans chapter has, throughout its 10,000 years standard-long history, served in countless conflicts across the whole of the Imperium and has maintained a meticulous archive of its achievements as well as those whom they served beside. In that time, the Herculeans have modified its battlefield doctrine and internal organization to better-serve their conquests, earning no small amount of ire from other Scion-chapters of the War-Born.
Ruby Consuls		The Ruby Consuls are a 7^th Founding Successor Chapter of the noble Ultramarines. Operating from their fortress-monastery on their Chapter home world of Tiberiad VII in the Reman Sector, the Ruby Consuls are deployed to battlefields across the galaxy. Although they may not possess the same galaxy-wide renown as the more famous Chapters, the Ruby Consuls nevertheless possess an impressive service record and take pride in their own achievements and honours. While they can be found nearly anywhere in the galaxy, the Ruby Consuls remain attached to the Reman Sector in the same way that the Ultramarines remain attached to the Realm of Ultramar. The Chapter is known for its very "by-the-book" attitude when it comes to the tactical doctrines outlined in the Codex Astartes. The Ruby Consuls possess no deviations from Codex-compliant organizations excepting in cases were the Codex itself allows for flexibility.
Ruby Sabres	Pict-File Unavailable	The Ruby Sabres are a formerly Loyalist Space Marine Chapter created during the 15^th Founding from unknown lineage. The Chapter was known for its close adherence to the Codex Astartes. They defended the Imperium from the countless enemies of Mankind for centuries. Yet one battle-brother would soon make a grave mistake on the world of Thesulia Prime. Now they fight against the Imperium, against those they once swore to protect. They were eventually cast out of the Imperium and declared as renegades and became the notorious Chaos Warband known as the Bloody Hands. A large number of Alpha Legion have found their way into the warband, which the Bloody Hands have accepted with excitement, for any opportunity to sabotage the Imperium that the Alpha Legion uses, the Bloody Hands are glad to assist in. (Excommunicate Traitoris)
Ruiners		The Ruiners are a semi-Codex compliant Space Marine Chapter of the Adeptus Astartes comprised entirely of newly revealed Primaris Space Marines created during the Ultima Founding. They bear the gene-seed of Primarch Ferrus Manus of the grim and unforgiving Iron Hands. While this Chapter does maintain their parent Chapter's close ties with the Adeptus Mechanicus, they do not share in their beliefs in the weakness of the flesh.

Sable Lions		The Sable Lions are a Successor Chapter from the line of Rogal Dorn, supposedly created during the 8^th Founding, which allegedly occurred during mid-M34. This Founding was undertaken amid the dark times of the Nova Terra Interregnum, when the Imperium of Man had been split into twin interstellar empires. The Sable Lions quickly garnered a noble if aloof reputation, even for the warriors of the Adeptus Astartes. For their role during this conflict, they were given the primitive world of Persepolis, located in the galactic north near the Pelegron Cluster, which lies near the edges of the Segmentum Ultima and the Segmuntum Obscurus. They serve as protectors, guarding the Imperial routes to the Forge World of Mezoa, located in the nearby Gothic Sector, while their Chapter starships tirelessly ply the borders of the Pelegron Cluster, hunting down and slaughtering xenos corsairs and potential Chaos incursions that have long made this trackless region their lair.
Sable Pride		The Sable Pride is a semi-Codex compliant successor of the venerable and ancient Dark Angels Chapter, that was founded in order to hunt down a specific Fallen during M37. The Prides' history has been fraught with misfortune and treachery as they have sought to complete their duty to the Emperor and the Lion. The chapter even suffered its own civil war known as the War of the Two Prides, which damaged the psyche of the chapter and caused a slow turn away from the Unforgiven, who they now hold a tenuous relationship with, completely ignoring the word of the Supreme Grand Master and even firing upon fellow chapters. Despite this, the Pride still hunts the Fallen, but places far more importance on capturing their own traitors from the warband, Dothanes Pride.
Sabretooths		The Sabretooths are a notoriously bellicose and savage Successor Chapter created from the lineage of the Dark Angels. Their inception occurred during the ill-fated 21^st Founding, the so-called 'Cursed Founding'. Formerly known as the Lions Revenant, the primitive, half-feral Space Marines that call themselves the Sabretooths are perhaps one of the strangest tales of Chapters spawned by Project Homo Sapiens Novus. Once rising stars amongst the Unforgiven, the savage tribesmen of Storegga are now seen as a baffling example of Inculaba's curse.
Sanctors of Lightrim		The Sanctors of Lightrim were a formerly Loyalist Space Marine Chapter created during an Unknown Founding and of uncertain lineage. They were founded to guard against the threat of the Traitor Legions attacking the Nosgothica Sector from the nearby Eye of Terror. The Sanctors were once counted amongst the most stalwart defenders of mankind. But the insidious threat of Chaos wrapped its corrupting tendrils around the very soul of the Chapter, instilling within the Sanctors' lore-seeking brethren, an unnatural craving for forbidden knowledge. Believing they could defeat Chaos by utilising the power of the Ruinous Power against itself, they were eventually declared renegade and driven into the Eye of Terror, becoming the Chaos Warband known as the Sons of Damnation. (Excommunicate Traitoris)
Sanguine Berzerkers		The Sanguine Berzerkers are a Loyalist Successor Chapter created from the lineage of Sanguinius and his noble Blood Angels. An ancient and laudable Chapter, the Sanguine Berzekers claim to be one of several Chapters created during the Second Founding in 021.M31, following the successful conclusion of the Great Scouring. However, due to the paucity of records, human error and the passage of time, these claims cannot be accurately verified. Following their inception, the Sanguine Berzekers quickly established themselves as a bellicose and savage Chapter, forever prosecuting their neverending war against the enemies of Mankind. But the Sanguine Berzerkers have also garnered a reputation as one of the more savage Chapters of Blood Angels' lineage, for like their Progenitors, the Chapter has a penchant for close-quarters combat and makes heavy use of assault units within their Chapter formations.
Sanguine Chalice		The Sanguine Chalice are a Loyalist Successor Chapter of the vaunted and heroic Blood Angels. Created during an unknown Founding, despite being unable to pinpoint exactly when they were created, it is well known that they possess a long and glorious history, having been pivotal in many victories against the Chaotic horrors that have emerged from the infamous warp rift known as the Eye of Terror. During the recent Devastation of Baal, the Chapter valiantly faced the ravenous hordes of the Great Devourer and was wiped out to a man. However, with the advent of the Ultima Founding and the revelation of the new Primaris Space Marines, this Chapter was re-constituted with this next generation of Astartes. They continue to honour both their Progenitors and their namesake through their heroic deeds.
Sanguine Spears		The Sanguine Spears is a 3^rd Founding Successor Chapter of the noble Blood Angels. Operating from their fortress-monastery of Castello Mazza, the Sanguine Spears are deployed across the Segmentum Obscurus and Segmentum Ultima. Virgil Voltaire is the current Chapter Master of the Sanguine Spears, having served in this position since the twilight years of the 41^st Millennium.
Sanguine Spectres		The Sanguine Spectres are a Successor Chapter of the noble Blood Angels, created during the 25^th 'Bastion' Founding, which occurred during the latter half of M40. They suffered heavy losses during the Devastation of Baal campaign against the Tyranids of Hive Fleet Leviathan, losing their Chapter Master and several companies, including the 1^st, 5^th and 6^th and companies.
Sanguine Templars		The Sanguine Templars are a venerable and ancient Successors Chapter of the sacred bloodline of the angelic Primarch Sanguinius, gene-sire of the the heroic Blood Angels, created during the Second Founding in 021.M31. Formerly, they were known as the 7^th Company of the original IX Legion. The warriors of this company were known to revere the Great Angel above all else, which bordered on worship. Despite the tenants of the non-secular Imperial Truth that was enforced upon newly conquered worlds. However, their resolve was sorely tested during the dark days of the Horus Heresy, when the galaxy was torn asunder, following the subsequent betrayal of the Emperor's most favoured son. Following the end of the Horus Heresy and the subsequent Great Scouring, the Space Marine Legions were sundered into separate Chapters. Recognised for their stalwart and dedicated service, the 7^th were granted the honour of forming their own Chapter - the Sanguine Templars. Following their inception, they immediately departed Terra, vowing to undertake a perpetual Crusade, in order to bring the light of the Emperor to the darkest corners of the galaxy.
Saurians		The Saurians are a loyalist Successor Chapter of the Salamanders. They claim to have been created during the 25^th 'Bastion' Founding. Those precious few who consider the reclusive Chapter an ally attest to their complex nature: the Saurians choose battles shrewdly but, should they respond to distress, commit so strongly they are often last to leave the field; the Saurians care deeply for Humanity, striving to minimize collateral damage and death whenever possible, but will not lift a finger to help ravaged worlds rebuild; the Saurians work closely with the Adeptus Sororitas and several Astartes Chapters which adhere to the Imperial Cult, but are themselves staunch disciples of the Imperial Truth.
Scar Hounds		The Scar Hounds are a Renegade chapter of the Adeptus Astartes founded during M36, during the ill-fated 21^st 'Cursed' Founding. Their genetic forefathers are lost to time and up until this day none but the Inquisition know their true genetic ancestry. Being branded Excommunicate Traitoris in 449.M37, the Scar Hounds now act on their own, doing what they consider to be the Emperor and Spirit of the Hunt's bidding. (Traitoris Perdita)
Scarlet Blades		The Scarlet Blades are a Loyalist Space Marine Chapter that is semi-compliant to the Codex Astartes. They were created from the lineage of the honourable Ultramarines during the 23^rd 'Sentinel Founding'. They hail from the mining world of Calvary and their base of operation is the sky-high, golden tower called Torre del Águila. They specify in the discovery, exploration and conquest of unintegrated planets within or without the Imperium's borders. Recently, a lot of criticism has been targeted at the Chapter, since many claim them to be little more than ruffians for the Inquisition, as they tend to get an above-average amount of support and positive attention from said organization. Also because of their close relationship with the Inquisition, many agents can count on the protection and service of the Scarlet Blades when other Space Marine Chapters would be hesitant or suspicious. The Scarlet Blades are also infamous for their extreme love for luxury and artistic beauty, especially anything to do with gold, having sometimes made very questionable decisions for the pursuit of valuable trinkets.
Scarlet Constrictors		The Scarlet Constrictors are a Loyalist Successor Chapter created from the lineage of the noble and ancient Salamanders Chapter, created during the 23^rd Founding, the so-called 'Sentinel Founding' during the early centuries of M39. This Chapter hails from the planet Bograx, a death world located in the Bothror'a System. As the surface of this verdant world is entirely covered by dense jungles, immense grasslands and a plethora of deadly flora and fauna, the inhabitants of this world have to live inside underground bunkers. The Scarlet Constrictors' beliefs are relatively similar to that of their progenitors, with one glaring difference - instead of going out of their way to protect innocent civilians they always try to annihilate the enemy first. They believe it is better to suffer the loss of a thousand innocents but slay the enemy rather than to suffer no loss but fail at what they were made to do - which is to eradicate Mankinds' foes.
Scarred		Known amongst the Imperium of Man as the 'Wolves of Jochi', the Scarred are a wild and frenzied 3^rd Founding Successor Chapter of the White Scars. Infamous for the almost elemental devastation their presence brings to the battle, having embraced their ancestral war-frenzy driving, the brooding Scarred allow it to propel them ever onward like the bone-chilling storms of the tundral Jochi. Like their progenitors, the Scarred are masters of lightning-fast assaults, appearing suddenly in bellows of fury, their coming heralded by the skies darkened and unnatural blizzards beginning to lash the battlefields.
Scions of Cassan		The Scions of Cassan are a loyalist Successor Chapter of the vaunted Ultramarines, raised in the 35^th Millennium. Initially lauded by those they defended, their achievements were seemingly never acknowledged or rewarded by the Imperium, and by the 40^th Millennium they had been all but forgotten by the Imperium despite still stalwartly defending humanity. It was during this millennium that the reason behind this mystery was revealed, and the Chapter gained a new lease of life.
Sea Kings		The Sea Kings are a loyalist completely Primaris Space Marine Chapter of the Ultima Founding, descended from the fearsome and wild Space Wolves. They are particularly unique amongst the Vlka Fenryka for not only they way they wage war, but also for their mannerisms and even recruitment amongst the population of their homeworld of Fjord. Their primary tactic involves swiftly and violently raiding an enemy outpost, village, or sometimes even stronghold before disappearing back into the mist from whence they emerged upon their mounts or the many hover transports they employ. Over and over they shall do this, always picking off the weakest of the enemy forces and drawing the strongest away from the rest of the horde to be hacked apart with no hope of reinforcement. All the while, they chant haunting songs and battle prayers in their native language, filling the mist that seems to constantly surround them with the voices of a hundred ghosts. Eventually, once the foe has been sufficiently weakened, they will strike the killing blow, screaming out of the fog and celebrating in the aftermath for all to see, their foes skulls taken as trophies to be mounted upon their vehicles.
Sea Serpents		The Sea Serpents are a non-Codex compliant Chapter of Space Marines whose exact Founding and lineage are unknown, although some Imperial scholars hypothesize their origins harken back to the dark days of the Horus Heresy to a similarly named Loyalist Blackshield force. Known for their use of terror tactics, infiltration and asymmetrical combat strategies, they've made a name for themselves as a fearsome and elusive tool of the Imperium that swiftly destroys their enemies before they can even mount a defense.
Sentinels of Blood		The Sentinels of Blood, a successor chapter of the Blood Angels from the Ultima Founding, were originally a task force of the Blood Angels but were stuck in a warp storm for an unknown period and emerged from the warp storm guided by a mysterious angelic figure before the Devastation of Baal, where they fought bravely, though they suffered heavy losses. In the aftermath, Commander Dante sanctioned their establishment as a new chapter under his blessing, utilizing reinforcements from Roboute Guilliman. They established themselves on the temperate planet Crinovia in the Astralith Expanse, specializing in shock-assault tactics and close-quarters combat. Devout in their belief in the Emperor's divinity.
Seraphim of the Abyss		The Seraphim of the Abyss are a mysterious and ancient semi-Codex Compliant Dark Angels Successor Chapter from the 2^nd Founding, and thus members of the Unforgiven, Scions of the Lion that hunt the Fallen Angels. Once, the Chapter was named the "Seraphim of the Gryphon" until tragedy struck these sons of the Lion when their beloved home-world was destroyed, like Caliban of old, and now restlessly engage in the Hunt for the Fallen. They also have developed their own distinct culture and beliefs over the millennia inhabiting the planet that was once heralded as a "New Caliban." Due to the specialties of the Boletarian recruits uplifted to the Chapter, the Seraphim have developed either a love or a deep appreciation for hunting, whether it be the traitorous Fallen or a particularly deadly xenos species. However, their own separate cultural traditions have created a chasm of animosity between them and their fellow Unforgiven Chapters.
Seraphs Sanguine		The Seraphs Sanguine are a Loyalist Successor Chapter of the Adeptus Astartes that were created during the 20^th Founding from the heroic lineage of the First Founding Blood Angels. Their fortress-monastery 'The Shard' is located on the glassy desert death world of Agrito.
Sermo Invictus		The Sermo Invictous Chapter is a Loyalist, non-Codex compliant Space Marine Chapter drawn from unknown lineage and created during an unknown Founding, though their Founding could have been no later than the 3^rd Founding due to their appearance in the War of the Beast in 544.M32. Many believe the Chapter is a fervent offshoot of the already zealous Black Templars, while others believe there is a darker past to this Chapter's origins, possibly making them related to the hated Word Bearers Traitor Legion.
Shades of Cog		The Shades of Cog are a semi Codex-compliant Space Marine Chapter believed to have been raised as part of the 11^th Founding in 900.M35 in response to the extreme civil conflict and unrest in the Imperium. The chapter was created to assist their White Scars ancestors in countering the threats in the Segmentum Ultima.
Shadow Monarchs		The Shadow Monarchs are a Loyalist Successor Chapter of the Raven Guard. They were formed during the 4^th Founding and have participated in a number of important conflict, including three of the thirteen Black Crusades, the Third Tyrannic War, the Parrotgulf Crusade and the War of the Great to name a few. For all of the great battles that the chapter have been involved in and all the battle honours collected by various members of the chapter, the Shadow Monarchs are a fairly unknown chapter in the wider scheme of things. They have always given credit to their allies in their battles, preferring to stay in the shadows. Their method of war reflects this. Any enemy that the Shadow Monarchs deem important never live to tell the tale.
Shadow Phantoms		The Shadow Phantoms are a Loyalist Space Marine Chapter created during the mysterious 13^th Founding, to so-called 'Dark Founding'. Their origins are unknown, though there is reason to believe that they are descendants of the mysterious chapter, Zero Legion. Once they were known as the Shadow Knights, but following the near destruction of the chapter, they've changed their Chapter name and ways. The Chapter is also known to offer their services to Inquisitor Alexander Zackery, and have been well respected by the various Imperial Guard Regiments they have worked alongside with.
Shadow Revenants		The Shadow Revenants are a Loyalist Chapter that hails from the planet of Umbra located in the Segmentum Obscurus. They were created in the recent Ultima Founding as one of the Successor Chapters of the Raven Guard. The chapter's gene-seed has resulted in battle-brothers suffering from some mutations which include pale, ghostly complexions and unnaturally luminescent eyes. These mutations have resulted in the Chapter being called the Shadow Revenants, as these mutations reflect the battle-brothers' abilities to strike from the shadows as well as their ghostly visage.
Shadow Talons		The Shadow Talons are a 4^th Founding Successor Chapter of the heroic Raven Guard, created sometime in the fifth century of M32. Little is known about this Chapter in official Imperial records save that the Shadow Talons are known to be a reclusive and suspicious Chapter, who no longer trust other Space Marine Chapters or the Imperial government, preferring to work alone and unobserved by all, save the foes of Mankind and the Emperor.
Shadow Warriors		The Shadow Warriors are a brutal Raven Guard Successor Chapter that was created during the 24^th Founding, sometime in early M38. Hailing from the verdant jungle world of Rehua I, located in the Ultima Segmentum, the Shadow Warriors have been ranked among the most brutal and fearsome of the Raven Guard Successors. Inheriting their strategic prowess from the Raven Guard, the Shadow Warriors combine vicious assaults with cunning tactics and guerrilla warfare, exploiting the enemy's weak spots with lightning fast deployment and finishing them off with brutal efficiency. While these marines inherit the logistical aspect of their battlefield doctrine from the Raven Guard, they carry on the violent and cunning traditions of the tribes of their home world. Many observers often remark on the terrible suffering they bring to their enemies, utilizing close combat brutality to tear apart xenos and heretic alike.
Shadow Wolves		The Shadow Wolves are a newly reconstituted Successor Chapter, comprised entirely of Primaris Space Marines. This Chapter was created from various gene-seed of Primaris Space Marines that made up the ranks of the Unnumbered Sons, which were derived from various Chapters whose genetic lineage hailed from the stoic and proud Imperial Fists. In their original iteration, the Shadow Wolves were a proud Successor Chapter, created during an Unknown Founding, that were also created from the lineage of the Imperial Fists' Primarch Rogal Dorn. Unfortunately, their long and glorious history would end in tragedy in 987.M41, when their Chapter homeworld of Varadon was overrun by the foul xenos bioforms of the ravenous Tyranids. (Note: This Chapter falls under the Expanded Universe category.)
Shattered Star		The Shattered Star are a Loyalist Space Marine Chapter believed to have been created from unknown lineage during the 21^st Founding, the so-called 'Cursed' Founding sometime during M36. Despite the rampant mutations or various idiosyncrasies that inevitably affected most of the Chapters created during this Founding, the Shattered Star's gene-seed remains relatively unaffected by these genetic curses that plague their 'Cursed' Founding brother Chapters.
Shenandoah Knights		The Shenandoah Knights is a Loyalist Successor Chapter created from the lineage of the vaunted and stoic Imperial Fists during the 25^th Founding, the so-called 'Bastion Founding'. A fleet-based Chapter, the Shenandoah Knights lay no claim to any one world. However, they have appointed themselves as guardians of the Shenandoah sub-sector located in the Segmentum Obscurus. Maintaining a network of chapter keeps throughout the sector, these stalwart defenders have stood silent vigil over their chosen demesne for millennia protecting it from threats both within and without. Like their progenitors, the Shenandoah Knights are also believers in the divinity of the God-Emperor, and as such, they maintain strong ties with the Ecclesiarchy as well as a close relationship with the Adepta Sororitas, most notably, the Order of the Emerald Rose. However, due to their adherence to the Imperial Creed, they often clash with other Chapters of the Adeptus Astartes who do not share their beliefs.
Shields of the Void		The Shields of the Void are a loyalist semi Codex-compliant Successor Chapter created from the lineage of the proud but brutal Iron Hands Space Marine Chapter during the 4^th Founding. This Founding occurred following the events of the near-disastrous War of the Beast which laid waste to the galaxy and had even threatened the security of Terra itself.
Sigma Aons		The Sigma Aons are a Loyalist Space Marine Chapter of the Adeptus Astartes originally created during the mysterious 13^th Founding, known as the mysterious 'Dark Founding', from uncertain genetic lineage. Unlike other Astartes Chapters, the Sigma Aons are unusual as they maintain two Chapter Masters at the same time. The effect this had upon its unusual Chapter hierarchy remains unknown. The Sigma Aons recruit from both their Chapter homeworld - the feral Jungle World of Tephek - and the Hive World of Canid One, though their reasoning seems to suit with their organization.
Silver Centurions		The Silver Centurions are a loyalist Codex-compliant Successor Chapter that hails from the proud lineage of the honorable Ultramarines. This Chapter was supposedly created during the mysterious 13^th Founding (known also as the 'Dark' Founding), under commendation of the High Lords of Terra and Chapter Master Ollonius of the Ultramarines, following a successful campaign to restore the Euridite Sector at the edge of Segmentum Tempestus. This highly organised Chapter is known to recruit their members on both Penal and Hive Worlds across the Segmentum Tempestus, picking troubled youths and young hive scum gangers to become Angels of Death. The Silver Centurions are a fleet-based Chapter who continuously patrol across the width and breadth of the galaxy, to take the fight to the enemies of mankind before they become a dire threat.
Silver Fists		The Silver Fists are a Chapter formed of Primaris Space Marines created from Rogal Dorn's gene-seed, who served as part of Roboute Guilliman's Unnumbered Sons during the Indomitus Crusade. After the Avenging Sons's Crusade ended, the Silver Fists were formed and relocated to Sebastus VI, were they began recruiting and strengthening their numbers. Having studied the tactics of the Imperial Fists, the Crimson Fists and even the Black Templars chapters that were available, they began to develop their own strategies to intervene in both xenos and traitor attacks on populated worlds and valuable locations.
Silver Flames		The Silver Flames, originating from the 21^st "Cursed" Founding, their lineage remains shrouded in mystery. Lay claim to both Salamanders and Iron Hands heritage, their gene-seed intertwined with the essence of Vulkan and Ferrus Manus. However, behind their noble facade, the Silver Flames harboured a dark secret. Embracing the Mercurial Cult, a twisted interpretation of the Promethean Cult mingled with Iron Hands' beliefs, they believed in the purifying power of flame. As their beliefs spiralled into extremism, the Silver Flames' relentless pursuit of perfection led to their eventual undoing.
Silver Hands		The Silver Hands ('Manus Argenti' in High Gothic) are a Chapter from unknown lineage, founded during the mysterious 13^th 'Dark' Founding as a fleet-based chapter. Following a nomadic pattern, their role is to reinforce other imperial forces in time of need on the battlefield. Stoic and proud, they are also known for being merciless and sometimes excessively violent.
Silver Heralds		The Silver Heralds - known for much of their history as the 'Heralds of Wrath' - are a 3^rd Founding Successor Chapter of the Angels Vermillion, effectively reborn during the Ultima Founding as an all-Primaris Chapter. At their best, they are an exceedingly humanitarian order with a prevailing belief in the power and destiny of humanity and their own prime duty to lift the Imperium's citizenry by example. 10,000 years of darkness and war would shake and reshape their beliefs, taking them to dark places before a most unlikely salvation during the Era Indomitus. The Silver Heralds are a case of both the glory and the tragedy that dogs the gene-line of Sanguinius.
Silver Lions		The Silver Lions are a honourable and venerated 3^rd Founding Successor Chapter created from the lineage of Lion El'Jonson who refused to adhere to the strictures of the Codex Astartes. Much like their brothers in the Unforgiven, they too take part in the Hunt for the Fallen and pursue their most hated foes relentlessly in order to clear the name of their primogenitors and by extension their own.
Silver Shards		The Silver Shards are a Loyalist Space Marine Chapter descended from the Primarch Rogal Dorn and successors to the honourable and proud Imperial Fists Chapter, with their founding being held during the 4^th Founding in the 500s.M32. Currently, the Silver Shards are a fleet-based Chapter, with its main operation being in northern Segmentum Ultima, however, several crusades have been declared prior and presently that took the Chapter into the Eastern Fringe and Segmentum Obscurus, where the ruins of their homeworld reside.
Silverbacks		The Silverbacks are a Loyalist Space Marine Chapter of unknown Founding and lineage. It is believed that they were created during the 9^th Founding. Their fortress-monastery is located on the jungle Death World of Wazari II between the borders of the Segmentum Obscurus and Segmentum Pacificus. The Astartes of this Chapter are notable for being unusually large and robust physical specimens, even amongst their kind, and they are capable of surviving wounds and physical injuries that would kill even other Space Marines. Very little information is recorded about this Chapter in official Imperial records.
Sin Eaters		The Sin Eaters are a non-Codex complient Successor Chapter of the ancient and honourable Blood Angels, created during an Unknown Founding. They are noted as a highly superstitious chapter, holding the curses of Sanguinius's gene-seed with religious reverence. It is their belief that, by interpreting the mad ravings of those afflicted with the Black Rage, the chapter can glean insights into the lingering grace and wisdom of their primarch.
Sin Seekers		The Sin Seekers are a Loyalist Space Marine Chapter of unknown lineage, produced somewhere around the 19^th Founding. They are highly proficient hunters of Heretic Astartes within the ranks of the Adeptus Astartes, tracking their fallen cousins across the galaxy and ending them justly. Their unending-crusade of seeking their quarry far outweighs assisting their fellow Loyalist Chapters, making them disliked by most Chapters aware of their existence.
Skull Reapers		The Skull Reapers are an Astartes Chapter of suspected Iron Hands descent created during an unknown Founding, but are suspected to be a Chapter of the mysterious 21^st Founding, the so-called 'Cursed Founding', as they are extremely similar in appearance to the mysterious Sons of Antaeus Chapter. The Astartes of the Skull Reapers Chapter are unusually large and robust physical specimens, even among their kind, and they are capable of surviving wounds and physical injuries that would kill even other Space Marines. The Chapter's detractors point out that the Skull Reapers appear every bit as resilient as the Death Guard Traitor Legion and some have even opinioned that they are somehow connected to them, but this is an impossibility as the Skull Reapers were created thousands of years after the Horus Heresy and have, on many occasions, willingly submitted themselves to the mandatory purity tests of their gene-seed which has seemingly confirmed their status as an Iron Hands Successor Chapter.
Skull Takers		The Skull Takers are a notoriously bellicose and vicious Loyalist Space Marine Chapter created during the 11^th Founding sometime in mid-M35, that believes itself to be a Successor Chapter of the notorious Executioners. The veracity of the Skull Takers' bold claims of being inheritors of this merciless Chapter have yet to be substantiated. Like their supposed progenitors, the Skulls Takers earned their moniker by taking the skulls of particularly noteworthy victims as trophies from the battlefield. Imperial scholars have surmised that the Skull Takers see the head of a foe to be of significant importance. Only by taking the lives of the enemies of the Emperor, can a Skull Takers Axe-Brother be granted the honour of a place within their Chapter's chronicles.
Smilodons		The Smilodons are a loyalist non-Codex compliant Space Marine Successor Chapter created from the lineage of the proud and feared White Scars of a Unstated Founding in M36. The Chapter was created during the appalling period called the Reign of Blood, when the Renegade High Lord of Terra Goge Vandire gained control over the Adeptus Ministorum, Adeptus Administratum and became the Ecclesiarch. This resulted in massive purges and assassinations of countless of innocent Imperial citizens. In the end, Goge Vandire was executed for his crimes against the Emperor and the Mankind, by the Daughters of the Emperor Matriarch Alicia Dominica.
Snow Lions		The Snow Lions are a Loyalist Space Marine Chapter of the Adeptus Astartes and a Successor Chapter of the proud and stubborn Imperial Fists. Created during the 25^th Founding, or 'Bastion Founding', in 501.M41. The Snow Lions have a short (comparatively) but violent history. A fleet-based chapter created for the purpose of safeguarding an endangered Imperium, the Snow Lions have faced off against a myriad of Mankind's enemies. Their heavy use of armoured vehicles has helped to keep losses to a minimum in a time period where safety was never assured. A fleet-based Chapter, the Snow Lions are highly active in prosecuting their wars against the Forces of Chaos.
Soaring Angels		The Soaring Angels are a Loyalist Successor Chapter of the noble Blood Angels that were created during the 25^th 'Bastion Founding' in M40. A fleet-based Chapter, they strive to embody the aspect of flight and virtue of freedom that their liege-father Sanguinius set as an example to strive for. Like any other son of the Angel, flight whether by aircraft or upon roaring jump pack is a sign of devotion to their Primarch as it lets them feel as he would've felt upon the battlefield, soaring across the sky to bring down destruction upon mankind's enemies.
Soaring Chalice		The Soaring Chalice are a former Loyalist Space Marine Chapter, originating from the Blood Angels and currently known as the Foetid Seraphim Chaos Warband after turning to Chaos during late M37. The Foetid Seraphim worship the Chaos God Nurgle and thus most of the members are hideously deformed and riddled with disease. Currently, they mainly utilise shock tactics in order to win battles, deploying their infamous Blight Bringers and Butchers of Atrophy in order to break their enemy's morale. Currently, they roam the galaxy almost aimlessly, leaving rotting husks of the planets they visit. (Ecommunicate Traitoris)
Solar Falcons		The Solar Falcons are a venerable Successor Chapter created from the lineage of the wild and unforgiving White Scars during the Third Founding in 001.M32. The initial members were drawn from the few surviving Terran-born Astartes. To this day they still recruit from the continent of Europa but keep their Fortress-Monastery elsewhere on a small planet in the Segmentum Solar. This Chapter is mostly utilised to explore and subjugate unexplored parts of space, bringing any human empires into Imperial compliance and wiping out all xenos found. They are known for having an overly savage nature for warfare and for their strict adherence to the Imperial Creed compared to most other Adeptus Astartes Chapters. Both were born from being deployed alongside the crusading Black Templars during an early chapter-wide assault on an unnamed Chaos-held world.
Solar Leopards		The Solar Leopards are a Codex Astartes-Compliant chapter from the Ultima Founding. They are a successor chapter of the White Scars, and their battle style reflects their gene-seed origins. Like their forebears, the Solar Leopards are highly mobile and specialize in lightning-fast aerial assaults that disrupt enemy lines and sow confusion. The chapter is known for its adherence to a code of honor and martial discipline. They are inspired by ancient traditions and beliefs that emphasize courage, duty, and sacrifice. These traditions are drawn from the rich cultural heritage of the people of Jikivar, which has long been a center of learning and scholarship in the Imperium.
Solar Paladins		The Solar Paladins are a Codex-compliant Space Marine Chapter of the 6^th Founding, created from the lineage of the highly vaunted Ultramarines. Based upon the world of Helios, they primarily patrol and protect the Ionian Sector within the Segmentum Tempestus, a large producer of precious metals and gemstones that are shipped throughout the Segmentum. They are a Loyal Chapter, yet have little patience for nosy imperial bureaucrats and have often butted heads with forces of the Adeptus Ministorum. However, they are generally friendly to any Astra Militarum regiments they fight alongside and will protect refugees within warzones with fervor, refusing any harm to them, even by their allies. Thanks to them coming to blows with several of the more fanatical Astartes chapters, the Solar Paladins are often distrustful of other chapters, and will view their fellow Astartes or Primaris allies with suspicion at best, and borderline hostility at worst.
Solar Phoenixes		The Solar Phoenixes are a Space Marine Chapter of unknown origin. Records indicate they were likely created during the 21^st Founding , or the 'Cursed Founding'. While only being slightly larger than the average Firstborn Space Marine, they are somewhat stronger and can match their Primaris counterparts under certain circumstances due to mutations in various organs. They largely act as defensive force in the Segementum Tempestus, operating out of their Chapter home-world of Argentus Tempest. They frequently aid Imperial planets against xenos and chaotic incursions, burning the invaders to ashes. In battle, they are known for their Skyfire and Infernus doctrines, where they use flame and melta weaponry alongside aerial superiority and drop-pod assaults to deadly effect.
Solar Spectres		The Solar Spectres are a mysterious and merciless Space Marine Chapter created during the recent Ultima Founding. Created from the lineage of the wild and untamed White Scars, this Chapter is comprised entirely of newly revealed Primaris Space Marines. Like their progenitors, the Solar Spectres continuously roam the galaxy, stalking the various battlefields across various warzones, delivering swift and brutal death to those that would dare assail the worlds of the Emperor.
Solar Titans		The Solar Titans are a Codex Astartes-compliant Chapter created during the recent Ultima Founding at the end of the Indomitus Crusade. They descend from the lineage of the stoic Primarch Rogal Dorn and, as such, are not particularly known to withdraw from battle, due to their stubbornness. These noble soldiers are settled in the feral world of Palyphomas, the fifth planet of the Centurion System, located in the Ultima Segmentum. The mostly jungle world borders the far end of the T'au Empire, a fact that coupled with its rich mineral and biochemical resources, make its defense highly desirable.
Solar Wolves		The Solar Wolves are an Astartes Chapter of Unknown Founding and descent but speculation is that they are one of the unrecorded Second Founding Chapters, as they are noted to have fought during the Teclis Campaign during M32. They are a semi-Codex chapter in that they follow many of the tenets laid down by the Primarch Roboute Guilliman but are not bound to it as many are, rather it is a guide to be added to or ignored as the situation warrants. They do not follow any one particular combat doctrine but rather strive to excel at any battle they are called upon to fight.
Sons of Achilles		The Sons of Achilles are a 3^rd Founding semi-Codex compliant Chapter dating back to the start of the 32^nd Millennium. They are currently based in the Trojan Sector of the Segmentum Obscurus, dangerously close to the newly formed Cicatrix Maledictum. Records of their gene-lineage have been lost to time, though they themselves claim Roboute Guilliman as their gene-father. The Ultramarines themselves have yet to acknowledge this.
Sons of Athena		The Sons of Athena are a loyalist Ultima Founding Successor Chapter of the heroic Ultramarines Chapter. The Sons of Athena are knowledge seekers and like to keep their activities secret. They take their name from the myth of the old Terra civilization called the Grecians and the goddess known for wisdom, handicraft, and warfare. Known to report only to the Ultramarines Primarch Roboute Guilliman and Belisarius Cawl. Most unusual for an Ultramarines Successor Chapter, they are not Codex-compliant, but due to the activities of the chapter, the Primarch looks the other way.
Sons of Cerberus		The Sons of Cerberus are a loyalist Space Marine Chapter of the Adeptus Astartes created during an Unknown Founding and from obscure origins. Despite the paucity of records,Italic there is very little mention of this obscure Chapter in official Imperial records. However, Imperial scholars believe this ancient Chapter's origins harkens back to the 31^st Millennium following the disastrous events of the galaxy-wide conflict known as the Horus Heresy, though this has yet to be substantially proven. A bellicose Chapter, the Sons of Cerberus are masters of shock assault and melee warfare as well as experts in siege tactics and boarding assaults. Once unleashed against the foe, they will not stop until they have ravaged their enemies into unrecognizable hunks of bloody meat.
Sons of Enlightenment		The Sons of Enlightenment are a Loyalist Space Marine Chapter that was created during the ill-fated 21^st 'Cursed' Founding in 991.M35 from uncertain genetic lineage. They suffer from a genetic flaw of the Catalepsean Node that prevents them from sleeping. The only relief that the members of the chapter receive is the psycho-trances that the chapter's Librarians routinely send them into. A deep sleep-like state where visions both truthful and false are often seen. This genetic mutation is also believed to produce some level of psychic tendency, with all recruits showing at least minimal levels of psychic activity after implantation.
Sons of Helios		The Sons of Helios is a loyalist Space Marine Chapter of the 23^rd 'Sentinel' Founding. They are said to be Salamanders' successors due to their affinity for fire but this is unknown. The Sons of Helios have fought all over the Imperium defending its citizens from the xenos, the heretic and the mutant. The Sons of Helios are unique as they believe in the Emperor's divine authority and see the sun as his symbol. The history of the Sons of Helios Space Marine Chapter is a tale of unwavering loyalty, fierce determination, and the unyielding pursuit of the Emperor's light. From their founding to their numerous campaigns, the Chapter has left an indelible mark on the annals of the Imperium. Coming from the homeworld of Pyros, a desert planet which is unusually close to the sun, the Sons of Helios see the sun as the symbol of the Emperor's might and strive to bring that light to the rest of the Imperium. They see themselves as the shield that defends the weak and have a high concern for civilians in war zones. This concern for lesser beings places them in the succession line of the Salamanders chapter. The Sons of Helios also have an affinity for fire as they see it as the holy weapon of the sun and therefore the Emperor.
Sons of Iron		The Sons of Iron Chapter is a 26^th Founding Successor Chapter of the Iron Hands. Hailing from the perilous world of Suami, the Sons have begun to gain a reputation, among the kin of Ferrus Manus, as an effective Chapter, whose sole and yet infamous stain is their beliefs tantamount to heresy in the eyes of the Iron Hands and many of their successors, while the Imperium at large consider them as a cold and unforgiving gathering of devoted Space Marines, exemplifying the better traits from their Progenitor without the strained relationships which are often the lot of Ferrus Manus lineage. Like all those who bear the Seed of Manus, they feel the drive to replace their flesh with bionics, but try to resist it, a strain which adds to their already grim demeanour.
Sons of Midas		The Sons of Midas is a Loyalist Space Marine Chapter of the Adeptus Astartes created during the 2^nd Founding from the proud lineage of the heroic and much-lauded Ultramarines. Masters of the lightning-fast armoured assault, their Chapter armoury boasts a higher number of armoured vehicles than many other Space Marine Chapters. Many of these vehicles are ancient war relics that have fought for the Sons of Midas since their inception. The Sons of Midas's name has become a byword for armoured assault across the Ultima Segmentum, which serves as its primary area of operations.
Sons of Neptune		The Sons of Neptune are a Succesor Chapter of the White Scars, created during the 23^rd 'Sentinel' Founding. A Chapter that feels as at home in the vastness of the Void, as they do on the waves, they are known for their swift assaults, crashing against enemy forces like an unrelenting tsunami, pushing until their mission is complete and washing all aside to complete their objectives.
Sons of Odin		The Sons of Odin are a Loyalist Successor Chapter believed to have been created during the 3^rd Founding in 001.M32. The Astartes of this Chapter are the proud scions of Roboute Guilliman, the Primarch of the Ultramarines. Though they share little in common with their forebears' culture and traditions, they have garnered a reputation for their unbreakable sense of honour and a history of unparalleled skill at arms. In battle, their ferocious mien has often seen them carry the day, when all odds have been stacked against them. The Sons of Odin are unafraid of battles of attrition or mutual destruction, relying on the abilities of their Battle-Brothers to overcome and endure anything the enemy can throw at them. At times this has proven to be a flaw, as the Chapter has a predilection to fight on once engaged where its better strategic judgment might have otherwise prevailed before its bloodlust was roused.
Sons of Praetoria		The Sons of Praetoria are an Imperial Fists Successor Chapter of the Ultima Founding, originally formed of Primaris Space Marines created from Rogal Dorn's gene-seed, they initially served as a part of the legions of the Unnumbered Sons under the direct command of the resurrected Ultramarines Primarch Roboute Guilliman, who was now the acting Lord Commander of the Imperium. They helped play an instrumental role in the subsequent reinforcement of the Blood Angels Chapter homeworld of Baal, and helped the Sons of Sanguinius drive back the threat of the ravenous Tyranids of Hive Fleet Leviathan. Following this victory and installation of Lord Commander Dante as Regent of the Imperium Nihilus, some of the Primaris that were descended from the lineage of Rogal Dorn were chosen to stand up a brand new Chapter. In honour of their newly appointed Chapter Master, they were dubbed the Sons of Praetoria.
Sons of Rapture		The Sons of Rapture are a Loyalist Successor Chapter of the stoic and unforgiving Iron Hands. Created during an Unknown Founding, they were created from an exiled group that went their separate ways after a disagreement on the Iron Hands' ideals. Stubborn and honourable to a fault, they'll wage war on mankind's enemies wherever is required. learning what they can from the enemy as so to destroy them all the better.
Sons of Zeus		The Sons of Zeus are a loyalist Space Marine Successor Chapter of the stalwart and stoic Imperial Fists created during the 7^th Founding. However, some of their gene-seed share some other qualities from another unknown Primarch. These other genetic traits are suspected to have been inherited from the Ultramarines Primarch Roboute Guilliman, but inconsistencies recently with the newly received Primaris gene-seed have proven otherwise. It is now generally believed that some of their genetic heritage is shared with the White Scars Primarch, Jaghatai Khan. With this mixture of gene-seed, the Chapter is known to favour both stalwart defensive and rapid offensive tactics, often making it seem like a wave forcing sand to crash into an immovable wall. So this chapter specializes in mounted warfare, aerial and naval warfare, defensive warfare, and siege warfare as well as supporting a series of specialized combat teams similar to the Kill-Teams utilised by the xenos-hunting Deathwatch. Even sometimes donating its members to the Deathwatch and further studying them to see how they might improve against the foe.
Sons of the Creed		The Sons of the Creed are a Codex-compliant Chapter created during an Unknown Founding from the lineage of what is usually assumed to be that of the vaunted Ultramarines. This assumption is due to both their astrographical closeness to Ultramar as well as the numerous occasions down the millennia they have fought alongside the Scions of Guilliman. A lauded and honorable Chapter, the Sons of the Creed have fought the foes of Mankind since at least M33, standing as a bulwark against the myriad of threats that assail the Imperium, both from without and within.
Sons of the Basilisk		The Sons of the Basilisk are a Dark Angels Successor Chapter, formed during the ill-fated 21^st "Cursed Founding". The chapter has only recently reformed after being marked as heretics by the Inquisition after their original chapter master, along with a large majority of the chapter, gave themselves over to the Chaos God of Pleasure, Slaanesh. The chapter are infamous for their prideful nature and nobility.
Sons of the Emperor		The Sons of the Emperor are a Loyalist Successor Chapter of the fanatical zealots known as the Black Templars, who in turn descend from the stalwart Imperial Fists, the VII Legion of old. Created during the 4^th Founding, this Chapter is considered excessively religious even by the standards of other Space Marine chapters, the Sons consider every aspect of their lives to be watched carefully by the God-Emperor, and they devote every single moment of their days and nights to honoring this belief. When resting in their fortress-monastery, the Halls of Faith, these Astartes pray continuously, stopping only in the few occasions when a superhuman member of the Adeptus Astartes must sleep. In times of war, every bolt shot, every sword strike and every tactical decision are made while a quiet pray is being intoned, making sure that their supreme deity is always pleased by their actions.
Sons of the Night		The Sons of the Night are a Chapter of the Adeptus Astartes of unknown origin. They specialize in suppressing rebellious Imperials worlds, and are notorious for unparalleled acts of cruelty while doing so. These practices have caused a great deal of suspicion from other Imperial entities, though a thorough Inquisitorial investigation has concluded that they are indeed genuinely loyal to the Imperium despite their questionable methods.
Sons of the Void		The Sons of the Void are a Loyalist Space Marine Chapter created during the 23^rd 'Sentinel' Founding during the latter centuries of M37. Imperial scholars believe they were created from the proud lineage of the honorable Salamanders Chapter. They were one of several newly incepted Chapters created to help form a bulwark against encroaching xenos, especially along the frontiers of the Segmentum Pacificus against raiding Orks and the newly awakened Necron menace.
Sons of the Wyvern		The Sons of the Wyvern are a Loyalist Space Marine Chapter created during the ill-fated 21^st Founding, the so-called "Cursed Founding", due to the high rate of genetic idiosyncrasies and mutation that ran rampant amongst the Chapters created during this particular founding. Officially their heritage is unknown, however, the Sons of the Wyvern are highly suspected of being descended from the genetic lineage of Jaghatai Khan. However, routine examination of their genetic tithe by the Magos Bioligis has found genetic markers within their gene-seed that indicate that it was somehow adulterated or mixed with gene-seed from another source. Despite their mysterious origins, what is without a doubt is this Chapter's stalwart dedication to the defence of the Emperor of Mankind's realm from enemies both within and without.
Sons Sanguine		The Sons Sanguine are a Codex-compliant Successor Chapter of the Angels Sanguine created during the ill-fated 21^st 'Cursed' Founding. As inheritors of the lineage of the angelic Primarch Sanguinius, the Sons Sanguine have also inherited the twin genetic flaws which linger over their Chapter like a shadow. Though they possess a enviable history of heroism and valour, rumours and unease surround them. Like their genetic forbears, the Angels Sanguine, the Sons Sanguine also shield their faces from those they fight alongside. They also possess a higher number of Librarians than normal.
Soul Destroyers		Amongst the mighty warriors of the Adeptus Astartes exists a chapter that is as much disavowed as it is reviled, for the presence of the Soul Destroyers has been mostly repudiated throughout the annals of Imperial history. Whilst their origin is heavily obscured by secrecy, their existence and outstanding achievements in battle have been confirmed beyond doubt – a fact that High Lords of Terra are at pains to admit. Though the existence of Adeptus Astartes warriors with a psychic blank quality is somewhat known to have occurred within the Imperium, albeit particularly rare cases such as the Grey Knights ferrymen and few other incidents of note, an entire chapter of marines with a reputation of combining the destructive capacity of The Emperor’s greatest creation and the null effect of the Silent Sisterhood remains abhorrent and a source of disgust to anyone able to comprehend the very nature of these monstrosities. (Note: This Chapter falls under the Alternate Universe category.)
Soul Flayers		The Soul Flayers Chapter is a loyalist Successor Chapter created from the heroic lineage of the ancient Blood Angels - founded during the ill-fated 21^st 'Cursed' Founding. Like many Chapters born from the largest Founding of Space Marine Chapters since the Second Founding, the Soul Flayers are plauged with identified deficiencies in their gene-seed. Like their forebears, the Chapter is heavily fundamental in their beliefs of their Primarch, however, the Chapter views the "Flaw of Sanguinius" as a gift from the Emperor himself and sees it as a way to enter into the Imperium's Pantheon as an ordained saint. This has made the Chapter renowned for shock troop tactics, with their reliance of brute force and terror tactics by the hands of their Black Enraged Brethren.
Sovereigns of the Tide		The Sovereigns of the Tide are a semi-Codex compliant chapter from the ill-fated 21^st Founding, the so-called 'Cursed Founding'. They have taken up residence on the ocean world of Laeran that was once home to the ancient Laer xenos species before they were annihilated by the Daemon Primarch Fulgrim and the Emperor's Children Traitor Legion. Due to their reputation of being from the Cursed Founding, the Sovereigns have worked hard to improve their standing with as many other loyalist chapters as they can.
Space Naga		The Space Naga are a loyalist Codex-compliant Successor Chapter created from the proud lineage of the vaunted Ultramarines during the 23^rd Founding, known as the 'Sentinel Founding'. They were created under the dispensation of the High Lords of Terra as a Successor Chapter of the well-organized and highly venerated Scions of Guilliman in order to fulfill the additional defence of the Eastern Fringe against both the Forces of Chaos from the Warp anomaly known as the Maelstorm, the emergent Tau Empire, the tendrils of encroaching Hive Fleets, and marauding Ork WAAAGH! fleets. Under commendation from the Ultramarines' Chapter Master Marneus Augustus Calgar, the Space Naga was given control of the system known as the Indravari System, a system consisting of three planets. The Chapter has become widely known for their formidable psychic defence veil, known as the 'Gautam Veil', that protects the Indravari System from invading xenos or Chaos alike. The Space Naga are also known for their extensive use of psyker-infused melee weaponry which is capable of absorbing souls of daemonic entities, as well as possessing a large quantity of grav weaponry - from the simple grav pistol to the long lost Horus Heresy technology of the mobile platform, Rapier grav cannon.
Spartans of Velox		The Spartans of Velox are a Loyalist Successor Chapter of the ancient and heroic Blood Angels. When they were founded has been lost to time and space, although the earliest reports of activity from the Spartans comes around the 35^th Millennium. The Spartans of Velox are officially reported to be one chapter to the Adeptus Astartes; however, this is a white lie. The Spartans are in actuality a chapter reinforced by the survivors of an older 4^th Founding chapter, the Praetorians of Apollo, another Blood Angels successor who were assumed to be completely annihilated when their original home planet was wiped out by a massive Ork WAAAGH! sometime in M38. The Spartans found the shattered remains of their chapter and took them in under their own banner. Many of the original Praetorians have since died, but the Spartans still maintain the influx of marines from the absorption. As of the 42^nd Millennium, the Spartans of Velox have been spotted in the Apollo System on a campaign to take back the planet of Apollo Prime, the original homeworld of the Praetorians.
Spartiate Marines		The Spartiate Marines are an Ultramarines Successor Chapter created during the 4^th Founding sometime during the late fifth century or early sixth century of M32. They act as a designated offensive force, and paired with those defensive experts the Gatekeepers, are a part of the Hell Warders Chapters - a quintumvirate of five Space Marine Chapters - tasked to defend the Imperium against Chaos incursions from the dual warp rifts known as the 'Hellgates' of Sector Occident Prime, located in the Segmentum Solar uncomfortably close to Holy Terra.
Spectral Wolves		The Spectral Wolves are non-Codex adherent Chapter that was created from the lineage of the sons of Russ Unlike other Chapters, the Spectral Wolves do not possess the usual number of 1,000 battle-brothers, instead numbering around 700. Despite their smaller size, the Chapter's ferocity and stubbornness in the face of overwhelming odds, more than makes up for what they lack in numbers. The Chapter, referred to as the Shadow Company by their Chapter Master, Wolf Commander Tyr Hjalmar, are known for one of the earliest discoveries of the Tyranids beyond the borders of the Eastern Fringe, and were one of the first Chapters to warn the Imperium about the coming of an extra-galactic composite species of hideous xenos, that was in actually, a space-faring ecosystem comprised of innumerable different bioforms comprised of innumerable variations on the same genetic theme - the Tyranids. This Chapter is known for possessing an inordinate amount of frost weapons compared to most other Adeptus Astartes Chapters.
Spider Lords		The Spider Lords are a formerly Loyalist Chapter of the Adeptus Astartes created during the ill-fated 21^st Founding, the so-called 'Cursed Founding', which was notable for a number of Chapters falling into uncontrollable and often spontaneous mutations, aberrant behavior or a susceptibility to falling to the Ruinous Powers. It is believed by Imperial scholars that the Spider Lords genetic lineage hails from the Masters of the Night Chapter, however, it is unknow from which First Founding Chapter their progenitors hail from themselves. The Spider Lords would later be declared Excommunicate Traitoris for severe mutation aberrations and barbaric practices they carried out. (Excommunicate Traitoris)
Squallguard		The Squallguard are a loyalist Space Marine Chapter created during the Ultima Founding, from the gene-seed of the White Scars. They are perhaps unique as a chapter in that every full battle-brother is clad in Mk X Gravis Armor, and possess a large amount of Redemptor pattern Dreadnought suits. Thusly, the Squallguard specialize in heavy support, grinding attritional warfare, and mechanized assault. This was not always so, and the chapter's identity as it is now was forged in the fires of harsh conflict and necessity. The astartes of the Squallguard are also avid historians, each and every one possessed of a tight grasp on the intricacies of literature, historical precedent, and tactical theory. As an extension of this emphasis on learning and applied knowledge, the Squallguard are masterful diplomats and orators.
Star Angels		The Star Angels are a Loyalist chapter of Space Marines that are suspected to have been created in the 23^rd 'Sentinel' Founding, of an unknown lineage. Their fortress-monastery 'The Hallowed Star' is located on the arid desert Feral World of Indeius. They are unusual in that a Chaplain may rise to the rank of Chapter Master (referred to as High Chaplains), most notably being Morterus, who led the chapter in their ill-fated crusade across the Caligari Sector.
Star Crusaders		The Star Crusaders are a relative young Loyalist Space Marine Chapter founded in M39 during the 24^th Founding as a fleet-based Chapter to conduct space warfare, low/zero-g combat as well as a rapid response against enemy fleets who were able to penetrate deep into the Imperium. The Chapter's most notable battles were against the Tyranid Hive Fleet Leviathan which attacked the galaxy in two directions from below. Such an attack was the example why the Chapter had been formed and currently is engaged with the remaining part of this hive fleet.
Star Golems		The Star Golems are a Loyalist Space Marine Chapter of the Adeptus Astartes founded in M37 during the 23^rd 'Sentinel' Founding and are descendant of the ancient and proud Salamanders. Recognizing their goal to recover Vulkan's relics, some members of the chapter would raise the question as to why they do not seek to recover all forms of technology that the Imperium values so dearly and not primarily the relics of their Primarch. This question being raised resulted in some members of the Salamanders to attempt just that in their missions. These inquisitive astartes would find that they had been so focused on the Artefacts of Vulkan that they had missed countless opportunities to bring back technology that would have aided the Imperium in a measurable capacity.
Star Heralds		The Star Heralds is a Loyalist Space Marine Chapter created from unknown lineage during the 4^th Founding following the near-disastrous War of the Beast which saw the largest Ork WAAAGH! nearly bring the Imperium to its knees. This conflict incurred terrible costs upon the Space Marine Chapters of the Adeptus Astartes and the other military forces of the Imperium of Man. Only through extreme sacrifice and valour was this massive Ork WAAAGH! defeated. Since their inception, the Star Heralds have continued to steadfastly stand eternal vigil over the realms of the Emperor to ensure it remains defended against threats both from without and within. They have continuously crusaded across the width and breadth of the Imperium to ensure that Imperial worlds remain free from the tyranny of the apostate, the heretic and the xenos.
Star Knights		The Star Knights are a 4^th Founding Chapter, descended from the Ultramarines. Well known for being masters of tracking and ambushes, the Star Knights were originally a Codex-compliant Chapter until the Age of Apostasy, when their original homeworld, Artemis, was destroyed by both Chaos incursions and Imperial forces loyal to Goge Vandire, which left the chapter very undermanned to the point of extinction. After the tyrant’s death and the coming of Sebastian Thor, the chapter was cleared of all charges and made another world, the largely populated planet of Garo, their new home. Now the Star Knights have been hailed as some of the greatest hunters and trappers - Space Marines able to hunt down and perfectly counter the foes of man.
Star Reapers		The Star Reapers are a foreboding Space Marine Chapter founded at an unknown date and are suspected successors of the venerable Raven Guard. They are a highly controversial and isolationist chapter, with a history of ruthless brutality. These Astartes are experts in lightning-fast manoeuvres planned with a detailed complexity unseen in most Space Marine doctrine. Cloaked in a shroud of deliberate mystery and concealment likely created by agents of the Star Reapers themselves, the Chapter hides from the prying eyes of institutes such as the Inquisition and even other Chapters considered allies. Indeed, the only beings that know every secret of the Chapter are its master and the Emperor Himself.
Starborn Giants		Raised during the recent 24^th Founding, the Starborn Giants is a fleet-based Chapter infamous for zealously enforcing conformity throughout mankind's domains. The Chapter's belief in the Imperial Creed and the divinity of the Emperor sets it apart from other Successor Chapters of the Salamanders. The Starborn Giants' strange interpretation of the Promethean Cult causes many Salamanders successors to avoid or disown the younger Chapter. The Starborn Giants, therefore, have few allies within the Adeptus Astartes, and their austere adherence to dogma combined with their grave genetic flaws repulses much of the wider Imperium, driving the Chapter deeper into the arms of the Ordo Hereticus.
Starforgers		The Starforgers is a loyalist, fleet-based Chapter created from the lineage of the Raven Guard during the 23^rd 'Sentinel' Founding. This reclusive Chapter resides in the far fringes of the Segmentum Pacificus. This little-known and enigmatic Chapter is far removed from traditional Imperial designs, instead following their own customs gained over such lengths of time alone in the void. This led the Starforgers to operate independently throughout the region. The Chapter's history is steeped with tragedy and trials with the Chapter once thought to have been destroyed entirely, being declared extinct in the Imperial record. The Starforgers leave Imperial reports with a scarce amount of information on the Chapter, with almost all attempts of contact seemingly unsuccessful. Despite this, sightings of the Chapter continue among various war zones across the segmentum.
Steel Crusaders		The Steel Crusaders are an 8^th Founding Successor Chapter of the stoic Iron Hands. Like their progenitors, the Steel Crusaders heavily augment themselves with numerous bionics. The Steel Crusaders are known for using heavy weapons and mechanized warfare to swiftly and efficiently sweep away enemy forces. Operating from the Star-Fortress Teigfestung, this fleet-based Chapter patrols isolated areas of the Imperium. With their mighty war machines the Steel Crusaders bring utter ruin upon the enemies of Mankind.
Steel Harbingers		The Steel Harbingers are an ancient and venerable Space Marine Chapter created during the 3^rd Founding at the dawning of M32. This Founding took place following the tragic era of the Age of Darkness during the Horus Heresy, the subsequent Great Scouring and the sundering of the Legiones Astartes into separate Chapters. It is unknown with any certainty from whom this Chapter is descended from, but many of their cultural beliefs and propensity for utilizing bionics mirrors that of the the stoic and unforgiving Iron Hands, though these Sons of the Gorgon refuse to acknowledge the Steel Harbingers as one of their own.
Steel Hart		The Steel Hart are a strictly Codex-compliant Astartes Chapter, officially of Ultramarines descent. However, in reality, they are actually descended from Iron Warriors' stock. Originating from the 3^rd Founding, the Steel Hart are deeply loyal to the God-Emperor of Mankind and the eradication of His enemies, and have amassed an exemplary record in this regard. However, the Steel Hart have at times shown a disturbing and callous disregard for their own lives as long as their mission objectives are achieved. This cavalier attitude has often carried over to their auxiliaries or allies, each burdening heavy casualties alongside the Astartes Chapter.
Steel Kindred		The Steel Kindred are a semi-Codex Compliant Chapter created in the Ultima Founding descended from the stoic Iron Hands. They are bound by their pragmatic logic that sees them carry out well calculated plans with efficient zeal and augment their weapons, armour and bodies with cybernetic augmentations. Furthermore they are known for using massed firepower to utterly destroy all who stands before them, even if they are allies who are unintentionally in the Steel Kindred's way.
Steel Scions		The Steel Scions are a semi-Codex Compliant Successor Chapter of Adeptus Astartes created from the lineage of the stoic and unforgiving Iron Hands. This Chapter is located in the southern fringe of the Imperium of Man and was created in order to specifically patrol that stretch of space and target Tyranid threats. These Sons of Gorgon are a fleet-based Chapter whose mobile Chapter fleet patrols the fringes of the Imperium, ever-vigilant for encroaching threats from the Great Devourer, and ready to meet any threat at a moment's notice.
Steel Sentinels		The Steel Sentinels are a Successor Chapter of the heroic Ultramarines, created during the recent Ultima Founding after the Unnumbered Sons were broken up into separate chapters. Preferring a full frontal assault with little finesse, the Steel Sentinels march into battle in full force, reminiscent of the pre-heresy Death Guard before the outbreak of the Horus Heresy.
Steel Tempests		The Steel Tempests are a 25^th 'Bastion' Founding successor chapter hailing from the lineage of the Iron Hands. Well known for their discipline and professionalism, as well as their characteristic scathing wit and remarkably casual Chapter culture (most unusual for a Chapter descended from Ferrus Manus), the Steel Tempests have been led by Chapter Master Rainald for almost two centuries
Steel Tigers		The Steel Tigers are a Successor Chapter of the Adeptus Astartes, with their lineage drawn from the White Scars and founded in the year 862.M37 as part of the 23^rd 'Sentinel' Founding. The Chapter finds its home in the Kassari System, with its homeworld being the Hive World of Kassari Primus although its Fortress-Monastery is on the moon of Sannoris. Due to the varied ecosystems found across the Kassari System, the Steel Tigers are experts at fighting and tracking in any terrain and prefer hit-and-run tactics to whittle down an enemy before breaking them with a charge.
Steelscale Wyverns		The Steelscale Wyverns are a unique and enigmatic Successor Chapter of the stoic and unforgiving Iron Hands Chapter. Their origins and practices deviate significantly from their progenitors, focusing on the fusion of bio-mechanical augmentation and the distinctive incorporation of metallic scales in between the layers of their skin. These practices have shaped the chapter's personal identity and combat doctrine.
Stellar Eagles		The Stellar Eagles is a Loyalist Successor Chapter of the Raven Guard created during the recent Ultima Founding. They hail from the world of Kerath in Ultima Segmentum. Kerath was home to the Void Raptors Chapter, of which the Stellar Eagles were intended as primaris reinforcements for the depleted Chapter. However, unknown to outsiders and for mysterious reasons, the Chapter had become renegades. With righteous anger, the Primaris Marines attacked their Firstborn brethren, and when all was said and done, the entire officer cadre and most of the Chapter specialists were slain, including two-thirds of the Firstborn renegade marines. In the aftermath of the civil war, the commanding Primaris Captain reorganised the chapter into the newly renamed 'Stellar Eagles'. They went on to reclaim the system and their fallen Battle-Brothers' honor, with the remaining renegades being purged and all records as the circumstances surrounding this conflict were also purged from all official records.
Stewards of the Crucible		The Stewards of the Crucible are a Loyalist Space Marine Chapter of unknown genetic lineage created during the 4^th Founding in 546.M32 following the catastrophic War of the Beast, which saw the near destruction of the Imperium of Mankind and the full destruction of several Space Marine Chapters. As one of the new hundreds of Chapters created in the destructive wake of the massive Orks WAAAGH!, the Stewards of the Crucible were charged with crusading across Segmentum Obscurus to hunt down remnants of the Greenskin hordes. In this mission, the Stewards would act as the quelling of numerous would-be Ork WAAAGHS!, putting down innumerable upstart Warlords seeking to take over the species-wide void left after the death of The Beast. Most intriguing about the chapter, recently at least, is their new obsession with the hunt and eradication of the World Eaters and forces of Khorne. This can be tied into the disastrous "Vengeance Unbridled" campaign of 321.M39 that cost the Chapter half of their forces and abandonment of their fleeting ways.
Storm Angels		The Storm Angels are a 26^th Founding Chapter hailing from the prestigious genome of Primarch Sanguinius, by way of their progenitors the Wings of Salvaxes. Like their predecessors, they stand aloof from the rest of the scions of Sanguinius and even from the Chapter from which they were spawned. Ritually cannibalistic and especially savages in their wars, this Chapter has recently underwent the Rubicon Primaris in full force, willing to risk annihilation to better fight against the enemies of the Imperium without sacrificing the lineage they are highly proud of.
Storm Dragons		The Storm Dragons are a Loyalist Space Marine Chapter created during the ill-fated 21^st Founding, the so-called "Cursed Founding", from unknown gene-seed. Hailing from the storm-wracked world of Sturmwelt, located in the middle of the Segmentum Obscurus, their world is consumed by continuous electrical storms. This chapter is noted for it's prowess in swordmanship and melee combat. They have fought valiantly against Chaos and xenos alike as they seek the truth behind their origins even to this day. The Chapter is currently led by Tempest Lord Raihan, who leads the chapter in memory of his fallen twin Raikor. Always striving to do right by his dead brother, his Chapter, and the Imperium as a whole, Raihan is considered by his battle-brothers to be the most noble of the chapter.
Storm Fists		The Storm Fists are a loyalist successor chapter of the Imperial Fists created during the 15^th Founding in late M35. Like their progenitors, the Storm Fists are extremely disciplined and unyielding, both when attacking or defending, often resulting in casualties beyond what the Codex Astartes would consider acceptable losses. The chapter was devastated fighting in the Dark Imperium is currently reconstituting losses from Primaris Marines that share the blood of Rogal Dorn.
Storm Griffons		The Storm Griffons are a Loyalist Chapter of the Adeptus Astartes and the supposed successor of the ever-venerable Dark Angels. There is no record of which Founding created these sons of the Lion, but the consensus amongst the Inquisition is that the Chapter was founded in mid M35, at the height of the Nova Terra Interregnum. Thrown into the fires of combat from the very beginning of their sigil to the throne, the Storm Griffons have faced against a myriad of mankind's foes. From the dark and claustrophobic walkways of floating space hulks to the wide-open expanses of tundra and death world plains, the chapter has been hardened and tempered in the fires of conflict. The chapter is fleet-based after the events that led to the annihilation of their homeworld Nyota IV in late M41.
Storm Guards		The Storm Guards are a 3^rd Founding Successor Chapter of the noble and mighty Salamanders. Founded by Volovydae Ortys, a survivor of the Horus Heresy, he became changed by what he experienced and grew to resent what the Imperium was becoming in the aftermath of the civil war, believing it was straying away from what both the Emperor and Primarch Vulkan envisioned. Thus when the time came for new Chapters to be formed, Volovydae took the mantle of Chapter Master of the newly made Storm Guards, and claimed the Kabeiroi Sector as their home, with the capital planet Velum as their base of operations. Strong believers of Vulkan's Promethean Creed, in addition to their strong diversity from the Codex Astartes, they have a tense relationship with the Ecclesiarchy and the Inquisition, in addition to many planetary leaders and military commanders who have shown a lack of empathy for civilians, whom they show a zealous determination to protect matched only by their utter hatred towards traitors and xenos.
Storm Heralds		The Storm Heralds are a rare Codex-compliant Successor Chapter created from the lineage of the wild and fierce White Scars during the latter half of M40 during the 25^th 'Bastion' Founding . This Chapter hails from a planet with two suns, the storms heralds a time of great violence as lightning and thunder crash above, while torrential downpours of rain create flash floods. But this violence is followed by a time of peace, as the light of the suns is obscured by dark storm clouds, allowing the inhabitants a time of respite from the hot glaring suns. The chapter takes its namesake from this phenomenon.
Storm Knights		The Storm Knights are a Loyalist Space Marine Chapter created during the 19^th Founding in mid-M36 from unknown genetic lineage, however, Imperial savants believe they were created from the lineage of the mysterious and enigmatic Dark Angels. The Chapter continuously served the Emperor's will for nearly a millennium until they faced near extinction on the world of Sengor II to an unknown race of xenos. In the current millennium the Storm Knights have faced heavy combat in the Carrobract System, crusading against a never ending horde of cultists, Traitor Astartes and daemons.
Storm Marchers		The Storm Marchers are a Codex-compliant Loyalist Space Marine Chapter comprised entirely of newly revealed Primaris Space Marines, created during the recent Ultima Founding of 999.M41. Their lineage descends from the gene-seed of the stoic Imperial Fists. The Storm Marcher chapter specifically trains and specialises in hazardous environment warfare on planets with severe geological conditions. Although the chapter is Codex-compliant, there are a few minor alterations that the Storm Marchers have done to their equipment to better suit their style of warfare.
Storm Riders		The Storm Riders are a Loyalist Fourth Founding and rare Successor Chapter of the highly venerated White Scars. Created during the latter years of M32, almost nothing is known about this Chapter in official Imperial records other than that they share their forefather's battle-lust and aggressive style of lighting warfare. The Storm Riders are notable for their duality of character - being a highly aggressive and bellicose Chapter which are uncompromisingly brutal to their foes almost to the point of savagery - but are also known for their nobility of character. This Chapter is stoic and fiercely loyal in their duties of protecting the weak and the innocent, embodying all that is best in the sons of the Great Khan.
Storm Sentinels		The Storm Sentinels are a proud and noble Loyalist Successor Chapter created from the stoic and venerable gene-seed of the great Rogal Dorn during the 25^th Founding. As proud inheritors of Dorn, like their genetic forebears, the Storm Sentinels are also specialists in siege warfare as well as ranged combat. Making their demesne within the borders of the Segmentum Tempestus, the Storm Sentinels often combat the Ork menace that often assails this volatile region, and often conduct xenocidal campaigns to halt the greenskin menace.
Storm Sons		The Storm Sons are a rare Successor Chapter of the venerable, highly mobile and feared White Scars Chapter. Created sometime during the 24^th Founding in M39, the Storm Sons, like their forebears, enact swift and brutal justice against those who transgress against the Emperor and his Imperium of Man. Born in the turmoil of apostasy, for over two thousand years the mystic warriors of the Storm Sons have exacted swift and relentless vengeance against the enemies of the Emperor over the entire breadth of the known galaxy.
Storm Wraiths		The Storm Wraiths are a Chapter, that until just recently, was of both an Unknown Founding and an unknown lineage amongst the Loyalist Chapters. With a history now nearly as old as the Imperium itself, they can now verifiably trace their heritage all the way back to the ancient 2^nd Founding that occurred at the end of the Great Scouring in 021.M31. Hailing from the Amerikon Sector of the Segmentum Tempestus, the Storm Wraiths have been known by many as an influential buffer for the many systems of the inner Imperium against the various foes of Mankind that constantly invade from the Galactic South. Known for their strong forward assaults from both land and sky, protected by ancient and rare wargear and support by vehicles of ancient provenance, their famed-usage of Heresy-era armour and armaments has led to a legacy of being a "ghost chapter" - a remnant of a bygone era.
Storm Zealots		The Storm Zealots are Space Marine Chapter created during the 23^rd ('Sentinel') Founding. They were created under commendation of the High Lords of Terra as a Successor Chapter of the highly vaunted Imperial Fists as an additional defence to the Herzavar Sector against the emerging Tau Empire, the Forces of Chaos and the encroaching Hive Fleets. Unlike most Space Marines that follow the Imperial Cult, the Storm Zealots and their people, the Jerasians as a whole, are also defined by their adherence to a variation of the Imperial Cult called the Jerasian Ark. Before the coming of Primaris Astartes, the chapter is known to posses Centurion Devastator Warsuit more than any other chapters, yet after the famous Zerubavel Reform, the chapter is known for its bolter mastery, possessing more Gravis Armor Units, and its possession of innovative device named Shieldkiller technology that could disable the enemy shield generator with superb precision. The chapter is also possess a strong xenophobic tendency towards the Tau Empire.
Stormborn		Born during the 23^rd 'Sentinel' Founding, the Stormborn are a Chapter famous (or infamous) for the importance they place upon their honour and their almost suicidal refusal to retreat or compromise. Coming from the world of Tennin; a world of islands and warring feudal lords the Stormborn are a rigid and unbending force. As a Chapter they have had a tumultuous history, but one filled with honourable actions and fearsomely impressive deeds.
Stormbreakers		The Stormbreakers are a recently created Space Marine Chapter from the 26^th Founding in 738.M41 from the genetic lineage of the stoic and taciturn heritage of Rogal Dorn, Primarch of the venerable Imperial Fists. Following the destruction of their former home world in 800.M41 by an invading Ork WAAAGH!, they were forced to enact Exterminatus. Reduced to under 300 battle-brothers, the future of the Stormbreakers looked bleaked. However, the Chapter received relief in the form of a Torchbearer fleet in 999.M41. They bore a profound gift from the hand of the Emperor Himself - the next stage of transhuman warriors - the Primaris Space Marines. Utilising this new technology, the Chapter was able to quickly replace their extensive losses within a few short years their Chapter was back to full strength. Now they are comprised mostly of these newly advanced warriors.
Stygian Krakens		The Stygian Krakens are a mysterious and foreboding Loyalist Chapter of the Adeptus Astartes. The origins of this aloof Chapter are as shadowy and mysterious as their dark blue battle-plate that reflects no light - just like the fathomless depths of the oceans of their former aquatic death world of Kharybdos. Imperial scholars have been unable to determine exactly when this Chapter was created, as extant records are often fractious or contradictory. A grim and morose Chapter, the Stygian Krakens prowl the starless void of the Halo Stars, emerging back into the known galaxy seemingly at random - their aid unheralded and unasked for - aiding various void-faring colonies and vessels as well as any Imperial worlds and forces they come upon. They hunt down and slaughter those that would dare encroach upon the Emperor's domain - be they xenos, heretic or daemonic.
Sun Guard		The Sun Guard are a Loyalist Codex-compliant Space Marine Chapter of unknown founding, though commonly regarded as Successors of the Ultramarines. Having served the Imperium since M32, they are counted among the most dedicated and loyal of the Adeptus Astartes, earning the respect of their comrades-in-arms and many Imperial institutions through countless wars and battles. The Sun Guard are brutal, ruthless and unwavering, yet also honorable and capable of a modicum of mercy. It is said of them that there is no oath which they do not uphold, and their oath to the Emperor has made them a terror to the foes of mankind. They hold great disdain for treachery even towards temporary allies, believing that such things are the ways of heretics. They regard no treachery with as much hatred as the Horus Heresy, and this hatred manifests itself as great wrath against the Black Legion.
Sun Serpents		The Sun Serpents are a Chapter of the 21^st 'Cursed' Founding. A strange force, they are said to be successors of the Salamanders, despite showing none of the genetic markers of the sons of Vulkan. An honorable and loyal Chapter, despite then numouers laudible victories and enviable battle record the Chapter has attained over several millennia, the Children of Ce Acatl are often treated with distrust and fear.
Sun Warriors		The Sun Warriors are a Loyalist non-Codex compliant Space Marine chapter created during the 12^th Founding. They are known for their intense worship of God-Emperor, whom they call the Haring-Maykapal. Formerly a fleet-based chapter, they were awarded the planet of Apolake for their involvement in the campaign known as the Deathgold Trails. The chapter brings the might of the God-Emperor’s Light to His foes in glorius fashion with the use of flamers, melta-guns, orbital bombardments, and drop pod assaults. During the closing days of the 41st millennium, their home system was lost to Deathskull Mek-Boss Mekmonga and his WAAAGH!. Their defeat forced the chapter to leave the system with anyone and anything they can save, while their strength was greatly reduced to less than a third. Currently, they are rebuilding in preparation for the reclamation of their homeworld and surrounding planets.
Swarm Stalkers		The Swarm Stalkers are a Loyalist semi-Codex-compliant Space Marine Chapter of the Ultima Founding. Their ranks are populated exclusively by Primaris Space Marines. The chapter was created from the gene-seed of the Novamarines with the purpose of protecting the Imperium of Man from the Great Devourer.
Sworn of Guilliman		The Sworn of Guilliman are a formerly Loyalist Space Marine Chapter and sole known Successor Chapter of the Metamarines, created during the 26^th Founding. Following the near-annihilation of the Chapter, during the events the now-rebellious Astartes call 'The Betrayal', the renamed Chaos warband, known as The Betrayed, are slowly drifting towards pure Chaotic corruption - even if its members are still far from true believers - instead favouring the use of minor daemons as auxiliaries in their raids. (Excommunicate Traitoris)
Sword Wardens	Pict-File Unavailable	The Sword Wardens are a loyal Successor Chapter created from the lineage of the proud and heroic Ultramarines during the 6^th Founding. They have proven themselves to be loyal and capable combatants with a sense of diplomacy since their inception. Which disappeared for several years during the opening of the Cicatrix Maledictum. A decade later, their fleet emerged from the warp. To everyone's astonishment, they had no well-known officer in their ranks. All senior officers were unknown to their allies. The Sword Wardens explained this fact through very costly fights during their odyssey. But connoisseurs of the Sword Wardens quickly noticed many oddities with them. So they didn't know many of their customs or only partially. Their behavior towards their allies also changed. At the same time, they isolated themselves from the rest of the galaxy. Only the Emperor knows what's going on with them or what happened during their odyssey.
Swordmasters		The Swordmasters are a heroic Successor Chapter of the noble and heroic Blood Angels created during the 9^th Founding. They are famous for their championship in the art of sword fighting and the deployment of power swords.
Swords of Guilliman		The Swords of Guilliman are an ancient Second Founding Successor Chapter of the vaunted and much lauded Ultramarines. They were initially created from the surviving members of the XIII Legioon's 19^th Company that fought in the devastating Underworld War beneath the surface of Calth during the Horus Heresy, led by their famour Praetor Steloc Aethon. It was from these heroic elements that Aethon would go on to form the Swords of Guilliman Chapter, following the dissolution of the Legiones Astartes. Since those dark days of despair and shattered hopes, the Swords of Guilliman have stood against the void, never withdrawing or retreating from a threat, no matter the size or the cost to their own. Striking from their homeworld of Nova Macragge from their powerful Chapter fleet, the Swords have continued to protect the northewestern region of the Imperium, taking any mission given, as long as there is glory, vengeance or innoncent lives at stake.

Teeth of the Storm		The chapter of the Adeptus Astartes known as the Teeth of the Storm is a 4^th Founding Chapter created in the middle centuries of M32, following the near-disastrous War of the Beast. The Teeth of the Storm was one of several newly created Chapters created to help bring order to an Imperium rife with civil strife and insurrection, and to help restore Imperial law. Following their inception, they were charged with standing sentinel against xenos and Chaos threats in the Maelstrom Zone, the region of Imperial space surrounding the notorious Maelstrom warp rift.
Tempest Guard		The Tempest Guard are a loyalist, Codex Astartes-Compliant space marine chapter of unknown origin and unknown founding. The chapter is known for its fiercely loyal attitude and has also been known to participate in Imperial Campaigns on a whim. Although their founding and lineage are a mystery, the chapter has cast these aside as little more than distractions from the Emperor's Fight in the Long War. The chapter is also known to have a malfunctioning Catalepsean Node, forcing individual Battle-Brothers to stay awake for days on end. This flaw has become known as the Eternal Vigil. (Note: This Chapter falls under the Expanded Universe category.)
Tempest Knights		The Tempest Knights are a Codex Astartes-compliant Loyalist Chapter of Space Marines who are a 4^th Founding Successor Chapter of the Imperial Fists. The newly created Chapters of this Founding were created to help restore order to an Imperium rife with civil upheaval and insurrection. Since their inception, the Tempest Knights have continued to maintain order and bring swift justice to those who would dare sow discord or preach rebellion.
Tempest Wolves		The Tempest Wolves are a recently-created Primaris Space Marine Successor Chapter made from the lineage of the feral and unforgiving Space Wolves. This Chapter was formed due to the need for more guns on the front for the Indomitus Crusade and the spread of the massive warp rift, known as the Great Rift, across the length of the galaxy. Created with a new generation of the Space Wolves' geen-seed to try and lessen the effects of the 'Curse of Wulfen', they were sent to the world of Tyrheim, a relatively new planet discovered by the Imperium. They immediately assumed command of the planet and began to turn it into a bastion against the enemies of the Imperium and deployed hundreds of their warriors to fight on the front, especially Armageddon.
Tempestors		The Tempestors are a Loyalist Space Marine Chapter created during 10^th Founding from uncertain lineage. This Chapter is one of the few Space Marine Chapters that willingly ally themselves with the Adeptus Administratum because of the old rivalry between warrior and bureaucrat. While others avoid the bureaucratic nightmare, the Tempestors are willing to cooperate and have learned to navigate through the jungle of bureaucracy making themself quite the name of tithe collectors. But this is not their sole speciality. The Tempestors are known for their swift strategical movements and mastery of information warfare.
Templars Moline		The Templars Moline are a formerly-extinct Loyalist Successor Chapter created from the zealous and dedicated Black Templars, who themselves hail from the proud lineage of the stoic Primarch Rogal Dorn. Presumably created during the 14^th Founding, sometime between 975-991.M35 as a part of several linked Foundings, the Templars Moline carried on the proud traditions of their Crusading progenitors and took to the stars in a massive warfleet. Later on, they would become a part of the Hell Warders - a quintumvirate of five Space Marine Chapters tasked to defend the Imperium against Chaos incursions from the Hellgates - dual warp storms located in the Segmentum Solar which are uncomfortably close to Holy Terra. Tragically, the Chapter would meet a dire end when the entirety of their Chapter fleet disappeared into the warp rifts during the Castigation Crusade of 742.M41. They were officially declared lost two years later after a careful search by their fellow Warders found no survivors. At the dawning of M42, with the events surrounding the destruction of Cadia and the formation of the galaxy-wide tear in reality, known as the Cicatrix Maledictum, the Templars Moline have once again risen from the ashes of their former demise in the form of a new Ultima Founding Chapter comprised entirely of Primaris Space Marines. With the re-formation of the Templars Moline the Hell Warders have been re-forged anew. However, only time will tell whether or not these new Astartes will live up to the heroic legacy of their forebears.
Templars of Iron		The Templars of Iron are a Successor Chapter of the Iron Hands. These scions of Ferrus Manus are noted for their stern demeanour and ruthless persecution of their foes. This Chapter, along with the Iron Gorgons and the Iron Harbingers, make up a triumvirate of 2^nd Founding Iron Hands' Successors, collectively known as the Frateris Firmitatis ("The Ironclad Brotherhood"). Since their inception, the Templars of Iron have amassed a substantial tally of glorious victories down the millennia. Like their Progenitors, they too, have a hatred of the flesh and share their predilection for replacing parts of their bodies with bionics and cybernetic enhancements. In battle, the Templars are noted for their stoic resolve and stubborn determination to succeed in the face of overwhelming odds, as they fight on without remorse for their foes, or even their own lives.
Templars of Sanguinius		The Templars of Sanguinius are a loyalist Successor Chapter hailing from the proud lineage of the heroic Blood Angels. Officially, this Chapter was created during an unknown founding, however, extant records indicate that the Templars of Sanguinius were actually created during the 23^rd Founding, the so-called 'Sentinel' Founding, which occurred during the latter part of M37 and early M38, to repair the power and reach of the Adeptus Astartes that had suffered considerable losses in the preceding millennia. These staunch and zealous defenders of the Imperium have stood sentinel over the realm of the Emperor of Mankind for millennia, standing as a bulwark against the apostate, xenos and daemonic. However, despite their noble bearing and appearance, like all Chapters of the Blood, they too suffer from the "Twin-Flaws", which adversely affects their battle-brothers.
Temporal Lords		The Temporal Lords is a mysterious Chapter with a long and dark history. Created during an Unknown Founding and of uncertain lineage, the Chapter's annals of the Temporal Lords contain a secret so dangerous that its discovery would spell doom for the Chapter. Whatever they may have done was terrible enough that much of their early history has been completely erased and remains known only to the Temporal Lords themselves, who work tirelessly to keep this knowledge to themselves alone. Despite their melancholic exterior, the Temporal Lords are some of the Emperor's most zealous warriors, desperately seeking redemption for their past sins.
Tenebris Shades		The Tenebris Shades are a fleet-based Loyalist Astartes chapter of an unknown Founding that hails from Dark Angels lineage, the first sign to their secretive nature, as a successor of the Angels of the Blade who supplied their initial command structure and several warships and relics to them. They are masters of covert operations as well as stealth assaults, often their allies never even know that they helped or intervened in any way.
Terra's Hammers		The Terra's Hammers are a Successor Chapter of the stoic Imperial Fists created during the 12^th Founding specializing in heavy shock assault based around amassed assault utilizing advanced adaptations of the Codex Astartes tactics primarily situated around sieges and full-scale apocalyptic assaults. The hammers have been present for many major battles during the Imperium's history from the decades proceeding the Age of Apostasy in early M36 and onward.
Thousand Blades		The Thousand Blades are a loyalist Codex-compliant Successor Chapter created from the proud lineage of the famous White Scars during the 23^rd Founding, known as the 'Sentinel Founding'. They were created as an additional defense in the Herzavar Sector, Eastern Fringe against both the Forces of Chaos from the Warp anomaly known as the Maelstrom, and the Xenos that lurk in the Herzavar Sector be it Tau Empire, Orks, nor Tyranids alike. All members of this Chapter are solely recruited from Wojtyla, a Hive World surrounded by icy swamps and is well known for its Imperial College of Ladowsk. The Chapter is widely known for its expertise and superbly coordinated battle-fleet tactics in the realm of void warfare, fast attack, and multi-vector and harrowing assault. The Thousand Blades are also known for possessing a large quantity of Outrider Squad, Storm Hawk and Storm Talon gunships at their disposals.
Thunder Guardians		The Thunder Guardians are semi-Codex compliant Loyalist Successor Chapter of the stoic Imperial Fists. Created during the 8^th Founding, the Thunder Guardians have garnered a reputation as ever-vigilant, sworn defenders of the Orlrava Sector located on the southern side of the galaxy. Besieged by various xenos races, including Tyranids, Orks, Genestealers, Eldar, the Forces of Chaos and much more, their hope lies in unity with other factions of the Imperium. Their system has been in a besieged state for much of its history, at the moment it is facing its worst yet. Aided by the forces of the Astra Militarum, Sisters of Battle and the Crimson Fists, they may yet stand against the tide.
Thunder Lords		The Thunder Lords are a loyalist Adeptus Astartes Chapter, coming from the 12^th Founding, being successors of the XIII Legion, the venerable and honoured Ultramarines. Although somewhat Codex-divergent, they still abide by many of the Codex Astartes rules and guidelines, including sticking to the 10 Company limit. The Thunder Lords, though once a very isolationist Chapter and only staying in their system and defending it, have recently begun to spread themselves out and help the sub-sector, and even to the Segmentum that they reside in, the Segmentum Pacificus.
Thunder Ogres		The Thunder Ogres are a mighty and proud Successor Chapter that hails from the lineage of the lauded and ancient Salamanders. They were created as a part of the 26^th Founding in 738.M41, the final founding of the Firstborn Chapters of the Adeptus Astartes that occurred during the 41^st Millennium.
Thunder Raptors		The Thunder Raptors are a non-Codex-compliant chapter of the Ultima Founding, composed entirely of Primaris Space Marines. The chapter’s gene-seed is officially listed as being of the Raven Guard and the lineage of Corvus Corax, and this shows in their expertise in all things concerning aerial warfare, including air assaults, orbital insertions, and air combat, be it of the infantry or aircraft variety. The chapter maintains an unusual number of aircraft, from gunships and fighters to heavy dropships. However, the Thunder Raptors completely shun the use of drop pods, instead deploying infantry elements from low orbit or similarly high altitudes equipped with jump packs or grav-chutes. In the wake of the Fourth Tyrannic War, the chapter has struggled to find use on the battlefields of the Tyranid invasion but has seen success in void warfare and acting as anti-pirate forces as lawlessness sets in throughout afflicted sectors.
Tidebenders		The Tidebenders is a loyalist Space Marine Chapter created during the 23^rd Founding, the so-called 'Sentinel Founding', from the lineage of the heroic Blood Angels. They are created for amphibious warfare, a unique niche of combat untouched by many military organizations within the Imperium. This was by necessity given that their homeworld of Kalypse is populated by primordial creatures called the Abyssal Titans that control the currents of the oceans themselves to threaten the native human population. Valuing human life, the Tidebenders undertook this responsibility as stewards/protectors of the Kalypsians and their numerous Island Nations across the Eigth Seas of the planet. Humble and reserved the Tidebenders seek no personal glory nor do they want to be recognized for their actions by the wider Imperium, they simply want to do their part for humanity playing as support for other Chapters and Imperium military organizations to fight back the threats of Chaos, purging the perverted hands of xenos, and quelling rebellions from within.
Tidebreakers		The Tidebreakers are an Ultramarines Successor Chapter from the 12^th Founding that was lost while deployed near the Eye of Terror, but remade during the Ultima Founding with all Primaris Space Marines. They launch their strike forces from the ocean world of E'Vistas in the Segmentum Pacificus, formerly just a minor recruiting world for the chapter but now its homeworld, to wage war on the enemies of mankind but also to restore the glory of their forbearers.
Tigers of Igora		The Tigers of Igora are a Loyalist Space Marine Chapter of the mysterious 21^st Founding, to the so-called 'Cursed Founding', created with unknown gene-lineage. A savage culture has been inherited from the death world tribes of Igora and is fully-ingrained within the ferocious Astartes of this Chapter. Due to their poor relations with the Adeptus Mechanicus, the Tigers of Igora often carry out field modifications to their arms, armour and equipment that would never be sanctioned by the Priests of Mars, sometimes to improve performance and in other times simply to keep them in service for one battle more. If the need proves dire enough, they will even resort to salvaging wargear from Heretic Astartes and utilise it as a part of their own. To add to their savage appearance, the Tigers are known to collect grim trophies and talismans from their slain foes and will take to decorating their battle-plate with macabre displays of severed heads, limbs, skulls and bones of their enemies.
Toxic Claws		The Toxic Claws are a young Iron Hands Successor Chapter created during the 22^nd Founding that specializes in heavy weapon assaults and the use of toxins and chemical weaponry. Scavengers and survivors, put any weapon, any tool to use that they can, and are known for heavily customizing their own equipment as a point of necessity and pride. Brutal and often cruel warriors, they are known for their singular hatred for the Word Bearers Traitor Legion, and have a history of merciless warfare against these hated foes. They can easily be identified by the bright green markings against their black armour, and a distinctive rodent and hyena motif; indicative of their ability to thrive in the most toxic of environments.
Toxic Reapers		The Toxic Reapers are a non-Codex compliant Space Marine Chapter of the ill-fated 21^st Founding, the so-called 'Cursed Founding'. Officially this Chapter was created from uncertain lineage but is suspected to be derived from Raven Guard gene-stock. They are a fleet-based chapter, their de facto fortress-monastery is the fleet known as the Reaper's Hand. This Chapter has garnered a distasteful reputation for their heavy use of stealth tactics and biological and chemical warfare involving poisons and toxins against their enemies.
Trench Walkers	Pict-File Unavailable	The Trench Walkers Space Marine Chapter are a loyalist non-Codex compliant Successor Chapter that was created from the lineage of the proud and secretive Dark Angels. The Chapter was founded during the recent Ultima Founding and comprised entirely of Primaris Space Marines and is a known Successor Chapter of the Dead Bells. These battle-brothers are recognized for their knowledge and use of biological and chemical warfare agents on battlefields across the galaxy.
Tsunami Riders		The historical protectors of Sector Baikal since the days of the Great Scouring, the Tsunami Riders are a nigh legendary Chapter within the sector. Officially founded in early M32 as part of the 3^rd Founding, the Tsunami Riders originated as the White Scars Legion's Brotherhood of the Tsunami. With a long and storied past, the Tsunami Riders are specialists in extreme weather fighting, often relying on their own Stormseers to bring about this weather.
Tyrannosaurs		The Tyrannosaurs are a non-compliant Codex Successor Chapter of the Salamanders. They were founded during the ill-fated 21^st 'Cursed' Founding, and like other Chapters founded at the time, were seemingly cursed at their genesis. In the case of the Tyrannosaurs, they were cursed with gigantism, lower-than-average intelligence, fangs and eyes like that of a primordial, Terran beast, and an insatiable hunger for all things violent. This has caused the chapter to draw in the ire of many other Space Marine Chapters, along with the Adepta Sororitas and the Ordo Hereticus, who see the chapter betraying the Imperium as simply a matter of time. Despite this, the chapter still claims complete loyalty to the Emperor of Mankind and his Imperium, fighting all who oppose his rule, whether it be Xenos, Daemon or whatever else might stand in their way. They plunder, destroy and grow themselves all so that they may better serve their Grandfather.
Twilight Lords		The Twilight Lords are a 5^th Founding Chapter of unknown origins. An aloof and secretive Chapter, the Twilight Lords also serve as the Chamber Militant of the Inquisition's Novus Conclave. Forged by an ancient pact, the Twilight Lords carry out the Conclave's orders with brutal efficiency when called upon to do so by their Inquisition allies.
Twilight Shadows		Created during the mysterious 13^th 'Dark' Founding, the Twilight Shadows are a loyalist Successor Chapter descended from the genetic lineage of Primarch Corvus Corax. Like many other Raven Guard successors, they are masters of stealth and lightning attacks, which sets them at odds with many more brazen chapters such as the Black Templars.

Ultra Invictus		The Ultra Invictus are a lauded and seasoned Successor Chapter of the noble Ultramarines and the Avenging Son, Roboute Guilliman. Created during the venerable 3^rd Founding, the Ultra Invictus have striven to be, and upheld, the ideals of questing crusaders. Having sailed the void across the width and breadth of the Ultima Segmentum, the Chapter's brothers are regarded as laudable heroes, particularly during the 13^th Black Crusade. Being gratefully bolstered by the Ultima Founding and the induction of the Primaris Space Marines, the Ultra Invictus have sent portions of their respectable Chapter fleet to aid in the direst of wars, such as the faltering border worlds at the edge of the galaxy-wide tear known as the Cicatrix Maledictum.
The Unblooded		The Unblooded, or 'Filli Insanginatem' in High Baalite, are a semi-Codex compliant Successor Chapter of the vaunted Blood Angels. As a direct successor of the IX Legion, the Unblooded have a long and proud history. Even though they remain curiously obscure despite their honorable battle record. Their relation used to be strained with their parent chapter, strides have been made in reforging the lost bond between the two scions of Sanguinius in the lamentable aftermath of the Devastation of Baal.
Undertakers		The Undertakers are a loyalist Chapter of Space Marines that arose during the 21^st 'Cursed' Founding, claiming lineage from the Salamanders Primarch Vulkan. Before the formation of their chapter, the Undertaker's home world, the Cemetery World of Creole, spent nearly a millennia as an Ork "Toof Mine", shaping the populace by influencing their culture. In addition, Drukhari experimentation during this period lead to an unusual amount of psykers appearing amongst the normal population. These factors would ultimately mold the chapter’s belief about the nature of death, the human soul, and the warp. This would ultimately draw them to the ideal of safeguarding the souls of humanity to their final rest free from the corruption of the Forces of Chaos.
Umbral Brotherhood		The Umbral Brotherhood is a Loyalist Successor Chapter of the ancient and insular Dark Angels Chapter. Born in the latter half of the 40th Millennium during the 25^th Founding, the so-called 'Bastion' Founding, the Umbral Brotherhood were created from the gene-stock of the ancient Dark Angels Chapter. The Chapter was raised as permanent watchers of the Sanctus Imperia Noctis, a dense cluster of Cardinal Worlds within the core of Segmentum Obscurus acting as one of the many Bastions of Faith influencing the Segmentums populace. The Umbral Brotherhood are famous amongst the ranks of the Ecclesiarchy not only due to their duty of protecting those venerating the Emperor of Mankind but following the edicts of the Lectitio Divinitatus as well, gaining the ire and appraisal from among the ranks of the Adeptus Astartes due to their zealous beliefs.
Umbral Spectres		The Umbral Spectres are a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines during the most recent Ultima Founding from the lineage of the stalwart and heroic Ultramarines. This Chapter fought throughout the Indomitus Crusade as a part of the Unnumbered Sons - the legion of newly revealed Primaris Space Marines created from the lineage of all the original First Founding Loyalist Space Marine Chapters.
Umbral Wraiths		Created during the mysterious 13^th 'Dark' Founding, there is very little extant evidence about this mysterious and highly aloof Chapter. Initially, the Umbral Wraiths were created as a powerful and versatile xenos-hunting Astartes Chapter. Their purpose was to lend to aid various wings of the Imperium, and to a lesser extent, be the sword the Imperium so desperately needed. While Deathwatch and the Ordo Xenos were to patrol the borders of Imperial space from xenos incursion, the Umbral Wraiths were to dive into their territory and act as both scout and vanguard. The Chapter was to be made of Dark Angels and Raven Guard gene-seed. However, the Raven Guard's genetic material was too unstable and too precious for such an experiment, especially with the Death Spectres produced within the same Founding. As a result, the Umbral Wraiths were given; --- ##REDACTED – ORDER OF THE INQUISITION## ---
Uncrowned Princes		The Uncrowned Princes are a recently-founded Successor Chapter of the Dark Angels that was created during the recent Ultima Founding during the dawn of M42 and is comprised entirely of Primaris Space Marines. Styled after the old Dark Angels Legion that existed during the Great Crusade and the Horus Heresy, the Uncrowned Princes, as they have been known, have also inherited the old tenets of the Lion during their creation. Due to this, they are noted to have made many major tactical and organizational deviations from the Codex Astartes, as they use a modified version of the Hexagrammaton, which was how the old Dark Angels Legion was organized. Hailing from the forested death world of Blackhaven, which is virtually identical in both climate and culture to Caliban, the destroyed death world that served as the homeworld of the Dark Angels, their parent chapter, the Uncrowned Princes have been forged into Astartes due to their experience of hunting down the large monsters of their homeworld.
Unholy Crusaders	Pict-File Unavailable	The Unholy Crusaders are a Renegade chapter of Space Marines. They have been forced to reside on the dead planet Xalnone. Currently, their founding is unknown due to the destruction of many lore documents pertaining to the Chapter. Which chapter they are a successor of is also unknown, due to them supposedly falling to Chaos shortly after the Chapter was founded. Renaming themselves the 'Lost Crusaders', these renegades have been permanently separated from the rest of the Imperium, who believe they perished long ago, because of this, the chapter is forced to make use of what little equipment they can get their hands on to steal from other Chapters. Unfortunately, this tactic proves successful enough to keep the chapter afloat. (Traitoris Perdita)
Unrivalled		Created as part of the 21^st 'Cursed' Founding, the Unrivalled (then known by the moniker Gamma-Palatine) were once staunch, if arrogant defenders of the Imperium of Man, in the years since their creation however, their strive for martial perfection has driven them into the embrace of Khorne, much to the fury of the Third Legion. Since their fall, the Unrivalled has taken a cruel, vicious pleasure in mocking their despised progenitors, twisting the indulgence of Slaanesh and the Emperor's Children by turning all towards Khorne's endless hunger for blood and skulls. (Traitoris Perdita)

Velites	Pict-File Unavailable	The Velites are a Loyalist Astartes Chapter founded in the 10th founded. Successors of the White Scars, they specialize in scouting, screening and skirmishing in support of Knight and Titan detatchment, and deploy in full skirmishing companies consisting largely of assault bike dand fast attack detatchments and with scouts integrated into all companies.
Venerus Fathers		The Venerus Fathers are a small understrength Adeptus Astartes Chapter that numbers around 300-400 strong with only 10 Dreadnoughts. The chapter was founded around M40, created during an Unknown Founding, but there is no exact date. The Venerus Fathers used to be strong, numbering the authorised 1,000 battle-brothers, but after many battles and unfortunate events their numbers decreased, and with it, their strength. Despite their misfortunes the Venerus Fathers continue to valiantly take the fight the myriad of foes of the Mankind, determined to decide their fate, on their own terms.
Verum Illuminate		The Verum Illuminate is a Renegade Chapter that recruits as a Loyalist Chapter created during the 8^th Founding. The recruit from the Cadian Sector and planets in close proximity to the Eye of Terror, including their home world of Stygian. They teach the recruits to believe in the divinity of the God-Emperor and are steadfast in their search for the truth by the light of the Emperor's truth. However, this Chapter hides a dark truth - many of their senior officiers, including their Chapter Master, secretly follow the Chaos God Tzeentch. Though they appear to outsiders as a stalwart and trustworthy Chapter, the seeds of corruption have begun to germinate and continues to slowly erode the Chapter's loyalty.
Vigil Raptors		The Vigil Raptors are a Loyalist Chapter of the Adeptus Astartes and successors of the Raven Guard through the direct lineage of members of the Raptors seconded to the Deathwatch. The Chapter has been heavily involved in many of the most recent campaigns of the Fratres in Augmentationem, an alliance of Space Marine Chapters who see themselves as bearing superiority to other Astartes. As a Chapter, the Vigil Raptors have been rendered to less than twenty five percent of their chapter size twice without succumbing to extinction, but thanks to their calculating nature and a number of oddities to their gene-seed they have learned to adapt to these crises so well that they have come to flourish where others Chapters of their kind would simply fade from the histories of Imperial record.
Vindicator Lords		The Vindicator Lords are a noble yet unforgiving Chapter of the Adeptus Astartes. As a chapter that has stood tall since M35, the Founding that occurred during this time however, is unknown, and no date has been found providing that information due to data being lost over the millennia that has passed. They're are also the few chapters that denied Primaris Space Marines, but were forced into accepting them. However, they managed to keep the Primaris numbers below 100, so the Chapter possesses only a small number of Primaris.
Voidwardens	Pict-File Unavailable	The Voidwardens is a Chapter that was created during the Bastion Founding with the sole purpose of Patrolling the Ghoul Stars, a region that's known for numerous Xenos threats including those that aren't cataloged by the Imperium of Man.
Void Basilisks		The Void Basilisks are a secretive Loyalist Space Marine chapter descended from the Raven Guard, created during the 23^rd 'Sentinel' Founding during the late 38th Millennium. This Chapter is mostly trusted by other chapters of the Adeptus Astartes due to their intense religious standing, however, some factions are uneasy due to the secrecy on the Void Basilisks' homeworld Caverna Reguli Primus. The Basilisks are always sure to attack before attacked and will not falter in the face of any sign of even the slightest heresy or betrayal. The extreme and unfaltering belief in the God-Emperor of Mankind leads to the Astartes of this Chapter being ruthless and empowered, if necessary, cutting down anything unessential in their path. Due to these tendencies and their secrets, they have made enemies with both the Dark Angels and Salamanders. The Void Basilisks also dislike and distrust these two First Founding chapters as in their view, they are seen as not entirely loyal to the Emperor.
Void Hawks		The Void Hawks are a Raven Guard Successor Chapter, notable for being one of the few Astartes Praeses chapters left in existence, raised during the 24^th Founding to defend the realms of Mankind in close proximity to the Eye of Terror, they have endured countless campaigns against them from the forces of Chaos. Suffering grievous casualties in their early years due to events directly after leaving Holy Terra, the Void Hawks have only recently returned themslves to full fighting strength after recieving Primaris reinforcments. The Void Hawks are mostly Codex-compliant, but with certain extra specialisms that are unique to their chapter. These include dedicated anti-psyker sniper teams, anti-vehicle veteran kill teams, daemon-slaying veteran units, and deep reconnaissance teams, amongst others. Certain aspects of wargear and deployment also differ significantly from the Codex Astartes stricture – these were typically developed and used whilst beyond reinforcement in the warp.
Void Krakens		The Void Krakens, also know as the Alazathian Host and The Blessed Shoal; are a Loyalist Chapter of the Adeptus Astartes birthed during the 13^th Founding of M35 by Inquisitorial means. Once held as renegades, due to the secrecy upon their creation and risks held with their continued existence they were declared Excommunicate Traitoris and ordered to be purged by the High Lords of Terra. Though through their fierce loyalty to the God-Emperor and his Imperium even when held in persecution and exile, with ripe opportunity to turn from His light; They were granted a chance to prove they undying loyalty via penance and oath of servitude. For a time their true Primarch and origin Legion was unknown to them, known only to those at the very pinnacle of the Adeptus Terra and the Ordo Astartes of the Inquisition, as official records state them to be Sons of the Lion, while such a claim holds many discrepancies and is not represented in the Chapter, along with them having no significant relations with the Dark Angels chapter and it's Successors. Their true origins remained mystified for millennia, that was until the now traitor Kasbiel Cordaras, know as the 'Black Kraken' revealed it to be -REDACTED-.
Void Lions		The Void Lions Chapter-Tribe, also known as "The Great Pride", "Leonicine Inatrii" or the "Leonicines" are a loyalist chapter of Adeptus Astartes created during the 23^rd 'Sentinel' Founding in the latter half of M37 under the name of the Lion Guards Chapter. The Lion Guards homeworld was the jungle-covered Death World of Zulup IX, located deep within the Eastern Fringe. The Lion Guard chapter would lose its homeworld when the Zulup star would unexpectedly supernova, destroying the entire system. It was believed that the chapter was annihilated along with the system and were registered as a Lost Chapter. However, a chapter would emerge from the Eastern Fringe during the 41st Millennium claiming to be the survivors of the Zulup supernova incident. This chapter would be at full strength, bear different heraldry, and have a different name than the original Lion Guards chapter.
Void Paladins		The Void Paladins are a formerly Loyalist Ultramarines Successor Chapter created during the 4^th Founding, that was declared a Renegade Chapter, as of M36. They are mostly a fleet-based crusading Chapter but have several planetary fortress outposts for recruiting and resupply. This Chapter follows the tenants of the Emperor's Imperial Truth and endeavours to spread this philosophy throughout the galaxy, despite their renegade status by the Imperium at large. (Traitoris Perdita)
Void Ravens		The Void Ravens form an ancient and nefarious Crusading Chapter, whose history is plagued by bloodshed and atrocities. Born from the ashes and death of the Horus Heresy and delivered during the 3^rd Founding, they have carved for themselves a reputation of bloodthirsty and sadistic Space Marines, which has led to downfall with their Progenitor, the revered Raven Guard. Operating in the depth of space, isolated from most of the Imperium during long decades, or even centuries, those Space Marines have come several times under scrutiny from the Inquisition for their malevolent behaviour and blatant disregard of human lives and sufferings. However, their dedication to the Emperor was always deemed sufficient to avoid the harshest of punishment that could have awaited them, keeping them among the forces loyal to the Imperium.
Void Reapers		The Void Reapers are a savage and bellicose Space Marine Chapter created during an Unknown Founding and from uncertain origin. Many Imperial savants have come to the conclusion that the Reapers are, in fact, an alleged Successor Chapter of the venerable and mysterious Raven Guard due to their similar tactics and genetic idiosyncrasies displayed by the Astartes of this Chapter, however, this remains inconclusive.
Void Selkies		The Void Selkies ('Innanis Phoce' in High Gothic) are a Successor Chapter from the mighty and proud Space Wolves lineage of the Ultima Founding. They hail from the stony ocean world of Mannan and they are stoic and cold-minded like their planet. Ruthless and stubborn they exercise the cult of swordsmanship and are notorious for the two-handers that allow them to go toe-to-toe with the fiercest of enemies. They also like to plan their action before, making sure to annihilate and humble their enemies.
Void Spears		The Void Spears specialise in boarding actions and void warfare. They are from the 26^th Founding of Imperial Fists' descent. Despite being a relatively young chapter they possess relics and war gear from well before their founding. Their armour appears jet black with four-pointed stars connected by interlocking patterns. The chapter is considered quite insular and taciturn, hence much knowledge about them is unknown as for most of their history they have focused on militarising the sector of Imperial Space they have sworn to protect, training Imperial guard regiments and working in tandem with Navy breachers whose 100 personnel strong adjacent force are referred to as the "lethal company" and whose members are often rotated out, serving as an exercise to provide them with experience against the unknown threats of the galaxy.
Void Templars		The Void Templars are a semi-Codex compliant Loyalist Successor Chapter of Imperial Fists' descent. Astartes of this Chapter are masters of void warfare, boarding actions and siege warfare. They were Founded during the 10^th Founding and are followers of the Imperial Creed, fully believing in the Emperor's divinity. They were heavily depleted from a traitor siege of their homeworld until the resurrected Ultramarines Primarch Roboute Guiliman arrived with his Indomitus Crusade and granted the sorely depleted Void Templars with newly revealed Primaris Space Marines and some additional vessels. Currently, they are participating in the Indomitus Crusade. Although they follow the Codex Astartes, they also possess their own unique ranks and Chapter traditions. They are also known for their willingness to help Astra Militarum Regiments and Imperial Navy fleets against any enemy.
Void Vultures		The Void Vultures, a loyalist semi-Codex Astartes compliant successor chapter raised during the 4^th Founding, their origins tracing back to a lineage closely tied to the Obsidian Hammers, who themselves descend from the Primarch Rogal Dorn. Emerging from the ashes of their predecessors, these successors of the Obsidian Hammers have carved a unique path through the galaxy. Their narrative is one of redemption, honour, and loyalty to the Imperium, a testament to the enduring spirit that binds them together as they continue their relentless vigil in the service of the Emperor.
Void Walkers		The Void Walkers are an Ultima Founding Successor Chapter of the famed Raven Guard, comprised entirely of newly revealed Primaris Space Marines. The Void Walkers Chapter was founded in response to the creation of the Great Rift in 999.M41, serving within the legions of the Unnumbered Sons. They began their first combat action, as a Chapter, in 111.M42 in the Kaladin System to relieve the besieged capital world of Ardialan. There they continue to fight an ongoing action against a Chaos invasion of an Iron Warriors Grand Company under Warsmith Khazor.
Void Wardens		The Void Wardens are a Loyalist Raven Guard Successor Chapter founded during the 10^th Founding in the M35. The chapter was created during the unstable period of Imperial history known as the Nova Terra Interregnum to protect the Ascarian Sector from chaos warbands. The chapter would be nearly destroyed in its first century of existence and its current status is unknown.
Void Wyverns		The Void Wyverns are loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created during the recent Ultima Founding in 999.M41, from the lineage of the great Salamanders. The Void Wyverns, along with several other Primaris Successor Chapters, were created to help protect the Imperial sectors of Segmentum Tempestus and supporting Imperial worlds and the Inquisition as needed. All members of this Chapter are solely recruited from Drukar Prime, a feral world filled with swamps, toxic bogs, and crannog tribes that constantly war among each other. The Chapter is known for its close assault tactics, armoured assault, and close-range combat, possessing a large quantity of assault flamers and melta incinerator wielding Inceptor Squads that is unique amongst many other Primaris Space Marine Chapters.
Voidborne		The Voidborne are a Successor Chapter to the White Scars. Founded during the 19^th Founding in mid-M36, their designated purpose and charge was, and still remains, to crusade on the very borders of the Imperium, deep in the cold of interstellar space where they engage the fleets of heretics, xenos, and mutants alike and bring them to ruin. A fleet-based chapter by design and choice as opposed to circumstance, the Voidborne operate almost exclusively in space and specializes in its many tactical intricacies. Void combat, boarding actions, and rapid assaults are their passion and they lean into it with all the fury and joy of their Primarch.
Vulkan's Drakes		Vulkan's Drakes are a Successor Chapter of the Salamanders Chapter. Created during the ill-fated 21^st 'Cursed' Founding, this Chapter primarily deploys against Chaos threats, ranging from cults to marines. They hail from the world of Egya, a planet located close to the central spine of the Great Rift. It also holds close proximity to Prospero, or what remains rather. Vulkan's Drakes are known for and are proficient in frontal and unbreakable assaults, trying to get into close combat for flamer range and melee combat.

War Angels		The War Angels is an Adeptus Astartes Chapter founded in the Illuviam System, working throughout the Ultima Segmentum as a standing force in order to better defend the Illuviam sub-sector from hostile incursions that may threaten the territory in the foreseeable future. The Chapter is relatively young in the history of the Imperium, being founded in M37 during the 23^rd 'Sentinel' Founding, resulting in relying more on more common types of equipment and wargear. The War Angels' gene-sire is that of Roboute Guilliman, informing the Chapter's demeanor of honour and loyalty as well as showing an affinity for the common citizenry within their realm of influence.
War Lions		The War Lions are a notorious Renegade Space Marine Chapter created during the 19^th Founding, which occurred somewhere between 975-991.M35 as a part of a series of linked foundings. Their exact lineage was unknown, and Imperial scholars had been unable to determine exactly which original Space Marine Legion this formerly loyalist Chapter was descended from. However, it soon became readily apparent that something was inherently wrong with this Chapter from the outset, as its Astartes were notoriously bellicose and savage - merciless in the prosecution of their duties. Many fellow Chapters of the Adeptus Astartes found the insular War Lions wanting in brotherhood - darkly tainted from their very birth. It was eventually discovered why: the chapter was created from the gene-seed of the World Eaters Traitor Legion. After several decades of committing excesses that could no longer be ignored, falsified evidence convinced the High Lords of Terra to decree the Chapter as Renegades and declared them Traitoris Perdita. Following this declaration, the War Lions largely disappeared from the records of the Imperium. Nonetheless, the War Lions refused to acknowledge this decree, and proceeded to continue their bloody-handed ways. (Traitoris Perdita)
War Lords		The War Lords are a Loyalist Successor Chapter created from the lineage of the proud and heroic Ultramarines. These pridful sons of Roboute Guilliman specialise in operations in different kinds of terrains and the massive deployment of Scouts. They have fought since late M32 for the Emperor, their gene-sire and for Humanity. The War Lords are famous for their many scouts, even though the dictates of the Codex Astartes does not permit it, but they ignore this illogical ban.
War Ravens		The War Ravens are a notoriously bellicose and unforgiving Successor Chapter created from the lineage of the Ravenlord, Corvus Corax. This ancient Chapter can trace their lineage to the dawn of M32 during the 3^rd Founding, when they were born from the ashes of betrayal of the Horus Heresy and raised up as a new Chapter of Raven Lord's bloodline. Reputedly, they were created directly from the gene-stock of the Shadow Haunters, a little-known Successor Chapter of the Raven Guard. Since their inception, the War Ravens have writ a legacy of death and destruction in the annals of Imperial history, carving a swathe of blood and ash across the void. Their very name has become synonymous with merciless and bloody-handed retribution, acting as the Emperor's harbingers of vengeance. The War Ravens' role as the embodiment of the Emperor's wrath serves as a stark reminder of the folly of daring to challenge the Imperium.
War Shields		The War Shields are Loyalist Space Marine Chapter of unknown Founding and origins, though some suspect they are descendants of the venerable and unforgiving Iron Hands. This is due to their favoring advanced weaponry and heavy armour during battle. The chapter has gain a reputation of being unrelenting and merciless when on the battlefield, slowly pushing on without fear or remorse when gunning down the enemies of mankind.
Wardens of Annihilation		The Wardens of Annihilation is a Loyalist Space Marine Chapter of the Adeptus Astartes. They possess a storied history characterized by resilience and tenacity. Their origins trace back to M31, during the Great Scouring when they were created from the gene-seed of Rogal Dorn's Imperial Fists. Created during the 3^rd Founding, the newly incepted Chapter was named the "Wardens of Vigilance" due to their dedication to maintaining Imperial vigilance over the Segmentum Solar. This name has changed, however, after the disaster at the Fall of Cadia and their Chapter's threatened extinction; the aftermath of which saw the chapter's remnants rename themselves the "Wardens of Annihilation".
Wardens of the Flame		The Wardens of the Flame is a Loyalist Successor Chapter created during the 10^th Founding from the genetic lineage of the heroic Salamanders. The Wardens of the Flame were created in order to protect the Conchea System, a promethium-rich system located south-southwest of the Annihilus Warp Storm amidst a vast swathe of uncharted space.
Wardens of Orask		The Wardens of Orask are a Codex Astartes-compliant Loyalist Space Marine Chapter of Ultramarines lineage, created during the 7^th Founding sometime during the first few centuries of M34. They were one of several Adeptus Astartes Chapters created to help quell an unknown xenos threat from beyond the Imperium's borders in the Eastern Fringe, known as the Ghoul Stars, which threatened the security of that region of the galaxy. Due to their valiant efforts, they were recognised and fêted by the High Lords of Terra, and were granted the honour of garrisoning the sentinel world of Orask, a battlefront and bastion that has guarded the Imperium from the terrors beyond. A fleet-based Crusading Chapter, since their Founding, this stoic Chapter has willingly answered the call to fight against the myriad foes that have threatened the sanctity of the Imperium of Man across the width and breadth of the galaxy, and as such, have earned the respect and admiration of both the High Lords of Terra and several of their fellow Space Marine Chapters.
Warmachines		The Warmachines are a partially Codex-compliant Chapter specialising in siege warfare and heavy artillery. Clad in old Mark III 'Iron' pattern marks of armour, the Warmachines are ever pragmatic and utilitarian, utilising heavy bombardment, ordnance and overwhelming firepower to crush their foes under an unrelenting hail of munitions and shells. Their chapter warcry "Grind them to Dust" is an example of the manner in which they make war, pounding their opponents over and over until nothing remains but crumbled stone and shattered steel. To the Warmachines, war is nothing more than a series of equations solved by the application of brutal logic and determination. It is not a matter of whether they will win a battle, it is a matter of when.
Warstalkers		The Warstalkers (High Gothic: Bellum Venatorii) are a loyalist, semi-Codex compliant Adeptus Astartes 3^rd Founding Succeussor Chapter descended from the Royal Herculii and bear the gene-seed of the heroic Ultramarine. A fleet-based chapter, the Warstalkers have taken up a duty to safeguard the Imperium's people in the spinward regions of Segmentum Pacificus from xenos, heretics, and traitor Astartes alike. Losing their home world in M39 due to tragic events, the chapter has remaining permanently fleet-borne to the modern era. The Chapter Fleet Taergoracton is constantly on the move, fighting seemingly impossible wars as one chapter or responding to isolated threats spread over a subsector before combing the region for new initiates and moving on.
Wave Breakers		The Wave Breakers are a Codex-compliant chapter comprised entirely of Primaris Space Marines created during the recent Ultima Founding from the venerated lineage of Rogal Dorn. They mostly operate in the Eastern Fringe to safeguard their home system of Pom Merania and keep xenos and Forces of Chaos alike at bay. They are masters in static engagements and often submit multiple companies to a war effort.
Wesroni Hawks		The Wesroni Hawks are an extinct Loyalist Space Marine Chapter believed to have been formed during the 9^th Founding, and are a suspected Successor Chapter of the ancient Salamanders Chapter. Due to separate events involving multiple campaigns against multiple xenos threats that assailed their protectorate region of the galaxy, the Chapter suffered a high rate of casualites, forcing them to withdraw. Due to their inability to raise a sufficient number of new Astartes, and facing a massive Ork invasion of their Chapter home world, the Chapter was reduced to under a hundred surviving battle-brothers. These survivors were then absorbed by their allies from the Night Sentinels Chapter and the Wesroni Hawks were dissolved as an active Chapter.
White Lions		The White Lions are a fully Codex-compliant loyalist Chapter, derived from the ancient Dark Angels. They are very honourable and noble, but are without mercy in battle. In combat they can fight within every range, but they're especially feared in close combat. Their duelling and sword-fighting skills are almost unmatched and they mainly use power-swords to fight their enemies. This Chapter's speciality are sieges and large-scaled battles, where their marshal prowess and tactical minds are at their best. They are a Chapter that, like their founding Progenitors, is very knight-like and resembles these ancient warriors in a lot of ways - from their ships, all the way to their ranking and armour - they are the Knights of M41. Brave and honourable, the White Lions never flee and see retreat as cowardly and shameful. Unique amongst the Chapters of the Unforgiven, they have little to no connection with their founding Chapter, and try to distance themselves from them. They have much better connection with other Chapters, like the Emperor's Legion, with which they share a lot of similarities.
White Kestrels		The White Kestrels are a recently formed Primaris Chapter, successors of the stealthy Raven Guard. Hailing from the planet of Illyria, the surface of which is made up of thousands of floating cloud-islands, every Battle-Brother is a proficient climber and acrobat. This leads them to specialise in Infiltration, delighting in an unassailable fortress or remote bunker. Hot-headed and proud, they have clashed with more experienced chapters on many occasions.
White Paladins		The White Paladins are an ancient and venerated Chapter of the Adeptus Astartes considered to be successors of the venerable Ultramarines. Despite conflicting records regarding their exact founding, many Imperial scholars agree that the chapter has definitely existed since the dawn of M32 From that time they have fought in countless wars across the galaxy, earning the respect of many Imperial commanders and the admiration of the common people. They do not fight for personal glory, however, but merely to do the Emperor's will. The White Paladins are unusual among the Astartes for their admiration of the arts, yet also for their paranoid aversion to fulfilling the desires of the flesh. Through many methods and devices, every Paladin drives himself to let go of an Astartes' inborn pride. However, the truth to their origins may perhaps be the real reason why they seek to excoriate their flesh, seeking to rid themselves of some past misdeed.
White Ravens		Styling themselves an order of chivalry, the White Ravens are a Codex variant Space Marine Chapter of the Ultima Founding created de novo from Greyshield Primaris Marines implanted with gene seed derived from Corvus Corax. Now based on their new homeworld of Londinium, they seek to deliver justice tempered only by mercy, and mercy tempered only by justice.
Wild Hunt		The Wild Hunt ('Asgardsreien' in Veidhamàl) is an Ultima Founding Space Marine Chapter comprised entirely of Primaris Space Marines created from the gene-stock of the feral Space Wolves. This Chapter is based in the Segmentum Tempestus on the first moon of planet Skadi known as Utgard. Known for their tactics resembling a pack of wolves hunting, with deep-strike and infiltration units bleeding their prey dry while the bulk of their forces circles and moves in for the kill, the Wild Hunt carries forth a peculiar variation of Fenrisian folklore, where the cult of Morkai has a prominent place.
Wild Wolves		Hailing from the icy death world of Fjörgyn the Wild Wolves are a particularly savage and bellicose chapter of Astartes, created during the Ultima Founding, descended from the venerable and potent lineage of the feral Space Wolves. The Astartes of this Chapter believe they are deeply touched by the Wild Wolf, the Fjörgynian God of the Hunt. Like their namesake, the Wild Wolves are savage and fiercely aggressive, their blood burning hot with the potent genetic legacy of the Canis Helix within their veins. These warriors prefer to fight at close quarters and are armed with a variety of melee weapons such as chain weapons, power axes and bolt pistols. Notoriously violent and short of temper, they eagerly rush into the fray, slaying their foes in a hail of blood and gore, battering through the deadliest foes and the direst situations to emerge triumphant, time and again.
Wind Runners		The Wind Runners are a Loyalist 10^th Founding Chapter of the Adeptus Astartes who are descended from the lineage of the savage and proud White Scars Chapter. The Chapter is most well known for their precision execution of the various forms of combat listed in the Codex Astartes. Their most prevalent form of combat is their bike or mobile forces, which are known to zoom into the battlefield, ready for a fight. The Chapter has known hardships and loss over the span of a millennia, with many of their victories being in defense of their home planet, Hinduja Velo, and in service of the Emperor when humanity requires defending.
Winds of Fury		The Winds of Fury are a loyalist Codex-compliant Successor Chapter created from the proud lineage of the revered Raven Guard during the 23^rd Founding, the so-called 'Sentinel Founding'. This near mysterious chapter was created following the liberation of Ryunkai against the Orks of Klan FaceChoppa by the famous Shadow Captain Alerin of the Raven Guard's 3^rd Company. The chapter continues to practice the art of stealth, guerrilla warfare and close-combat using the combined teachings of their ancestors while fighting the "Green Oni", aka the greenskins, and the wisdom of the Raven Guard Chapter. The chapter is known to operate independently and never depends on any other chapters aside from those that earn their respect.
Winged Axes		The Winged Axes are a loyalsit Space Marine Chapter of the Adeptus Astartes created during the 12^th Founding from unspecified lineage. This Chapter was created for one task: guarding the Veiled Region. The Veiled Region describes a region southwestern of Segmentum Tempestus where the light of the Astronomican in the best case is just a fraction of its strenght if not already depleated. Unfortunatly for the Imperium can the local xenos forces travel without the Astronomican and have repeatently invaded imperial Space. Space Marines from the Winged Axes are stand eternally on constant alert for new incursions and for retribution operations. Furthermore, they are known for the raiding and occupation of smuggler vessels and illegal settlements providing some ressources and further support from the Segmentum Command.
Winged Knights		The Winged Knights are a Loyalist, non-Codex-compliant Space Marine Chapter drawn from the lineage of the vaunted Blood Angels during the 4^th Founding. Though their lineage is clear, the exact Chapter from which they can claim to be the successors of is not. It has long been suspected that they are a Successor Chapter of the Angels Sanguine, the truth of that suspicion has yet to be confirmed. Though they were a Chapter of great honour for approximately two millennia, the stain of heresy has marred their reputation and they have never been able to escape the its legacy.
Wings of Judgment		The Wings of Judgment are a mysterious and aloof Chapter of the Adeptus Astartes, of unknown founding and uncertain origins. However, due to their similar fighting style and preferred tactics, they are considered by Imperial savants to a probable Successor Chapter descended from the lineage of the Raven Guard Primarch Corvus Corax. A bellicose and unforgiving Chapter, the Wings of Judgment have garnered a reputation as zealous persectutors of those whom would turn from the Emperor's light. However, due to their aloofness and belligerent attitude they have often been accused of wanting of brotherhood, and often other Imperial military forces will refuse to serve alongside them.
Wings of Ryuk		The Wings of Ryuk are a Chapter of Adeptus Astartes, hailing from the noble lineage of the Ultramarines. Drawn from a tribe of savage human warriors who share their home planet with a humanoid species known as the Reech Folk that are remarkably close to baseline human D.N.A, who seemed to be just as savage as the Astartes of the chapter. Most Astartes say that these Reech Folk are responsible for the chapter’s behaviour as the humans before their time as Space Marines coexist with and are adopted into the culture and even what was at the time an "non-sanctioned" religious belief. Though their exact origins are disputed, it is generally believed that the Wings of Ryuk were created duirng the 3^rd Founding.
Wings of Salvaxes		The Wings of Salvaxes, in their brief existence as a Space Marine Chapter have carved for themselves a vicious and brutal reputation for wanton slaughter and savage violence. Alone they stand amongst the noble Sons of Sanguinius as dark pariahs of all that the Blood Angels lineage seek to avoid. Eschewing the jump pack assaults of their Primogenitors and sister chapters, the Wings of Salvaxes instead make use of massed mounted charges, spewing forth death from their guns unhindered by their savage recoil, before crashing into their foes like an avalanche - chainswords hacking and wheels crushing all that stand in their way. Their momentum expended, they will peel away from the assault as their psychotic Death Company terminators join the fray in a bloodbath of blasting stormbolters and crackling power fists. They will then either roar off to find more foes, or circle around and join their terminator brethren in the slaughter of the Emperor's foes.
Wolfborn		The Wolfborn are a Successor Chapter of the Space Wolves, created during the Ultima Founding of 999.M41. Comprised entirely of Primaris Space Marines, these Drengr of Russ were created to support the forces in Segmentum Ultima.
Wolfpyre Wardens		The Wolfpyre Wardens, affectionately known as the "Stormborn Guardians", epitomize the enduring legacy of the Space Wolves. This successor chapter emerged during the later stages of the Ultima Founding, a time when the Imperium urgently required new Space Marine chapters to safeguard its vast domains. Forged in the crucible of battle and infused with the unwavering spirit of their forebears, the Wolfpyre Wardens share the same unyielding loyalty to the Emperor of Mankind and the savage nobility that defines their predecessors. Much like the Space Wolves who came before them, they have garnered a formidable reputation for their brutal combat strategies, unbreakable camaraderie, and relentless devotion to the Imperium's cause. While the Space Wolves are renowned for their deep ties to the icy realm of Fenris and their affinity for extreme environments, the Wolfpyre Wardens have charted their unique course amidst the stars. They have honed their expertise in adapting to the diverse cosmic landscapes, be it frozen tundras, arid deserts, or the cold void of space itself.
Wolf's-Head Marines		The Wolf's-Head Marines are a non-Codex compliant Space Marine Chapter created during an Unknown Founding and of uncertain lineage. Despite their liberal use of the wolf iconography in their heraldry, there seems to be no connection to the ancient and feral Space Wolves.
Wolves of Dantra		The Wolves of Dantra are an ancient loyalist Successor Chapter of the Ultramarines created during the 2^nd Founding in the wake of the tragic events of the galaxy-wide conflict of the Horus Heresy and the subsequent Great Scouring in 021.M31. Since their inception, the Wolves of Dantra have become renowned for their shock and awe approach to urban warfare. They have fought for the imperium for many millennia over a variety of conflicts bringing death and destruction to the enemies of man.
Wolves of Redemption		The Wolves of Redemption is a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created from the lineage of the Space Wolves and raised during the Ultima Founding of 999.M41. After the disbanding of the Unnumbered Sons, the Primaris Space Marines of Leman Russ's lineage became members of either the Wolves of Redemption or other successor of Leman Russ. Like their brother-chapter, the Wolfspear, the Astartes of the Wolves of Redemption fear that the Space Wolves will not see them as 'true inheritors of the legacy of the Wolf King. Though they know that some Space Wolves have accepted Primaris Space Marines like them into the ranks of their Chapter, they that some of the Space Wolves have denied the Primaris Astartes and their right as 'true inheritors' of the legacy of the Wolf King.
Wolves of Retribution		The Wolves of Retribution are an infamous Chaos Warband that was formerly a Loyalist Space Marine Chapter created during an Unknown Founding and from uncertain lineage. There are many tales of loyal Chapters falling to the temptations of Chaos. Some falls are obvious, such as the infamous Crimson Sabers, while others are surprising. The fall of the Wolves of Retribution falls into the latter category. Once, they were proud heralds of the God Emperor but now they are heralds of damnation. It is perhaps the greatest misfortune that the Wolves of Retribution cannot see what they have become. They still see themselves as the loyal warriors of the Emperor, blind to the chaotic corruption that warps their armour, twists their flesh and perverts their scripture. The angels they fight alongside are daemons of the Octed. Even the fire they hold sacred has been turned by the warp, damning the souls they claim to save. (Excommunicate Traitoris)
Wolves of Terra		The Wolves of Terra are a Loyalist Space Marine Chapter of the Adeptus Astartes created during the 4^th Founding in the middle centuries of M32. Created from unknown lineage, the origins of their gene-seed has been classified at the highest levels. Savage, highly aggressive and relentless are words that best describe the Wolves of Terra in combat as well as their independent nature, as they are only a semi-Codex compliant Chapter. Since their inception, the Wolves of Terra have garnered a reputation as a bellicose and savage Chapter, ruthlessly slaughtering the enemies of Mankind with the chapter's prefered weapons of chain-axes and chainblades.
Wooden Vityaz		The Wooden Vityaz are a Sucessor Chapter of the stoic Iron Hands created during the 22^nd Founding, though trough their turbulent early history they turned out very different to how the High Lords of Terra intended them. Superficially they might resemble a Dark Angels or even Space Wolves sucessor more than one of the Iron Hands, but their demeanor, organisation and gene-seed abnormality bind them clearly to their progenitors. The Chapter's focus on melee and, in many ways, feudal or tribal culture are not that unusual. What is unusual, however, is their chapter-centrist worldview. They serve the Chapter formemost and serve the Imperium, as that is the best for the Chapter, with loyalty towards the Imperium in second place or possibly even third if one counts Clan loyalty.
World Marauders		The World Marauders are a Loyalist Space Marine Chapter of the noble White Scars formed during 23^rd Founding, also known as the 'Sentinel Founding'. A fleet-based Chapter, the World Marauders move as a singular powerful force, striking planet after planet filled with the enemies of mankind. Space fairing, they do not adhere to the authority of the Imperial higher-ups, seeing them as weak-minded and corrupt. They have garnered a reputation of attacking human pirates, recruiting from their ranks or forcing others to become their serfs.
Wyverns		The Wyverns are a partially Codex-complaint Loyalist Space Marine Chapter and successors of the White Scars. The chapter was created during the 4^th Founding in the aftermath of the War of the Beast in the middle centuries of the 32^nd Millennium. The Wyverns' name and chapter symbol are derived from the huge reptilians that soar above the wilderness of their homeworld, Rhos. In the wake of the opening of the Great Rift, Rhos' strategic location near the Nachmund Gauntlet - one of the only known safe passages through the Great Rift - has the Wyverns taking the additional responsibility for the security of the passage.

Zealot Scythes	Pict-File Unavailable	The Zealot Scythes are a Loyalist fleet-based Chapter of Space Marines on a never ending crusade, created shortly after the Reign of Blood during an unknown founding using the gene-stock of the Primarch Vulkan, to destroy those who would go against the Ecclesiarchy. They often teeter between outcasts and brutal allies with most Imperial organizations, constantly carving a scorched path of devastation across those that turn from the light of the God-Emperor regardless of who they may be.
