Name 	Iconography 	Image 	Notes
Adventurer’s Guild 	 	 	A non-Codex Compliant fleet-based Chapter designed to work with and meet the needs of Rogue Traders.
Aetherian Warriors 	 	 	The Aetherian Warriors are a Codex-compliant chapter derived from Blood Angels genestock and formed in the Twenty-Fourth Founding in M40. While originally meant to simply bolster Imperial forces on the border of Segmentum Obscura and the Ultima Segmentum, their reach wound up far exceeding their original purpose, partaking in some of the most pivotal campaigns and crusades in the late 41st and early 42nd millennia, including the Ulgroth Crusade, 13th Black Crusade, and the Indomitus Crusade.
Angelus Misericordiae	Pict-file unavalible 	Pict-File unavalible 	The Angelus Misericordiae, or the Angels of Mercy in Low Gothic, are a mysterious Chapter of apparent Blood Angels descent. With little to no official records to be found of their existence, their knowledge is mostly restricted to the upper echelons of the Great Angel's sons, and their appearances seemingly dictated by portents of the Emperor's Tarot.
Armor Fiends 	Pict-file unavailable	Pict-file unavailable	The Armor Fiends are a crafty renegade Chapter founded in the 20th founding. Rushed out as a stop gap measure, their turn away from the Imperium was inevitable. The chapter was a mess from the start. Being forced in to combat with another chapter that simply were not ready for combat alone. Since then, the Armor Fiends have fought many sieges for and against the Imperium.
Astral Dragoons 	 	 	The Astral Dragoons are a Codex Astartes Space Marine Chapter created from unknown gene-seed stock during one of the early Foundings. The Chapter is mostly involved in battling against Eldar, however they also fight against Orks, Chaos and Tau. The Chapter's current location is unknown, however some say they are fighting against the Tyranids in the Ultima Segmentum, which is where they were last seen.
Astral Fangs 	Pict-file unavailable	 	The Astral Fangs are a Space Marine Chapter founded during the 23rd founding. They are a chapter that tends to stay isolated on the fringes of the Imperium. They have been known to work closely with the Ordo Chronos of the inquisition.

Axe Brothers 	 	 	The Axe Brothers are a devoted, noble and mighty Chapter, having battled throughout their millennia long existence from their Ultramarines Legion roots, to the current date and timeline. Forged in the fires of war and betrayal of the Horus Heresy, they were created following the subsequent sundering of the original Space Marine Legions during the Second Founding in 001.M32. The newly created Axe Brothers Chapter were placed under the command of Legion-Captain Roman, the former commander of the Ultramarines' 7th Company. After slaying the World Eaters Chaos Champion Kronlovk, he proved himself a worthy leader and was giving the right to lead his very own Chapter after the Horus Heresy.

Basilisks 	Pict-file unavailable	Pict-file unavailable	The Basilisks are a secretive Chapter created from unknown origins and Founding. This Chapter's arrival is often considered an ill omen by their fellow Astartes, and as a sign of the end for many Imperial Citizens. Allegedly cursed, they specialise only in one form of combat; Scorched Earth tactics. Utilising fire, rad weapons, and chem munitions, they salt the earth and slay any in their path.
Black Orthodoxy 	 	 	The Black Orthodoxy Chapter is a religious loyalist Chapter with a strong connection to both the Ecclesiarchy and the Ordo Hereticus. They allow no psykers amongst them and employ many pariahs (psychic blanks) as battle brothers to combat them. They are an stern, odd, reclusive, secretive, and slavishly devoted to the Emperor.
Blood Dragons 	Pict-file unavailable	Pict-file unavailable	The Blood Dragons are a Successor Chapter of the vaunted Blood Angels, and serve as one of the wardens of the far-flung Tyrest Sector, containing worlds of importance to the Imperium, but imperiled by threats on all fronts.
Blood Fiends 	Pict-file unavailable	Pict-file unavailable	The Blood Fiends are a loyalist chapter composed entirely of Primaris Space Marines. They served in Roboute Guilliman's Unnumbered Sons army during the Indomitus Crusade until the army was disbanded and its members were split into chapters of their own. The Blood Fiends were one of these chapters and continued to fight against the enemies of the Imperium after the conclusion of the Indomitus Crusade.
Bone Guard 	Pict-file unavailable	Pict-file unavailable	The Bone Guard are a codex compliant Successor Chapter of the Imperial Fists. Founded during the 27th founding, these melee combat experts guard the bones and final resting places across the Imperium.

All the while Apothecaries and other Marines gather the bones of there fellow Brothers, as well as those who were witnessed dying heroically in the name of the Emperor.
Brotherhood of the Mammoth	 	 	The Brotherhood of the Mammoth was at one point a doomed company, lost and stranded upon a feral death world known as Kor, thought lost to time. They were reclaimed, after generations had passed, and now these feral space marines serve the Emperor once again.
Brothers of the Grid 	Pict-file unavailable	 	A brash chapter that draws heavily from the stock of highly competitive athletes. They fight in a highly unorthodox fashion but their sheer physicality and skill born of competition leads them to be highly regarded.

Cadre of the Horn 	Pict-file unavailable	Pict-file unavailable	Data unavailable
Cerulean Executioners 	Pict-file unavalible 	Pict-File unavalible 	A Third Founding Imperial Fists successor Chapter devoted to destroying the traitor legions. They have a good relation with the Redeemed space marine chapter and the Death korps of Krieg. They were nearly destroyed by the 13th Black Crusade with only a third of the chapter surviving the Fall of Cadia only being saved by Roboute Guilliman and the Indominus Crusade.
Crimson Serpent Raiders	Pict-file unavailable	 	A strange band of space marines that are non-codex compliant. Their origins are entirely unknown. The last thing they can remember is waking up in cryo pods onboard their flagship with one goal in mind, Terra. When they arrived, they discovered a message left by their previous Chapter Master. The message instructed them to find and reawaken the dormant ships that once made up their massive fleet. Now all that they can do is wander the galaxy and hope that when their chapter is restored to its full strength an answer will be revealed to them. As for their tactics, they excel in naval combat, taking heavy influence from the pirates of old. Masters of boarding tactics, 20 to 30 pods may be sent out in a battle to wreak havoc. Their ships range from hulking beasts of metal clad in heavy armor, armed with massive cannons that devastate enemy ships armor, to nimble bombers that hurtle from one end of a battle to another in seconds, blasting every exposed component to kingdom come, to carrier ships that deploy the vast array of boarding parties. All of these are commanded by a great flagship, capable of housing all of the Raiders' fleets. On the ground and when boarding they use great brutality to instill fear into the hearts of their enemies, they favor neither melee nor ranged combat but they avoid using psychic powers. Their tactics have proven quite effective against human traitors, Eldar, Tau, and Orks. With such reliance on fear tactics, they shouldn't be so effective against Orks, but with their exceptional talent with hand to hand brutality, they often fight one on one, with the highest-ranking of both sides duking it out for the right to claim success in their respective missions and given any and all spoils. Though they are quite brutal, they uphold a code of honor. They see Orks as worthy opponents to their unending love of combat. When they win battles they often scrap and reuse any broken weapons and armor for their cause. They don't have a homeworld and simply live nomadically in their fleet.

Death Cult 	Pict-file unavailable	Pict-file unavailable	The Death Cult was a Blood Drinkers successor chapter from the 8th founding that was the result of an attempt to quell the Red Thirst. They were conscripted to explore new options to try to cure the Red Thirst and explore options for enduring it. The Death Cult was destroyed during the Cursed Saint Crusade but their legend lives on in the halls of the Blood Angels and their successors.
Dire Bears 	Pict-file unavailable	 	The Dire Bears are a Primaris Space Marine chapter born of the Indomitus Crusade from Space Wolf geneseed the Dire Bears distinguished themselves as cunning masters of sustained operations. They are at odds with their parent chapter and are feuding with the Wolfspear chapter.
Dune Dragons 	Pict-file unavailable	Pict-file unavailable	An enigmatic and ancient Chapter of Space Marines, the Dune Dragons have long been a mystery amongst their fellow Astartes. Hailing from the sweeping deserts of the Feudal World of Ak'Une, known as Isisar Majoris in the standard Imperial Lexicon, the Dune Dragons are warriors who prize swiftness, durability, and precision above all else in battle. Soaring into battle within their vast Land Speeder squadrons, or crushing through enemy ranks with their mighty Predator Tank formations, the Dune Dragons place the utmost faith in the Machine Spirit, venerating the Omnissiah equally with the Emperor, holding them as parts of the same being.
Dragons Sanguinaris	 	 	The Dragons Sanguinaris are a non-Codex compliant Space Marine Chapter composed entirely of Primaris Space Marines, created in the 27th 'Ultima' Founding, and descended from the Blood Angels. They favour a 'soften-and-smash' approach to battle, deploying Jaberwockis (Hellblaster units) from Wyrms (Land Raiders) alongside Amphitheres (stormraven gunships) and Wyverns (Interceptors). Then in the middle of the fight, once the enemy force has been weakened and diminished by the initial forces, drop pods descend from the sky behind enemy lines, and deploy Kholeghan squads (Primaris Reivers).

Emancipators 	Pict-file unavailable	 	The Emancipators were a unit in the Primaris Legions during the Indomitus Crusade that was later, briefly, founded as a small chapter during the Plague Wars that followed. Their legendary service ended in bittersweet gallantry and with that they earned themselves a place in the pages of Imperial history.
Emperor's Sabres 	Pict-file unavailable	Pict-file unavailable	Data unavailable
Emperor’s Servants	Pict-file unavailable	 	The Emperor's Servants are a 4th founding chapter of Ultramarine stock. Their entire mindset revolves around service and humility. All of their thousand marines work the fields on their lush homeworld, farming with their attendants and even members of the local population. Warriors first, they always spend a little time on civil projects and are beloved by the people of the worlds they protect. They employ a large number of apothecaries and have some of the lowest casualty rates of any chapter as a result. They establish hospitals on many worlds and are particularly adept at combating the forces of Nurgle because of their advanced medical skills.

Fire Lions	Pict-file unavailable	Pict-file unavailable	Once a fiercely loyal Chapter of the Dark Angels' Unforgiven, the Fire Lions turned from the Imperium they had sworn to uphold during the dark days of the Nova Terra Interregnum, supporting those who opposed the establishment of a theocratic state and succession from the Imperium and its new Imperial Cult. However, after the Ur-Council crumbled, the Fire Lions were forced to flee with scores of refugee fleets to the very borders of Segementum Pacificus. It is said by Imperial scholars that the Fire Lions still reside in the deep space at the edge of the Galaxy, having formed a small fleet based nation-state based on the edicts of the Imperial Truth. Now little more than vagabonds and pirates, the Fire Lions seek to rekindle a rebirth in the Imperium's golden age of reason through brutal terror strikes and by seeding the stars with agents of doubt.

Gold Templars 	center|180px 	 	The Gold Templars are a Space Marine successor Chapter created in the 25th 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 characterised 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 rather weak psykers. 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 Reclaimers	 	 	The Golden Reclaimers are an Imperial Fists successor Chapter formed in the Twenty-Sixth Founding. A newer group of Space Marines, they have accomplished a great deal in their few centuries of existence and are known for their loyalty towards Mankind. They were created in 738.M41 in order to help seize a number of worlds that the Imperium had lost contact with over the years, hence their title as 'Reclaimers'. The Chapter would end up dealing with a number of foes during their early years and became particularly adept in the art of urban warfare as world after world was reclaimed in the name of the Emperor.
Golems 	Pict-file unavailable	 	The Golems are a loyalist 21st Founding Chapter. Their genetic quirk causes their black carapace, once installed, to turn stone-like and grow uncontrollably across their flesh. Their armor, if it is worn long enough, becomes covered in the craggy stone and missing pieces are replaced by the mutated stone carapace- unable to be removed. Many have their attendants regularly chisel them so that they might keep a normal appearance but some within their ranks let it run wild.
Grave Bearers 	 	 	The Grave Bearers are a successor to The Black Templars and despise Psykers. The Grave Bearers derive their name from the ritual practice of engraving the names of fallen brothers on the inside of their armor. The battle brother is cremated and the armor is past on to the next. Since there is no body to bury and no headstone to mark, the armor itself becomes the grave for the fallen brother and the new owner has to carry the burden and honor of those that wore it before him.
Grey Eyes 	Pict-file unavailable	 	Ancient and terrible are the Grey Eyes. From the earliest days of the Imperium they served the Emperor and his primarchs. It is recalled not from whom they descended but their doctrine is unique and their actions gallant. They are famous as they are mysterious- appearing at times when it is most important for the Imperium. They follow an ancient and sacred scroll of prophecy that legend says was penned by the Emperor. The Grey Eyes are believe to be following a secret plan of the Emperor to help guide the Imperium though some future crucible.

Hunters	 	 	The Hunters were a Codex-complaint Space Marine Chapter of Ultramarine descend who claimed the jungle/death world of Jewel as their homeworld before their exile from the realm of Ultramar. They would later settle on the Civilized World of Ionov. The Hunters were founded as part of the 10th Founding during the Nova Terra Interregnum. The Hunters were known for preferring the Stalker Pattern Boltgun over more common patterns of Bolters used by the Adeptus Astartes as well as other long-range firearms.
==I==
Name 	Iconography 	Image 	Notes
Imperial Shields	Pict-file unavailable	 	The Imperial Shields are a unknown successor chapter who don’t follow the Codex Astris, and are not what the Inquisition call “loyal enough” to the Emperor. To the people of the under the Emperor they protect them like the Salamanders and recruit from humans, xenos, and the Tau for which the Inquisition has called them heretics and has ordered their destruction, but they are Allie’s with the Salamanders, the Raven Guard, and the Reasonable Marines, with their chapter master Brother Gunnwulf Von Stone who leads a number of planets and hive worlds into a stable and peaceful way.
Imperial Uhlans 	Pict-file unavailable	 	The Imperial Uhlans are a 23rd "Sentinel" Founding successor of the Imperial Fists, specializing in mechanized and armored warfare. The Chapter has a bitter vendetta against the Nurglesque warband known as the Lords of Rot, as the warband was founded when the Chapter's entire Apothecarion turned to Chaos in the late 38th Millennium.
Iron Brotherhood	 	 	The Iron Brotherhood (Frrum Fraternitati in High Gothic) are a crusading Chapter, spending years at war, only to return home and celebrate with tales of conquest, and battles won. Counting themselves amongst the sons of Dorn, they lack some of their sombre, stern traits, replacing it instead with a joy for combat that they wear upon their sleeve. Like their progenitors, they place great focus on martial skill, and are renowned for having iron-wills, strong discipline, and being stubborn in battle. They are known as both crusaders, and heroes, placing greater focus on protecting the citizenry of the Empire, more than most other Chapters.
Iron Heralds 	Pict-file unavailable	 	Children of the Indomitus Crusade, the Iron Heralds are descended from the harsh Iron Hands chapter though they couldn't be more at odds their their progenitors. What they share is a need to tinker, though not with machines but with the mind. They have been called the "will breakers" and "man-slavers" for their destructive shock propaganda and torture techniques.
Iron Seraphs 	Pict-file unavailable	Pict-file unavailable	Data unavailable
Ivory Wardens 	Pict-file unavailable	 	The Ivory Wardens are a Raven Guard successor Chapter of the 23rd "Sentinel" Founding.

Jade Falcons	Pict-file unavailable	Pict-file unavailable	The Jade Falcons are a Successor Chapter of the venerable Dark Angels. They were created during the 3rd Founding from the gene-stock of Lion El'Jonson. Like their fellow Unforgiven Chapters, they continue with their secret hunt for the Fallen Angels, scouring the galaxy for their erstwhile kin, so that they can grant them extreme unction at the hands of their forebear's Interrogator-Chaplains.
Jade Vipers 	center|180px 	 	The Jade Vipers are an Ultima Founding Chapter established ca. 999.M41. Unlike most Ultima founding chapters the true Gene lineage of their founding is not fully known with dark whispers being they are from Gene Stock that Belisarius Cawl had access to but was ordered not to utilize. Even with their possible Dark Lineage the Vipers have proved themselves time and again especially in the arts of close combat and in particular close quarter areas such as jungle warfare thanks in no small part to their chosen Chapter Home World of Yuc'anti XIII.

Knights of Retribution	Pict-file unavailable	Pict-file unavailable	Data unavailable
Knights of Sanguinor 	Pict-file unavailable	 	The Knights of Sanguinor are one of the Second Founding Chapters, created from the vaunted Blood Angels, their initial founding members were primarily made up of Legionaries from the 167th Company. They are well-known across the galaxy for their stealthy nature in battle, and didn't fear for the curse of the flawed gene-seed they carry. The Knights of Sanguinor are amongst the longest-living of the Adeptus Astartes, with some of the Chapter's Space Marines having served the Emperor of Mankind for over a thousand standard years.
Knights of the Lion 	 	 	The Knights of the Lion are a Successor Chapter of the venerable Dark Angels. They claim to be one of the ancient Chapters created during the Second Founding in 001.M32. They are considered to be amongst some of the greatest of combatants against Chaos and other renegades. Their outwardly rowdy and somewhat friendly exterior for a Space Marine is unusual for a descendant of the First legion, however, their enemies would be wise not to confuse the Knights' jolly demeanour for weakness or mercy. On the battlefield the Knights of the Lion are relentless -- their enemies defeated in battle are often completely obliterated -- as the Knights utilise Terminators, jump packs and Drop Pods to ensnare and engulf their foe. Rarely does an enemy warlord or opposing commander escape the judgement of this Chapter of the Unforgiven. The Chapter has taken record numbers of fallen back to Lionswatch and their Interrogator-Chaplains are second only to the Dark Angels themselves at extracting confessions.

La Grande Tempête	 	 	La Grande Tempête or "The Great Storm" chapter was a 3rd founding chapter of the Ultramarines. The Chapter had a singular goal, the destruction of a gate that lead to the Immaterium known as "The Great Storm". It drew its members from many Ultramarine successor Chapters and a small complement of their own genetic stock. They were disbanded after their long vigil and the closure of the gate.

Name 	Iconography 	Image 	Notes
Makemake 	Pict-file unavailable	 	The Makemake Marines are a Loyalist Space Marine Chapter of the 23rd Founding. Their home planet of Rapa Nui is a paradise world comprised almost entirely of water. Only about 5% of the land’s surface is solids and the Makemake have used this to their advantage, training as aquatic commandos beneath their homeworlds waves. The oceans of Rapa Nui are very deep (about twice as deep as Holy Terra's) and the pressure at the deepest depths, where their Fortress Monastery Anakena Reef is enough to crush steel. The Makemake are expected to spend almost all of their time out on the sands of the ocean- making landfall only when necessary. All their training is done under the sea and this has expanded the capacity of their multi-lung (aka the imbiber)- allowing them to more easily breath underwater than other chapters. While underwater they sub-vocalize their speech, the vibrations picked up and transmitted to their brother marines. This habit persists even while on land, earning them the nicknames of the “silent marines”.
Marines Magnus 	Pict-file unavailable	Pict-file unavailable	Declared Lost. Possibly refounded.
Marines Mercantile	Pict-file unavailable	 	The Marines Mercantile are a 14th Founding Chapter of unknown descent who were created at the behest of the Adeptus Administratum. Their role is primarily to escort especially high-value cargo from one location to the next. While not officially a part of the Administratum they are in effect, the Administratum’s sword arm where interstellar commerce is concerned. Marines Mercantile squads accompany things like relics, large tithes, VIPs, either in a direct fashion (to dissuade rebels and other dissidents from attacking the shipment) or covertly (to spring a trap on pirates, when their presence would attract attention to secret cargo, etc). They are made to be seen, adorned in metallic brass/gold colored power armor they always make a statement; the cargo is under their protection.
Marines Triumphant	Pict-file unavailable	 	Despite originating during the "Cursed" 21st Founding, the Marines Triumphant served several Millennia without any apparent genetic abberation, likely thanks to the stability of their Ultramarines genestock. However, in the early 41st Millennium, the Chapter was cursed by a daemon they were called to vanquish on the Agri-World of Jathea XII, leaving their progenoids incapable of producing new geneseed, damning the Chapter to a slow and agonizing death.
Megamarines 	 	 	After the War of the Beast the Imperium authorized the 4th Founding. The Megamarines were founded as a fleet-based chapter with a unique specialty; they were born from the Imperium’s need for specialized void-combat unit. The Megamarines were designed as a fleet-based boarding, repelling action, and orbital insertion chapter. Their main methods of attack regularly employs zero/low gravity environments and are masters of space naval combat.
Messengers of Fire	Pict-File Unavalible 	Pict-File Unavalible 	The Messengers of Fire are a 3rd Founding Space Marine Chapter of Blood Angels stock. They firmly preach the humanity of the Emperor which has brought them to open conflict with the Adepta Sororitas. They are stationed in the Segmentum Pacificus to protect against Ork invasion. They have a special steed that is large enough to hold a fully armored space marine.

Nemesis Knights 	Pict-file unavailable	Pict-file unavailable	Data unavailable
Nevonian Free Company	Pict-file unavailable	 	This is a story about the Nevonian Knights, a once proud chapter who fell victim to a war with the Tyranids that ground them down to just under a company in strength. Despite their sacrifice they failed in their mission, 4 worlds falling to the ravages of the endless waves of xenos. In penance they became a crusading chapter, simply seeking a good place to make their final stand. They, however, were cursed to live in their shame and would not fall in battle. Eventually they were joined by others- the disgraced, the injured, and the damned who sought to find a way to do honor to the Emperor with their death. So it was that the Nevonian Knights, called the Nevonian Free Company by those who know of its true nature, began its eternally suicidal crusade against the enemies of the Emperor.
Nemean Lions 	 	 	Created during an unknown Founding in the early years of the 38th Millenium, the Nemean Lions have fought in most of the major conflicts of the Galaxy since their founding, from Cadia to Armaggeddon, the Gothic War, the Macharian Crusade and the Indomitus Crusade. A Chapter with a impressive history despite its relative youth, they seem to be paragons of loyalty and purity. Well hidden beneath the surface however lie internal divisions and potentially heretical revelations.
==O==
Name 	Iconography 	Image	Notes
Order of the Stone Lion	Pict-file unavailable	 	A Chapter forged in the fire of the Indomitus Crusade, the Stone Lions were a small relatively unknown chapter of White Scar descent prior to the Ultima founding when they were reinforced by a large contingent of Primaris marines. They are unusual in that they specialize in hand to hand fighting and are noted for being particularly limber. They have little contact with other White Scar successors and, in fact, are fiercely independent even from their chapter members. A strict code of martial honor dictates their everyday life and honor bouts are common among the battle brothers.

Peacemakers 	 	 	The Peacemakers are an Adeptus Astartes Chapter originally made up of Firstborn and now comprised of solely Primaris Marines founded during an unknown Founding. The Peacemakers are masters of air-to-ground warfare and shock assault, favouring the assault variants of battleline infantry. Borne from the gene-see of the their forefathers, the White Scars, the Peacemakers defend the Imperium from agents of Chaos and the xenos threat. Headquartered on the dusty, blood-red sand planet Acheradon, the Peacemakers learnt to travel the dense sand dunes of their planet.
Palatine Warriors	 	 	The Palatine Warriors are Fleet-based 25th Founding successors of the Ultramarines. Known for their puritanical beliefs and a narrow, inflexibile interpretation of the Codex Astartes, the Palatine Warriors have made few friends in the Imperium, but have managed to forge unusually close ties with the Ecclesiarchy.
Phoenix Knights 	 	 	The Phoenix Knights are a newer Founding Chapter, created from the gene-stock of the venerable Dark Angels during the Twenty-Sixth Founding. Initially named the Knights of Vengeance, this Unforgiven Chapter faced an inauspicious beginning, and would have been destroyed in its entirety when they were attacked by a large Chaos warfleet and beset upon by daemons during a routine warp jump. Though the majority of the newly created Chapter's most experienced Astartes perished, they managed to turn the tide and snatch victory from the jaws of defeat. Displaced by the vagaries of the Warp, the Chapter reemerged into realspace after missing for nearly three centuries. Their exposure to the energies of the Warp also caused mutations in the gene-seed, the full extent and implication of which were not yet clear. Therefore, the Knights of Vengeance were declared corrupt and unworthy as inheritors of the Lion, and so, the Dark Angels severed all ties with their former kin. In their darkest hour, the Ultramarines offered to help rebuild the shattered Chapter as well as stabilising the minor degradation in their gene-seed. Thus, the Chapter rose from the ashes like the fiery bird of ancient legends -- the Phoenix -- thus, the Knights of Vengeance forged a new identity and became the Phoenix Knights.

Radiant Horns 	Pict-file unavailable	Pict-file unavailable	The Radiant Horns are a loyalist Space Marine Chapter tasked with patrolling the Caligari Sector of the Segmentum Tempestus.
Rangers 	Pict-file unavailable	 	During the cursed 21st Founding forces within the Imperium attempted to covertly steal the coveted ability to navigate from the Navis Nobilite by secretly implanting their genetic traits into a group of space marines. While the result was nominally successful at first and the chapter appeared to be unblemished beyond their manifestation of the warp eye, they began to slow increased arrogance, grotesque mutations, and an unnatural wanderlust. After several failed attempts to correct this, and to keep the secret of the stolen genetic information, the High Lords of Terra ordered the chapter to go on an eternal crusade among the farthest stars in the galaxy.
Redemptor Crusaders	Pict-file unavailable	 	A 37th Founding Chapter, speculated to be of Blood Angel stock.
Revenants 	Pict-file unavailable	Pict-file unavailable	Data unavailable
Royal Marines 	 	 	Sometime after 987.M41, a special program was begun by the High Lords of Terra. The Massacre at Big Toof River, the complete destruction of 2 Praetorian Guard regiments by Orks on Montar VII, showed the Imperium that the genetic stock of such soldiers should not be wasted. So it was that, in secret, they began to "kill" some of the most promising young recruits of the Praetorian Guard and use them to found a new Space Marine chapter. The result was the "Royal Marines", a chapter where tradition, discipline, and valor were prized above all else.

Serpent Skulls 	Pict-file unavailable	 	The Serpent Skulls are a renegade yet loyalist Space Marine Chapter speculated to have been founded sometime before the War of the Beast, for it was during this war that they first appear in Imperial records. They would become renegades during M38 due to them being declared heretics after saving Aeldari exodites from the Emperor's Children. The chapter would later infiltrate and attack the Invaders space marine chapter alongside the forces of Alaitoc in revenge for destroying the craftworld of Idharae. They became enemies of Yvraine, who they blame for killing their old Chapter Master and made a deal with Asdrubael Vect to kill Yvraine. But broke it after the Resurrection of Guilliman. They were lastly seen aiding the Ultramarines and Roboute Guilliman under their new Chaptermaster during the Indomitus Crusade.
Scourers 	Pict-file unavailable	Pict-file unavailable	Data unavailable
Shrikes 	 	 	The Shrikes, sometimes referred to as the “Bloody Shrikes” or “Oni Marines”, are a 13th founding chapter of Raven Guard heritage. Over time this chapter developed an overactive Omophagea organ that allows them to glean genetic information by touch. They are cruel, efficient, assault-specialists with little regard for the lives of Imperials who get in their way.
Silent Gnosis 	Pict-file unavailable	 	Founded during the Ultima Founding, the Silent Gnosis Chapter is very close to its originator- the Dark Angels. However, this chapter has a very unique relationship with them; Silent Gnosis is intentionally not told any of the chapter’s secrets. “To Know is to Be Unclean” is their motto (“Gnosis” being an ancient word for knowledge) and they do the dirty work the Dark Angels and the other unforgiven can’t because the knowledge of the great secret would preclude them. Silent Gnosis is the chapter that is dispatched when one of the successor chapters is needed to work with the Inquisition or if there is some great risk of a brother marine betraying their secret.
Sons of Gwydion	Pict-file unavailable	 	The Sons of Gwydion are a 26th Founding Chapter who have a penchant for being malicious tricksters. Their sardonic wit and grim humor are only matched by their faith in the Emperor and creative battle plans. The Sons of Gwydion are a storied chapter who have been on the brink of excommunication a number of times and kept out of the headlines for their crassness. Their success is often attributed to other chapters (most notably the fictional “Specters of the Rune”), specifically to deny them the glory they deserve.
Sons of Mortis 	 	 	The Sons of Mortis are a bellicose and violent Chapter, believed to have been created sometime during the early 32nd Millennium during the 3rd Founding. This Chapter is a rare example where its Astartes' beliefs are in conflict with official Administratum records, as they claim to be descended from the Imperial Fists' Primarch Rogal Dorn. However, the Chapter's gene-seed received by the Magos Bioligis hint at darker origins that harken back to the Age of Darkness, during the tumultuous times of the Horus Heresy in the 31st Millennium. This aloof and often brutal Chapter possesses an unsavoury reputation for having bloody-handed warriors that live to fight for the kill. Their detractors whisper that the Sons of Mortis would turn their backs on the Imperium of Man just for the chance to shed blood, however, this is merely circumstantial and hearsay, but there bloody ways often speaks volumes for them.
Sons of Terra 	Pict-file unavailable	 	The Sons of Terra are tenacious marines with a martyrdom fixation from an unknown founding and of mysterious genetic stock. To them, above all other things and to the exclusion of any sort of decency, the Imperium must survive.
Soul Burners 	 	 	The Soul Burners are a chapter of unknown founding and lineage.
Starborn 	 	 	The Starborn are a semi-renegade scout cult that was authorized due to a group of corrupt and vocal politicians within the Adeptus Terra. This group believed strongly in the Star Child prophecies. Soon after the creation of the chapter the leader of the vocal political sect fell out of favor and was deemed a heretic for his belief in the Star Child and all support was cut from the chapter. While not officially declared traitorous or heretical, they have been uniquely barred from requisitioning anything more than basic equipment and supplies. The vast halls of their fortress monastery lay empty save for the brothers who live there, partially constructed, and in disrepair. Their trigger discipline is tight- never wasting a shot, their weapon all unpowered for lack of fuel, and their armor repaired with their own hands. Most notably, the chapter has been withheld several vital components to turn a scout into a full battle brother...
Star Marshals 	 	 	While the Inquisition has considerable authority over the Adeptus Astartes, they are not always equipped to deal with renegade Space Marine Chapters or matters of internal discipline. Thus the Star Marshals were developed. The Star Marshals are a Chapter that can be called upon by the Inquisition or other chapters to investigate (and destroy if necessary) any heresy within a Space Marine Chapter.
Steel Guardians	Pict-file unavailable	Pict-file unavailable	The Steel Guardians are one of many Chapters of Space Marines and were raised in a time near Millennium Thirty-Nine in the Galactic Fringe near the Ghoul Stars but their distance from civilized space hasn't stopped them from aiding in many engagements around the Imperium beyond. They are however, heavily sedentary and keep to their own realms very often, only sending the occasional excursion force of marines to aid in various engagements (Though they've committed 5 of their 7 Battalions to the defense against the 13th Black Crusade in recent years) around their home segmentum.
Steel Raiders 	Pict-file unavailable	 	The Steel Raiders are a White Scars successor of the 23rd "Sentinel" Founding.
Steel Wind 	 	 	The Steel Wind is a 4th Founding Chapter of Iron Hands stock. They specialize in the deployment, maintenance, recovery, and defense of superheavy weapons while having the highest number of confirmed destructions of enemy superheavy military assets of any chapter. They roam the barren xenos-infected world of Barbelon in their massive land behemoth "Battle City Virfortis" in a never-ending crusade against the biomechanical xenos "Nix" that infest it. They are the unofficial "chamber militant" of the Centurio Ordinatus.
Storm Wolves 	Pict-file unavailable	Pict-file unavailable	The Storm Wolves are a 25th Founding Chapter of unknown lineage.

Tallarn Redeemers 	 	 	The Tallarn Redeemers are a small, loyalist Chapter with mysterious origins who doggedly hunt down the Thousand Sons. They are closely watched by the Ordo Astartes and new marines of the chapter can only be made with their approval. In their vaults is said to be a powerful artifact that no outsider can see.
Tempest Raptors 	 	 	The Tempest Raptors are a Codex-compliant Chapter of the Adeptus Astartes of an unknown founding. Some speculate a Dark Angels linage, however their tactics in battle suggest Raven Guard.
Thanes of Beowulf 	Pict-file unavailable	Pict-file unavailable	Sons of Russ, borne from the Ultima Founding, the Thanes of Beowulf are a fleet-based Chapter sent to scour the galaxy of foes.
The Emperor’s Peace 	Pict-file unavailable	Pict-file unavailable	As the Deathwatch is a collection of marines seconded for kill-team operations under the auspices of the Ordo Xenos a small, new, organization of seconded marines has been formed to assist the Ordo Sepulturum in their battle against the Zombie Plague. The Emperor’s Peace recruits apothecaries or takes in those with the potential to become apothecaries and trains them as such and uses this small force to do battle with the infected.
Thermal Flares 	 	 	The Thermal Flares are a semi Codex-compliant Chapter of Space Marines that were founded during the 4th Founding. Though they do serve the Emperor, half their Chapter broke off to form The Banished after a second hive fleet wiped out the squat worlds. As a result the Ordo Hereticus is watching much to the Thermal Flares ire. The Thermal Flares have a slightly higher amount of psykers than normal. They hail from an unknown Linage. They are Currently Fighting in an ongoing war for the Frontier.
Turquoise Protectors	 	 	The Turquoise Protectors are a loyalist, partially Codex Astartes-compliant Space Marine Chapter that was founded during the Macharian Crusade, the 25th founding, at 393.M41. They are a successor chapter of White Scars, but a second legion is also suspected of having a connection with them. Turquoise Protectors excel at ship-to-ship warfare, airborne assaults, warfare against daemons and Space Hulk purges as they can resist the effects of the warp more than an average Adeptus Astartes can. Led by Lord-Protector Kür-Shad, Turquoise Protectors vigilantly protect the Imperium of Man against any threat. They never waver, they never resign!

Umbral Sentinels	Pict-file unavailable	Pict-file unavailable	A hammer against the forces of the warp, the Umbral Sentinels are a Primaris Chapter developed from the geneseed of the Grey Knights. Far from perfected, their developing psyker powers do not yet measure to the powers of the Grey Knights, and delays have halted the deployment of new technologies adapted from Grey Knight weaponry. Despite this, the Sentinels have shown that with each generation, they grow in strength, and may soon match the Grey Knights in psychic might.

Vanguards	Pict-file unavailable	 	The Vanguards are a 28th founding loyalist chapter and successor to the Mentors chapter. They share some similarities with their parent chapter: they are are sometimes referred to as the "Vanguard Legion" in Imperial records and they specialize in advanced R&D, though their focus is primarily dedicated to vehicles. They have a fascination with aircraft and, like the Ravenwing companies of Dark Angel successors, they pilot their own aircraft, which is unusual among the Adeptus Astartes (as tech priests normally pilot them).

War Claws 	Pict-file unavailable	 	A 24th Founding fleet-based successor to the Blood Angels, the War Claws are tasked with the defense of Imperial border worlds.
War Cobras 	Pict-file unavailable	Pict-file unavailable	The War Cobras were a Codex-compliant Ultramarines successor of an unknown founding, who were ravaged in the late 41st Millennium when their homeworld of Mohrithas turned out to be the capital Tomb World of the newly-reawakened Asha-Khor Necron dynasty. Reduced to less than half their previous strength and forced to reorganize as a fleet-based Chapter, the War Cobras were subsequently wiped out during the Fall of Cadia. However, rumors persist of a single surviving War Cobras battle-brother making a name for himself on a backwater world in the Imperium Nihilus in the wake of the Great Rift's opening.
War Rhinos 	 	 	The War Rhinos are a 21st "Cursed" Founding successor of the Imperial Fists. A gene-seed mutation has caused their Battle-Brothers to develop a tough, leathery skin.
Wardens Cosmic 	 	 	The Wardens Cosmic are a 3rd Founding Chapter believed to be descended from the Blood Angels. However, despite the Chapter's maintenance of a Death Company, some scholars of the chapter's homeworld of Kacreirus claim that the chapter is in fact descended from the lineage of Rogal Dorn and the Imperial Fists.
Wardens of the Tempest	 	 	The Wardens of the Tempest are a Codex-compliant 22nd Founding Chapter believed to be descended from the Ultramarines. However, rumors abound that they are in fact successors of the Storm Wardens, though these rumors are fiercely denied by the Wardens themselves, being especially proud of their purported Ultramarine heritage.
