COMPLETELY 100% LOYAL.

"Thou shalt not follow a multitude to do evil."

– Exodus 23:2

Traitor Legion Loyalists are the rare few Space Marines who, despite hailing from the Traitor Legions, stayed loyal to the Emperor and the Imperium, proving that despite what some characters in 40K think, having geneseed from a suspect source is no sure indicator of bad character. They are a very rare group of individuals given the initial purges of Loyalists elements from the Traitor Legions at the Battle of Isstvan III or by internal purges such as those enacted by “The Brotherhood” in the Word Bearers. While most of the information below has just been hints for now, this is a matter that has been popping up every now and for the last few years.

As it happens, many of these Traitor Legion Loyalists during the Horus Heresy who did not end up in the annals of history became Blackshields, the precursor to the 40K equivalent of the same name where a Marine with no emblems or markings can petition to join with the Deathwatch on a permanent basis, no questions asked. The term "Blackshield" by itself leaves it open as to whether the individual Marine seeks to redeem himself OR his chapter if it went rogue or was destroyed. Although Blackshields are a rarity in 40K, there were enough in 30K for such a tradition to begin and survive to the present day in the Imperium.

Those groups with enough numbers, or perhaps ties to the right people, were able to pass themselves off as successors of other Chapters after the Second Founding. Or their founders purged and changed their own records, so that over time, no one within the Chapter knows who their true progenitor is (which can lead to some fun times when an Inquisitor comes across evidence that it occurred).

Generic armies of them can be fielded in 30K with the Orphans of Betrayal Rite of War. As is fitting for a rogue, largely unsupported force, the rite doesn't provide many bonuses unless you're fighting Traitor versions of the same Legion you're fielding.

After reuniting and resurrecting his body, he learned that the attack on Prospero had been ordered by the traitorous Warmaster Horus Lupercal and not the Emperor of Mankind. He later closed the warp gate to the maze in order to prevent Magnus the Red from following the Space Wolves).

  • Occam the Untrue (Leader of the REDACTED warband. Considers his legion a tool to test the Imperium. Currently interrogating a Deceiver shard bound in a Tesseract Labyrinth after a very costly battle in M42)

List of suspected chapters

• Grey Knights (Founders were initially drawn from the Knights-Errant) - Outright stated, although only from their history. While several Astartes from Traitor Legions were among the founders of the Grey Knights, the Grey Knights believe their gene-seed is derived from the prime template of the Emperor, though whether that's true is a point of contention among the fanbase (despite it being repeatedly and clearly stated in any and all Grey Knight's fluff, it's still unclear just HOW Big E made it).
• Exorcists (Successors of the Grey Knights...alternatively Word Bearers) - Confirmed by extension from the Grey Knights. Alternatively, the link to the Grey Knights is only due to a small mention by an Inquisitor....and the Grey Knights are notoriously against ANYONE messing with their gene-seed. However, their Chapter colors, scripture written on their armour, specializing in getting possessed by daemons (the Exorcists then banish the daemons from their bodies) are almost 1 to 1 with Heresy-era Word Bearers.
• Shadow Wolves (Luna Wolves) - All but confirmed. Despite not being Space Wolves successors (being listed as Imperial Fists), they use tons of Wolfish iconography. Author/creator of the chapter (ADB) confirms they were created to represent the concept of loyalist Luna Wolves as a tribute to his wife Katie (who is a fan of the Luna Wolves).
• Blood Ravens (Thousand Sons) - All but confirmed. Links to the Thousand Sons Corvidae Cult, high number and heavy usage of Librarians (especially to look into the future to scry enemy's plans like the Corvidae Cult), similar color scheme to Pre-Heresy Thousand Sons, similarly have an extreme thirst for knowledge. The only known copies of their lineage are currently sealed under the orders of the Ordo Malleus. Just prior to the Fall of Prospero, a psyker named Kallista Eris foresaw the future of the Thousand Sons Corvidae Cult, during which she all but states they will become the Blood Ravens: "The Ravens. I see them too. The lost sons and a Raven of Blood. They cry out for salvation and knowledge, but it is denied!”
• Brotherhood of a Thousand (Thousand Sons) - Speculated. Minor Chapter with a tiny footnote implying heavy librarius and have a similar name. Use an "M" as their Chapter symbol, similarly to the heraldry of the Great Crusade-era Thousand Sons.
• Minotaurs:
  • (Old Lore) (World Eaters) - Speculated. Similar battle doctrine, known for being complete berzerkers in battle.
  • (Revamped Lore) (Iron Warriors) - All but confirmed. They maintain a similar battle doctrine that favours close combat but is now also focused on pragmatic, siege, and attrition warfare tactics (their special rule is a near exact match for the Horus Heresy Iron Warrior's signature special rules). Their Ancient Greek theme also matches up with the Iron Warriors, and their gene-seed is mentioned to have extremely high assimilation rates, just like the IVth Legion of old. They even have records of action dating back to M32. Edwin Brown, a playtester for the Badab War books, has also stated that the Minotaurs use Iron Warrior gene-seed. Of note: the lore alludes to the possibility of there having been another Chapter called the "Minotaurs" more similar to the old lore descriptions, being part of the 21st Cursed Founding of M36, and references to chimeric gene-seed, adding to the the confusion of it all. Presumably, the OG Chapter had chimeric World Eater/someone else geneseed and their extinction was hushed up to secretly refound them as Iron Warriors under the direct command of the High Lords of Terra. One of the Badab War writers said that they were loyalist Iron Warriors rediscovered during the Great Scouring in a distant garrison who hadn't received the news of the Heresy AT ALL, somehow. They were allowed to remain under a short leash by the High Lords. Again presumably, the Cursed Founding World Eater/someone else chimera Minotaurs being destroyed in a sufficiently deniable fashion allowed the High Lords to get this secret unit formalised.
• Marines Malevolent (Iron Warriors) - Speculated. Very similar behaviors to Iron Warriors, some similar iconography. Extremely pragmatic, consider one another disposable, complete disregard for causalities or collateral damage, an extreme disdain for weakness, a tendency to challenge other Chapters, and they are pretty entitled little bastards. Like the Minotaurs, they take the wargear of defeated Astartes foes as trophies. They basically are the Minotaurs, if the Minotaurs DIDN'T have the backing of the High Lords. Their veteran's markings are also identical to the Iron Warrior's signature yellow/black hazard stripes.
• Silver Skulls (Iron Warriors) - Speculated. Suspected to be from the gene-seed of the loyalist Iron Warriors, led by Barabas Dantioch, who helped defend Ultramar. The Silver Skulls are well known for siege warfare (including a rank called "Siege Captain"), masters of building fortifications (their fortress monastery is said to have impressed Rogal Dorn himself), and their Chapter iconography/colors are near identical to pre-Heresy Iron Warriors. Their Chapter records are stated as "lost" so they do not officially know which legion they are founded from, despite being Second Founding. Their gene-seed records on Terra are also locked away beyond even Inquisitional authority. It's not that clear though, as they also act a lot like the Word Bearers. The Silver Skulls worship the Emperor as a god (rare for Astartes but not unheard of), and more tellingly they have absolute faith in the Emperor's Tarot and will religiously follow the word of prognosticators (making battle plans and combat decisions based entirely on these). The writers have said this is just due to the culture they are recruited from, and Silver Skulls from outside their main recruitment world find these traditions strange and backwards as well, making the case less clear. Due to being Second Founding, they are also possibly an example of the Ultramarines Connection.
• Necropolis Hawks (Iron Warriors) - Speculated, officially listed as Raven Guard successors. Similar behaviors to the Iron Warriors, particularly pragmatic, calculating, unrelenting, brutal, and a preference for close quarters combat. Unlike most supposed Raven Guard successors, they do not specialize in stealth, ambush, or guerrilla tactics (or really use them at all). Instead they specialize in urban warfare/city assault (as in siege warfare, once the walls are breached). tl;dr - They act nothing like their supposed progenitors, but a LOT like Iron Warriors. Not like Cawl hasn't made other Primaris chapters from Traitor Legion gene stocks.
• Death Eagles (Emperor's Children) - All but confirmed (origin suspected due to records of a Loyalist Blackshield warband from the Emperor's Children's Death Eagles company during the Horus Heresy) while the Chapter's recorded actions stretch back as far as M32.
• Red Scorpions (Emperor's Children) - Speculated. Have an obsession with the "perfection" of their gene-seed, to the point of being outright hostile to any they see as "imperfect". Said geneseed also happens to have a mutation rate inferior to even that of the Ultramarines and Dark Angels (purest among the loyalist legions), but the Scorpions refuse to surrender any samples to the Inquisition. There is also the fact that their armories are stacked with old-patterns of tech, such as Deimos-pattern predators, Proteus-pattern Land Raiders, and MKIV dreadnoughts; which unlike the Minotaurs, cannot be explained by High Lords favoritism. Unlike the Death Eagles or Carcharadons though, there are no records of them existing as a Blackshield force during the Heresy. The Chapter only enters Imperial records for the first time until M34, well after The Howling, and the 4th Black Crusade.
• Sons of the Phoenix (Emperor's Children) - All but confirmed (it's practically confirmed that Papa Cawl got a hold of uncorrupted III Legion gene-seed). Similar iconography. Their name also possibly references Fulgrim, who was known as the Palatine Phoenix. Known for liking to put on a show when in combat. Causing as much flash and boom as they can, like a rock star concert. The even have groupies.
• Carcharadons (Night Lords) - Speculated. Possible chimeric gene-seed. Most similar beliefs and battle doctrine to Night Lords. Often have a black and white morality. Focus on shock and fear tactics combined with stealth. Preferred tactic is to brutally and horrifically annihilate the target population (be they enemy or civilian), but leave a few survivors to go tell everyone else about what happened. Physical traits (black eyes, pale skin) similar to both Night Lords and Raven Guard. Dagger-like teeth similar to Kurze's own. Mental mutations and unstable sanity similar to Night Lords. Similarly to Night Lords, the Charcaradons recruit from criminal populations. Their newest lore hints at them being at least one part Raven Guard successors; specifically the Ashen Claws: a blackshield warband that was heavily involved in the fights across the Nostramo sector during the Heresy, as the Carcharadons share the title for their leader: "Shade Lord". However, the Ashen Claws warband still exists as of M41. Notably, said Ashen Claws have called the Charcaradons "mongrels" aka "mixed breeds", hinting at either Chimeric gene-seed, or possibly that the Carcharadons use both Raven Guard and Night Lords gene-seed lines in parallel.
• Raptors (Chapter) (Night Lords) - Speculated, only rumored to be Raven Guard. Gene-seed more similar to Night Lords. While they suffer the pale skin/black eyes seen in both Raven Guard and Night Lords, unlike the Raven Guard but just like the Night Lords, they have fully functional Betcher's Glands. Their homeworld is near the Eye of Terror, but despite being a well known and active Chapter, their homeworld's name has been "lost", so no one knows what or where it is. The Chapter once blockaded a system, with the entire system's population vanishing. Anyone who attempted to investigate, even members of the Inquisition, also disappeared without a trace. While the Chapter shares it's name with Corvus Corax's attempt at making a Space Marine 2.0, said attempt ended in complete failure thanks to Alpha Legion sabotage, the mutated products of the program were all killed in battle.
• Storm Wardens (World Eaters) - Speculated. Similar preferred battle doctrine and color scheme to pre-Heresy War Hounds (armored assaults combined with close-combat infantry, blue armor with white pauldrons). Records of their origins have been deliberately lost or destroyed. Additionally their homeworld is sanctioned against contacting the rest of the Imperium.
• Executioners & Successors (World Eaters) - Speculated. Similar battle doctrine. Highly similar Chapter culture and behaviors. Iconography made of images minorly associated with the World Eaters (red, axes). Two of their three successor Chapters' names invoke more Khornite associations (Crimson Axes and Skull Bearers). Known for having some of the most brutal close combat methods, even for Astartes. A liking for decorating their armour with the flayed skin of their victims. Lineage questioned by other Imperial Fists successors due to lacking traits associated with the sons of Dorn. Known to be reclusive, only closely associating with their own successor Chapters. This isn't exactly unique among Imperial Fist successors however, and the HH black books and novels all but state that their unique culture is due to their origins in the VIIth legion's specialist formations.
• Fire Angels (Word Bearers) - Speculated. Highly similar behaviors and doctrine. Strict following of whatever rules they are given? Check, they follow the Codex to the letter. Highly Religious? Double check, they make the Black Templars seem like choir boys in their levels of religious zeal. Don't like Guilliman? Check. Their armour colors are even the same as the Word Bearers, just reversed (what the Word Bearers paint red, the Fire Angels paint silver. What the Word Bearers paint silver, they paint red). The combination of all of these traits, along with their Chapter colors) makes them essentially loyalist Word Bearers in all but name, but that's as far as the similarities go. One must not forget they aren't the only highly religious Astartes Chapter, nor are they the only Chapter to adhere so strictly to the Codex (especially among Ultramarines), or the only "Ultramarines" successors to not like Guilliman (see the Mortifactors below). Much like the Executioners, there isn't any evidence hinting that their behavior is the result of genetics and not the cultural changes undergone by the Imperium in 10 000 years, especially considering that they are a Chapter that wasn't founded until very recently. However, there are noted records hinting that theirs is not the first incarnation of the Fire Angels Chapter.
• Sons of Antaeus (Death Guard) - Speculated. Similar genetic traits included an unnatural hardy stock.
• Mortifactors (Death Guard) - Speculated. Similar color scheme and iconography to pre-Heresy Death Guard, specialize in night fighting like the Dusk Raiders, similar grim attitude, and have a preference for using Power Scythes (the signature weapon of the Death Guard). This Chapter is also obsessed with death, I mean really obsessed with it. Like the Fire Angels, these guys really do not like their "official" Primarch. Being a Second Founding Chapter, they could be a prime example of the Ultramarine Connection.
• Iron Snakes (Alpha Legion) - Speculated, officially from Ultramarine stock. Use combat doctrines and show behaviors extremely similar to the Alpha Legion. Similar iconography (a single-headed snake instead of a three-headed hydra). The Iron Snakes also have unusually specific design similarities to said Alpha Legion. Such as their Chapter Master being taller than usual for an Astartes, conceals his face, and has been known to swap identities. They also separate their Chapter into independent cells, just like Alpha Legion harrows. Due to being Second Founding, they are also likely an example of the Ultramarines Connection.

The Ultramarine's Second Founding Connection

The Ultramarines are confirmed to have harboured loyalist members of Traitor Legions after the Heresy, rebranding them as their own to obfuscate the newcomer's past (as for why they would do such a thing, Roboute Guilliman himself is characterized as someone who abhorred the waste of any human life (Astartes or otherwise). Guilliman also needed all the manpower he could get when he thought the rest of the Imperium was destroyed during the era of Imperium Secundus, so giving even legionnaires from suspect sources a chance to prove themselves was a practical solution, for which in the end he was not disappointed. The penning of the Codex Astartes and the shattering of the Legions into individual Chapters would also have provided the perfect opportunity to separate the loyalist Traitor Legion elements back into separate formations (both to work more as they were intended, and to make it easier to exterminate any of them that decided to betray the Imperium at a later time). Furthermore, it is confirmed that after [REDACTED] that led to the deaths of the Missing Primarchs happened, the Astartes of the II and XI Legions were mind-wiped by Malcador the Sigilite into thinking they had always been part of the Ultramarines and Imperial Fists, as to not waste useful Astartes assets. This act was backed up by Dorn and Guilliman voluntarily agreeing to have their memories of what really happened suppressed beyond even a Primarch's ability to recall. Dorn would later have this mental block partially lifted, making it likely Guilliman did the same.

Of the Chapters listed above, the Chapters that are suspected of this connection are:

• Silver Skulls - Iron Warriors
• Mortifactors - Death Guard
• Iron Snakes - Alpha Legion
