Editing Traitor Legion Loyalists (section)

==List of suspected chapters==
It is important to remember here that mere tactical or heraldic similarities are not enough of an indicator for claiming that a Chapter might have geneseed from one of the nine traitor Primarchs. The cultural influence from recruitment worlds combined with millenia of adaptation and evolution can result in Chapters adopting traits that might echo the matrial ways of the ancient Legiones Astartes, without them bearing any relation to them at all.

The telling signs one must be on the lookout for are first and foremost the "historical" ones, that is to say Chapters whose origins trough can be traced back to the first millenia of imperial history trough things like their deeds or their armory, and then everything that might be "genetic".
Because of the genetic link to their Primarchs, geneseed influences the behavior and mindset of a Space Marine. Chapter culture might affect the way in which it is expressed, but it will always manifest to some degree in some way shape or form.
For example, the [[Iron Warriors]] already had a martyr complex before the discovery of [[Perturabo]], as proven by their actions during the siege of Forge World Incaladion.

Without further ado, let's see what we can find, organised by likeliness;

'''All But Confirmed:'''

*'''[[Blood Ravens]]''' The only known copies of their lineage are currently sealed under the orders of the Ordo Malleus:
** ([[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). 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 in incredibly on-the-nose dialogue 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!”
**([[Word Bearers]]) - Speculated, due to operating in Aurelia sub-sector and from the world Cyrene (names associated with the Word Bearers, and an area originally controlled by the Word Bearers during the Great Crusade), as well as a fanatical search for Knowledge (However this is also a trait of the Thousand Sons). Their warcry "Knowledge is power, guard it well", is a direct quote from the Word Bearer First Chaplain [[Erebus]] (However this was also a common saying of the Thousand Sons and spoken by the Thousand Sons Revuel Arvida). However, the Thousand Sons connection is so obvious that this connection is a long shot at best.
*'''[[Minotaurs]]''':
**(Old Lore) ([[World Eaters]]) - Speculated. Similar battle doctrine, known for being complete berzerkers in battle. However this maybe due to their chimeric geneseed just making them batshit insane.
**(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' anatolian/eastern-byzantine/ottoman references, 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. Horus Heresy Book 6 "Retirbution" also alludes to the Iron Warriors being the progeniotors of the Minotaurs, as there is described a special unit of Iron Warriors who use heavy hypnoindoctrination and specialized in Counter-Astartes tactics. Edwin Brown, a playtester for the [[Badab War]] books, has also stated that the Minotaurs use Iron Warriors gene-seed.
**Of note: the "new" lore alludes to the possibility of there having been two Chapters called the "Minotaurs", with one being more similar to the old lore descriptions, being part of the [[21st Founding|21st Cursed Founding]] of M36, and references to chimeric gene-seed. Presumably, the old lore Chapter had chimeric World Eater/someone else (possibly Iron Warriors) geneseed and their creation/extinction was to secretly legitimize the "original" Iron Warrior Minotaurs under the direct command of the [[High Lords of Terra]]. Or the Imperium's shitty record keeping, combined with the (Iron Warriors) Minotaur chapter being so clandestine, lead to a completely unrelated chapter getting the name "Minotaurs" without knowledge of the name having already been taken.
*'''[[Shadow Wolves]]''' ([[Luna Wolves]]) - Confirmed by creator, but in-canon explanations currently lacking. Despite not being Space Wolves successors (being listed as Imperial Fists), they use tons of Wolfish iconography [[Bjorn the Fell Handed#Stormfangs|(no, not '''that''' kind)]]. Author/creator of the chapter ([[Aaron Dembski-Bowden]]) 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).
*'''[[Silver Skulls]]''' ([[Iron Warriors]]) - All but confirmed. 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", a rank that had only seen use with the Iron Warriors), 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. The author of the Silver Skulls series has said they are successors founded from Dantioch's garrison, and were adopted by the Ultramarines (thus making them a case of the ''Ultramarines Connection''). She has also said that their religious aspects are 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.
*'''[[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.

'''Extremely Likely:'''

*'''[[Marines Malevolent]]''' ([[Iron Warriors]]) - Speculated. 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. Lastly, but most noteable, their emblem (a winged lightning bolt) was the original emblem used by the IVth Legion, before reuniting with Perturabo.
*'''[[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. 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 [[Primarch|taller than usual for an Astartes]], [[Alpharius|conceals his face]], and has been known to [[Omegon|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''.

'''Likely:'''

*'''[[Sons of the Phoenix]]''' ([[Emperor's Children]]) - Suspected. It's an open secret that [[Belisarius Cawl|Papa Cawl]] got a hold of uncorrupted III Legion gene-seed). They have similar iconography to the 3rd legion, and their name also possibly references Fulgrim, who was known as the Palatine Phoenix. Known for liking to put on a show when in combat. That being said, the creator of the chapter (Maxime Pastourel) stated that he intended them to be Imperial Fists successors and that the choice of colors was meant to give them an 'ecclesiarchical'. This could be a rare case where the obvious ressemblance is purely coincidental.
*'''[[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.
*'''[[Mantis Warriors]]''' ([[Alpha Legion]]) - Speculative, officially from [[White Scars]] stock. Like the Alpha Legion they operated from a series of hidden bases spread across the sector of space they were guarding rather than having a single HQ. In-setting they're suspected to be descended from the White Scars, but the source making that claim is a in-setting book written M36 by a High Lord of Terra that has been edited multiple times since then by other High Lords and multiple Inquisitors. Their tactics are more reminicent of the Alpha Legion than the White Scars, with a focus on stealth, ambushes and the like. Their colours (green and yellow) match the Rogue Trader-era AL paintjob, and FW's book mention that the Alpha Legion have been seen fighting in green power armour. They maintain elite cadres of skilled marksmen who assassinate enemy leaders, rather like the 30K-era Headhunter Killteams of the Alpha Legion. Not to mention, the Alpha Legion fought the White Scars multiple times across the Heresy and FW's version of the [[Chondax]] campaign has several hundred White Scars on recon missions "disappear mysteriously". Finally, an alternative name for the Mantis Warriors is the "Mantis Legion".

'''Other Possiblities:'''

*'''[[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 Pre-Primarch era Thousand Sons.
*'''[[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 [[Black Templars|The Howling]], and the 4th [[Black Crusade]]. 
*'''[[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) (or maybe just like most Ultramarines successors). Records of their origins have been "deliberately" lost or destroyed (like the Lost Legions'). Additionally their homeworld is sanctioned against contacting the rest of the Imperium (not simply purged like a Chaos hive would have been) and is basically sealed off from the outside world. Though they are frankly more likely to be Iron Hands (the previous token "Scottish chapter"; also previously named "Storm Walkers") successors due to their "special friendship" with the AdMech and fondness for hiding inside metal bawxes. Or, like, possibly ultramarines like basically any other blue boys who use standard marine battle tactics of mechanized infantry, but they may just be the "Ultramarine Connection" counterpart to the Emperor's Spears' actual celtic sons of Guilliman.
*'''[[Fire Angels]]''' ([[Word Bearers]]) - Speculated. Highly similar behaviors and doctrine. Strict following of whatever rules they are given? Check. Do they follow the Codex to the letter? Check. Highly religious? Double check. Don't like Guilliman? You can bet that's a check. The combination of all of these traits makes them essentially loyalist Word Bearers in all but name... but that's as far as the similarities go. 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 above). 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, much like the Minotaurs, there are noted records hinting that [[Sable Swords|theirs is not the first incarnation]] of the Fire Angels Chapter.
*'''[[Covenant of Fire]]''' ([[Word Bearers]]) - Speculated. While officially listed as "Salamanders", the Covenant of Fire could be Word Bearers who follow the Promethean Cult instead of worshiping the Emperor or Chaos. Their iconography is very similar to the pre-Heresy XVII Legion, and their attitudes and behaviors are also extremely similar to the Word Bearers, most specifically their "Ashen Circle" units. Seems Cawl could have run out of fucks to give and is now just seeing how far he can push it before Guilliman catches on.
*'''[[Sons of Antaeus]]''' ([[Death Guard]]) - Speculated. Similar genetic traits included an unnatural hardy stock.
*'''[[Death Spectres]]''' ([[Death Guard]]) - Speculated. Similar name, as well as similar iconography to the pre-heresy Death Guard. Their homeworld of "Occuludas" is also the last known location of Crysos Morturg, a loyalist member of the Death Guard, as well as his "108th Independent Company". They also prefer using Power Scythes in combat, a preferred weapon of the Death Guard. Like the 108th Independent Company, the Death Spectres have been tasked with protecting the Imperium from threats originating from the nearby Ghoul Stars. There is a lesser known background book that makes them out to be Raven Guard, but much of the book has been ignored, contradicted, or outright retconned since then, so it's likely their chapter origins have been too.
*'''[[Shadow Haunters]]''' ([[Night Lords]]) - Speculated. While they are listed as Raven Guard from the 19th Founding, their name harkens back to the title taken by the Primarch of the Night Lords: Night Haunter. They specialize in terror tactics and they suffer from a geneflaw which causes them to have horrific visions, similar to the geneflaw suffered by the Night Lords. Granted, this information comes from the chapter's creator's self-made Index, and not from an officially published source.


'''Special Cases:'''

*'''[[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]]''' (Official Imperial Fist successors. Classified and speculated Successors of the [[Grey Knights]] in old lore...alternatively [[Word Bearers]]) - The link to the Grey Knights is iffy since only due to a small mention by an Inquisitor, and the Grey Knights are notoriously against ANYONE messing with their gene-seed. However, the Exorcists colors, scripture written on their armour, and nature as anti-[[demon]] specialists is almost 1 to 1 with Heresy-era [[Word Bearers]]. It is not completely impossible since they are from the [[13th Founding|Dark Founding]].
*'''[[Carcharodons]]''' (Traitor [[Raven Guard]]/[[Night Lords]]/[[World Eaters]]) - Speculated. Physical traits (black eyes, pale skin) similar to both Raven Guard and Night Lords. A gene scan of a dead Carcharadon revealed markers for Raven Guard. They also suffer a Battle Rage they called "The Blindness" which manifests exactly like the Raven Guard's "Ash Blindness". They often have a black and white morality, focus on shock and fear tactics combined with stealth, and their 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. Likewise, a Night Lord officer noted that the Carcharodons seems to be a mirror of their own legion, which the original XIXth legion were known to have been. These further indicate they are both of the XIXth Legion, specifically the Terran born XIXth Legion under the command of their original legion commander: Shade Lord "Arkhas Fal", as the Carcharodons share the title for their leader: "Shade Lord". Notably, the Ashen Claws (a nominally loyalist renegade warband form of a different group of Terran-born XIXth Legion who had been exiled by Corax before the Heresy) have flatly called the Carcharodons "traitor-born", as it was most likely Arkhas Fal's Predation Fleet that joined Horus's side in the war. At the very least, it was likely the Carcharadons are who joined Horus, as he gave them the name "Pale Nomads", a title now used by the chief librarian of the Carcharadons. Of course, there’s also the possibility that they could have a chimera geneseed…which may not have been chimeric originally.
*'''[[Ashen Claws]]''' (Night Lords/Renegade Raven Guard) - Note: While technically not an officially listed chapter, they have recently begun to fight for the Imperium again. Similar to the Carcharadons, they were founded by an exiled predation fleet of the Raven Guard. This time, the fleet lead by Shade Captain Nerat Kirine, the fleet exiled after the Battle of Gate-42. During the heresy, the fleet returned and declared they fought for neither Horus nor the Emperor. Instead they fought for themselves. They raided the Nostromo Sector, looting war gear as well as stealing the geneseed from the Night Lords they slew.
*'''[[Angry Marines]]''' ([[World Eaters]]) - They can say whatever they want about [[Rachnus Rageous|who they think their Primarch is]], but the Inquisition still suspects [[Angron]].
