The Gene-Seed Of The Lost Legions - 40K Theories

Prior to the onset of the Horus Heresy, the second and eleventh legions of the Legiones Astartes would be erased from history, with all records regarding their names, deeds and Primarchs being expunged from Imperial Records. But just what exactly happened to the gene-seed stocks of the two Lost Legions?

''The primarchs were designed to be far more cognitively sound than other humans'' that went well

[@zenoblues7787]

Ignoring Obvious Examples like Angron and Konrad I point to the petulance of Perturabo who could never let of a grudge no matter how minor and stubbornly refused to change battle tactics in spite of their obvious shortcomings. Their's also the clear example of Lorgar who seems to be both a lost soul seeking guidance and a sociopath who wants to justify his horrible actions. This is pretty clear proof that at least some Primarchs were never cognitively sound at all.

[@40KTheories]

You could argue about nature vs nurture in this case. Perturabo was an artistic savant and an engineering genius, regardless of his petulance. Lorgar's psychological instabilities stem from the fact that he was heavily abused by Kor-Pharon as a child, regularly scolded and beaten, even when Lorgar wanted to make his "father" proud by showing him he could read.

[@mattroxursoul]

I always took the Black Templars to be like an inversion of the Fists more calm and rational behavior and deployment. Or just Sigismund. As far as the gene seed it is anyones guess. Imagine Malcador could have planned for that by putting those soldiers together in certain spots where they would not be reclaimed. Sure it is possible that the seed is in use now. How much do we really know about Gene seed stuff though? How it is gathered, how it is stored and how is it checked.

[@valandil988]

Yeah I would put malcador's over the top reaction to speaking the lost primarchs name to oneside. The geneseed is so poorly understood anyway that I doubt they could recognise the difference between stocks unless specifically looking. So I doubt they replaced it.

As Cawl stated in Dark Imperium, "The warriors were not at fault, the science was not at fault, the Primarchs were". I think the gene seed of the lost and the purged, was preserved. Also, as far as the Thousand Sons goes, remember, Revuel Arvida had his gene seed purified by the soul shard of Magnus. This act could have given the Emperor the ability to create stable thousand sons successors, i.e. the blood ravens.

[@40KTheories]

And yet long after Janus' geneseed had been purified and the Grey Knights were sent to Titan, the Emperor still claimed that the Flesh Change was incapable of being expunged. (Side note, if the Blood Ravens were Thousand Sons successors, then given the events that happened in Ashes of Prospero, they would have all succumbed to the Rubric. But while the geneseed of the Thousand Sons awakens the psychic potential of those that have it, there is *no* such genetic trait found in Blood Raven geneseed. Their index astartes articles even state outright that the reason for them having such a high number of psykers is _not_ genetic)

I think what happened to the 2 lost primarchs was simple, they landed on a xenos world, and were inducted into the respective xenos race. Perhaps they rose to conquer and lead their xenos race, or the xenos race indoctrinated and used them as a tool like the Emperor intended to do so himself. A primarch that fights for a non-human race, would support that first quote you dropped from Malcador - it would have threatened everything the Great Crusade stood for.

Perhaps the Thousand Sons gene-seed wasn't actually that corrupted, perhaps the cause of the Thousand Sons catastrophic rate of mutation wasn't the gene-seed itself but a side effect of it being based on Magnus who was most closely attuned to the warp and all the subsequent work done on it was infact an attempt to use the gene-seed to counteract this effect.

An Avatar of Humanity, fighting for the future, trying desperately to stave off extinction; and sometimes drastic measures are necessary. That is the way I picture the Emperor. His end goal is noble, but the path he is forced to walk often dips into the shadow.

[@mistsofthenexus76]

Actually, a bit of a correction regarding TS gene-seed and purging of it's deficiency @40k Theories. SPOILERS FROM FURY OF MAGNUS Alright, so when Magnus infiltrated the Golden Throne, and the Emperor spoke to him, he used the promise of a new legion to be of use to Magnus from his (Magnus) own gene-seed, but purified. Seeing how this legion could be nothing more than the nascent Grey Knights, that in itself confirms that with the possibility that the TS geneseed was being used to create them (with what I suspect, a combination of the Emperor's own genome to stabilise it), Magnus geneseed was actually stable (as the current Grey Knights are incorruptible). By that logic, what if this process was kept recorded to this current age, meaning that the actual genome (with the emperor's input) of the Thousand Sons is actually stable. The other possibility of stability he meant was purity - if we were to argue semantics, the statement that Knowledge is inherently neither good nor bad, that exact same logic can be applied to the gene-seed being akin to knowledge - neither good, nor bad.

[@40KTheories]

The Emperor states to Magnus: “But I will build you a new Legion, a mighty host of warriors greater than any now living. Plans are already in motion to bring about their inception. Soon, you will command warriors the likes of which the galaxy has never seen, whose flesh will be flawless, whose fists are steel and whose hearts are armoured in adamantium!” While it is indeed likely that this is regards to the Grey Knights, the Grey Knights are repeatedly stated to have their geneseed derived directly from the Emperor's own genetic material (as shown with the Pandorax passage in this video). This particular stock of geneseed is even implied to be the same source used to create the proto-astartes such as Leetu, whose geneseed was derived from the Emperor and Erda prior to the creation of the Primarchs themselves (as shown in Saturnine). As such, it seems to me that Magnus would have been appointed to serve as the commander of the Grey Knight "legion" as opposed to being their father. In this way he'd be more reminiscent of a Thunder Warrior Primarch. Also, in Fury of Magnus, the Emperor states to Magnus when offering him a new legion: "Your mind and body are still your own, but the warriors of your Legion are damned. In truth, they were damned the moment the first signs of the flesh change became manifest. Their bodies carry the seeds of their own destruction, and no gene-craft of mine nor the Selenar can undo it. You can come back to me, but your Legion cannot." If the Flesh Change (which first began manifesting within the first 5-10 years of the Great Crusade) could be undone by using fresh supplies of DNA drawn from Magnus himself, similar to how the Emperor's Children cured themselves of the Blight; by drawing fresh genetic stock directly from Fulgrim himself after reuniting with him, then surely they would have attempted to do so? Don't get me wrong, I understand your viewpoint and where you're coming from, but given the Emperor's words to Magnus and the comparisons with the Blight, I don't see how the geneseed of the Thousand Sons themselves could be stabilised in any way when neither the Emperor nor the Selenar could perform such a feat. (Assuming that the Emperor isn't lying, but we have no way of knowing if he is in that particular regard)

Which would raise the question, what would the other have done that would have been on par with falling into the worship of the god of anarchy. Considering the type of god malice seems to be, I highly doubt that the primarch who fell would try to corrupt his brother, instead of merely trying to kill them. Its possible however.

Its an interesting thing about the geneseed of the Thousand Sons, in A Thousand Sons when Tzeentch speaks to Magnus, he very much hint if not outright state that the flesh change is his doing. That could imply that the flesh change of the Thousand Sons was not genetic in nature, but more so so warp based in nature, sort of in the same like the plague of nurgle. You can´t cure it no matter how much penicillin you drink, because its not caused by a normal virus or bacteria. That would explain why the Cawl inferior didn´t find any flaws in the geneseed of the thousand sons, because the flaw wasn´t genetic. It would further imply that IF the flesh change was warp induced that Tzeentch for lack of better word hacked into the Geneseed of the Thousand sons, if you could theoretically install a "firewall" maybe through chimeric measures, the geneseed would become stable and keep Tzxeentch out.

[@jackrogers5712]

I don't see the problem with some successors diverging significantly from their founder. The Black Templars are frequently thought to be actual sons of Dorn, but I don't see there being a problem. In the same way as the Primarchs all took after aspects of the Emperor's personality, so too do Space Marines take after aspects of their Primarchs. Sure, Sigismund wasn't at all similar to the majority of other Imperial Fists. Nassir Amit wasn't overly similar to most other Blood Angels either, but he was a Son of Sanguinius regardless. Most Blood Angels took on Sanguinius' nobility, beauty and grace but Amit and his ilk took after Sanguinius' rage that he usually kept hidden. When the Legions were divided, it only made sense to group Marines that had similar personalities together. The fair and noble Blood Angels stayed with the original name, the brutal guys went on to become Flesh Tearers and so on. This works the same way with the Fists - the stubborn and patient stayed Imperial Fists, the zealous became Black Templars, the headstrong and youthful Crimson Fists and so on.

[@andrewgranger3370]

Had one of those late-night epiphanies and had to come back and rewatch this video so stay with me here. The official reason given for the lost primarchs and legions had to due with the lost legions of the Roman Empire, the designers liked the idea of lost legions and put it into the game. They also threw out the idea that it gave players a chance to play "thier guys" i.e. home brewed marines without having to stick to the established chapters. Now that was a long time ago, and the lore has changed quite a bit, but the official word is we will never learn who the lost primarchs were. BUT, we have been told the Legions were folded into the Ultramarines and the Imperial Fists. While the replacing of the Genenseed is a possibility, that is a TON of Geneseed to replace even from stable stocks like the Ultramarines and the Imperial Fists. Now suppising Dorn and Guilliman did not use these guys as canon fodder, and they did not have their Geneseed replaced, you have to imagine that those casualties had their progenoids removed when possible and used to create more marines, especially in the case of the Fists who did a LOT of fighting during the Heresy and the immediate aftermath. Both Legions were apparently still large enough to be broken up into several chapters in the first founding. It stands to reason that some of these chapters were built, at least in part with marines from the 2nd and 11th Legions. Now a lot of people make their own Chapters and I would hazard to guess that outside of the two Angels Legions, the Fists and the Ultramarines are probably the two most popular Legions to take a successor from. Maybe, and this could be a stretch given GW's hit-and-miss fan friendliness, but it could be, having the lore state that the 2nd and 11th were folded into the Imperial Fists and Ultramarines was a way to leave that door open for players to play "their guys" and have them be from the lost legions. Seriously, given the loses of the Horus Heresy it seems illogical that the Geneseed of those marines who were given this sceond chance would be thrown out.

I've always wondered if, because the Emperor knew Magnus far before he knew any other Primarch, during his psychic conversations with Magnus he realized his ambitions and curiosities and decided to engineer a "backdoor" into their genetic makeup in case they got too curious (which they did). It's one thing to have 1,000 Thousand Sons going against Dorn. It's another thing entirely if there are 30-40,000 Thousand Sons as traitors. Yeah, I know the Sons probably wouldn't have betrayed the Emperor if Horus hadn't ordered Russ in, but there's always that chance and the Sons were just too much of a wildcard. Maybe I'm off or missed something, I dunno.

I have a theory that while the gene seed may've been taken and replaced, the material from the original source of the warrior would've mixed with the new gene seed to make a new stock. I read somewhere that the material of some successor chapters have mixed somehow with the material from other unknown chapter sources. They couldn't completely get rid of the material from the lost legions so they just classified it as a genetic deviation to keep people from looking too closely.

His non-blank genesons joined the legions of Dorn and Guillemon as there was no dishonour, only the need to protect the Imperium as it required psykers to function. But he's still out there, circling the galactic edge and trying to fight off Tyranid fleets and crushing enemies of Humanity before they attack the Imperium.

Its best to be a little careful when discussing the Cawl Inferior. Since in the Cawl novel, Cawl has stated he doesn't want to be Fabricator-General of Mars. He says he knows for a fact it would cause a civil war, besides becoming Fabricator-General would limit him and make him an administrator rather than the freedom of being a Grand Magos. Cawl says the next time he meets Guilliman in person, he will examine the Inferior to find out why it is saying these things. But if you listen to the entire conversation, the last thing the Inferior says before he asks Guilliman to make Cawl leader of Mars and use all the Primarch's gene seed is, 'Security Protocols enabled.' I suspect that Cawl Inferior has created its own security program when dealing with Guilliman. It repeats the same arguments and listens to Guilliman's responses. If Guilliman agrees or his arguments are poor (very unlike him). Then the Inferior would immediately alert Cawl of a problem with the Primarch. As how the EoM would allow the gene-seed to remain in the now brain washed surviving 2nd and 11th Astartes? Well the Horus Hersey happened very shortly after the two were lost and forgotten. The EoM and Malcador also didn't plan on dying at the end of the Hersey. So any plans to keep 2nd and 11th gene seed out, never happened.

Something to keep in mind is that "geneseed" is not static. The genetic makeup of the host. The genetic makeup and service history of the progenoid glands previous owner. Warp exposure.

I find it interesting that it can almost be taken by malcadors words like the primarchs fled, or abandoned their posts in a sense.

However many point to Russ comment about astartes vs astartes, however let's recall here that malcador whipped the memories of ALL the primarchs in regard to most info of their brothers.

There's one fact you did not take into account, the Soul Drinkers, who for most of their existence believed to be succesors of the Imperial fists. However, unlike their battle brothers, they were subject to unique traits and somewhat mutations, and that's without the fact that their lineage tests turned out to be inconclusive. If they were in fact succesors of the 2nd or 13th legions, it would somewhat prove that their geneseed was still being used to create space marines. Either that or the material inherited from their genefathers tainted their new progenoid glands when they were swapped.

Dunno if he had washed out before or after full or partial geneseed implantation, although he did kinda look tall.

[@casanovafunkenstein5090]

It's kind of weird to think that any legion could have done something so much worse than the civil war initiated by Horus and the traitor legions (leading to the Empire being completely stagnant as they are currently locked in endless, unwinnable wars against a mixture of abstract concepts and alien species that will eventually lead to a slow, painful attrition until all that remains is a bunch of rocks stripped of biomass and possibly some Necrons as the Tyranids wander off to consume another galaxy) that would warrant being completely expunged from all records so as an alternative maybe they were just complete failures. The Emperor was pretty cavalier about the stuff he was mixing in with his own genetic material, which is part of why so many of the legions had weird quirks and genetic abnormalities, so maybe the two that have no records for their existence were just too weak to survive. I can't imagine the Emperor's ego allowing him to admit any kind of failure so it makes sense that either he or his followers would have covered it up.

[@krimzonstriker7534]

I believe as the Astartes of the Lost Legions gradually died off, their progenoid gland was harvested as it would be from any fallen battle brother, but would afterwards be discarded. As you noted, the Imperium was capable of producing geneseed at that time at a much faster rate than the current day Imperium, capable enough to even replace those fallen Astartes geneseed with the geneseed of their new parent Legion into a new Aspirant.

[@thetalon100]

You forget, Inquisitor, about the Soul Drinkers. During their trial aboard the Phalanx, the Imperial Fists apothecaries came to the conclusion that the Soul Drinkers were not of Imperial Fists lineage. The apothecaries also stated that they “could not say” who the Soul Drinkers were derived from, and that their genetic sequences did not match any of the known Primarchs. This leads one to believe that the gene-seed of the Second and Eleventh Legions had mixed in the gene vaults of the Imperial Fists and the Ultramarines. As all data about the sources of this gene-seed was intentionally purged, over the millennia it became viewed as just more gene-seed of the Seventh and Thirteenth. Gene-seed is a beyond precious commodity in the Imperium, so it, much like the legionnaires who bore it, was most likely deemed too valuable to just be discarded. This is especially the case in the aftermath of the Horus Heresy and the Great Scouring. The Imperial Fists alone had such devastating losses done to them at the Iron Cage, that it took them *19 years* to fully recover. If one takes into account further actions such as the War of the Beast, the Black Crusades, the wars on Armageddon, and Throne knows how many more bloody engagements the sons of Dorn and Guilliman were in over the next ten millennia, one can be quite sure that maintaining healthy gene-seed stocks has always been a top priority for them. I enjoyed this video, brother, but I just wanted to highlight some possibilities you might have missed with this assessment. Keep up the good work :)

[@40KTheories]

Slight correction; Gethsemar said that they "could not say" which Primarch the geneseed of the Soul Drinkers belonged to, because "The Sanguinary Priests had yet to complete their discourse on the matter", so if they had more time to study it, they probably could have worked it out. :) As it stands, there is a surprising amount of evidence to suggest that the Soul Drinkers utilise Alpha Legion geneseed (the random mutations, which are in line with Alpha Legion genetic flaws, plus the genetic link to the Soulspear which could quite possibly be the Pale Spear of Alpharius for instance)

@@40KTheories very interesting! I have to say though that the Soul Drinkers don’t exhibit the particular nature of the sons of Alpharius Omegon. In fact their specialty in direct orbital assault puts them quite at odds with the sons of the Hydra. Though it is curious how the Fists would obtain Alpha Legion gene-seed to have a successor chapter come forth from that stock. Where on the flip side of that argument we know that the 7th did take warriors and *possibly* gene-seed from the 2nd and 11th. How would the Alpha Legion stocks get into Imperial Fists hands? Why would they even take them? Was it a ploy by Alpharius to plant a chapter of warriors in each of his brothers’ legions, or was it a chapter of Black Shields who stayed loyal to the Imperium rather than there fathers? As always with the Alpha Legion, that possibility raises more questions than it answers.

[@40KTheories]

The idea is that following the battle of Pluto, and Dorn's slaying of Alpharius, Dorn took the Pale Spear as a trophy. However, Dorn - ever the pragmatist, realised that the weapon was far too dangerous to let the traitors regain it, petitioned for the creation of a chapter to stand guard over to it, where they would be officially documented as Imperial Fists (and using AL genestock specifically, since the Pale Spear is also implied to be gene-coded to Alpha Legionnaires, much like how the Soulspear was gene-coded to "sons of Dorn" even though we later find out the Soul Drinkers are apparently of a differing lineage.) As for the mindset being different, you could argue the same for a lot of chapters. The Silver Skulls are very much unlike the Ultramarines for instance, being more superstitious and less practical. The Executioners are more brutal and aggressive than the Imperial Fists. The Wolfspear love utilising terror tactics etc. As such, it's not unreasonable to assume that a traitor legion successor could also sport a different mindset.

@@40KTheories That is fair enough I suppose. But getting back to my main point there are numerous chapters that claim to be founded by the 7th and 13th that have no actual hard data to prove they are of Guilliman’s or Dorn’s stock. Now that we know that these legions have both missing legion warriors in their ranks prior to Ullanor, it does make sense that some of these wayward sons survived to give rise to chapters with such shrouded lineages.

[@40KTheories]

It's possible, certainly. But it's also just as likely the shrouded records are due to the incompetence of the Administratum. Remember, the Administratum originally classified the Carmine Blades (back when they were called the Swords of Haldroth); a Blood Angels successor - as an Ultramarines successor

Sweet theory Video today. I bet Crawl uses them for primaris.

It would seem weird to me that Apothecaries wouldn't have noticed alternate genetic material; maybe now they could miss it, but the Lost Legions were struck before even the Horus Heresy, meaning that there should have been little time for evolution, or loss of knowledge. Also, if they were inducted into the Ultramarines, and not changed, I feel Guilliman would've maybe been less ironclad with Caul about using their material in the Primarus Project. Certainly, some Primarchs did present genetic oddities beyond what they passed on to their legion; Sanguinius had wings, but they don't crop up among the Blood Angels. Still, it would feel weird to have the Lost Primarchs bear such genetic abnormalities as to need to be erased and destroyed, yet their Astartes be pure enough to stand within the Ultramarines and Imperial Fists, and not draw attention. I feel little else could justify it; the Daemon Primarchs committed every affront against the Emperor, and they were never wiped from memory. It also seems weird that Astertes could just be "rewritten"; that Space Wolf or Thousand Sons could be tinkered into an Ultramarine, even with their canis helix, or flesh change and psychic abilities. I like t I think they were liquidated, and their seed locked away. Anything less feels like the eradication was unnecessary.
