FATE OF THE LOST PRIMARCHS! JAILED BY THE CUSTODES?

[@anxioussamurai9017]

I absolutely think at least one of the lost Primarchs is down there. As cold-blooded as the Emperor (beloved by all) can be, killing one of his own sons is something even he struggles with. Look at how much had to happen before the Emperor (beloved by all) finally destroyed Horus. I know a lot of people want their fates and identities to remain a mystery but I really, really want to find out more about them.

[@nopeuhhuhh3662]

Agreed. And.i don't think the emperor would have killed them, even if for no other reason than how much resources went into creating them. The emperor lead whole damned crusades just to find them he's not just gonna kill them off.

[@th3oryO]

I'd love to know more as well, but didn't one of the authors basically admit that 2/11 are deliberately removed so that the fanbase can speculate and homebrew their own legion and their primarch? The speculation itself keeps people engaged far longer than a known.

You know, I'm fine with not knowing the ultimate fates of the missing Primarchs, but the burning question I want to know about them is what did they do? That's the bit that I keep hoping to read one day.

[@danielbob2628]

There are very few possible explanations. They didn't turn to Chaos, or the events of the Horus Heresy would have been full of references to them. For similar reasons, they must not have: *Openly rebelled *Done anything major with psyker powers *Subverted the Imperial Truth in any way *Been victims of anything similar to the Butcher's Nails *Been simply too attached to their sons They didn't try to create any multi-species societies, because that would be the stupidest writing decision on the planet. They couldn't have simply been found dead by the first Imperials who ever saw them, because a specific passage in an Emperor's Children book mentions how they acted towards Fulgrim. I'm betting that one collaborated with xenos (Drukhari?) and the other had dangerously defective geneseed.

[@LordRydag]

They probably just died on the planet chaos sent them too. How embarrassing.

[@andrewniehoff8612]

Personally, I doubt we will ever know. My guess is GW left it vague before the HH books came out and then realized that with all the people who knew them running around someone would talk about it. Since they had no idea what to do they just have everyone say "It is too terrible to talk about" and leave it at that.

[@xenoscry]

@@andrewniehoff8612 tbh I would have agreed with you 48 hours ago. But after seeing the most recent video Valrak put up about 2/2/22, it got me thinking. The whole purpose of the 2 missing Primarchs was so that players could fill in the gaps with their own creativity. With so much about the space marines and their lore fleshed out these days I wonder if it would be ok to have one step into the universe once more. The war of the false Primarch would be an extremely interesting way to take this. What if the "forgotten" Primarch literally got displaced in time and instead of arriving to help with the Rangdan Xenocides he arrived in M33 only to be captured by the Inquisition. Suddenly the custodes having a Primarch in the dark cells might make sense. It could even be for his own protection from the very imperium that no longer knows who he is. That would be wild. If Gman found out and set him free it would be easy to cook him up a primaris chapter if he wasn't hostile.

I have a theory that one of them was sent to the future when the Primarchs were scattered by the warp. Possibly growing up on a world once loyal to the Imperium, but now ravaged by war. Where the fate of the Imperium is known to be a terrible fall to corruption and chaos. So the Primarch manages to make his way back through the warp to sometime before the HH and tries to warn his father of whats to come and after the things he predicted start come to pass, his Legion are absorbed into other legions and he is taken to Terra in secret to advise the Emperor, and all memory of him and his knowledge of the future is erased. It could even be that the "original" timeline of the Imperium was far darker than it currently is and only with the Primarchs help was the Emperor able to steer events in the most favourable direction. Its been said before that big E knew that half his sons would turn so maybe all that and his internment on the golden throne was simply the best option...kinda like Dr Strange in Endgame :) sorry for the long rant

Fairly simple deduction: Not killing them instead putting them on storage because: 1. making primarchs is a rather expensive investment and killing them just because they have an issue is not an option (see the case of Angron), 2. If E. distributed the respective legionnaires to other legions as it is suspected, they may need genetic materials.. 3. Just my own suspicion, because they have no issue, they committed no sin , they are just wildcards in a rather tough poker match with the 4 whom E had some agreements before . Having a couple of unknown primarchs hidden after making certain promises he had no intention to keep..is not that hard to consider. Just my thoughts ofc

Problem is, Primarchs are not your run of the mill problem, they are basically immortal beings, capable of going toe to toe with greater daemons. They are not easily contained and if one were to escape or change his mind about staying in prison, that's an extremely terrible problem to deal with.

My idea for one of the missing Primarchs is told by Astartes in this secret chapter which wears only black it is known as the Dark Wolves and my back story is a young aspirant decked out in armour black as night. He kills multiple altered senturys altered to exist on a radiated world guarding a secret listening post. A rickety lift takes them up from the drop sight of the first nuclear missile. The shadow breaks necks of some guards with such force he rips their heads of making the blackest of blood shoot upwards as he holds them slowly lowering the bodies to the dusty ground. In the Astartes lens he watches the radiation level rising . He arrives at the framework to the lift but the Astartes silently climbs without a sound not scratching his matt black armour. The last guards are walking patrolling the plateau where the listening station sits with aerial types picking up every voxed talk across the universe. The tracks of one show a foot and a reptilian tail supporting the guard. To cut it short one he shoots the other he eviscerated! He places explosives on to a heavily armored door .Slowly he backs away but inside a Adeptus Menchanicus Preist of the darkest evil moves towards the door his remaining part of his mind say investigate. Such a large explosion drops the adept off his rubber tracks, his thin metal arms are unable to push him up right. The Astartes whose been only a shadow as he took out sentrys one by one, the adapt finds his mind clear free for the first time in ten thousand years! Lying next to him is a figure covered in slime and it slowly grows as the Astartes fills his bag with STC information from these different listening devices! He turns as a feeling of eyes on his back. The creature came from the adopts mind and stands two meters tall. "What are you it asks ,the Astartes puts to bolt pistols rounds in its forehead. What are you as you move like Primarch Corvus, but your shooting is placed like Gulliman. I felt you running like the Kahn yet I smell Russ? What are you child the aspirant turned a faint growling came from his lips! Your built like the defender of the palace Dorn by your height is like a son of Vilkan ! The Aspirant removed his helmet with the sound of pressure seals decreasing in pressure . So my my the creature pronounced its voice female your face is of Sanguinius your one of his? The aspirant laughed we are the darkest chapter kept secret by a experimenting devout Priest on Mars you see demon my father its said was born with a little of all his family its said. But my chapter honours the wolf named Russ for when he came to kill him for saying the future for his father the Emperor who saw much but not everything. RUSS allowed his twin brother to leave with his thirty thousand warriors knowing the Emperor may punish him for giving life not taking it as well as thirty thousand Astartes brothers that was the biggest similarity of all was to leaman Russ and his lone wolf side ! My father ended his life the same way his brother lost his but he was reborn in the furthest place imaginable north where its said he lives still! As the Aspirant walked out through the bent door frame he fired every round of his bolt pistol into the creature while saying I am Achilles and a new brother of the Dark Wolves Chapter! Overhead a thunderhawk kept cycling waiting for the black armoured marine to leave . It fired multiple missiles in through the twisted door frame in to the listening machines and the creature now formed as a woman a single horn on her head and a snapping scorpions pincer instead of a hand.

[@clemo85]

I know I'm late to the party. But maybe the reason they were purged from all records is because they both transcended the physical plane. The Primarch's are considered to be a combination of genetic engineering and the Emperor's DNA. Maybe the use of his DNA was what was needed to allow Minor Gods he had collected/convinced to possess the Primarch bodies - this would explain why some of them didn't like him while others remained loyal, along with why the clone of Horus didn't have a Primarch aura and why Angron lost his upon ascension to daemonhood (his Minor God 'soul' left the Primarch's body or was subdued). Maybe the two lost Primarch's learned of what they were and spoke of it to the Emperor, who was obviously enraged and ordered them not the speak of it again due to this knowledge going against the Imperial Truth. Resulting in 'The Purged' to go against his father and continue to work on transcending back into the warp, only with greater power thanks to the Emperor's DNA. 'The Lost' could have been the one to try and stop his brother, culminating in their Legions battling and the Emperor present to witness their duel, just before 'The Purged' successfully transcended and became Malal. The reason I think this is because when Horus is being choked to death by Malachor, he tries to speak the name of one of his lost brothers and only gets out "M.. Mal.. al" before his windpipe is completely closed. Maybe after seeing the process to be able to transcend, 'The Lost' was encouraged by the Emperor to do the same to ensure his transcended brother was kept in check. Ending in 'The Lost' transcending back to its Minor God form and going into the warp to chase/battle his brother. The Emperor would then cease the fighting with his enormous psychic power and mind wipe them all before the timeline we all know - Dorn/Rowboat convincing him to spare the marines and have them join the Fists and Ultramarines, mindwiping the other Primarchs and anyone with knowledge of them and who they were. Finally labelling them as 'The Purged' (Malal) and 'The Lost' (the loyal son who may be battling with his brother for all eternity). This would also explain why Malal is able to be summoned into the physical plane, even though it's supposed to be a Minor God.

They could be used to keep a rogue Primarch imprisoned in their room to be dealt with at a later date. If that's the case, wouldn't every Primarch's chambers be warded? Did the Emperor expect something to happen where such precautions would be needed? 3) If the purged ones were indeed executed or imprisoned in the lowest bowels of the dungeons, why preserve the doors when all other traces have been erased or 'destroyed'? Nostalgia? What makes more sense if if one or both of them agreed to serve the Imperium in secret to atone for whatever happened.

My head cannon is they were on campaign together somewhere, and the 11th was up to no good, whatever that may be. The 2nd were a rather nasty lot but were loyal and didn't take kindly to whatever nonsense the 11th was prattling on with and turned on them real quick, maybe even too quick. The Emperor heard and sent Russ to end this bloody incursion by killing the second primarch. The 11th were a pretty big legion and fairly dispersed to spread whatever shit they're up to so the 2nd can't kill them quick enough before the wolves get there and the tides of the battle turn, until russ starts to see just whats going on and realises he's killing the wrong guys. But it's too late and most of the second is dead. Russ then has to get reinforced by the only close expeditionary fleet, belonging to the ultramarines maybe even headed by guilliman. Together they crush the remaining 11th legion elements. The second legion is in ruins, they number less than 1000 marines after fighting the 11th and then the 6th for so long. Their primarch is dead or in stasis mortally injured, maybe by russ? The remaining 2nd legion are absorbed into the 13th because they, now, really don't like the space wolves for obvious reasons. And the 11th is completely destroyed and their primarch killed. The emperor, ironically, sent russ to kill the wrong guy. And then russ, ironically, did kill the wrong guy, maybe. The Emperor has to hide whatever shit the 11th was doing to state this off, because it must've been pretty bad. And he has to hide the fact that he sent Russ after the wrong guy. He also has to hide that fact that marines can actually turn on each other extremely savagely, because at this time it's not something that's happened before.

[@VoltairePrime]

I like to believe that in those rooms one of them has a Primarch in Stasis, which was the “Forgotten”. Because he was slowly forgotten to almost everyone via time/mind wipes/or something else like that. Due to the Horus Heresy and the 10k years passing by. And the other one which is the “Purged”, has a Coffin where his body resides, because I sorely believe this one died during the Rangdan Xenocide, and the lost of a Primarch would’ve been disastrous for the crusade. So he purged him from history.

[@ianharrison5758]

I can see the 11th primarch being in stasis in the dark cells. Even if he doesn’t do anything, just knowing he’s alive would be insane. My headcannon is that the 11th, (and maybe even the 2nd but probably not) was put in stasis to be part of a doomsday contingency. The terminatus decree would be to release the 11th, and at that point you can go all kinds of directions with how a story can go. One of my homebrew lost primarchs is a techno path that specializes in AI. I didn’t make him for the table top, just to fill in holes in the lore, so he doesn’t actually have a legion and instead basically went around collecting, destroying, hiding or reverse engineering powerful tech.

There is some lore that suggests at least some of the prisoners in the Black Cells are the other Perpetuals who turned against the EoM. They are in the cells, because as Perpetuals they are almost impossible to kill. Oh and all memory of the 2nd and 11th Primarch's were eventually removed from the minds of all remaining Primarch's by Malcador. So that they only remember they existed and something terrible happen with them. Though based on Horus's reaction to them during the Hersey. Malcador may have implanted the idea during the mind wipe, that it was probably the best option at the time. We also know it was Dorn and Guillmen who saved the surviving members of the lost two legions. Successfully convincing the EoM that it was the Primarch's that failed and not the legionaries. So the survivors were absorbed into Imperial Fists and Ultramarines. Probably after having their minds wiped and their gene-seed switch out to their new legion. But if the lost and forgotten are in the Cells or that place Dorn found. They may be in stasis for all time.

[@locomastero]

I have a theory, the lost Primarchs were among the firsts found by the Emperor, BUT they were already corrupted by the forces of Chaos or other entities, so they were locked away so no one could know about what happened to them, and to keep the secret well hidden because of the possible consequences this could bring to the wider Imperium and the other Primarchs.

I mean the only reason 2 legions were lost to begin with was so people could do homebrew legions I like the idea, but honestly you don’t need 2 legions to be missing in order to make a homebrew primarch. If it’s a fan fiction, do what you want, and if it’s for table top, just make the legion and use an existing legions stats for your play style. Idk abt y’all but I’m the only person I’ve ever met who made a homebrew lost primarch(getting a model commissioned soon) and I didn’t even make it for table top. Tbh I don’t think there is even a big enough market for homebrew legions for it to make sense leaving them secret. GW can make a whole lot more money implementing them into the lore for 30k, or if they are feeling spicy, bring that mf to 40k.

[@ianharrison5758]

I’m actually working on a 40k fan fiction where the heresy never happened and both lost Primarchs survive. This is relevant to your comment bc in the story, I made the 11th primarch a super pariah. Ill write out a description of the general plot of the story and how the 11th fits into it below if you’re interested in reading it. The story is lore friendly but I also changed a lot so be prepared for that. It’s also gonna be long as fuck. The story is told from the perspective of the 11th primarch and begins on the Dyson sphere he landed on after the scattering, and continues until long after the webway project is complete. The 11th primarch, which I named Draazen, is entirely unique among his brothers. In my fan fic, he doesn’t have a legion and was designed to be an assassin rather than a general. The reason he has no legion is bc in order to create a pariah primarch, the emperor had to create Draazen by inverting the polarity of the god soul inside him. (In this fan fic the primarchs souls are actually minor warp entities created by humanity in the past) and create Draazens body without the use of the warp. As a result, Draazens geneseed cannot be replicated to create Astartes. The emperor knew this from the beginning, and made Draazen to be a hunter, not a conquerer. While his brothers conquer worlds and exterminate xenos, Draazen hunts the most powerful denizens & users of the warp in the galaxy. To give an idea as to how powerful these beings are, the super Khrave the lion fought would be on the lower end of the scale in terms of power. There aren’t many pskers in cannon that powerful, so I created several unique Xeno Psykers and warp entities that manifest in real space to make up for it. These entities have psychic power on either a scale so huge, or a nature so unique that a legion would be a liability in their presence. They could simply turn the legion on their primarch with a thought. Draazen hunts these beings in the shadows, traveling in a single DAOT star ship, crewed by loyal AI(he was raised by AI, and only joined the emperor if he let him keep using them in secret) a navigator, and 3 astropaths. Draazen is also not like other, naturally occurring pariahs like the SoS, or the Colexus assassins, who have powerful auras but no way to control it without technology. He is able to control the nature of his aura, but not it’s intensity. He can choose to make you feel anger, fear, pain, etc at will, allowing him to assault the mind and body at the same time in combat. Draazens null aura is so powerful it can lower the emperor and malcadors power level , as well as interfere with the astronomicon should he get too close to it. To counter this, the emperor and Draazens AI companion created Draazen a suit of armor that can contain his aura and control its intensity. With this armor on, his null aura is stored and stock piled. Should he allow none of his energy to escape for a week, it wouldn’t dissipate, it would stay there until Draazen released it. He can do this slowly or all at once, the latter able to give greater demons true death instantly. He uses this power in concert with his twin one handed scythes to cut through warp spawn like a hot knife through butter. Some notable missions hes been on so far: 1. Killing the Saellenarc, the last member of an ancient extra galactic Xenos race that invaded the galaxy during the peak eldar empire and lost a war to them, with only the most powerful still around. The Saellenarc essentially had the unique power of twisting all warp energy around them, with any use of the warp by others resulting in the warp burning them from the inside out. Even Magnus at his crusade power level can’t reverse the effects(the emperor knows how to tho) Draazen killed it by releasing a months worth of his stored aura directly in front of it. 2. Capturing the last old one. Draazen did this by using himself as a lure to lead it into a building secretly created with black stone and covered in rubble to disguise the trap. With the black stone nullifying the warp, it was easy to contain. It now resides in stasis in the black cells. 3. Banishing the demon inside the laer blade Fulgrim uses. Draazen did this entirely on accident. Fulgrim disrespected tf out of him and challenged him to a duel. Due to his role, Draazen is one of if not the best fighter out of all the primarchs, with only a few like the lion, Russ and the angel that can match his skill with a blade, and none that can counter his aura should he use it on them. During the duel, without any understanding of Draazens purpose or nature, Fulgrim taunted Draazen, saying he has no purpose in the crusade except to pick up his brothers trash, and that he was the only primarch unworthy of a legion. In response, Draazen mocked Fulgrims skill and pride, saying, “I have no legion because I do not need one to fulfill my purpose, you were handed yours because you’d get no where without them. The true test of worth isn’t in your ability to claim your birthright, it’s in the knowledge and power you earn. Our father deemed me worthy to know secrets you may never be told. Our father deemed me worthy to destroy foes he’d never send you to face. Our father deemed me worthy of knowing his grand plan. He didn’t even deem you worthy of knowing what I am; or what I do.” This caused Fulgrim to lose his shit and allows the demon inside the blade to influence him into trying to actually kill Draazen. the fact Draazens aura was fully contained allowed Fulgrim to leverage the power boost from the demon sword and wound Draazen. This causes Draazen to release 1/10 of his aura on Fulgrim at point blank range, forcing the demon out of the sword. Once the demon is free, Fulgrim passes out and Draazen leads it away from his brother before releasing the rest of his aura and giving the demon the mother of all banishments. Holy shit this comment is long. I highkey typed wayyyy to much but I didn’t do all that just to delete it. If you actually read all of this lmk what you think

[@Dontreallycare5]

I think it is highly likely they are kept alive specifically because their legions were sparred and still seen as useful - because executing them would create psychic backlash that would wound their entire legion. The memory wipe might not even be specifically to keep the primarch's away, but rather is an extremely long running experiment to see if those legions will be psychically detached from their origin primarch eventually, and become attached to another primarch they don't necessarily share genetic heritage with. The Forgotten might have even volunteered for such a duty if they were not interested in leading their legion and simply refused to do such . . . perhaps even specifically created to be something of a pacifist - and for the young Imperium, him convincing his brothers to stop the crusade on morale grounds would be just as much a threat to the Emperor as them turning to Chaos . . . . but eventually after the crusade has finally succeeded, they would become an incredibly useful tool for stopping future civil wars.

[@georgem9981]

Lost primarch theory People know that there are two lost primarchs, but no one knows what truly has happened with them. And so here’s my hypothesis & thoughts along with it, the reality behind the curtains. *Hypothesis* *1.* My first hypothesis is that The lost primarchs were a wayward reinforcement or free survivors. So a while ago, I had a thought that the lost primarchs were Emperor’s plan of saving the humanity from the brink of the annihilation. I hypothesized that Emperors would wage war upon the ruinous powers. Which would end in either weakening of humanity or the end of both ruinous powers & humanity. If the weakening of the Emperium would have happened, the Emperium would have required new forces to combat the ruinous powers, to continue & win the war. Which is exactly where the lost primarchs would come in. Emperor would create two primarchs and send them off, into another galaxy. To conquer it and return back to the milky-way Galaxy when the time is right. They would return as a reinforcement to the emperium in its dire time. Or the lost primarchs would perhaps return as the free humanity, who would reclaim the legacy, left by Emperium after the war with ruinous powers. When both sides no longer exist. In order for this to go as planned, Emperor, changed, altered and erased the memory of everyone else. Making everyone belive that the lost primarchs were either traitors or failures. Who were executed & expunged out of the imperial records. All of that made as a backup plan for the survival of the humanity as a race. *2.* [Warning! This is a mad theory] After watching this video, I’ve come up with another hypothesis. A hypothesis about Emperor locking away 11th primarch for the future. The Lost primarchs number is 11, subsequently it is also a sacred number of a Lost God called Malal, also known as Malice. Considering that there is a jail-chamber under emperor’s palace, with the number 11. It could have been that the 11th primarch. I hypothesis that the 11th primarch became a champion or a prince or an avatar of the lost God, Malal, also known as Malice. Which could have happened when the warp rift were opened in the lab with tubes that contained the Primarchs. Or perhaps the when scattering occurred. 11th were locked up to be cured later. When the war with the ruinous powers are over and said powers are no more. So by that logic, the warp powers within the 11th should be neutralized. Warp would still be within him, but would not have a tremendous effect. That is, if the Emperor’s plan was to kill ruinous powers by starvation. However, there is another possibility. And this is where “God Emperor” comes into the picture. Emperor locked up the 11th primarch, for the future. Because Emperor secretly knew that he must become a God in order to save humanity. As it is the only one way. So he tricked everyone into believing that he does not want to become a God. Which means that the Emperor deliberately & purposely cause the destruction of Monarchia. In order for Lorgar to betray the Emperor and subsequently make Emperium religious. Emperor knew that he must become a God, not only to save the humanity but also to cleanse the 11th. The cleansing would have happened By replacing an essence a God within 11th. For example, if 11th would have the essence of Malice within him, than the Emperor would have replaced it with his own. That would occur when Emperor would have become a God. All of that, in order for the 11th to be bound to Emperor and not a chaos God, for him to be a loyalist. (Bit of explanation. If a living being within Warhammer 40k is a vessel. Then it can fit in both the essence of a God and the warp powers. Example would be Mortarion, the primarch of the Death Guard. He is filled with warp powers but has elements of Nurgle within him. I believe that is done through imbuing Mortarion with essence of Nurgle. Thus granting, said elements of the nurgle, specifically Mortarion’s wings.) However, this also raises a lot of question. Specifically, why did Emperor lock up the 11th in a jail and not kill him. I believe that he could kill him because of three reasons. The first reason is that the 11th is his son. And so Emperor couldn’t kill the 11th Because he is his father. Which is the reason why he could not have brought an end upon the 11th. The second reason is subsequent of the first one, which is, that if Emepror would have killed his own son, as such action would have led to rebellion and revolt amongst people of the emperium. And so the emperium would have met its demise shortly after its birth. The Third reason is, Emperor couldn’t kill his 11th son, but could let him roam the galaxy. Because if one of the primarchs are a spawn of warp (a demon prince or what have you.), than the people of the emeprium would have questioned the both authority and competence of the Emperor. Thus causing quite a stir, as such would have caused a Emperium to stand upon a shaking ground. Which would lead to its demise in the long run. If the 11th would roaming the Galaxy and being a spawn of warp. It would be the spark that would ignite a keg full of gunpowder, a keg of riots and rebellions. Along with ruinous powers & warp effecting people of the emperium. As for the 2nd primarch, he could has been killed by the 11th, which is why there are no records of him. Emperor decided to expunged him too as it would hidden the truth about 2nd demise & 11th being a spawn of warp. In order to avoid the shaking ground that would have lead to the demise o the emperium. **The Reallity of it all.** But the reality is far less complex and way more boring. Both GW and Fandom are lost & confused about the two primarchs. Regarding the Fandom, people will always speculates and come up with own theories for what have happened with the primarchs. And what have the lost primars done to deserve to be expunged and executed. Or why there are no records of them anywhere. But no one will know for sure. Regarding GW, it also has information about the lost primarchs. Both within the WH40k universe and outside said universe. The reason to that is that the lost primarchs are a reference to the two ancient Roman companies. Those companies were annihilated and it is not known by who, the company numbers were lost to the history. And I suspect, since there are nothing about the lost companies that are left within the history. GW simply has nothing to write about the lost primarchs. As a conclusion to this. Of course this leaves A LOT of free space for the fantasy, but considering that GW, at this point, are confused about primarchs I doubt that they ever would create something them.

[@ChimpFromSpace]

My headcanon is that out of the 20, the 2nd and 11th primarchs ended up being sent to xenos homeworlds. Perhaps leading to one of them sympathizing with a particular xenos race. Maybe one of them refused an order, or maybe it was just Big E, and space Gandalf simply decided they were a liability.

[@michelletheia9853]

My head cannon has been that one was raised by benevolent xenon, maybe even growing up on an eldar craft world. He took command of his legion and was happy to battle orcs and mindless threats, but refused to attack non-belligerent eldar, maybe even defended his home craftworld from another legion. The other I’d always thought maybe landed within the eye, and was too corrupted to be of use to anyone, maybe even the first primarch to embrace chaos. Hell, what if the rangdan xenocide was a cover story, a real event blown out of proportion to hide that the real war was against this daemon primarch and his legions of chaotic followers, with some of his legion turning to follow him. In the end this gear daemon primarch was destroyed by E (and his sword), and all memory of the event removed from the primarchs’ and legionaries’ minds

[@Nyghtking]

For fun I had an idea that was just a conversion of the Doom Slayer as one of the lost primarchs, thrown into a chaos world and empowered by Malal, this primarchs only desire is to destroy chaos and nothing more, being granted incredible resistant to chaos and psyker powers, a scatter bolter that will never run out of ammo and can cut through demons, and a chain sword that can cleave through demons with ease. His issue was that he doesn't care about anything other then destroying chaos, so it was difficult for the emperor to get him to do anything, especially when he isn't suppose to know about chaos in the first place, so he's simply kept in stasis until such time as the emperor deems fit to release him.

I like to think that the fates of the two missing Primarchs and their legions were tied together in some way. That there was a flaw in the purged legion’s geneseed that necessitated their being ordered purged. All but the forgotten legion’s Primarch accepted the Emperor’s decree and he tried to stop the purge and to resist the Emperor’s cruel sentence. The other Legions and their Primarchs did nothing to support this and now attempt to “forget” this secret shame that one brother and his legion did what the others didn’t have the strength or courage to do, oppose their father-emperor’s will in defence of their brothers.

[@tomhatton2512]

Love this video. Speaking of Love... My theory is that there is one part of the Emporer that's not expressed in a certain way which is what one of these Primarchs would have been styled around and that's love. There is love for humanity from Vulcan and love for their legions by all of them but not a pure kind of love for another being. The other embodiment is diplomacy. That could be for say primarch 2. Here goes... I think the diplomacy primarch ends up fighting lots of greenskin and ends up teaming up with Eldar and once it really gets going he has 11 with him too. This is enough to piss off the Emporer who summons 2 and 11 back to Terra. On arrival not only has 2 created a full on peace treaty and has Eldar in his battle force but 11 has only gone and fallen in love with an Eldar Princess. Maybe even there's some wacky half elf nonsense at play. This enrages the Emporer who orders Russ and the Custodes to take them into the cells but in the commotion Russ kills 2. In know it's far fetched but it's my theory and I'm sticking to it!

[@Pannenberg]

I have only just begun diving into Warhammer lore, but I love these big mysteries. I hope its not just that they fell to chaos in a manner similar to Horus. I have a million different scenarios in my head because its fun to think about (to the extent I hope that we never fully know their fate, and are only given hints). But one scenario for my head canon is that one of the primarchs had something similar to techno mancy, or the ability to speak and interface with machines to such an extent that, not knowing of the history of the men of iron, made contact with a lingering AI and combined with it. And/or that this technomancy was of such an extent that the emperor ended up fearing it might damage his position with mars as omnissiah as this primarch's abilities were such that he could compete if not supplant the emperor's position. And for the other, because of the theories that primarchs have some warp entities stuffed into them, or at the very least warp mechanics going on that the emperor either stole from the chaos gods or whatever, that one of the missing primarchs was of such a hybrid between warp /soul and flesh that his specific nature among primarchs could provide the Necrons a key to understand how to finally transition back into the flesh. And that this Primarch in particular, given that primarchs seem to have been scattered to worlds that fit their natures, was scattered to a Necron tomb world and in fact was either partially or fully inhabited by some hitherto unknown necron. Like I said, all pure speculation and no doubt I'm missing something in the lore that would prohibit it, but its fun to think about.

[@MADSAHAD]

First I want to say, great video. The two lost Primarchs, The Lost and The Purged or The Forgotten and The Expunged etc. Can we all come to an agreement that the Primarchs in themselves are and were a sliver reflection of the Emperor, as if the Emperor fractured himself into 20 different images of himself of 20 aspects of himself. Each one with a separate and unique role to play in the grand scheme. If we can agree on that, than let us go to the next step. Each Primarch is an aspect of the Emperor but in microcosm, the two lost Primarch are two aspects of the Emperor that the Emperor may not want the rest of the universe know about or they themselves are or could be direct opponents to his grand Scheme either being to closely in thinking like the Emperor or in complete opposition to him. Meeting one could be so like the Emperor that the Emperor worried that he had made his own usurper without the usurper knowing that they were going to be a usurper later in time and the other would fight me at every step or be that thorn in his side every single day. One openly opposing him while the other covertly/ unconscious opposing him. So the Emperor, being the Emperor eliminated them before things got out of hand. Some would say, "Well, if he knew that about the 2nd and the 11th, what about Horus? Why wait and allow Horus to do all that what he did?!?" Simply, Horus was pushed over the "edge" by Chaos where the 2nd and the 11th weren't. Its the difference between ticking time bombs and a pressure switch mine. One is preset to go off after a perset time the other needs someone or something to push on the pressure plate. The 2nd and 11th could have been seen as Clear and Present Dangers while the others were seen as problems for another time. Just my opinions 😊

Rangdan+a whole legion and primarch definitely explains why the Dark Angels w/ super weapons and the Space Wolves had to both be called in to deal with it.

[@bernardotorres5274]

I do believe that this cells are for the Primarchs, but not in the way we imagine. Let’s remember that the Emperor not only created the primarchs to be the generals of his crusades, but also replacement for the other Eternals that abandoned his plan. To the Emperor the Primarchs (even though his own flesh and blood) were nothing but tools on his campaign we even see that sentiment when Guilliman returned to Terra and went to talk to his father, instead of a warm welcome a father would give to a lost son he loved, he treated Guilliman in a cold way similar to how someone reacts when they finally found the tool they were searching. To the Emperor the Primarchs are just tools, however they are irreplaceable tools. Now if we are to be believe the theories that Primarchs not only having some of his father abilities but their very souls are actually minor Gods of the Warp, it could explain why the Emperor doesn’t discard/replace them like any other tool, because they are way to unique and powerful. This will put into question what are the missing primarchs and what actions lead them to being forgotten. From what we know they did not betray the Emperor because if they did they would have been written down as traitors, and they were not they were called “ThePurge” and “The Forgotten”. The Purged or the Second Primarch I liked to believe that he was heavily mutated or that his body reacted poorly to the soul of the god that was bestowed on him. This the Emperor was forced to purge the body but keep the God Soul in order to try and create a new body. The IX Primarch or “The Forgotten” I like to believe that his fate was either that we was consumed in the warp when their containers were spread across the Galaxy, thus becoming one with the Warp and he manifests himself through the Legion of the Damned and he is the actual force behind the many Saints/Emperial demons instead of the Emperor himself (or one of his shards). Let’s remember another name given to damned souls is also forgotten souls. I do Believe the IX cell is the one that holds a future body of that Primarch if Malchador and the Emperor are ever in the need to retrieve him from the Warp, although at this point (if we follow my theory) his aid in the form of “The Legion of the Damned” is far more useful to them in that way. Anyway this is just my speculation, you tell me what you think.

[@mio87]

I think mystery about these two Primarch was nice when we player can create own SM chapter. But now I think most people nodays want to know the lore and story. I think that GW should tell the story and maybe using it to present 40k lore. If Curze, Alpharius, Omega and Horus are dead then CSM can get new primarch in their collection.

[@athatcher9367]

Okay, given how much it took for the Emperor to be willing to kill Horus… I don’t think he’d kill them or let them die (if he could at all help it). I also have trouble seeing geneseed problems (which seems like it’d only be a problem for a legion) being a reason to kill or imprison a PRIMARCH unless it was something that affected the primarch themself very badly. So, the way I see it, either they are imprisoned for breaking some rule (perhaps refusing to fight or some mental issue that was so bad even big E wasn’t willing to use them in combat), literally just going missing into the warp or deep space, or were killed by something else… I have trouble seeing anything at that point in time really killing them though, save another primarch or a very anti-climactic ship malfunction… So I have to imagine that if they are dead then those cells have their bodies or they’re alive and in stasis or agreed to stay there and are living a life of luxury… (or maybe one of them got nabbed by the dark eldar… which I shudder at the thought of) plot twist, they were Alpharius and Omegon all along! Or other plot twist: the terminus protocol lets them out of their cages.

[@blackmanta96]

[@overgrowndwarf1628]

Linguistically, how they are referred to in lore is very telling. The "Purged" implied they were completely excised - destroyed, and all vestiges expunged. It's heavily implied in various sources that the 2nd transgressed to the point that no legionnaire was allowed to continue living - the exact nature was unknown, whether a contamination, mutation or defect - but it was most likely NOT a rebellion or traitorous act. Whatever it was, it was: -> Ubiquitous. -> Inherent. -> Contagious. -> Dangerous, even to Primarchs, maybe even the Emperor. We known this because gradual changes like the "Red Thirst," which is a slow process, and not universal in the Blood Angels, was enough to cause Sanguinius to fear they would suffer the same fate - however, was not prevalent enough to cause the Emperor to extinguish the B.A's. Likewise, the "change" the Thousand Sons underwent was certainly prevalent enough, but still did not rise to the level of danger as to be a threat - as the thousand that remained unaltered were saved and allowed to continue to operate by the Emperor. Even the Space Wolf mutation turning Asartes into Wolfen was largely ignored. Whatever their flaw was, it warranted the same treatment as malignant cancer - not just a removal of the Primarch, but a total purge ensuring it could not threaten the Imperium. The "Forgotten" is only ever used in the singular, as if it referred to a singular being. This implies the 11th had their Primarch "removed" (but not necessarily killed) but not that the legion itself had to be exterminated. Many books reference the Ultramarines as having swelled in numbers coinciding with that period, the insinuation being the non-offending legionnaires were close enough in ideology and culture to be able to be absorbed by the Ultramarines and continue to operate in cohesion. This raises a scenario that maybe the 11th is not only alive, but is known about and is active in some way. Given that the Ultramar concept and ideological root is Romanesque (what if the Roman civilisation had progressed and remained dominant into the modern era?), there does exist a contemporary parallel that mirrors such a real-world mythos - the Minotaurs Chapter. They are an unknown chapter, springing up suddenly at the behest and control of the Lords of Terra. Their iconography and customs are that of an Ancient Grecian civilisation advanced to a modern setting - specifically a Cretian motif with a very Spartan idiom. What if the 11th's homeworld was near enough to Macragge that their absorption into the Ultramar Empire was virtually unnoticed, and their culture and practices, being Grecian analogues instead of Roman, were close enough that the adoption of Ultramarine livery was not distinct enough for the Astartes of other legions to immediately differentiate between a "Minos" Ultramarine and a "Macragge" Ultramarine? How close is an "Athenian" ideal to the "Pax Romana" style governance of Guilliman? The modern iteration of the Minotaurs have many factors that lead me to believe they could very well be a chapter created by the Lords of Terra from 11th Primarch gene-seed, trained and marshalled by the 11th Primarch himself. They are exceedingly efficient and effective, being characterised by brutality, but never rising to atrocity. This is how I imagine a 40K galaxy would view a 30k Astartes. A modern chapter, trained by their Primarch, with a Great Crusade mindset would certainly fit such a description. The driving ideology the Minotaurs are motivated by would certainly match a Grecian idiom, if Sparta and Dacia were in ascendance, and the philosophy and culture of Athens had no influence on their development. The members themselves are also disdainful and scornful of other Imperial subjects and forces. Almost like the view of a once great and proud nation that no longer has a place, no longer has the part of their psyche that entertained philosophy, but is given over fully to a militaristic mindset. Being "purer" and taught by their progenitor, the soldiers would take on the "Grecian" themes of their Primarch's homeworld, and they themselves would feel "above" their 40k equivalents. Their brooding and their melancholy certainly fits a group who's father has been stripped of honour, glory and homeworld, but had not turned traitor and never been executed. They also take to the field utilising wargear that a 30k general would be more familiar with - Tartaros-Pattern Terminator suits and Spartan Assault tanks. All of their Dreadnaughts are Contemptor-pattern. They move as one chapter, as a whole whenever possible, or with as few divisions as possible - much like a legion would. All in all, their deployment and loadout resembles that of a Horus Heresy era legion and not a 40k Chapter. ___________________________________ Regarding the separate apartments: it seems unlikely that an entirely new structure, with entirely new apartments would be constructed and furnished AFTER the 2nd and 11th had been Purged and Forgotten, separate and distinct from the rest. If the Lake Retreat was built after they had been expunged, why bother to build them at all, if they were never going to be occupied? The plinths were still there, so it's not like having 2 empty residences in the lake retreat would be unusual for the others either, or they could have been simply demolished. It seems much more likely that the 2nd and 11th residences were created concurrently with the others, and deliberately constructed that far away from the others. They were always intended to be removed from the others. They were never "relocated," their quarters were exactly where they were always intended to be. Something about the 2 lost Primarchs was dangerous or harmful to the others. Then we have a Iron Fists Librarian able to sift through the psychic traps of either the Emperor or Malcador in order to gain access. Maybe I'm over-egging the Emperor's pudding, but Magnus would be the only one who would come close, surely. A Librarian, especially from a legion not exactly renown for their psychic prowess, should not have been able to get past them... unless they weren't directed at intruders. What if they were designed to keep something IN, and had the residual effect of making access difficult? What if the 2 residences were intended to segregate, partition and contain the 2 Primarchs after they had served their intended purpose?

As much as I love that theory, it is going to take one hell of a writer to pull it off. There’s a lot of hard questions to answer. What are the primarchs doing?, Are they working alone, or with a Legion? If they were free during the heresy, why did they not return to Terra to defend it? Why have they not been seen since their erasure, not even a whisper of a rumor of a sighting? There’s such a lack of information abt the lost primarchs that crafting a narrative that explains why they are so important and why they needed to be kept secret is going to be hard as fuck. My fan theory is that the 2nd primarch is using some spicy dark age tech to travel outside the galaxy and find the body of the Tyranid Hive mind. The 11th primarch is in the vaults of terra, and the terminus decree is to release him and let that wildcard throw the chaos gods off for a while. Neither primarch would be any more powerful or capable than the others, but they would be extremely specialized to fit this role. The primarch sent the scouts to find the source of Tyranids might be an incredible navigator able to make his way through the warp even outside the galaxy. The 11th might just be unpredictable as fuck and serve as a good way to fuck with the architect of fate

I believe one of the primarchs fell to chaos in front of all his brothers revealing the entire truth of chaos, the warp, and the source of how the big E came about many of his powers (gifts from the chaos gods). In a fit of rage and empowered by chaos he attacks the Emperor and seriously wounds him. The other lost saves the big E by sacrificing himself either in combat and dying (mirroring Horus/sanguines) or by giving up his power (maybe he’s a perpetual like Vulkan or super psychic like magnus)to save the emperor. Russ, Dorn, and Roboute then hunt that primarch and either captured or killed him. After learning about Chaos gods and how big E got his powers, Dorn and Roboute want to forget it less they fall down the same path. I believe this all happened on that planet with the chaos gate that Horus went to to get his Chaos gods power up where he faced millenniums of trials by each god in the warp. The emporer made them forget that place and for some reason that failed on one of the lost primarchs who took his brothers back there to the gate.

I think one of the lost primarchs became the avatar of Malice, the god of Anarchy. This is because Horus once attempted to say one of the lost primarchs' names while Malcador was strangling him. "Mal.....M-Mal...al" I think one of them ascended to become either Malice's avatar or even the god himself. The primarch's name might've been Malal, the god of anarchy from Warhammer fantasy. This god isn't truly non-canon, he's either been subdued, or erased from existence. As for the other primarch, I think they at some point rejected the tenets of the Great Crusade and allied with an alien race powerful enough to oppose the Imperium of Man, and possibly allow another alien race to dominate the galaxy because this primarch HATED humanity and saw them as evil. This failed, and led to what is now known as the Rangdan Xenocides. Both primarchs were erased from history because knowledge of them was a kind of Basilisk, Malal, grew in power from anarchy and betrayal which he in turn encouraged, to even know of him was to incite betrayal in a way similar to how Lucius the Eternal will resurrect from the body of an opponent if they take the slightest pleasure in defeating him. The primarch that worked with the Rangdan promoted anti-imperium and anti-Emperor rhetoric that challenged the resolve of all the primarchs and could've splintered humanity or even inspired mass suicides undermining the species from within. That or maybe one of them was a Pariah and freaked even the emperor out so they just memory holed him, the other one killed themselves and thus dishonored the imperium

I had one of my missing primarchs called Voltan and he was jailed by the emperor because he kept argueing with the emperor on exterminating Alien species. He kept argueing that some Aliens would make excellent allies rather destroying them out right. In the end Voltan went behind the Emperors back and saved some Aliens races and kept them safe in his zones of compliance but the Emperor found out and sent Horus to bring him back for trail and Russ to destroy the Alien races saved by Voltan. It was Horus and Russ that convinced the Emperor not to destroy Voltans legion as Voltan had surrended his legion over to Horus and Russ with out a fight as he did not want to fight his Brothers due to him loving them both. Voltan excepted his punishment and his legion was split up and spread among the other legions. My other primarch was called Genggis Hadesaki and he was a very brutal priatelord and had a massive space fleet befor he joining the Emperor. He was also a bit of a skitso and very brutal but some times kind and he was know for stealing from the other legions he was also know for giving gifts to his brothers and then argueing with them and the Emperor on every thing regarding space fleets. But he did admire Horus and it was only Horus that Genggis would sort of listen to. His down fall came when he had argued with some of his brothers regarding a complaince of a world and when in his eyes the complance was reciveing stiff resitance he basicly said i told you all to do it my way and you all refused so he refused to aid his brothers in the battle its only that Ferrus came to there aid that disaster was prevented Genggis was orderd to meet the emperor but he refused and destroyed the ship bearing the message. So Horus was sent and Genggis done the unthinkable and fired on Horus fleet resulting in a mega space battle. The Battle lasted a month of hit and run and all out assults but in the end Genggis flag ship went super nova with all hands onboard his fleet was destroyed or captured and some think Genggis escaped in a small skiff but most belive he died on his flagship screaming insults at Horus and then pleading via vid screen befor his ship went super nova. Either way he has never been seen since.

[@andruchuk]

Given capsule XI is the one that Horus damages before they're scattered by the rift, my guess is at least some physical/mental warp corruption from exposure. The nature of the warp was kept under wraps during that time, so it would make sense to purge/redact to keep the nature of the warp hidden. What primarch XI became may indeed be subject XI, captured but not destroyed. A primarch with wings is passable, but maybe not one with tentacles and extra eyes.
