Changes

However, nothing is known for sure about the names of the legions, their Primarchs, homeworlds and their ultimate fate. There are conflicting reports as to whether the two unknown Legions met their fate prior to or after the [[Horus Heresy]] and which side they joined in the Heresy if they participated in it.^{{Fn|5,7}}{{Fn|9}}

*The [[Emperor]] created 20 Primarchs, who were snatched from [[Terra]] by a [[Chaos]] vortex and scattered around the [[galaxy]].^{{Fn|1}}*The 20 incubation capsules drifted through the [[warp]] for decades or even centuries, until finally coming to rest on [[human]]-inhabited worlds throughout the galaxy,² {{Fn|4}} "where they were variously adopted by human parents."³{{Fn|7}}

*Of the various abilities possessed by the Primarchs, one was "invisibility".³ {{Fn|7}}

**This could also be referring to [[Corax]] who is said to have effective invisibility, whereby he could walk amongst people without them noticing him. It is also said that only the Emperor knew this about the primarch.^{{Fn|17}}*The Emperor met each Primarch in turn, and each Primarch had risen to a position of authority within the cultures they had found themselves in.^{{Fn|1}}*20 Legions took part in the [[Great Crusade]], each led by their own Primarch.⁴{{Fn|8}}

*20 statues of the Primarchs were erected in the [[Imperial Palace]] on Terra. By the time of the Horus Heresy, plinths '''II''' and '''XI''' "...had been vacant for a long time. No-one ever spoke of those two absent brothers [and] their separate tragedies."⁷{{Fn|9}}

*All Primarchs were tempted by Chaos predations, and "fully half" of them failed that test.^{{Fn|5}}

**Prior to sending [[Sigismund]] and his Imperial Fists to Mars during the Heresy, Dorn muses to [[Malcador the Sigillite]] on the loyalist support of two legions, possibly the two unknown legions, during the Heresy. Malcador quells the Primarch's thoughts, stating that "They are lost to us forever."^{{Fn|15 }} *Horus convinced "no less than 9" Space Marine Legions to side with him at the onset of the Heresy,⁸ {{Fn|2}} a number also referred to as "fully half" of the legions.⁹ {{Fn|6}} When he assaulted Terra, this number was given as 9.^{{Fn|10}}**This also implies, but does not categorically states, that the 9 known traitor legions are all of the legions that followed him into rebellion and that 18 legions were the total number of legions active at the time. A passage detailing Horus' plans for the various legions at the outset of the Heresy mentions by name all 18 known legions^{{Fn|11}}.*"Of the original 20 Primarchs only 9 survived the Horus Heresy. The remainder were either killed in the fighting (like Horus) or fled with their [Legions] into the [[Eye of Terror]]. The survivors helped [to rebuild] the Imperium."³{{Fn|7}}

Second edition's Ultramarines codex states that ''it seems likely'' that Legions II and XI ''fought for Horus at least during the beginning of the Heresy''. It also refers to the records as being destroyed following the Heresy.⁴{{Fn|8}}

The short-story '''Hell in a Bottle''' by Simon Jowet mentions a '''Primarch Rubinek''' of the [[Iron Hearts]] chapter.^{{Fn|12 }} Primarch Rubineck is not mentioned anywhere else. Some authors seem to occasionally confuse the [[Chapter Master]]s with the Primarchs and Rubinek was most likely such a case.^{{Fn|13}}

As Horus lay in coma inside the Davinite temple after being wounded by [[Eugen Temba]], [[Erebus]] gave him visions that showed him events from various points in time. In one of these experiences, Horus found himself in the geno-vault where he was created, and looked down upon the genetor-tanks containing the infant Primarchs. At one point he stops before tank '''XI''' and reflects upon the "untapped glories that lay within, knowing they would never come to pass". This refers to one of the unknown Primarchs. Later on, Horus' anger takes control and he smashes his fist upon tank XI, damaging it. Shortly after, a vortex swoops up all the genetor-tanks and scatters them across the galaxy.^{{Fn|14}}

The truth of this vision is unclear; it should be noted that the whole experience was orchestrated by the Chaos powers, in other words Horus saw what the chaos gods wanted him to see.^{{Fn|14}}

When [[Dante]] asks the [[Blood Angels]]' successor chapters for men to bring the Blood Angels back to full strength, having suffered heavy casualties during [[Arkio]]´s heresy, [[Seth]], chapter master of the [[Flesh Tearers]], makes a counter to this demand: disband the Blood Angels and spread them amongst the successors. When [[Orloc]] (chapter master of the [[Blood Drinkers]]) protests that there is no way a First Founding Chapter can end like this, Seth retorts that, actually, it has happened before. ^{{Fn|16}}

*The Lost Primarchs were erased from Imperial records at least 43 years prior to the events of Isstvan V, as only eighteen Legions are referenced during the events at [[Monarchia]]. This could be a precursor to the Horus Heresy, the belligerents serving the chaos gods. However, this seems unlikely as the primarchs would be aware of chaos, yet are easily seduced by it.^{{Fn|18}}*Its implied that the Emperor personally cast aside the two lost Primarchs: "I fear the Emperor will break the Word Bearers - and break me. We would be cast alongside the brothers we no longer speak of."¹⁹{{Fn|18b}}*Throughout the remainder of the Great Crusade, the remaining Primarchs were oathed not to even talk about the lost Primarchs.²⁰{{Fn|18c}}*The lost Primarchs/Legions are referred to as 'the forgotten and the purged'. This could simply be a way of describing traitors, or they are references to the individual legions (i.e.-one legion "the forgotten" and the other "the purged")²⁰{{Fn|18c}}*[[Magnus the Red]] confirms that the Emperor personally purged the two lost Primarchs/Legions from history.²¹{{Fn|18d}}*During the vision of the [[Gal Vorbak]], the eleventh Primarch is referenced as still being innocent and pure prior to the scattering of the Primarchs. This implies that the eleventh Primarch either becomes corrupted or is guilty of some degree of transgression against the Emperor/Imperium, or both.²²{{Fn|18e}}*Both lost Legions are said to have been expunged from Imperial records for 'good reason'. They are said to have in some way acted shamefully.²³{{Fn|18f}}*A rumour is revealed that could explain what ultimately became of the II and XI Legions. Around the time that the II and XI Legions were expunged from Imperial records, the Ultramarines Legion swelled in Astartes numbers to eclipse all other Legions. It could merely be a rumour, or it could actually be the case that the II and XI Legion's Astartes were inducted into the XIII Legion after they were officially expunged from Imperial records. If this were true, it would suggest that the legionnaires of the II and/or the XI haven't committed any offence; the crime lies with the primarch, and possibly a minority of the legion. This rumour however still doesn't explain what actually happened to the II and XI Primarchs.²³{{Fn|18f}}

*In the novel [[Deliverance Lost (Novel)|Deliverance Lost]], in [[Corax|Corax's]] reflection on his first meeting with with the [[Emperor of Mankind|Emperor]], the Emperor mentions that there are seventeen other Primarchs. When Corax asks how this can be possible, as he is the nineteenth, the Emperor's face becomes "bleak, filled with deep sorrow", and he says that it is "... a conversation for another day."²⁵ {{Fn|20}} This indicates that the II and XI Legions were already lost, and possibly expunged, by the time that Corax was reunited with the Emperor. It also suggests that they were lost in the earlier years of the Crusade, as the Emperor mentions that most of the other Primarchs had already been discovered by the time that he came to [[Deliverance|Lycaeus]].

*In the novel [[The Outcast Dead (Novel)|The Outcast Dead]], [[Evander Gregoras]], the [[Master of the Cryptaesthesians]], states that the "Wolves will be loosed again", this time to make an example of [[Magnus]] who used forbidden powers to contact the [[Emperor]]. Assuming that the [[Space Wolves]] are meant, this implies that there are people apart from the Emperor and the [[Primarchs]] who are aware of what had happened and confirms the role of the Space Wolves as an instrument to sanction other legions and Primarchs.{{CFn|2621}}

*In the novel [[A Thousand Sons (Novel)|A Thousand Sons]], during the Triumph of Ullanor Crusade, [[Magnus the Red]] mentions missing Primarchs,in the conversation with [[Mortarion]]. [[Magnus]] "Brother," said Magnus,ignoring Mortarion's words. "A great day is it not? Nine sons of the Emperor gathered together on one world, such a thing has not happened since..." [[Mortarion]] "I know well when it was,Magnus," said Mortarion, his voice robust and resolute in contrast to his pallid features. "And the Emperor forbade us to speak of it again. Do you disobey that command?"{{CFn|2722}}

*In the novel [[Fear to Tread (Novel)|Fear to Tread]], [[Horus]] witnessed [[Sanguinius]] struggling then killing one of his Blood Angel legionnary, [[Alotros]]. When Horus asked Sanguinius the reason he murdered one of his sons, The Angel first refused to answer his brother. Insisting, Horus finally had his answer: Sanguinius transmitted a genetic flaw to his Blood Angels, known as the [[Red Thirst]], which turns a legionnary into a mindless killer, leaving him no other choice than killing Alotros. When Horus asked Sanguinius why he never talked about that with his Primarch brothers and, above all, why he never asked for help from their creator, the [[Emperor]], Sanguinius replied he feared the most radical solution his father could propose: "You know the reason! [...] I will not be responsible for the erasure of the Blood Angels from Imperial history. I will not have a third empty plinth beneath the roof of the Hegemon as my Legion’s only memorial!’{{CFn|2823}}
