You will have counted my chronicles and found eighteen primarchs. You are owed an accounting of the other two. This is all of it that exists.
Struck from the Rolls
Once, the Emperor forged twenty sons from aspects of his own being. Two of them — the Second and the Eleventh — were struck from the rolls of honour long before the Warmaster’s rebellion, each consumed by a catastrophe of such fell scope that few ever knew its full dimensions. It is forbidden to speak of them, by the censure of the Master of Mankind Himself. Every legionary of every Legion, loyal or traitor, knew the rumours; none knew the truth. When Corax, newly found, asked why his father spoke of seventeen brothers when he remembered being the nineteenth, the Emperor’s face grew bleak, and he said only: that is a conversation for another day.
What Became of Their Legions
Of their legionaries, I can give you one sentence of substance: they were too valuable a resource to discard, and were, in Malcador’s careful phrase, attuned to new circumstances. The rumour that the Ultramarines swelled great by absorbing them, my old master dismissed as insipid conjecture — and note, as I did, that he dismissed the conjecture and not the question. Rogal Dorn, they say, carried the bleak memory of one such disaster deep in his hearts. He never once spoke of it in my hearing.
Why This Page Stays Empty
I keep two empty alcoves in this archive, and I will not invent banners to fill them. Whoever they were, whatever they did or failed to do, their erasure was thorough beyond anything else the Imperium has ever managed — which tells you, if you think on it, precisely how much it mattered. Some doors my lord sealed with his own hand. I am his archivist, not his judge.
Two names are missing from this scriptorium. If you ever find them written anywhere, burn the page and walk away. That is not superstition. It is the only direct order the Sigillite ever gave me twice.
Questions from the Archive
Who were the Second and Eleventh Primarchs?
Unknown — and forbidden. Their records were expunged by the Emperor’s own censure, struck from the rolls of honour long before the Horus Heresy, each consumed by a catastrophe few ever knew the dimensions of.
Why were the Lost Primarchs erased?
The truth is deliberately unrecorded. The novels’ sources say only that it is forbidden to speak of them by the Emperor’s censure, and that the truth of their losses is forever shrouded and unknowable.
What happened to the legionaries of the lost Legions?
They were ‘attuned to new circumstances’, in Malcador’s words — too valuable to discard. The rumour that the Ultramarines absorbed them is recorded only as unverified conjecture.
