Editing The Voidwatcher (section)

===Post-Heresy===

After the Heresy was completed the Voidwatcher retired to his flagship and took to the stars with his legion in search of more arcane secrets to discover and use. After a few centuries of this wandering alone on the edges of civilized space or the Eye of Terror the Voidwatcher decided it was time for him to venture into the uncharted void of space in search of arcane lore. He left behind his Vates to create their own covens among the stars and compete and quarrel amongst themselves as their namesake had once done on Ostium. He did this in order to ensure constant progression and improvement amongst the remains of his legion. With this final decree he boarded the smallest combat worthy vessel he possessed and took it and it's crew into the void beyond the galactic rim. He has not been seen or heard of since.

Or, at least, that's what the Augurs believe. 

In reality the Voidwatcher's ultimate plan came to a head in a dual with the Bloodseer, captain of the Haruspex and the original commander of the Black Augurs before the discovery of the Primarch. Bloodseer had long silently held the Voidwatcher in contempt for what he had done to the Legion. The brutalizing of the Bloodseer's men during the Decimation had just been the beginning, the Voidwatcher's teachings had rendered the legion a squabbling band of sorcerers and wizards. No longer were they the united fighting force Bloodseer had led at the outset of the Crusade. He had always been suspicious of the Voidwatcher, after the Heresy this suspicion only increased as the Voidwatcher began to become even more distant from his sons. The Primarch had taken to locking himself away in the deepest recesses of his libraries and laboratories, endlessly toiling on some hidden project.

The Bloodseer endeavored, finally, to find out what his gene-sire was planning. In the end, after enormous difficulty and a number of rather unlikely alliances he was able to piece together what was  being planned. The Voidwatcher was cultivating his legion, twisting them with the intention of a great reaping, a harvest of souls that would completely eradicate the Black Augurs. Everything he had done was a lead up to this. The Decimation was never just to make them more potent psykers, it was to make their souls richer in the energies the Voidwatcher sought, he had incited his legion to fight amongst themselves to weed out the week. Everything the All-father had done under the pre-tense of "enlightening" his sons was a ruse, he had been fattening them and preparing them like lambs to the slaughter. The High Vate's study had led him to believe that this sorcerous holocaust would result in his ascension to godhood, and while the evidence seemed to add up to the Bloodseer he could not allow his Legion to be destroyed. 

Bloodseer confronted the All-Father on board a small starship he had been using as a mobile and private laboratory. Their massive duel left all of the Bloodseer's allies dead, the grand ritual incomplete, and the Voidwatcher cast into the Warp maelstrom he had conjured to draw essence from. The Master of the Haruspex returned to his legion with the story that the Voidwatcher had simply ventured off into the dark corners of the galaxy. He could not have them believe their All-Father would betray them, it would result in civil war and the end of the legion despite his efforts. So he held the secret of what truly happened that day from his legion.
