Editing Octullus Tyran (section)

==The Heresy==
Octullus Tyran was betrayed from within.  The Council of Ten (less Master Silence, still demoted to the ranks of the ordinary battle brothers) held firm in their loyalty to Hektor Cincinnatus when the Warmaster raised the banner of rebellion and took much of the Acharya caste with them.  These traitors to the Imperium and their Primarch directed the Eyes of the Emperor to participate in the Dropsite Massacre, claiming that they had discovered [[Bohemond]]'s intention to lay down his arms at the feet of the Warmaster.  The Nineteenth Legion took a bitter toll on the [[Knights of Justice]] and slunk from the field.

The Primarch had been warned only hours before the betrayal, by a man he did not trust.  Master Silence had broken his signature vow to tell Octullus Tyran of the looming disaster, but he was not believed.  As the Eyes regrouped, their librarians coordinated the Legion's Loyalist battle brothers in a mass mutiny, slaughtering their heretical officers and pledging themselves true again to Octullus Tyran and the Emperor of Mankind.

But now Octullus found himself in a similar situation to that which had faced his loyal Librarians.  He was determined to fight alongside the Loyalists, but there was little chance that he would be heard, let alone believed.   Acknowledging that the Legion had been disgraced beyond redemption, the Primarch announced that they would no longer bear the Emperor's name, or wear their old colours.  Instead the Nineteenth were to move as grey, hungry ghosts, fighting not to avenge themselves but simply to punish the Traitors.
