Editing Azariah Kyras (section)

==The Aurelian crusade==
The Black Legion's invasion into subsector Aurelia finally revealed Kyras' corruption. The Blood Ravens attached to the 4th Company boarded the Judgment of Carrion and discovered evidence left behind by Galan and Kyras, revealing chaotic influence and the pact with Ulkair.

Kyras himself was not present in the subsector during the invasion, instead having sent Captain Apollo Diomedes of the Honor Guard to represent his authority and order a withdrawal from any contact with the Black Legion. However, according to Galan's confession as he lay mortally wounded by the Force Commander, Diomedes himself was not corrupted; only some of the men under his command had been tainted.

Gabriel Angelos and Force Commander Hair Gel disobeyed the Chapter Master's order to withdraw and stayed to defeat the stirring Ulkair on the ruins of Aurelia. The ending of the game states that the "renegade" Blood Ravens plan to depose Kyras, creating a prologue for a Chapter-wide civil war.
