Another text mentions the attempt by a [[Callidus Assassin]] to assassinate a [[Planetary Governor]] named Takis. She used her [[C'tan Phase Weapon|C'tan phase knife]] and attempted to kill Takis, but she failed and her weapon passed straight through him. He knocked her aside and took her weapon and absorbed it into his hand. {{Fn|1b}}.

The Silvae were then introduced to the Imperium and they soon turned to violence, but the Deceiver did not show up to help them. Instead it was dismayed to find them "slipping back to barbarism." It then sent in a Necron force to wipe out all of the Silvae; a few Silvae survived the near-extinction of their race, but there is insufficient genetic variation in these remaining members to perpetuate the species. {{Fn|1g}}

A powerful shard of the Deceiver managed to assume the identity of [[Omegon]] and to trick the scattered war-bands of the [[Alpha Legion]] to follow his orders. The C'tan took shelter in a former necrontyr world in an uncharted area at the center of the galaxy. Such world was cave and riddled with Necron pylons. The Deceiver aimed at using the Alpha Legion to create more pylons to close the [[Cicatrix Maledictum]] and trick humanity into using the "soulforges" as the Necrontyr did before. The Alpha Legion space marine [[Occam]] the Untrue revealed the true identity of the C'tan and engaged him in battle with forces of Alpha Legion and [[Word Bearers]] possessed space marines. The Deceiver was powerful enough to annihilate most of his enemies and to destroy an orbiting Alpha Legion spaceship that had bombarded him. Finally, Occam used a [[tesseract labyrinth]] to imprison the C'tan shard. The Alpha Legion soldier now plans to question the Deceiver about what he knows regarding the current whereabouts of Omegon. {{Fn|2}}
