Listening to the words of the Chaos Space Marine Morchan, Governor Kadi Aren led Spheris into rebellion against the Imperium. This resulted in the deaths of millions and brought Spheris to the attention of the Flesh Tearers Chapter. Seeking to kill the head of the rebellion, they sent the Librarian Balthiel to the planet, who single-handedly killed the Governor and his bodyguards inside his compound. With the Governor's death, the rebellion was left leaderless and the Flesh Tearers moved to bring the planet back into compliance.
