Inquisitor Lord Hieronymo Drake is dead. As is the sector, the Macharian Inquisition is in turmoil — but one Inquisitor has taken on the challenge of uniting them in a Conclave. Beyond countless heretics, demonic influences, and evil xenos, lurks a threat that, if left unchecked, could consume the entire sector. Can the Inquisitors and the shepherds of the conclave put aside their dark wars and work together to eliminate this threat before it endangers the entire Imperium?
