After their horrid, soul-destroying fight on the world of Sarkeath, Attelus and his comrades have earned one lead; a name: Inquisitor Soloston of the Ordo Malleus. Soon, he's tracked to the backwater shrine world of Quoranda. But something froths beneath the surface of the oh so puritanical world. Something destined to drown the entire sector in a sea of agony and decay.

Three years after Secret War. Attelus and the other survivors are sent to investigate the war torn world of Sarkeath. With Attelus' hallowed heroes, the men of the Velrosian 1st fighting on the surface, it's personal. Especially when their leader, General Tathe had ordered a successful Exterminatus months before. Is this yet another scheme of their shadowy foe? Or a dead end?
