Their mission is to locate and retrieve the Fortress of Arrogance, a battle tank that belonged to the legendary Commissar Yarrick, hero of Hades Hive. If Wulfe can keep his mind and men together, and the Imperial forces can retrieve the tank, this will have a huge boost on morale in the Armageddon campaign‚ but are they risking their lives needlessly?

    Into this maelstrom come the Raven Guard 4th Company, the warzone perfectly suited to their lightning-strike methods of combat. Led by Veteran Sergeant Grayvus, their mission is simple - to rescue the planet's last survivors. But in the midst of this nightmare, they receive new orders to locate and destroy a power station. The station is built upon a fault line, and the resulting quake would swallow thousands of tyranids and turn the war in the Imperium's favour. Grayvus and his company must fight their way through genestealers, acid spore mines and a deadly biomorph if they are to succeed and reclaim Idos for the Imperium.
