Warhammer 40k Angel Exterminatus

"Perturabo: master of siegecraft, and executioner of Olympia. Long has he lived in the shadow of his more favored primarch brothers, frustrated by the mundane duties which regularly fall to his Legion. When Fulgrim offers him the chance to lead an expedition in search of an ancient and destructive xenos weapon, the Iron Warriors and the Emperor's Children unite and venture deep into the heart of the great warp-rift known only as 'the Eye.' Pursued by a ragged band of survivors from Isstvan V and the revenants of a dead eldar world, they must work quickly if they are to unleash the devastating power of the Angel Exterminatus!"
