From amidst the growing anarchy and prophecies of a final ending rise those who would deny the last darkness and, in so doing, seize victory for themselves. Greatest amongst these is Abaddon the Despoiler. Forging an infernal pact with a dread new ally, he unleashes the mighty Arks of Omen and their rapacious Balefleets upon the Imperium Sanctus and the Imperium Nihilus alike.

Striking at world after world, the Arks ignite fresh conflagrations of war wherever their shadows fall. Humans, aliens, and even Abaddon's heretical rivals fight back against these nightmare war fleets wherever they can - but there is a darker and more insidious purpose to the attacks of the Arks of Omen, and time is not their ally...
