Across the war-torn battlefields of the 41st Millennium, the Imperium of Mankind battles to survive in a galaxy rent asunder by the hellish Great Rift. The God-Emperor's armies fight on countless far-flung worlds against heretics, aliens, and daemons. As the fleets of the Indomitus Crusade rush to relieve thousands of battle-riven planets, unspeakable alien horrors from beyond the borders of the galaxy prey upon the fractured Imperium.

There is no peace among the stars, for in the grim darkness of the far future, there is only war.
