The Seventh Black Crusade has arrived. This holy war, later known as the Ghost War, will send countless Chaos fleets sailing out of the Eye of Terror, only to be scattered at random throughout the galaxy by the Warp, sowing the seeds of corruption and decay across the Imperium.
But at this very moment, one fleet has become lost in a Warp storm, disappearing from the galaxy entirely. The Dark Gods guiding them send ripples through the Warp, ultimately driving them toward an unfamiliar star system, the place where their fate awaits: the Koprulu Sector.
A war spanning endless ages and space is about to begin.
