Prepare to face the perils of the Dark Imperium, a grim and dangerous future plagued by the star-spanning schemes of the ruinous powers...

Cieatrix Maledictum, the Great Rift, has torn the galaxy apart. Time and space have bent and buckled under the warp storm's wrath. Daemons surge into realspace, sowing destruction in their wake. The Imperium of Man has lost contact with untold worlds, and stands on the brink of disaster.

This is a game of intrigue and adventure. This is a game of action and carnage. This is a game about the struggle to stop the doomsday clock from striking midnight for an entire galaxy.
