The forces of Chaos 017M42

The forces of chaos, once a threatening presence in the Perseus Deeps, were almost annihilated prior to the coming of the Great Rift. Many leaders came and went attempting to unite the forces of Chaos, but the gods of the warp lost many key worlds, including Calliden and Bastien, throughout the course of their demise. Now however they are resurgent, and able to strike across the sector. While the traitor legions plan their assault on the beleaguered defenders of the sector, the gods themselves have many new daemon worlds to claim for themselves from those planets sucked into the maw of the Cicatrix Maledictum.

The primary aims of chaos are to claim the "fallen worlds" for their patron god within the warp tear which cuts across the sector, as well as reuniting the scattered remnants of the chaos domain across the sector.
