Kallius Subsector

The Kallius Subsector was an Imperial subsector whose constituent worlds rose in rebellion during the late 40th millennium. Its precise coordinates were not recorded.

The insurrection drew in Chaos Space Marines from a number of warbands, who took command of rebel populations and fleets across the subsector. One account identified the Black Legion among the Chaos forces involved, though this was not confirmed elsewhere.

The Angels Numinous Chapter was dispatched to suppress the uprising but was overwhelmed by the scale of the rebellion.
