Purge of Ninen 5

The Purge of Ninen 5 was an Imperial castigation campaign conducted by the unforgiving Dominators Space Marine Chapter against the vile Tzeentchian Chaos Warband, The Changed, upon the Imperial world of Ninen 5. The subsequent campaign would last for five whole decades, at the cost of nearly a third of the Chapter's battle-brothers.

Background
The Purge of Ninen 5 was an ambush orchestrated by the Tzeentchian Chaos lord Morek the Changed. The Dominators suffered heavy losses, but they destroyed the warband of The Changed. Around 300 battle-brothers died. Ninen 5 was later purged for 50 Terran years, before being considered pure by Dominator's standards of purity.
