Dominus Crusade

The Dominus Crusade was a nearly seven century-long Imperial crusade carried out by the Dominators Space Marine Chapter against the Forces of Chaos around the Eye of Terror.

Background
After the defense of the shrine world Pall'avia, the Dominators began a crusade around the Eye of Terror. The Dominators destroyed many warbands of Chaos worshippers as well as the daemon world Krayub, which was a homeworld to Slaanesh warband of The Unpleased. They had been a thorn in the Dominators' side for thousands of years. They also banished the Daemon Prince of Slaanesh, Nemarah the Excited.
