Angels of Ecstasy

The Angels of Ecstasy are a Chaos Space Marines warband devoted to the Chaos God Slaanesh who were once the Loyalist Space Marine Chapter called the Sons of Ulthunas. They rebelled against the Imperium of Man during the action remembered as the Ganymethian Betrayal. From there, the Angels of Ecstasy would go on and continue to serve the Lord of Pleasures, Slaanesh.
