Khaynites

From Introduction: The undisputed masters of First One society, the Khaynites are both a race and a priesthood, an entire species dedicated to the worship of the grotesque god of blood, Khayne. Depraved and sadistic, the Khaynites are also brilliant and mighty, and to defy their will invites tortures beyond imagining. The Khaynites have long desired a return to glory in Exodus, and after two thousand years of exile, they are prepared to fight with all their formidable resources to effect that return.
