Known to many as The Vulture, Acherius Erinyes is the leader of the all-Night Lord Raptor Cult known as the Hell-Screamers, and is perhaps the prime personification of what it is to be a Chaos Raptor. Selfish, sadistic, egotistical, and generally considering himself everyone's better, Erinyes and his fellow Raptors stalk the fringes of the galaxy, selling their services to any Chaos Warlord who might give them the opportunity to sate their bloodlust in battle.
