Acheron Parthenopaeus is a member of the Atlantean pantheon, one of the last of the Chthonians, and the leader of the Dark-Hunters. His reputation for vagueness and never answering any personal questions is legendary. Acheron first appears in New Orleans in Night Pleasures to aid Kyrian of Thrace and Amanda Devereaux in regaining Kyrian's soul so that Kyrian could vanquish Desiderius.
