Bloodspeakers

Bloodspeakers or blood mages are evil wizards and priests who have turned to maho or blood magic. Maho corrupts its users, turning them more and more evil, it may even cause them to mutate into monstrous creatures. Blood mages become afflicted with the Taint, a spiritual evil contamination which can be spread by using or being the victim of blood magic or the attacks of some tainted creatures like demons, or Oni.
