The Dark Fey are the offspring of a Demon and a Fey. Dark Fey of different parentage share only two traits, purple eyes and poisonous blood. The fey often consider them to be abominations and seek to kill them at birth.
They often inherit powers from their parents in the way a halfling from other parents might, as a combination or almost entirely from one parent.
It is currently theorized that a strong Phantom-Vampire hybrid may survive the poisonous black blood, although this has only occurred once.
