Hungarian demons, these monsters are said to be the evil spirits of long dead humans that now stalk graveyards and travel around causing destruction and plagues. In their true forms, they resemble hideous humanoids mounted atop two headed dragons. They feed on peoples' souls and give the living diseases, but can be appeased through use of blood sacrifice rituals. Obviously this is not recommended, and like any other demons they can be hurt using salt or iron.
