In the northern regions of Greece there lives a particularly barbaric species of vampire known as a vrukólaka, although the vrukólaka was originally a Slavic vampire. Created when the Devil possesses a corpse, the vrukólaka then rises from its grave and begins to systematically kill first its relatives before moving on to people outside of its family tree. To destroy the vrukólaka, the body must be exhumed and a priest perform an exorcism over the corpse. If this method proves to be unsuccessful, then the body must be cut up into little pieces and burned down to ash.
