On the Greek island of Myconi was a species of vampire known as a vroucolaca that was immune to the effects of holy water, prayers, religious processions, and being stabbed with swords. The vampire, left unchecked despite the best attempts of the citizens of Myconi to stop it, fed freely and often. Having no other option other than abandoning their island and moving to the nearby islands of Syra or Tinos, one last attempt was made to destroy the vampire. Its body was found and cremated, and as it burned the demon that possessed the corpse fled, never to return.
