Agriogourouno

(Ah-ghree-oh-GHOO-roo-no)

In Macedonia it is believed that Turkish people who have led very wicked lives and have never eaten pork will become agriogourounos ("wild boars") upon death. As much a were-creature as a vampire, this shape-shifting being is well known for its gluttonous appetite for human blood.
