Strigoi
The Strigoi is a form of vampiric monster from Romanian myth. The term Strigoi can be used as a general term for any evil entity, and it comes from the Italian word “strega” meaning Witch. They often shapeshift into night birds like owls. Over time they transformed from witch vampires to an undead form of vampire.
