Upyr

The Upyr is a Russian vampire that rises from the dead. They hunt down entire families starting with the children and working up to the adults. They come from the corpse of a witch or from someone who committed suicide. They can also be created if a person or animal walks over the grave of someone recently deceased, causing them to drain their life force to reanimate themselves.
