Upierczi
Viesczy
These vampires have origin in Poland and Russia and is also called Viesczy. They have a sting under the tongue instead of the fangs. They are active from noon to midnight and can only be destroyed by burning. When burned, the body will burst, giving rise to hundreds of small, disgusting animals, such as maggots, rats, and so forth.
If any of these creatures escape then the Upierczi's spirit will escape too and will return to seek revenge.
