A rather elusive magical being Vampires are well known for their predilection for blood, the drinking of which can extend them some protection from sunlight, although they will inevitably burn in time.
Usually native to Eastern Europe (Bulgaria, Romania etc.) many countries have native Vampire populations often varying slightly from area to area - some vampires for example are allergic to roses, while others prefer to eat livers than drink blood.
A Vampire is a dangerous opponent and, despite treaties and laws with vampire groups, fights do still break out. While it is possible for a vampire to transform a wix into a vampire it is a rare occurrence, and has not happened for over three centuries, at the present date. However there have been suggestions that some muggles may have been transformed instead.
