Nachtzhrer
The nachtzhrer is a vampire from the region of Germany and the Baltic coasts. It is said to lie in its coffin devouring its own burial shroud, which causes a progressive wasting that brings illness to its relatives.
At night, in the form of a pig, it prowls diabolically and attempts to climb the bell towers of churches. If it succeeds, it makes the bells ring: the sound is fatal — those who hear it will die.
To destroy the nachtzhrer, one must locate it in its grave by following the trail of grunts that emanate from it as it eats its shroud, and once found, it must be exhumed, a coin placed in its mouth, and its head severed with an axe. The head and body must then be buried in separate places.
