Blutsauger ( German: Blood-sucker)

These vampire bat-like Wesen are the mythological basis for vampires. They stay normal during the day, but when day turns to night they begin to Woge. Their nose becomes larger, the ears become pointed and recede, and small teeth emerge from the mouth. They feed by draining their victims of blood. A famous Blutsauger was Vlad Dracula.

Varulv ( German ( and swedish) : werewolf)

Like the Blutsauger, they stay normal during the day. When Woged, they, unlike Blutbaden, they gain a more dire wolf-like appearance, rather than humanoid. Silver is fatal to them. It will petrify their blood.
