Draugr

A Kindred whose Humanity has fallen to 0. The word "draugr" comes from the Old Norse term for a reanimated corpse that viciously stalks and kills its living relations. Draugr are non-sentient. They do not reason or think; cannot even speak. A draugr follows a simple plan. It hunts, kills, eats, sleeps and the following night it does it all over again. Vampires who have reached this stage have forever and irretrieavbly succumbed to their Beasts. The Man within them is gone for good. Due to the threat they pose to the Masquerade, when a Kindred becomes draugr, Princes frequently have no choice but to call down Blood Hunts upon their heads.
