Vohlen is a young woman who left her family's house to become a doctor. Presently living in the Eastern-European village of Dhaldot, she has the ability to turn the living into "bone people", animated skeletons who continue existing until the bones decay. Vohlen is a ghoul. In exchange for her services, she is given the flesh of those she turns into bone people. Her two older siblings disagree with her intentions of helping people, believing that humans are just food. Vohlen was previously the lover of Klaus Kleiberg, the brother of her friend, Amanda.
