“Vâlvă (plural vâlve) is a female spirit mentioned in Romanian folklore. Akin to the Iele, the Vâlve are believed to walk over the hilltops at night, and are subdivided into Vâlve Albe ("White Vâlve"), who are considered beneficial, and Vâlve Negre ("Black Vâlve" or "Dark Vâlve"), who are considered evil. In certain contexts, they are believed to have human form (especially when they came to protect villages from a storm). They may also appear under various guises, such as shadows or black cats. They also have the ability to shapeshift.”
