Vourdulak
From Tardis Wiki, the free Doctor Who reference
The Vourdulak was a vampire, or siren, described in Russian folklore, who took on the form of a beautiful young woman. In the stories, she was "[really] old and ugly", but fed on innocent victims, draining their energy to become youthful again.
Locals believed that a Vourdulak roamed the Novrosk Peninsula. Sofia Barinska blamed the Spaceship Remotes' victims' unexplained deaths on the mythical Vourdulak. (PROSE: The Deviant Strain [+]Loading...["The Deviant Strain (novel)"])
