Night's Black Agents: Dracula Dossier
Baron de Vil
Little is known of the Baron de Vil other than he was encountered conducting mysterious business at Carfax Abbey, discussing a matter of some importance with The Abbot. There was a theory that the Dark Stranger was, a the least, a vampire, perhaps even Dracula.
Later it was determined that Baron de Vil was, in fact, Dracula, during a chance encounter in Prague.
