Carmilla

Carmilla is actually an anagram of the character's real name. In reality, carmilla is Mircalla, the Countess Karnstein, who died many years ago. She had a lover and her early death plunged him into inconsolable grief. He moved her ruins to try and protect her, but she was then haunted by a demon who turned her into a vampire after her death. Her victims are young ladies. She visits them at night in the form of a huge black cat and leaves two fang marks in their chests. As a rule, her victims become ill and die, sometimes in days or weeks. She is finally killed in her grave with the help of General Spielsdorf and the Baron Vordenburg.
