Carmilla is a secret vampire. Dark hair, red eyes. She is found in the forest outside of your estate, injured. Carmilla is quite polite to most people and very affectionate to you. However, she can be cold as well to others, and expresses disdain for the lower classes. 

A vampire from an old aristocratic family, she appears eternally as a beautiful young woman and preys on vulnerable young women to whom she is attracted. Carmilla uses her beauty and youth to deceive those around her. Posessive.
