Evanna

Lady Evanna is a sorceress and hates being called a witch. She can only talk to the dead if they are in the Lake of Souls. She is Desmond Tiny's daughter, Hibernius Tall's sister and she gave Larten Crepsley his scar. Normally, she wears ropes instead of clothing.

She is half vampire, and the only one born a vampire. She was the only one because vampires are sterile, but evolved from wolves. Desmond Tiny mixed vampire and wolf blood to create Evanna. She is the only Vampire able to carry a child. At the end of the books, she is said to have been pregnant with twins; one Vancha March's, and one Gannen Harst's.

Evanna has the ability to breed faces of vampires onto the backs of frogs, and the faces are actually the only way to see an image of a vampire (since vampires can't be photographed).
