Vampires

A vampire is a undead creature who survives by consuming the blood of other creatures. In the World of Darkness, it it generally understood that all vampires are the descended from Caine. This mythos is challenged by some, both in the fictional world, and in the real world. The Book of Nod is rumored to tell the story of the creation of vampires, though many characters in canonical sources question the validity and even the existance of that book.
