"Marrow"

Katerina Vulkovich was a serial murderess. Not only was she a murderess, bug she was, in life, a fiend. Having grown up during a famine and having witnessed her brother starve to death only to have her parents consume his body and feed his body to her, Katerina was traumatized and twisted. As she got older and beautiful, she became an object of desire. Violation followed. Madness followed that. She became a cannibalistic serial killer with a particular love for the delicacy of bone marrow. Her crimes did not go on long in life, as she became the object of desire for a vampire. Now in undeath, the woman known in the vampire underworld as "Marrow" is far worse than any serial killer that has stalked the world save, perhaps, for the child murdering Silandra.
