Humanoids from the Shackles who sold their soul to the Blood Queen and have abandoned everything but cruelty, cannibalism, and warfare. They file their teeth to sharp points and eat their victims while they fight them. Resistant to fear. Gain temp hp when they succeed in drinking blood in combat. Wildly strong and hearty, but unlikely to speak any widely-known language.
