Revenant

Revenants are undead creatures meant to serve a purpose dictated by either the Raven Queen or some other divine/magical individual who gave them life in a body based on the corporeal form their soul once inhabited. They are not necessarily bound by the will of the person or deity who resurrected them, though; they have free will and are completely autonomous. A revenant's body's features are mostly similar to the previous life's, but the skin and hair color are ashy shades of gray or white or black and instead of finger/toenails they sometimes gain claws like talons. They don't always have a vulnerability to religion-based or radiant powers and are not inherently evil-aligned undead entities. They're weird and can be interesting characters depending on who's playing them and what the player's concept for the character is.
