Dark Shadows

Spooky demon cat who was brought back to the real world only to be forced into a contract they didn't even agree to in the first place. They are stuck haunting a poor kitten who doesn't even deserve any of it, but they can't exactly stop being around her because of the contract they were bound by. The only potential way to break the contract would be to either kill the poor kitten, or for a StarClan Cat to somehow grab and smash the necklace that Dark Shadows is holding around their neck.
