Saved by the Beast

The Beast of Givaudan is a cursed werewolf that has human hands and feet but coated with fur and the shade of his wolf form. Unable to shift back to human. He was cursed by demonic worshippers and witches. The Beast cannot do anything human like walking in town. He dwells deep in the woods in solitude, but one night he hears chanting. He recognises some voices. The same as what happened to him. He runs there, and sees them chanting and sacrificing a woman during a full moon only he stops it by attacking them.
