Graveyard Diggers

Description
Graveyard Diggers, also called Bone Eaters or Bone Wearers, depending on your knowledge of their actual existence, are tar dragons, often coming in the shape of a wolf, though mimicking other species of animal isn't uncommon. Their bodies are made of tar and held together by magic, and are often misconstrued as vicious beasts who kill the living to wear their bones, when in reality, they take the bones of the already deceased and "repurpose" them, be it by sticking them to their tar-covered bodies as armor or sucking the nutrition from their marrow. They are generally passive creatures, but recently, due to habitat/environmental changes and humans hunting them for their resources, they are becoming more aggressive and territorial. They are not malicious creatures like some other dragons, but are humble and share food with each other when in groups. They are fairly large dragons, usually about 20' when standing upright (which they rarely do, only to scare off threats) but about 24 feet long, not including the tail. Juveniles are smaller, obviously, and recently they've not been sighted as fully mature adults nearly as much.
