assistant
Hunched forward on two immense legs, the ancient bone wyvern towers at a height of over twenty feet, rotting foreclaws drawn and ready to lash outwards at a moment's notice. Its massive dragon-like skull is partially visable beneath a cloak of rotting flesh that precariously clings to its enormous skeletal body, covered in an array of jagged cracks and scratches. Twin tongues of deep purple flame rest in the hollows of its eye sockets, churning in a tempest of unfocused hatred. Gigantic skeletal wings arc outward from its spine-lined back to shadow its rotting form, and both wings are partially draped in a shifting cloak of rotting flesh.
