Osyluth

Osyluth, sometimes known as bone devils, are tall, emaciated fiends with dried skin stretched so tight as to outline and emphasize every bone in their body. They have a skull-like head and a bony scorpion like tail and they exude a stench of decay. An osyluth stands about 9 feet tall and weighs roughly 500 pounds. Osyluths often serve as the informers and police of the Nine Hells, monitoring and reporting on the activities of other devils.
