Fafnir

A high-class dark dragon possessed of great intelligence and a fickle personality, the source of which is said to be impossible for Humans to understand. The dark dragons stole the secrets of the gods, with Fafnir achieving full comprehension of the dark arts. Legend speaks of a magician drinking Fafnir's blood in search of similar comprehension, and learning a hundred tongues and a thousand spells as a result.
