Royal Blue dragons are a nocturnal breed who prefer to live high in the mountains near slow-moving water that reflects the night sky. Although quite capable of defending themselves, they are peaceful by nature and will avoid a fight whenever possible.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

COD refuses to do anything until he is properly "wound up". He claims to be in fact a complicated mechanical contraception powered by magics and steam that regularly needs small sacrifices of precious metal to keep the magic working flawlessly. As long as he regularly gets gold or silver coins put into his mouth (which he later spits out and adds to his hoard) he is the perfect dragon companion and does everything that is asked of him without discussion or protest.
