Storm Dragons are the masters of the skies. They are excellent fliers and land only to rest and eat. In addition, they have full control of the weather. They are very hot-tempered and easily angered. They will attack any human that bothers them, conjuring strong winds and dangerous lightning.

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.

Fuii is not a very practical dragon. Most of his day is spent conjuring rings of dark clouds and darting through them, rather than hunting with the other males. When one of the more down-to-earth, so to speak, males such as Anjyorasu attempts to get him to stop his 'goofing around' and help with the hunting, he gets extremely angry and may even fire off a bolt of lightning if bothered enough. Has a soft spot for one particular female, Jyori, and tries often to impress her... to no avail.
