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.

Riliu lived among gray dragons in her owner's cave under the rule of King Arenag and Queen Android, doing her job for the cave without hesitation. The only payment she ever asked for working so hard was simply "a male."

Since the beginning of this desire, Riliu has lost track of her children and their parents, merely continuing her life working and doing as she wished. Eventually, quite a few of the male dragons she had been with had gotten angry with her constant mate-switching, and quietly killed her in the night for her unfaithfulness.
