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.

Peroth Maru is Sylexion's son, and as such he is held with high regard in the cave. He is a sensitive dragon, and prefers to make pretty shapes in the clouds than to whip up a storm. His father has high hopes for him, and spends every free hour trying to teach him the most powerful ways of weather control. His mate, Puku Thuma, is three time his size, and spends little time with him. She chose him as a mate because she only wanted a mate who she could boss around. Like his mother and father, Peroth Maru and his mate have trouble producing viable eggs, although they hope for many children in the future.
