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.

Yasei inherited her mother's personality, making her probably the kindest and friendliest Gray Dragon you'll ever have the fortune to meet. She does have the same love of the clouds like any Gray Dragon and like her father is quite the wild tomboy. As a hatchling she has been quite the troublemaker, and being an adult now, but still a child at heart, didn't change a thing about that (exept maybe for the amount of damage she does now).
