Seasonal Dragons take on the characteristics of the season during which they are born. Thus, eggs that are laid in spring match the pink flowers and green buds of spring, and those that are laid in the summer grow to depict the bright green of the forest trees and the yellow of the sun. Eggs laid in autumn display the bright colors of leaves falling from trees, and those that are laid during winter take on the appearance of the icy snow.

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.

Glau is an elegant, very controlled dancer. Her every move speaks of discipline and her training enables her to make the most complex moves seem effortless. While she could have easily followed a career as a professional dancer, she decided against it and joined the clan's defense forces being the only Summer member besides Buffy. The two have a friendly rivalry going with their similar, almost dance-like fighting moves but if the situation demands it they work together like a perfect fighting machine.
