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.

Spring Kazue has inherited her mother's love for music and her own songs can be heard throughout the territory. However, the spring dragon is very shy and will fall into silence if she thinks anyone is listening to her.

She will spend ages trying to find somewhere where she can sing in peace without interruption, but as the territory expands with each new member of the family; her songs often draw the attention of dragons in other clans. This had lead to a small number of unpleasant conflicts as Kazue's family come to her aid against aggressors. Kazue herself is not much of a fighter, so she is often left on the sidelines whimpering with fright as the black dragons defend the territory.
