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.

Bran Chrisial was born in the winter, and people that do not know him well think that his personality matches the period he was born in perfectly: cold and distant. Bran however only looks this way on the outside, as on the inside he is actually very uncertain about himself. This uncertainty makes him reluctant to communicate with other dragons, which gave him his reputation as an emotionless dragon. A young female dragon, also a seasonal dragon born in winter, managed to break through Bran's defenses however and although the two differ in age quite a bit, Frosta seems to bring up the gentle and soft side in the iceblue male dragon, which finally made the other dragons change their opinion about Bran.
