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.

Kiirastuli is the oldest male dragon of the clan, and that's why some of the dragons think him as their leader. Kiirastuli knows this and uses the opportunities well and often. He isn't much of the talker and usually answers with a one word or an annoyed growl. Being an seasonal winter dragon, he loves cold places and his main nest is close to snow-covered mountain. He is rarely seen at summer but when winter comes, he settles down at the valley among other dragons and possibly spends time with few of them.
