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.

Muesn was found as an egg. His egg was odd and cold. As a hatchling he avoided the heat created by the other hatchlings and the fires created by the red dragons. He loves spending time freezing anything he can. In general he's a happy-go-lucky dragon who loves spending time with his mate Celebrate To Night. They love doing anything in their power to make the other dragons happy and have a good time.
