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.

KeY Winter is one of Iceglacier101's cute dragons, all of whom are special and unique in their own way, but they still manage to be friends with each other. Unlike the other Keys, Winter is shy and humble and as if he's below the other's rank. He tends to be quiet all the time, But when winter comes, he suddenly has more energy than the rest as if having a sugar rush, and when playing outside, others seems to lose always to him. When comes to winter games, he rules the snow.
