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.

Knight of Snow is the first dragon to grow under her mistress' care. She is also the first mother in her clan. She mothered three dragons, Knight of Glaciers, Ciel de Talia, and a third one who died. Ciel de Talia and the third dragon, both white dragons, were separated from her since birth, making her cry. Fortunately Knight of Glaciers grew up with his mother.

She guards her whole clan and makes sure nobody would be hurt or will leave the Blu Clan. Unfortunately one of the hatchlings of her own kind left, and even if it wasn't directly related to her, she cried again because she took the hatchling as an own child.

Knight of Snow is now aided by the other knights, especially Knight of Freeze and Knight of Protection, the parents of the hatchling who left.
