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.

Jimmoh's name means 'Summer' in another language. When she was a hatchling, she was captive of a black dragon named Edash who used to bring her food. When old enough, she escaped. Her rough childhood never bothered her. She found a master and friends, and is a very sweet-tempered dragon; a very good friend. She loves to clear fog each morning that may have gathered around the trees and also looking after eggs like a foster mother.
