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.

Subluarpok Tla's name means "snow which blows in the wind," though in truth he feels very little wind in his underground home. So much does the winter dragon despise all heat that he has retreated deep underground, far from the light and warmth of the surface. There in his chilly home he survives only on the tiny, sightless fish that live in the freezing water of his subterranean lake, which has left him almost sickly thin. His eyes no longer able to tolerate light, he surfaces only on the coldest and darkest of winter nights when he feasts on whatever animals he can catch. The humans near his home call him a demon, and fill their villages with brightly burning torches on winter nights, hoping the light and heat will ward off the Snow Which Blows With the Bitter Wind.
