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.

Professor Jahred Margul loves sunbathing and recreational picnics. And the only perfect season to do those things is the Farlands Summer with its hot, sunny weather and the low humidity. So, he modified a Seasonal Summer Dragon to be able to absorb the energy of the sun, and control the humidity of the air around him. And thus was born Summersun.

His magical traits activate during the Summer season of Farlands. He sunbathes during the day, and releases the energy during the night, along with his ability to control the humidity of the evening air. Though harmless and with a small area of effect, the released sun's energy is enough for the professor to continue his sunbathing and picnic schedule around his laboratory with Summersun lazily floats in the air yawning and waiting for the sunrise to repeat the process again.
