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.

Despite his name, Pisces' zodiac sign is Virgo and his temperament is unlike that of Fighting Fefnir (which he is named after). Pisces enjoys quietly watching the change of seasons, summer obviously being his favorite. He doesn't speak much unless spoken to and even then his answers are brief. His demeanor has a calming effect on most other dragons who interact with him, so it's not unusual for a group of dragons to gather around him and sit and enjoy nature.
