Green Dragons are also sometimes called “earth” dragons. They usually live deep within caves, and have power over the earth. They are capable of launching boulders at high speeds, and can cause earthquakes by slamming down onto the ground.

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.

Koi sama is a troublesome dragon. He doesn't get along with most dragons but he doesn't try to be a problem. Usually he spends his days in the cave by the nest and rests there, hiding from all. When  he's needed he always shows up but rarely speaks. He fancies Akkimi, the outcast of the herd but never builds enough confidence to go up to her and bond.
