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.

Grim Green is the original friend of Mr Cirno, Stormy Weather and Dark Shades and lives with them and Amigopen. When he matured, his wings were much smaller than most green dragons and due to his weight, he cannot fly. He can still whack things with his wings as they are also powerful enough to hit people more than 2 miles.
