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.

Hat'n'clogs is a rather goofy dragon who likes to prank others in Nadat's cave by shifting the tunnels around. He's rather fond of shaping the stone into silly faces. Because of this, he's rather popular with the younger dragons in the cave, and tolerated by the adults who wind up having to remap the cave every week or so.

Beneath the playful exterior, though, is a very sharp mind. He is one of the best scouts for the cave, due to his ability to sense vibrations in the earth and analyze what they mean.

He's very fond of his mate, Yoruichi, though sometimes he doesn't quite understand why she puts up with his jokes and fun.
