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.

Diamond Pebble is the leader of the cave. It is unknown why he is the leader since he was not the first to mature. He is respected by all the other dragons mostly because he is an earth dragon, but Oak Bough secretly thinks he should be the leader. Diamond Pebble cares for all the dragons and hatchlings and eggs and some say this why he is the leader of the cave.
