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.

Eartheidon Ground-Tremble is a very short-tempered and somewhat violent male dragon. He cannot stand laziness or humor, and is often in a very bad mood. If he is enraged, he will sometimes cause minor earthquakes to occur. He does not actually wish harm upon his fellow residents of the Cave, but he is sometimes seen that way. Eartheidon Ground-Tremble once came across a lost male dragon and nearly attacked him, as he was very close to the Cave. This shows he is protective of his home, and will sometimes even place large rocks by the eggs and hatchlings' nest, so as to protect them from the wind. He is nicknamed the Earth's Anger.
