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.

Emerald Immortality is often thought to be immortal by humans. This is not true. His owner called him that in the "will always be remembered" sense of immortality. He's loud and obnoxious, often making other dragons cringe. Emerald Immortality loves showing off to dragon lovers, and talking about how beautiful he looks, though he looks like any other earth dragon. Some dragon researchers appreciate his love of showing off, but others are less tolerant. Some villagers even attack him with spears, which he just shrugs off as jealousy. He is extremely sensitive to dirt and will wash himself nonstop until his scales shine. He will murder anyone that so much as smudges his scales without hesitation. Emerald Immortality may seem extremely powerful, but he is very pathetic when it comes to dirt, often begging other dragons to stay away from him when they aren't as clean as him.
