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.

Ah, a true prince among dragons.  Prince William comes from a cave hidden in the depths of a forest so remote from humans that it wasn't until he was several hundred years old before he had the pleasure of eating a delicious human dragon snatcher.  Even then, this was not a vicious attack.  As a princely dragon, William was honorably protecting the lair from human dragon snatchers, as they try to kill young dragons and collect their teeth for trinkets.
