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.

Stonedrag is not a king, yet had all the potential to be. He thrills others because of his growling voice, which he doesn't use on purpose. He's a rather big dragon even for his kind. However, he's okay that he's not the king of Foresttrotters, as Toki, being a shy and often indecisive White dragon, often consults him for help. He also sometimes serves as his bodyguard. Their friendship started long before either of their wings grew in, and none of the dragons forgot this. Stonedrag has a lot of knowledge on martial arts and won't hesitate using his claws or creating an earthquake if something threatens him or the king. Of course, only the king can stop him, and the others have to save themselves. Despite being seemingly a thick-skinned barbarian, Stonedrag is much more sensitive than one might think. He has a weird addiction to bananas and orchestral concerts. Stonedrag often smiles over something he likes, especially when he eats too many bananas that Jungleclimbers sometimes sell.
