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.

Grass Stone has a quick temper and is not afraid to express her opposition through violent earthquakes. Because of this, Mother Moon and her do not have a good relationship, she has killed eggs in the past on account of her earthquakes, and also runs the risk of killing adult dragons. Grass Stone does not care, to her the risk is worth the reward. She is an impatient dragon and wants the eggs to grow up fast like she did, so she chooses to cause these deadly quakes.
