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.

Killier is still a hatchling at heart. She is an excellent mother, constantly hovering over the eggs and hatchlings but her favourite pastime is playing. Unfortunately, she often becomes a tad too immersed in the play and ends up causing earthquakes. Fortunately, a solution was reached when she first took the hatchlings on a trip outside the cave and now conducts all of her playing sessions in the valley below. The game she plays most is throwing rocks at trees while the hatchlings bet on which tree will fall first. When she's not playing around Killier is often found in the sun, basking and gathering energy for the next session with the hatchlings.
