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.

Poundage is a whimsical, changeable green who has a curiosity about humans and their behaviors. She messes with people in small towns (she sometimes calls them "play areas") by changing the height of the ground in different places while leaving the level ground on which structures rest intact. This results in odd mounds and steps around the outdoor parts of the settlement that people have to climb over or go around, although if they remained in their homes the whole day, they wouldn't notice. She lets this go on and watches the reactions for a quarter-day or so. With few exceptions, the transformations are not permanent, though: Poundage always reverts the surfaces to their prior levels (to the best of her memory), since she knows that one of the humans' reactions may be "deep indignation", and she'd rather they not go after her. She's also become attached to some of her play areas, though she claims that that's not true and is purely playing with them for her own amusement.
