Stone Dragons have a tough outer covering made of a stone-like material. They eat rocks, using the minerals they contain for nourishment and to keep up their stone outer shell. They rarely move, and are the heaviest of all types of dragons. Although they have wings, indicating flight ability, no one has ever seen a stone dragon flying.

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.

Stonarth is a very calm dragon, always easing the mood just by entering a room. Therefore she's also very peaceful and is often the one ending arguments. While her mate, Roanath the Red, blurts out exactly what he wants to say and sometimes hurts others' feelings, Stonarth tends to be more gentle and patches up any wounds that her stubborn mate may have made. They're a good couple with many children, mostly resembling Roanath.
