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.

A steady THOOM, THOOM, THOOM can often be heard echoing out from the back of a dust-spewing cave, as this enormous Stone Dragon does his daily routine of push-ups against the granite floor. Obsessed with admiring his own physique, Rockman Solid has come dangerously close to drowning on more than one occasion; peering over the side of deep lakes to try and get a better look at his bulging boulders.
