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.

Pegmatite is an extremely energetic Stone Dragon.  She has been observed to change position as many as eight times a day and even won a local ten meter race (taking less than five hours to make it across the finish line).  Despite her name she prefers finer grained rocks and most of her movement is executed in pursuit of different mineral delicacies.  Since she was abandoned as a hatchling her food preferences may be indicative of where she hatched and spent her early life, but this is just speculation.
