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.

Ensnared by Stone's time is spent researching flight mechanics and keeping well out of Petra's way. Petra seems to have a...vehement dislike for Stone dragons. As for the flight mechanics, he is determined to fly despite his stone covering. In fact, he is determined in everything he does, and usually succeeds. Past ideas have been posing as a cathedral, sitting perfectly still in the middle of a road, and suddenly charging into a packed town square.
