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.

Oriokoe has always thought Stone-Cold's breed is awesome and cool but she's a little dissapointed all of her rock dragons turned out to be male. Stone-Cold can't move fast but can deal with powerful blows and has a strong defense. Stone-Cold is lazy and likes to soak up the sun, which is why Oriokoe's other dragon don't like to get to close to him. Stone-Cold got his name because he reminds Oriokoe of the wresler Stone Cold.
