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 ferocious and dangerous dragon, Gaalsien's family line has been filled with deadly and hate-filled dragons who care only about battling and making others follow them. He brutally mauled the tamer, which led her to be rescued and cared for by S'jet and Ryukari. He is a dangerous beast that will attack without hesitation or the slightest provocation. Even though the tamer helped him, he turned around and attacked. He is truly a mad and powerful beast.
