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.

Hanyu Furude mysteriously appeared here not long ago.  She seems to have unusual "bumps" on her head; however, they are gray which is expected of a stone dragon.  Like many other dragons she is truly something to be afraid of when aggravated.  Oddly, this dragon seems to repeat the same things on a daily basis.  Despite Hanyu's lethargy, Rika Furude is constantly seen with her, and they seem to share some kind of bond.
