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.

Rock Solid Snake was so named because, after hatching, she laid down next to the cave wall and didn't move for a week. Her owner didn't notice the limbs and, being an amateur dragon owner, assumed that she was limbless and wrote down the first name that came to mind when seeing a "solid rock snake". The name stuck even after she got up and shambled over to the other side of the cave.

She often hides against the sides of her cave, trying not to be noticed. Because she is incredibly large and doesn't seem to be able to breathe without loud grumbling noises, it goes without saying that she is not very good at it.

Objects brought in and left around her long enough tend to disappear. Though it is increasingly obvious that she is the one stealing them, it is unknown where she keeps them, as they are not on her and her hoard has never been found. Interestingly, she has never been caught in the act.
