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.

Venus Rock can be considered the female counterpart of Mighty Boulder. Thus, nothing much is known about her. Other scroll dragons often mistake her for Mighty Boulder or vice versa, but only the scroll master can distinguish the difference between the two. Although she rarely moves, she can sometimes be seen bathing herself in the lake with Tidal Tears swimming around her.
