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.

Sliver Stone is a Stone dragon. He doesn't like to be near other dragons at all. He is very shiny. The scroll-keeper thinks that when Sliver Stone was a hatchling, he must have eaten rocks containing silver which made him look silvery. He is a medium sized dragon, a little small for a stone dragon, though. Sliver Stone will sleep a lot. He will wake up when he is hungry, but he will usaully only stay awake for a few hours.Sliver Stone was named Sliver Stone instead of Silver Stone becuase of his wings.The one time he has extended his wings with the scroll-keeper watching him,His wings each had one long, thin sliver in each of them. The scroll-keeper isn't sure if this was normal, so he was named Sliver Stone instead of Silver Stone.
