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.

Ascudgamyln's name means 'fists of steel' for good reason. Ascudgamyln is very good at combat among mountains and rocky cliffs, where she simply shuts her eyes and freezes into place. When an enemy comes close, she springs, smashing her huge stony tail over their heads. But she does not revel in the love of war; instead, she enjoys to peacefully meditate by ponds and forests, letting her conscious become one with nature. Shamroc (a Green), Dappling Leaves, Snowflayk, Wynter Sky (Autumn and Winter Seasonals), and Dannflorr (a Dark Green) all share her love of nature, and sit together often for a meal by the stream running close to the Towa camp. Ascudgamyln is not active very often; therefore, some do not find it appealing to talk to her for very long, as she may fall asleep half way through the conversation.
