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.

Pebbled Wing could be considered the laziest dragon in her cave. She often sits in a corner by herself, nibbling on the stone walls. Some dragons fret that she'll eventually cause a cave-in by wearing the walls too thin, but nobody has the nerve to tell her to stop. Pebbled Wing is a massive dragon, and she is rather good at intimidating others. A simple growl will frighten most out of their wits. With this rather useful skill, Pebbled Wing is able to do just about anything she wants, as long as it doesn't require getting up and moving.
