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.

Named after a coarse, dark, indigenous rock, Gabbro spends his time in the depths of his cave, content to study the rocks and determine which seem the most appealing to eat. While he is not an active creature, prone to sleeping for long periods of time and then stirring only to eat, Gabbro finds himself playing babysitter to hatchlings as they clamber over and around him. Even though the majority of them have razor-sharp claws, it does nothing to his pebbly hide, and he rather enjoys watching the younger dragons.
