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.

The strong, silent type, Concrete Angel tends to give off a bad first impression, with others thinking of her as cold and distant. Her actual looks don't help dispel this image, given her intimidating size. However, she craves attention. A-chana and her 'family' of dragons have always been there for her, but outside of their circle, Angel feels alone. Her one true desire in the world is to be loved -- she'll even accept someone that only pretends to care, just for the false feeling of being wanted. Even with such a tough outer appearance, Angel is as gentle as they come.
