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.

Giga Drill Breaker, or Giga as most of the others call her, seems unfazed by her ridiculous name, of origin long warped by an endless succession of chinese whispers. Being a stone dragon, she usually can't be bothered to drag her massive weight around, so she can generally be found curled up in a corner, musing to herself. She is a source of great inner wisdom to those who ask for it, and her mellow nature ingratiates her with the stoic Phedora. She is quite partial to Incendius' antics.
