Geode Dragons are closely related to Stone dragons. They are covered in a hard stone-like material as well as beautiful crystal. Their wings are entirely useless for flight, but they help attract mates. The dragons with the most brilliant and colorful crystals are more likely to mate.

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.

Celestial Stone was born from an egg found in the highest place of a rocky formation about half a mile from a small volcano. As he grew up and he learnt of this story, he began to fantasize about being the offspring of some heavenly breed of dragon and that he was thus born from a 'celestial stone'. He was the only Geode Dragon in the clan for a long time, during which he pestered the other dragons whenever possible about him being so special. He knows now that he is just one more of his kind, but he is still being ridiculed by the older dragons who had to cope up with his pestering in the old days.
