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.

Trevya is the second-born of Trobi and Evia. Like his sister Shi Ling, he has taken to heart their lessons of rock and earth lore and joined in the task of expanding and excavating the mixed adoptive hatchling cave. He noticed the Pink Dragon Zort's courtship of his older sister without remark, although in his heart he was happy for her. He looks forward to the expected extensions of their family and is open to finding love himself one day.
