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.

Rhythm has never been the type of dragon to want a mate. Sure, he's fallen in love and never found any, but he dismisses it all as silliness from his hatchling years. However, those hatchling years were what brought him to this situation that he is in now. As a young dragon, he had the smallest and darkest crystals of all of his family. Because of that, he ran away from the scolding and teasing of his relatives. He now lives with the mismatched band of dragons, and still refuses to take a mate even with his bright crystals.
