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.

Like SilverStar, Treasure is very aware of his amazing looks. Unlike the Silver, however, he keeps the boasting to a level that does show off his magnificence without seeming too arrogant.

His glittering crystals aren't his only great trait, though. For a dragon of his weight and size, Treasure knows how to move elegantly and quickly enough to be a good hunter. This has also won him the affection of Guardian, the herd's main Protector, whom he mostly gifts his food to along with a lot of flattery. All in all, Sora was not very surprised to find Guardian holding an egg after less than a day.
