Balloon Dragons are so named because they are filled with a gas that makes them almost lighter than air, similar to balloons. However, they are not prone to bursting, as they are covered in tough skin and can deflate themselves if necessary. In addition, they generally are slow moving. They use their gas bladders to float to the tops of trees, where food is more abundant. They can shift their weight from their backs to their fronts, allowing them to reach leaves and fruit.

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.

Fumble used to be a member of the egg-hunting team, one of the few males to regularly attend the expeditions. Unfortunately, it was found out very quickly that he had a terrible trait, one which would forever leave him nicknamed 'slippy-claws'; he could not manage to keep a firm hold on anything at all. Egg after egg would slip from his wings or back and plummet towards the ground, cracking just as often as they were caught. He would apologize with tears in his eyes after each and every mistake, always truly sorry for what he had done.

Fumble was permanently banned from the egg-hunts after one too many incidents, but was recruited into Criteria's lake-expansion efforts after that; now he's allowed to drop as many objects as he wishes to, as long as they're rocks to help with building up the levee that's under construction. Needless to say, he loves his new job a lot.
