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.

Udatia was found as an egg in a cave, levitating. Jazzi chased and chased the egg, but the egg kept floating away, no matter what Jazzi did. One day, Udatia's egg began to shake and she emerged. She climbed on Jazzi's arm and Jazzi took her back to her cave. To this day, Jazzi and Udatia still play tag as they did when Jazzi chased Udatia's egg. Udatia is the undefeated champ of tag in Jazzi's cave, because no one else can float the way she can. Her name, though slightly altered, means "levitating" in Hindi.
