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.

De-Suspendi is an overall joker. He loves to try making other dragons laugh, or cheer them up as they have sorrow. Suspendi hates it when other creatures make fun of him for his overall hovering appearance. He'd be self conscious every time he's around dragons, which is why he thinks making jokes is his best option. If he isn't up to it, Suspendi will more likely float away to high trees and hide. His closest dragon friends say he might as well be the unfortunate flier.
