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.

Many of the other dragons make fun of Floating's ungainliness. The younger dragons especially think it is fun to call him chubby.

Nonetheless, he is very optimistic and tries to see the best in everyone and everything. Sometimes, however, he likes to knock young hatchlings off the upper branches of trees in the region, laughing as they fall to their deaths as their wings are too undeveloped to save them.
