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.

This dragon has hated 'peeple' ever since she was chased around by needle-wielding children during her early years. Accordingly, she takes out just vengeance on them. This retribution isn't bloody, however, but usually consists of her blowing them over with blasts of air, bouncing her giant squishy body on their heads, or inflating herself in doorways to prevent entry to needle-producing factories... and, of course, punching. The only other sadness than people in her life is that, while her mate is so perfect in every way, he likes the yucky little things. Accordingly, she has punched him on more than one occasion to punish him for this idiocy.
