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.

A pudgy, friendly old sample of a balloon, this dragon can often be seen giving human children and hatchlings 'balloon rides' across the clear park skies. When not indulging the squeaking youngsters or working at his job as a cargo hauler, he can often be found snoozing in the sunlight outside his companion's university. His companion is a human female who raised him from a baby, and while she is sometimes exasperated with the jolly, chubby creature, the two love each other a great deal and do almost everything together.
