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 lives under the happy delusion that he is pregnant. The other dragons in his clan have often reminded him that is both male and a reptile and thus not equipped for pregnancy, but he turns strangely deaf at their explanations. He can often be found talking to the ball of helium that he calls his 'baby bump'. Exasperated, the other dragons have given up on lecturing him on why he cannot be pregnant, and he now lives in his own happy little world where he is the proud soon-to-be mother of many young hatchlings.
