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.

AirKisser was the first member of a growing dragons' clan. He was supposed to command it, but his slow body motion seemed to be also reflected in his way of thinking. As soon as the elders of his clan realized that, they proclaimed Yliah their leader. That made Air a little jealous of her, but as soon as he saw how hard a leader could work, he turned his attention to things he cherished most, like eating! Now he doesn't exactly support Yliah's leadership, but he respects her job.
