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.

Liftrenna is very relaxed. She sees no point in rushing, when you can simply float around gently. She has mixed popularity among the dragons, some liking her relaxation, and wanting to learn more about how to become extremely relaxed, and others detesting her relaxation, or "laziness" as they spitefully call it. But Liftrenna pays no attention to these insults. They quite literally "bounce" off her.
