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.

Buoyant Beacon is both slow and plain. She does not move fast in mind or body, and her whole personality is both plain and innocent. She always looks to the good in others and is far to trusting. She is blind to the true nature of the world, but for all her faults she is one of the luckiest dragons in the cave. Her mate is extremely loyal and loves her down to his very core. He dedicates most of his life protecting her from the jibes of the other dragons in the cave that call her ugly and stupid and protecting her from other things. Their relationship is one of the most beautiful things in the whole cave. That is why the other dragons talk about her so, because they are jealous of what she has. She has a relationship that could last forever and that is even stronger then the Love-Caster's spells.
