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.

Allegra is happy and carefree. She rarely even notices danger, and her mate Adalward is often seen rescuing her from yet another predicament that she has gotten herself into. Angana quickly managed to find out that Allegra is a willing partner for her many schemes, mainly due to the fact that she doesn't realize how dangerous they are, and the two of them are often seen together, plotting. Allegra is always surprised when she finds herself in trouble again, and she never understands how it could've happened.
