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.

Bubblepuff is a very happy and easily excitable dragon. She is naive and clumsy and makes one laugh like there is no tomorrow. Bubblepuff grew very slowly as a hatchling and her power was never great. She disappointed her trainer and was labeled as replaceable and was abandoned. But she remains positive and never holds a grudge. Today she lives with Aquenia, a dragon trainer. Bubblepuff met her as a child, she was her first dragon and they grew up together.
