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.

Cream Puff War is a trickster of a dragon. She has a very keen dislike of humans. One stole her very first egg, and Cream never fully recovered. She left her clan and moved deep into the Endless Ruins of the Past, where few mortals tread. She has some aptitude with illusion spells and uses these to make the Ruins even more foreboding. For instance, she likes to appear as a more ferocious dragon than a balloon dragon, and she's particularly good at using existing shadows to suggest fearsome forms. Rumor has it that she can capture someone's mind and leave them stuck in the memories of their past. It's unsure whether this is truth or just a rumor she put out to deter visitors.
