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.

Making Music is named for her ability for making music (of course). When she hits against something, it makes a short high sound. But when it hits harder, the sound gets lower. It takes about 6 minutes for her to float up to a high tree because she always wants to stop and hit something to make a sound. Since she isn't good with children, she stays away form the clan's babies. If a strong wind tries to blow her away, she will wrap her tail around the nearest, tall object, and stay there until the storm is over.
