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.

As the daughter of a Baron and a member of the noble house of Black, this dragon naturally earned the title "Lady", although there is not much lady-like in her appearance or behaviour. Lazily she floats around, expecting others to bring her food and fulfil her other wishes.

The one thing she does herself is singing, or at least, you could call it singing. It sounds quite like a bagpipe when the dragon pushes the air slowly out of her balloon-like body, modifying the flow of air with her mouth and throat. Not everyone will appreciate such music, but those who do, have to admit that the lady is quite good at it.
