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.

Bobi is the official hatchling caretaker. She spends her time with the hatchlings floating above them with a watching eye.  Bobi is one of the most caring and gentle dragons there is. She is often called 'Mom' by Going Death and the other dragons. Often tells dragons what to do and what not to do. Stone Jackson protects the hatchlings cave, so is it so odd that Bobi and Stone spend a lot of time together. When the hatchlings go to sleep she curls up near Stone Jackson's head and falls asleep too.
