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.

In the caves, Sir Jailbreak is known as a scalawag, a scoundrel, and a scrimper. He is always looking for the best deal, and the unwary often find he has pulled the wool down over their eyes and duped them. The gossipmongers like to say the only sophisticated thing about him is his royal bloodline; he is the firstborn son of Lord Bounce and Lady Justice, who rule over Credo Lair. Sir Jailbreak works for his father as an overseer and has used his connections to amass an admirable hoard for himself. Unfortunately, his wealth is a source of constant stress for the young dragon. Sir Jailbreak is so worried about being tricked out of his fortune that he finds a new hiding place for it at least twice a week. Quite like a squirrel, he sometimes forgets where he has hidden his stash. It is for this reason that the residents of Credo Lair sometimes stumble across a small fortune hidden among the rocks or in the underground hot springs.
