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.

Named after the Vanir god in Norse mythology, this whimsical balloon dragon can often be seen floating high above the shoreline of any land, riding the thermals and updrafts. He does not stay in one place for long so he has no territory but when he does come across other dragons he engages in light conversations with them, mostly about the weather. Nyjoror is an expert on the winds, especially costal ones since he traverses them so often, he also enjoys singing tunes that he overhears human sailors singing.
