Perhaps among the most venerated of dragon breeds is the Zyumorph, a breed whose selfless heroism and strong moral compass are nearly unparalleled by other dragons. Zyumorphs have an innate urge to fend off wrongdoing, and as such, are often sought after in times of peril. Although they are independently quite capable fighters, it is said that their true might is not unlocked until all six Zyumorphs are brought together in times of great duress.

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.

Jacuzzi lives in a brine pool deep below the ocean's surface, somewhere off the coast. People know which coast because there's a dense field of paintings he's created over his unimaginably long life. They just don't know where his pool is because the poisonous gas and extremely salty water kill creatures that get near enough, so it's not worth the risk to find out. Whenever Jacuzzi rises out of the water and swims to shore, he is covered with a purple-blue coating, likely a dense magical shield that protects him from the deadly water. Sometimes, he comes up because someone needs help, but more often, it's to paint. His favorite subjects are the contents of his brine pool—many of the ones he's floated midair for display depict crystals, jagged yellow rock, and pickled animals. Viewers can only assume that the pool really looks like what Jacuzzi paints, since they can't see for themselves.
