Nebula Dragons are nocturnal creatures. With the best eyesight to be found, they are often seen staring into space. Each dragon tends to observe a particular nebula and will eventually change their colors and patterns to match it. As the nebula changes over time, the dragon changes with it. The more intricate the design of the nebula, the better chance an individual has of attracting a mate. It is said that the markings on no two Nebula Dragons will be exactly the same.

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.

Purple or Blue has a large garden of rocks and rough metals. He is a collector of meteorites, and he has methods of figuring out what a real meteorite looks like and is happy to teach other people. He places the meteorites in rows and clusters in his garden and claims that when enough are placed together and left alone for hundreds of years, their magnetic properties will sync and cause the meteorites to meld and grow into much larger masses called asteroids. Once the garden grows into an enormous asteroid field, the iron alloys that have accumulated can be harvested and bent into wearable loops called asteroid belts, which strengthen and invigorate their wearers. People feel that that this explanation about meteorites is incorrect, but none can demonstrate that Purple or Blue is making stuff up. He points out that only he can see deep through space and watch space rocks. At least other knowledgeable dragons can confirm that the garden is indeed populated by real meteorites.
