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.

As a hatchling, Gallifrey would always talk about a strange planet she had seen while searching the skies. A planet that orbited twin suns, with skies of orange and amber, a planet that shone like a jewel. Every night, she would look for this shining world, until one night she could no longer find it, all she could see were asteroids and a brilliant orange nebula that had never been there before. Convinced that it was simply out of sight, the Nebula made her way across the world, always looking for the planet, but only finding clouds of orange and amber dust. Her wings eventually took on the pattern of that nebula, rather than the purples and blues of other known Nebula dragons. While her odd coloration has made her a bit of a novelty whenever she stops for rest, Gallifrey has few friends. At most, she will only have a couple of temporary traveling companions.
