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.

This dragon has no idea what her name should be and has been nicknamed "Nameless Galaxy" by her clan. Nameless Galaxy is interested in stars, as most Nebula dragons are. She counts every star on her wings, the wings of her offspring, and the wings of her half-children, and their children, etc. She is certain that this is a normal habit, having counted the 12,652 stars all across her body multiple times, as well as her child's body, which is a larger number of 20,109 stars. This includes not only the bright stars, but the dim stars, and the distant stars, and every single star that she could find. The clan speculates that Nameless Galaxy is crazy, and hasn't thought of a name for herself, because she's too busy trying to count all of the stars in the sky.
