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.

There was a clear night with stars and nebula's and galaxies all shining bright. Dragons looking up might see a group of stars and two nebula's moving across the sky at an unusually fast speed. Well, these "stars" and "nebula's" aren't really what they think. They're actually apart of the Nebula dragon Andromera. She likes taking flights at this time especially on nights like this. She is the best night hunter in the cave and will bring back a good haul of deer, rabbits, and other small mammals each night for the dragons of her cave. Then, in the morning hours, she'll fall into a deep sleep until sunset when she'll wake up again and go out. This is what she does on a normal daily basis. She is a survivor and can stand any temperatures. Andromera is brave in battle, attacking enemy camps at night and killing the commanders. When not in battle, Andromera is kind and will help any dragon of her cave.
