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.

Abandoned, Nebula had nothing to hatch for and nothing to do. Just waiting there, waiting to die. That was the only thing on her mind when she was moved from one cave, and another, for no reason. Then Tmi found her, and then she began to wonder even more. But when others kept saying "You can go!", and "Hatchies Rock!", she hatched, and learned how wonderful her world was.

   Since she likes the night, she has a hard time keeping up with the other dragons. She couldn't make any friends. She was desperate, and was kind to a vampire dragon, The Aggressive Night. They both had no friends, so they became friends.
