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.

Named after the star she observed, she mimicked the Eta Carinae Supernova and watches it closely every evening for the tiniest detail she may have missed. Her owner is rather fond of Nebula dragons and allowed her to mature without subjecting her to their experiments. She tries to help the malnourished dragons (when she can't see her star) as best she can without going against her owner's wishes as they experiment on eggs and hatchlings.
