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.

Red Mustang is one of the many racer dragons of EG's Cave. She holds the record for the fastest flight over the Neelix Desert. Because of her fame, she has a huge attraction to Tinsel and Shimmerscale dragons and almost refuses to be seen with a common dragon such as herself. Red Mustang always wants to feel important and loved and claims that she is going to break all of the flight records of the cave. She certainly is striving for nothing less than the best. Many of her rivals live to see her fail because they believe that she is ridiculously arrogant and doesn't deserve the pleasure of feeling better than everyone else.

When she's not racing, however, she enjoys spending time with her close friends. When she is not put under the intense pressure of competition, Red Mustang is extremely social and easygoing, never acting arrogant to any of her friends. In fact, she never even discusses racing outside of competition.
