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.

Butterfly is quite the social butterfly, at least when it comes to the dragonesses. He loves to turn and shine his wings about, dazzling the girls with his beauty and charm. He also has a wonderful voice, which he uses to sing and perform with his friends, Titan Hunter and Tandwiel. The three have always been a killer bunch, surviving on the thrill of a strange thing: every day, these three attempt to murder each other in different crazy and creative methods. Butterfly has a few of his own favorite tactics, such as shining light off of his wings in just the right way to blind one of his fellow performers so that he can leap onto them and fight with tooth and claw. Despite constantly being at each others' throats, the three are the best of friends and love singing together with a passion. Although, on several occasions, even their songs have been interrupted by a burst of flame or a bite to the throat.
