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.

A rather shy and curious individual, PirateRadioDragon (often just called Pirate or Radio, for short) is the only known dragon that helps out her father DJ Professor K with the relationships of gang-related dragons. In fact, she is rarely seen far away from where he is. Her main job is to just replay music that certain musician dragons gave permission of use for and to keep her eyes peeled for when passersby unknowingly wander into gang dragon territories. When she isn't too busy with patrols and aiding her elderly father, Pirate can be found in the giant library archives, updating various logs about each individual gang dragon that she crossed paths with on a daily basis.
