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.

When he was a maturing hatchling, Ikuraka went to a festival attended by several clans. Though he did not socialize with others as much as his older siblings did, he happened to meet a particularly charming female Nebula dragon. He was too shy to speak much with her, and never saw her again after the event. Nevertheless, he remembered the pattern of markings on her wings, and made painstaking efforts to find the nebula she chose to observe. When he found it in the sky, Ikuraka decided to follow it instead of the previous nebula he'd watched. He hopes that in doing so he will continue to remember his friend, and hopefully find her again someday.
