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.

As a dragon that has a craving for a nebula that has its stars glowing similar to flames, she loves to see flames on Earth as well. If there are fires close to her, she will always notice them by being high in the sky or getting news from other dragons running from the fire. Keycylanaxa loves to see fires but feels that she is responsible for finding or getting informed about the fire, so she asks nearby dragons who can control water or wind for help. She watches the process of burning and destroying and then sees the flames that devour everything just become nothing. Something so destructive that one would think would live forever with that much energy sucked from everything in its path, but with enough effort even such devastation can be calmed down and erased completely. But Keycylanaxa feels a little sad that the fire needs to be stopped. Maybe it just doesn't know any better. Maybe it is just afraid of dying and takes life from others because of its fear of getting put out.
