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.

Omichli Cosmos is a mute dragon. Prematurely hatched because of an earthquake, she was born not being able to make a sound. Her lack of a voice inspired her to become completely silent in all that she could do. She flew to dark mountains and jungles, seeking to learn stealth and evasion tactics from some of the sneakiest dragons in the world. She trained with these dragons for many long years, until she was able to out-sneak her masters. Her muteness seemed to give her the edge in stealth; this, combined with her very faint patterns which aid in camouflage, helped her become one of the most efficient dragon spies of her time. Her mate is Soupouno, with whom she developed a very unique way of communicating.
