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.

Momsem is a young carefree dragon who can never hold one thing down for long and has an unusual and untamable thirst for change. Being one of the few naturally nocturnal dragons in the cave she shuns the company of her father Stelliphae and Night Glory drake Bournville, and instead flies high into the night skies, almost invisible in the darkness as her shimmering patterns blend into the background. She is gentle and solitary character who prefers to face the world alone and feels nobody truly understands her. She has no true friends or enemies and has a bond with no other dragon, severed from social life by her own will.
