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.

Theresa Mooney is one of the many children of Precioso and Samuel Mooney. She loves her parents so much she decided to stay with them as her brothers and sisters went off to live elsewhere. She saw a star born and knew herself to be very lucky and since then has devoted her life to studying them. She really doesn't talk much with the other dragons as they seem beneath her compared to the stars. Her brothers and sisters do not understand her and therefore do not talk to her at all really. Her parents understand her and know that one day she will find someone who will take her head out from the just the stars and get her to be more into life as well.
