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.

Froze loves to observe the night sky as much as the next Nebula, maybe even a bit more. She isn't content to just watch the sparkling galaxy during the night hours, she wants to be able to do so all the time, independent from time of day or season. So over the course of the years she has worked tirelessly, first with the Ice dragons and later with the Magis to construct a system of caves, caverns, and light wells made from ice, all focused on catching as much of the nocturnal celestial display as possible and preserving them flawlessly in time through magic. So in her labyrinth of ice it's possible to watch a perfectly preserved midsummer night's midnight sky during the middle of the day on Yuletide, making her very popular among her brethren, especially those whose favourite constellation can only be seen partway through the year.
