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.

Omega is a rather morbid soul. Ever since she grew old enough to grasp the concept of death, she has spent hours upon hours thinking about possible ways for the Apocalypse to occur. She has studied prophecies and legends and doesn't doubt that the end is "nigh". During the last couple of years she has begun to exchange her theories with a group of human-headed horse creatures living in the woods. They agree with her that the stars foretell a bleak future for them all.
