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.

An old tower in an almost dead forest serves as a hiding place for the clan's most deadly magical treasures. The power that radiates from these artefacts is potent enough to blanket the entire area in permanent darkness, thus causing the surrounding plant life to die as it is starved of sunlight.  

Vercingetorix serves as the guardian of this tower, his excellent night vision allowing him to see through the shadows. Many heroes and other adventures often try to conquer the tower in search for its riches; often doing battle with Vercingetorix on the tower's apex when he descends upon them, the glowing stars in his wings the only source of light.
