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.

In the dark of the night, forests are covered with the snores of wild dragons, and the growls of those who are hunting. But it is rumoured, that somewhere, there is a forest so silent that it is empty of even the chirps of crickets and creeks of trees waving in the wind. The forest is deserted of all signs of life, and the trees are nothing more than dead sticks wedged in the ground. It is rumoured, that it is there, where Slender lives. It is said that his wings remain as black as they were when he was hatched, as he has never seen the sky, and his skin is as white as a ghost. Rumour says that he flies without moving his wings, and that none who has ever seen him has lived more than the time it takes for them to scribble what they saw on a piece of paper, which then drifts on the winds for miles until a lone dragon finds them. So hatchlings are warned never to wander off at night, never to follow the winds without a clue where they would lead, and never to trust silence.
