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.

Gimlet Eyes has sharper eyesight than most dragons in her cave. She loves stargazing, and is an agile flier. There is one more thing about her, though. Gimlet can see ghosts. For some reason, Gimlet can see zombies in the day, floating above and long dead hatchlings hanging near the places they died. Gimlet sometimes wishes she couldn't see ghosts, but she is glad she has this power. Gimlet Eyes is extremely good friends with the Shadow Walkers, especially A Ghost of Dragonality and Walking a Path of Shadow.
