Shadow Walkers are a strange breed that possess the ability to slip between the planes of reality, becoming immaterial. This allows them to hide in the shadows, either hunting from the concealment of near invisibility or evading enemies. Though they become corporeal to mate or to eat, they spend most of the rest of their lives walking in the shadows. Shadow Walkers are wary creatures, though on dark autumn evenings when the leaves fall to swirl in the chill, rain damp air, they may be seen drifting out from the shadows.

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.

His name means "No Substance".

This specimen, like others of his breed, spends most of his time immaterial, wandering between the shadows of other dragons and visitors. In the growing colony of dragons whose names are listed on this scroll, Naas Loras functions much like a watchman, keeping an eye over those who rest during the night and tracking newcomers until they settle in. While he won't often materialize in the company of others, if one is aware of his presence and was to ask him a question directly, he may deign to appear long enough to answer. He gets along surprisingly well with Uvet'nau, likely because he, too, is often on a different plane of existence.
