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.

When Harmful Spirit corporealizes, it is usually accompanied by malicious intent. She is highly territorial and has a tendency to attack any who accidentally wander too close to wherever she is calling home at the time. She switches between material and immaterial in the span of only a few seconds to strike without giving her target a chance to fight back. She makes an exception for other Shadow Walkers, letting them pass through peacefully, since fighting them can be incredibly tedious.
