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.

Dual-screen Ghost sells furniture out of a small shop she shares with her partner, Meditangian. She is the muscle of their operation, using her innate magic to make furniture as intangible as she is to help move large pieces into the shop or to a customer's weyr without needing to worry about walls or doorways. There have been a few times when she got a large piece to where it was to go only to discover it wouldn't fit; at least once the room was remodelled around the furniture to get it to fit. She has a scar on her shoulder from when she had just started out and had yet to master phasing out objects. She had been bringing a grandfather clock into a spitfire's home when she accidentally let it slip back into the physical world. It was tall and she smashed it into the roof. She had done so well getting the clock into the weyr that everyone watching was surprised when she broke the glass ceiling.
