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.

Manafest is best friends with Splinter's and wind the seasonal dragon. She says she is ten times more like a ninja than any of the other dragons and even Splinter's and wind, due to her ability to seemingly disappear and reappear at will. The Human agrees to this because not even she can see Manafest when she wants to be completely hidden.

She is training under a daydream dragon called Cirrus White to become a Guardian of heart, an elite dragon that is in charge of the defense of the Human and Hatchlings.
