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.

Witty and sarcastic, this young Shadow Walker goes by the name of Shadow Version 27, or simply "Shadow". While generally friendly, he can at times be a bit too blunt or downright degrading towards other dragons, as well as his owner, Kiryu. While both the male Nebula leader- Vector- and the reigning Vampire pair—Aszalia'xai and Akilatrai—have attempted to recruit Shadow for their growing factions, the young dragon merely stays among his own group of friends: few for now, but include an ill-tempered male Vine (Solace in Sleep), a sweet female Golden Wyvern (who happens to be his mate, Taranga), a rebellious female Nebula (SapphireStar), and an insane male Neglected (Fricai).
