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.

Homulily is one of the more mysterious dragons inside the pack with her powers unknown even to Night Artemis. She does not enjoy the other dragon's presence, with the exception of Octaveia, whom she is childhood friends with. Even so, she does not stay near the other Shadow Walker, leaving after a short conversation.

As with her personality, Homulily's powers are unknown and powerful enough to be feared. She is known to use her powers of slipping through reality so she can temporarily rewrite it, a power very much unknown to others of her species. Yet when she rewrites the past from a day ago, or stops time for even a few minutes, it will drain her of energy, forcing Homulily to fall into a coma-like state to recover for a week. Hence why the powers she possess are used, in fear that other dragons will murder her when unprotected.

Octaveia has a tendency to get annoyed by Homulily's ambiguous attitude. Despite being friends, the two tend to fight just turn invisible on each other.
