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.

ShadowWalkerSecret and her twin brother SilentShadowSeeker are Shadow Walker Dragons. Their eggs hatched at the exact same time, and they have been inseparable ever since. Even though they fight sometimes, SilentShadowSeeker can't stay mad at her brother for very long. She is the bravest twin, her brother is a little more hesitant. ShadowWalkerSecret is usually in the shadows but still engaged in conversations with multiple friends, even gossiping with them about other dragons in the cave. But her brother tends to just stay next to her and not talk unless asked a question by one of ShadowWalkerSecret's friends.
