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.

Towards winter, as the days get shorter, Moony Boy spends more time outside his den, slinking in the dark. When he finds a suitable victim, he sneaks up to them and goes, "BOO!" Ideally, his target will launch into the air as he gleefully runs off. Repeat as many times as desired. Although a few people have scary reactions to his spooking them, with some even vowing revenge, the activity is too much fun to stop. Moony Boy is a fast runner and has the ability to sink into the shadows, so he's safe. His record number of "boo"s for a single day is 396, which occurred one especially eventful Halloween and ALMOST convinced him that there's such thing as too much of a good thing. That night, he must've yelled boo at every dragon and human who was outside in a ten-kilometer radius. When he woke up the next morning, his muscles ached, he felt woozy, his bag of mana was depleted, and all he wanted to do was lie in nest all day to recover. "Man," he thought, "Maybe I should lay off the 'boo's".
