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.

Hrixa has long ago decided that guarding the borders of the clan on the ethereal plane was not something she was very good at. Since this duty has long since been the honourable task the Shadow Walkers have set for themselves, this—to a certain degree—makes her an outsider among her brethren. She always felt more at home among the students of Delirium's Academy and has stayed there gladly even after the basic hatchling education.

Hrixa spends her days and nights—and of course the potent twilight hours—studying illusions.

The magic of smoke and mirrors, the art of deceiving the onlooker, is often mistaken as a mere charlatanry. But Hrixa knows that every illusion has a more tangible reflection in the higher planes, that a well placed mirror can catch a shadow, and that smoke can be made to poison the soul of an enemy. So she focusses her studies on possible ways to apply the spells to the protection and betterment of the clan, contributing to the Walkers' everlasting guard.
