Although most of the Shadowfell in the Barony of the Golden Wolf has been subjugated by the Obsidian Wolf, there is one notable power than chose to join him on nearly equal footing. The exact nature of the Skindancers is unknown, even whether they are a separate race is undetermined.
Skindancers are excellent combatants, utilizing a flowing combat style and runic magic. Their weapons tend to be incredibly sharp small blades, often on the ends of wires. After fights, they use these blades to remove the skin from their victims, particularly the faces. These faces are tanned and sewn together into the garments that cover the Skindancers.
Having killed a Skindancer, our heroes discovered nothing under the skins.
