From the introduction:
Classic tabletop roleplaying games often see the adventurers striding boldly across the countryside, tracking evil to its lair and vanquishing it in the name of wealth and glory, protecting the world and its people for another day.
Dark fantasy tells a different story, and the world of Grim Hollow invites participants to imagine narratives tinged with shadow, fear, and the drama of despair.
In the world of Etharis, the roles are reversed from a typical high-fantasy campaign. It is the good who cower in their fragile bastions of civilization while evil stalks freely across the land. Adventurers skulk furtively through the shadows, always aware of the danger that follows closely behind them—or the danger lurking within their bodies and souls. Welcome to Grim Hollow!
