Trolls Will Be Trolls

From the introduction: Vulture’s Crag sits at the outer edge of civilized lands, looming over a vast plain of tar pits and boiling mud. It’s said Trolls have dwelt in its timeworn caverns for millennia, but they had caused little trouble in recent times. Now, with the arrival of the Troll witch, Stencheye, those troubles have begun anew. Stencheye’s children ravage the holdings of the nearby Lords, devouring cattle, serfs, and men-at-arms. Worse, they have begun looting caravans on the Imperial Road, threatening trade with neighboring lands.
