In the heart of a frigid northern winter, Rayden Valkyrie takes refuge in the lands of the Sarvan people when a mounted column of Attun warriors is seen passing along the outskirts of their territory heading west.
Far from their steppe domain in the east, the Attun warriors are journeying into a remote, unpopulated wilderness, drawing great alarm from the Sarvans about their purpose. Learning of the situation, Rayden joins with a band of warriors from the area's villages to investigate.
Following the tracks of the Attun warriors, they are led to the base of an enormous, ancient burial mound, where the trail vanishes abruptly. A mystery looms, and Rayden seeks to discover the nature of the burial mound and the reason why the Attuns have traveled so far from their homelands to enter it.
Darkness Enthroned is a stand-alone adventure that is part of the Rayden Valkyrie Tales.
