A great tentacled beast lived at the bottom of the great ravine that separates northlands from south. In ages past it would ravage the land, devouring all, until a warrior-priest organized a system of sacrificial virgins every decade to placate it. But the people grew angry at this practice. The warrior-priest and his followers were chased away.
A decade has now passed since the last sacrifice, and the rumbles of the pit-beast can once more be heard deep in the pit. This time strange people have emerged from the pit before the coming of the beast, herding great slithering tentacles before them. You have come in the interest of reward, curiosity, and perhaps aid to deal with these strange people of the pit.
