The rubble-strewn passageway twists and turns, winding ever deeper into the mountain, lower and lower into the bowels of the ancient, forbidding halls of long-dead dwarves. The torchlight flickers, threatening to succumb to the oppressive darkness. Creeping along one striated granite wall, Arikus the warrior moves cautiously toward the great cavern ahead, its sides and walls disappearing into the gloomy distance. Cocking his head to one side to listen, he holds his hand up for a moment, demanding unconditional quiet from from his companions. Then , his arm relaxing in relief, he waves everyone forward and moves into the open. Before him, scattered to the far walls of the enormous cavern, are piles upon piles of glittering treasure - coins from countless kingdoms, sparkling gems, exquisite jewelry, and items of wondrous power - enough for twenty kings' ransoms. Arikus laughs gleefully, thrusting both hands into the nearest cache of coins to let them runs through his fingers. At that moment, a monstrous shadow looms threateningly over him. Looking up, Arikus blanches and stumbles back in horror before the terrible visage of a Great Red Wyrm. The fearsome dragon opens its razor-filled maw and spews forth a gout of white-hot flame, engulfing the hapless warrior.... The ultimate Dungeon Master Fantasy! This is the most deluxe dungeon.

One of the farmers says he found a farm animal crucified and eviscerated in a ritualistic fashion on his front porch.

They must travel to the temple to discover the fate of the men there, and, if possible, elicit their help in destroying the growing heinous power. Pgs. 31-46
