A combination wilderness/dungeon module, first searching for then exploring the temple of Tharizdun. Tharizdun is long gone from the place, so there's no epic final fight. Rather, a mysterious Black Cyst waits at the bottom of the dungeon. The encounter with it is almost scripted, having no hazard except for careless/foolish players. Contains several monsters from the Fiend Folio. Loosely follows Lost Caverns of Tsojcanth. TSR 9065

As a member of a bold party of adventurers, you and your associates have trekked far into what seems to be a whole underworld of subterranean tunnels -- arteries connecting endless caves and caverns which honeycomb the foundations of the lands beneath the sun. Your expedition has dogged the heels of the Dark Elves who caused great woe and then fled underground. This module can be played alone, as the conclusion to module D1 & D2: "Descent into the Depths of the Earth," or as the third module in a series that forms a special extended adventure (G1-G3: "Against the Giants"; D1-D2: "Descent into the Depths"; and Q1: "Queen of the Demonweb Pits").

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.
