A hero dispatched by their deity into the Dungeons of Doom with a single mission: recover the Amulet of Yendor. The Amulet was stolen by the malevolent god Moloch, who has hidden it somewhere in the fiery depths below. The dungeon is vast, the enemies are formidable, and the magical artifacts waiting to be found along the way are the only edge available. Success or death — nothing else comes out of the dungeon.
