Forgotten Realms: Splendors & Shadow
With the abundance of dungeon-plunging adventurers, thrill-seeking nobles, and caravan guards responding to drunken dares, little remains constant for long among the inhabitants of the Dungeon Level, the uppermost level of Undermountain. Roving bands of undead, nomadic orc and goblin tribes, and lone subterranean predators stalk the passages; exiled cults and criminals gather and scheme, slaver bands pass on their way to or from the city above, and various villains and boogeymen lurk throughout the level.
The most reliable reports (and firsthand experience) suggest that the level is mostly populated with various monster tribes – orcs, goblins, gnolls, and ghouls – who are encountered in both large and small groups throughout the level.
Famous landmarks of the Dungeon Level include the Well Room, also known as the Shield Room, where those descending from the taproom of the Yawning Portal arrive; the Hall of Many Pillars, a magic-dead zone near the Well Room; the Hall of Mirrors, a long corridor lined with magical mirrors said to play tricks on passers-by; the Grim Statue, a headless stone statue that arcs lightning at those who pass too close; the Hall of Sleeping Kings, where the plundered skeletons of ancient kings sit eternally in their thrones; the Hall of Three Lords, with its trio of lordly-but-anonymous statues of armored warriors; the Lanceboard Room, a large chamber tiled to resemble a chess board, and enchanted to enforce an ever-shifting set of rules upon those who would pass through; and the Falling Stair, a passage up to the Citadel of the Bloody Hand, enchanted to collapse on those who try to ascend.
