Durin’s Folk long ago came to the great caverns which are now known as Moria, the Black Pit. They delved and built the great realm of Khazad-dûm. Many great and wondrous things were made in Moria, and mithril was discovered there, but a day came when the dwarves delved too deeply and too greedily and awoke the Balrog, Durin’s Bane.

But even long before the Balrog had come to hide in the depths of Moria, the deepest holes and caverns were inhabited by countless evil things. Known now as the Nameless, they have arisen and seek to enslave all who walk the halls of Khazad-dûm. A vile and grotesque creature known as the Mistress of Pestilence commands the Nameless of Moria, who strive to spread her fungal plague to the outside world.

Dark Brotherhood – the level 60, twelve-player, radiance-gated Raid which takes place in Dâr Narbugud – features six raid bosses and a second tier of radiance raid armour.

The Dwarves of Khazad-dûm were known as great craftsmen, with knowledge of seemingly magical arts. Among these were the great Water-works which funneled water from the mountains into the halls of Moria. The chief engine of this process lay within the chambers known as Nalâ-dûm.

After many long years of abandonment, lizards and rock-worms have nested in the works of the great water-wheels, bringing their function to a halt. There are rumours among the dwarves of the Iron Hill Garrison that something far more terrible than lizards dwells also in the halls of Nalâ-dûm. . . .

Players of The Lord of the Rings Online seeking a small fellowship challenge will be pleased with Nalâ-dûm. This instance features three-player content, two bosses, a hard challenge mode, and a radiance armour set piece, as well as a puzzle-based game mechanic.
