From the back of the box:
"The halls of Khazad-dûm once rang with the pounding hammers and singing voices of Durin's Folk, the greatest of the Dwarven clans. But that wsa long ago, before the Dwarves, in their avaricious hunt for new veins of mithril, awakened the Balrog who lay slumbering beneath the Misty Mountains.
Today, the halls of what is now known as Moria echo with the sounds of the Shadow - the tramping of booted Orc-feet and the cracks of the Balrog's fiery whip. This massive underground complex, which extends for many miles beneath the mountains, is filled with treasures untold and horrors unnamed. Only the most determined of heroes - or the most desperate - dare brave its endless halls and deeps.
