The conflict between the drow of the Underdark and the dwarves of Mithral Hall comes to a head

While Mithral Hall teems with whispers of the war to come, chaos erupts both above and below ground. On the surface of Faerûn, the first signs of the Time of Troubles make themselves known, forcing deities to assume their mortal forms. Beneath them in the Underdark, all but one drow house has lost their magical powers, and Lolth has handed the reins of leadership over to the demon Errtu. But even this turmoil cannot keep the drow from rising up from the black depths of the Underdark to battle the dwarves of Mithral Hall. Bruenor Battlehammer, with Drizzt at his side, will not go down without a fight—but they will have to fight without Wulfgar and Catti-brie at their sides.
