The conflict between the Underdark and the Mithral Hall comes to a head in the third book of The Legacy of the Drow series and the ninth book in the greater Legend of Drizzt.

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, only one ancient house of the drow retains its arcane power, and Lolth has handed the reins of leadership over to the demon Errtu.

But this turmoil cannot keep the drow from rising up from the black depths of the Underdark to battle the heroes of Mithral Hall, Drizzt Do’Urden and Bruenor Battlehammer. These warriors won’t go down without a fight—but they will have to make their stand without Wulfgar and Catti-brie.

Siege of Darkness is the third book in the Legacy of the Drow series and the ninth book in the Legend of Drizzt series.
