The black clouds that hid the sky over the northern lands dissipated, and the orcs of the defeated Kingdom of Many Arrows fled to their caves. Drizzt and his friends think about the future: about family, about new adventures, about a new home. The drow of Menzoberranzan have founded a city in the depths of Gauntlgrym, a recently discovered ancient dwarven settlement that Bruenor Warhammer is determined to reconquer. But before the dark elves can repel the attack of the dwarves, they will have to fight each other, as well as an army of demons, whom they, contrary to common sense, summoned to their own city. Gromph Baenre, the powerful archmage of Menzoberranzan, deceived by the Demonic Spider Queen, risks losing his high position, supernatural abilities and even his sanity in a desperate attempt to seize power. Chaos reigns in the capital of the dark elves.
