Archmage opens the Homecoming trilogy by turning back toward Menzoberranzan itself, where Gromph Baenre, the city's archmage, wrestles with the political undercurrents and old magic that will eventually draw Drizzt Do'Urden back to the city he fled decades before. R.A. Salvatore uses the opening volume to rebuild the stakes of Menzoberranzan's drow society before Drizzt re-enters it. It sets the stage for a true homecoming after multiple series spent almost entirely on the surface.
