63 nobles, over 2,600 drow soldiers, 700 slaves
The first drow house of Menzoberranzan, and has been for as long as anyone in the city can remember. It is the oldest (around 5,000 years old), strongest, and most prestigious house in the city. The compound also houses the largest cathedral of Lolth in the city, which is large enough to seat all 2,600 soldiers maintained in the compound; this is the mainstay of the Baenre army, but rumours suggest that during a crisis, the First House could double this number of troops. Triel Baenre is the current matron mother.
