Menzoberra the Kinless, a powerful priestess of Lolth, founded the city that bears her name in −3917 DR. By the wishes of Lady Lolth, she led seven drow families into the Northdark from the southerly drow holdings of Great Bhaerynden. The drow families, having no immediate external enemy, fell to attacking and undermining one another, as was drow nature, to the greater glory of their evil goddess, who so loved chaos. Only fifty years after the city's founding, in −3864 DR, a great and terrible battle between the two most powerful Houses, House Nasadra and House S'sril, occurred. This battle led to the exile of House Nasadra (which later founded the city of Ched Nasad, and was the First House until the city's recent destruction) and to the rise of House Baenre as the First House of Menzoberranzan.
