The Sargauth Enclave is the name some use for the Netherese outpost on the third level of the Undermountain, but the actual name of this place has been lost over time. It was created c.-800 DR by an order of powerful wizards from Netheril to serve as a safe haven for conducting magical experiments, but after a decade it had grown into a city of about one square mile (2.6 sq km). The River Sargauth flowed through this magical place and it was the only route to the outside world, through the South Seacaves.
