East of the Buried Realms lies the small domain known as the Deep Wastes, this runs beneath the Dalelands and the Moonsea. Sparsely populated and largely wild, the Deep Wastes are home to the now-ruined drow city of Maerimydra, which once held Shadowdale as a conquered surface land, the Deep Wastes extent as far as the Earthspur Mountains beneath The Vast. Few easy access points exist, however, so large portions of the domain are poorly explored.
