The High Moor is a large, monster-infested, open moorland in western Faerûn, and is bordered on the east by the Serpent Hills and on the west by the Misty Forest. It was created in about -10500 DR when the fallen kingdom of Miyeritar was destroyed by the Vyshaantar Empire's magics during the Crown Wars. Rhymanthiin, the Hidden City of Hope, created by a large group of notable magic-users led by Khelben "Blackstaff" Arunsun, Tsarra Chaadren, and Ualair, is located on the High Moor.
