The High Moor is a large, monster-infested, open moorland in western Faerûn, and the High Moor is bordered on the east by the Serpent Hills and on the west by the Misty Forest. It was created in about -10,500 DR when the fallen kingdom of Miyeritar was destroyed by the Vyshaantar Empire's magics during the Crown Wars.
The High Moor contains numerous ancient ruins and structures, but the most familiar include Dragonspear Castle on the western edge, Hammer Hall, a dwarven keep near the banks of the northern Highstar Lake, and Orogoth, a large ancestral hall near the Serpent Hills. Forays into the High Moor are usually based in the town of Secomber, north of the region.
