The High Forest is a large, old forest located in northwest Faerûn. It is bordered by the Nether Mountains to the north, the High Moor to the south, the Evermoors to the northwest, and the Anauroch Desert to the east. The forest is mostly unexplored, but is still inhabited by numerous humanoids - especially wood and wild elves. At the centre of the forest lies the Star Mounts, which provide the headwaters of the Unicorn Run and Heartblood river. Locations of note inside the High Forest include the Grandfather Tree, Hellgate Dell, Karse, and Shadowtop Cathedral.
