The Walls were a crescent-shaped mountain range that towered up to 20,000 feet (6,100 meters) over Halruaa, surrounding the country on three sides.


Prior to the Spellplague the mountains formed a natural defense for the realm. The three sections of the mountain range–the Nathaghal, Lhairghal, and Muaraghal Mountains–formed a stout border.[2]

Unfortunately, the range's height made it difficult for Halruaans to escape the effects of the Spellplague. Three passes connected the remnants of Halruaa to the rest of Faerûn.[1] The Azhal Pass and Talath Pass were difficult for a large group to travel. Only the wider High Aluar pass offered a secure route for any sizable group.[2]
