The Watchwall was a massive, magically engineered length of stone wall, stretching from the fortress city of Glarondar to the slopes of Umbergoth, thus extending the defensive barrier of the Dragonjaw Mountains another fifteen miles, up to a rock-like fortification containing one-third of Aglarond's armed forces.[1] It was constructed by the galeb duhr living in Tannath and Undergoth in 1085 DR.[2]
