Hidefall is a hidden city of thieves located somewhere in the Ranger's Despair mountain range west of Alent in Libaterra in the Third Age. It acts as the seat of power for the Union Workers and where the thieves' Assembly of High Masters decides the actions of all the members of the Union. The city's location has been deliberately kept hidden for decades, and no outsiders were allowed to enter until 1017 AE when Raul Emmenson brought a group of non-Union people with him into the city. The thieves of the Union have gone to great lengths to keep their city hidden although it has cost them much over the years.
