Urteau Cavern beneath Canton of Inquisition

Urteau Cavern beneath Canton of Inquisition appears in Mistborn.

The Urteau Cavern beneath the Canton of Inquisition emerges in 'The Hero of Ages' as a pivotal hidden cache site, one of the nine storage facilities prepared by Preservation to safeguard humanity against the prophesied end of the world. Discovered by the city's underground resistance amid the chaos of the Citizen's regime, it holds vital supplies, weapons, and crucially, the missing atium beads essential for Vin's confrontation with Ruin. Its unearthing marks a turning point, providing the resources needed to avert catastrophe, though its late reveal underscores the intricate web of Preservation's contingency plans across the Mistborn saga.
