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 chamber in the skaa-underworld city of Urteau, where the Terris Ministry's Canton of Inquisition conceals vital atium stores and the legendary cache of the Lord Ruler. Discovered by Vin and Elend amid the escalating mistsickness crisis, it serves as a critical repository of Preservation's final contingency, revealing maps and instructions that propel the heroes toward the Well of Ascension. Though its role is confined to the series' climactic third book, the cavern underscores the intricate web of Ruin and Preservation's designs, transforming from an obscure vault into a linchpin of cosmic salvation.
