Fadrex Storage Cavern

Fadrex Storage Cavern appears in Mistborn.

The Fadrex Storage Cavern, introduced in The Hero of Ages, serves as one of the hidden caches of the Lord Ruler's atium, a critical resource in the final struggle against Ruin. Its discovery and defense mark a turning point in the battle for the fate of Scadrial, as characters race to secure the metal before it can be claimed by the dark god. The cavern's role underscores the lingering influence of the Lord Ruler's long-term plans, even after his death.
