Main Tunnel and Warehouse Cavern

Main Tunnel and Warehouse Cavern appears in Mistborn.

The Main Tunnel and Warehouse Cavern first appears in The Lost Metal as a critical subterranean network beneath Elendel, serving as both a clandestine meeting place and a strategic hideout for the Ghostbloods. Its vast, dimly lit chambers and twisting passages allow for covert operations while shielding sensitive activities from the prying eyes of the city above. Over the course of the novel, the cavern transforms from a mere logistical hub into the epicenter of a high-stakes confrontation that determines the fate of the city and its leadership.
