Built into what looks like a former sewer, the narrow hallway has curved metal walls and is dimly lit by torches mounted in makeshift stands on either side. Dry wooden planks cover the floor and provide a sturdy footing, secured firmly in place by large metal bolts. The air is extremely cold in the area, leaving bits of frost on the slightly rusted walls.
