Ride inside a small minecart in first person, with bare hands extending from dark green sleeves to grip its worn metal front rim. Rails curve through a rocky cavern beneath timber supports and warm hanging lanterns. Nearby posts and jagged rocks slide past as the cart rounds the bend, then rolls onto a narrow bridge with rope side rails above a dark drop. Ahead, a stone-lined tunnel frames a bright daylight opening. The viewpoint travels with the cart into this warmer passage, keeping the hands, cart rim and track visible as the exit grows larger.
