You are in a corridor made of concrete. There are numerous metal pipes and ventilation shafts running above your head. To your North is a locked door. To your South, the corridor continues for about 20m before turning a corner. To your East, the ceiling has collapsed and the corridor is blocked by rubble.
You can hear an intermittent dull rumbling noise coming from above and a low hum coming from behind the door to the North.
You open the briefcase full of files. There are roughly a hundred of them. They are all uniform in shape and appear brand new. You are unsure why you have them or what possible purpose they could serve; your fingernails may be getting a little long, but there's no reason why you would need 100 nail files just for yourself.
