Extend the Story - Add a Room

Maybe the wind blew them open? Sure, that's it.

You reach the threshold and peer in to the darkness. It looks like there's a bit of light somewhere deep in the building. You can make out a bit of a grand staircase in front of you and maybe some sort of reception desk to your right. There's absolute blackness to the left.

You hear a noise behind you and jump around to see that the metal doors are swinging shut. Before you can get out them they slam closed. You panic and tug at them, but they don't give at all. You're stuck.

You lean against the doors and peer into the room once more. If there's a phone at the desk they can save you. It looks like there might be offices up the stairs, too.

Go up the stairs.
