You begin in an empty office. Turn to your right, all the way around, pretty much, and then exit the open door. You're going to go to the left when you enter the hallway, into the open door just beside the one that you just exited, that will be door number 316 that you are entering, if you keep track of that kind of thing. There is a lonely pillar just over there once you enter the door. Go ahead towards that lonely pillar and have an engaging conversation with it, perhaps keep it company, because you are done. You're where you need to be.
