*You discover a damaged sheet of paper on the rusty concrete floor* Don't fall off the edge. Everything will be alright. It's very difficult to navigate here. Try to remember where you came from and where you want to go. You can trust the radios. They kept me safe. Listen to their warnings. If you brought a watch or compass, do not look at it. There is nobody else here, don't believe your eyes. Please don't fall off the edge. Keep moving, don't stay in one place for too long. The radios think. Don't fall off the edge. The radios think. Don't fall off the edge. *The writing is no longer legible.*
