I scanned for more warning stripes or marker paint that might indicate exits but I wasn’t picking up anything. Still no sign of any human prisoners, that was good. I made it all the way to the top, to where a temporary scaffold/platform had been installed to one side of the shaft, near the assembler’s interface housing. The light source was there, a self-contained safety globe attached to what was left of the hand rail. Parts of the platform had fallen off, but I was able to crawl along one of the assembler’s crane arms and then climb down to it.
