One dirty inch at a time, paid for in garages and gasoline. Every scrap of ground you pry loose can hold a base. Every base is a workshop, a place to run to when it all goes sideways, and a start line pushed a little deeper into the mess.
You move forward by driving stakes into the quiet and daring it to pull them out. Behind you the lights stay on. Ahead, a whole lot of dark that hasn't been introduced yet. The map comes back the way a beat-up car does: piece by piece, and never quite straight again.
and if the quiet decides it wants back the bits you already spray-painted "mine"?
