You're not going to wait here in comfort while outsiders steal your dream. You take apart your camp, keeping a few components that could be used as weapons. The rest of it you pitch into the sewage flow.
You make a rough map in your head of the sewer and plot your best route from one end to the other. On your first few trips not much of note occurs, although you do manage to improve your map and discover several neighborhoods that you never knew about.
You are a nomad now. You make dozens of trips through the great winding maze. The trek is your lover. For days you navigate by stench alone, eyes closed, chest swelling with elation.
