Your name is Bob Smith. You are an average Bob Smith with hair and everything.
Life on the Mars settlement has taken it's toll on you, and you've decided to take a walk. For some reason you've gone really far away from civilization and it looks like complete **** from here. From your vantage point you can see the main city block and the giant shield tower projecting the bubble that allows life to exist on Mars.
You'd feel sorry for someone if they were to knock out the shield. You can't imagine what would happen to them.
