The undercity beneath Megropolis One on Pluto became inhabited by outlaws who had escaped from the Company's society above ground. There was no lighting in the undercity save for candles, nor were conditions favourable; much of the surface was covered in filth. Mandrel was the leader of the outlaws living in the undercity. They were forced into the city whenever they wanted food as they had no local sources. Many of those aboveground had heard of the undercity and those that lived there, but knew few details.
