"There isn't one. It's magic. I can offer all that stuff on the cheap. I want people to have a nice place to live and not die or worry about paying the landlord. I get to call myself Empress and lay down magical laws-nigh-unto-physics around Mars so people don't stab each other or set anything on fire, and they get to live in a place where those things don't happen and they get the necessities without a hassle."
