Both moons are inhabited by dead people. Not just the souls of dead people: their entire bodily forms are thought to be reconstituted on one moon or the other. Which moon you go to after death is determined in a complex way by a number of factors including your horoscope, your genealogy, your chosen profession, the number of children you have, and the length of your hair. There are Moon Tellers whose entire occupation is forecasting which moon someone will end up on. They have subtly different methods; there are several Moon Telling schools and sometimes bitter rivalries between them. You can make a fortune as a Moon Teller because everyone is desperate to know where they’ll end up when they expire, although as far as anyone knows neither moon is preferable to the other. The only difference anyone has noted between them is that one appears to be tinged red and the other blue. When someone suggests sending a rocket to the moons to find out what other difference there might be, if any, he is assassinated shortly thereafter.
