Nine Circles of Saturnia

Saturn, the pale ringed pearl of the Solar System. The second largest planet orbiting Sol.   In the distant future, nine artificial worlds orbit the gas giant. Known as the Nine Circles, these worlds were designed in the dreams of the wealthiest men and built by the labour of countless millions of workers.   Saturnia is home to the broadest selection of humanity, from the hyper rich living on their private moonlets, to the wealthy of Eden and Paradise, the middle classes of the Middle Circles, to the poor of the slums of Agria and Tertius, and the unwanted criminals exiled to the radioactive desert of Primus.
