In the far off year of 2030 all planets are hospitable, so planetary empires are just everywhere that's normal.

Saturn is a Theocracy, because sometimes those happen

Saturn knights are cyborg psychic super soldiers, hand picked from the people actually stupid enough to think eye: divine cybermancy was an enjoyable game and are willing to make that their lives from now on

i figure if any setting is gonna have cyborg centaurs with raygun lances and psychic powers the far off year of 2030 might as well be it
