Orochimaru starring in a Western? 
 Sephiroth weapon switching? 
 A Gunslinger Randall Flag? 
 The lore is a strong intermix of Book of Revelation's Seven Horsemen of the Apocalypse and American Civil War(the actual one, not Marvel arc). The unrest comes to halt when a Comet strikes Kansas(nothing Kryptonian), causing the 'seven' warring factions(like the seven biblical seals) into an Armistice. Meanwhile there is a secret message in terms of three separate prophecies, for which the Four Horsemen(Death, War, Famine and Conquest) are on a quest. When things can't go presumably anymore weirder, Death falls in love with Chairman Mao II's daughter(yup, Chinese in exile are a faction among the seven, east of west, see) and is sidetracked from Horsemen mission of apocalypse. And this much is only half of the premise. Anyway Clint Eastwoood-y Nemesis dressed Death in a Priest like universe is kind of strangely alluring. 
 Though everything in this sci fi alternative history take is bat-shit crazy, I am intrigued to follow the series further.
