What would be a good psyop to maintain control? It would be useful to have an attractive narrative every couple centuries while society drastically changes (probably often intentionally)
If they don't have science: give them gods. If they become "renaissance" , give them saints. If they become political , give them "parties" and "nations". If they become technological , give them "races"
The truth is probably often way less uniform, therefore less simple to distinguish. It looks less like "flavors" and more like factions whose splinters are based on pure fault lines of their exigencies.
You wouldn't have the "blues , reds , greens , yellows" nicely packaged into palatable grades. Instead you have "the ugens that were a bit too bugens." You might "good guys that became that became bad guys that became good guys" . You might have "they're helpful but don't get close, they're also mean." Or "they're noce but they screw up a lot so don't rely on them".
Anyone giving you a nice crisp pantheon package is probably ... the bad guys.
