If a conworlding project persists long enough, I’m sure we’ve all second-guessed some aspect of our worlds.

I’ve learned to incorporate my own second thoughts into the universe itself. Don’t like how I translated something into English? OK, it was a mistranslation that has now become too ingrained to change. Not sure how to portray a particular religious sect? Now there are two different denominations of that sect. Uncomfortable with how I characterized a controversial historical figure? OK, now there’s a historical revisionist movement that seeks to paint him in a different light. Have some idea I like that really doesn’t fit the lore? Now it’s an in-universe urban legend/TV show.
