No one asked for this one, but…
If you made lore for a character you’ve had since you were 16, and you’re in your 20s now and have a better grasp of narrative structure and power creep, you can just retcon the dumb stuff. Like you can do that for free. You’re not beholden to the junk you wrote 5 years ago, and you don’t need to justify removing it if it sucks.
unasked for addendum:
You can also retcon out gross people you no longer want to associate with. Replace their characters with NPCs or just cut them entirely.
