If I were DM, congrats! You’re hidden backstory is that you were one of the most depraved rodeo clowns to ever have existed. You were patient zero of a necromantic crotch-rot epidemic plaguing your birth-nation to this very day. You traded your memories for the cure. No one recognizes you because you’re not wearing your signature make-up and are wearing more than just chaps and a crazed grin.
100% ok. Be prepared for weird stuff happening to you whenever I need a plot hook.
In other words, “My backstory is whatever you want it to be”.
If you were the DM and this bothered you, the player just gave you powerful ammunition.
You could even have it so whenever the player entered a shop in his home town, the shopkeepers looked at him with disgust and refused to serve him. The DM wouldn’t even have to necessarily come up with a reason. Just, that the player is extremely well known among the locals and they universally think he’s absolutely disgusting and want nothing to do with him.
If I wanted to do that part of the story for you, I wouldn’t have asked you to do it.
Sure, but given that the player did avoid doing the work, the DM can take the opportunity to punish them for it.
I don’t really like the idea of punishing players in game like that
We’re all there to have fun and we all have different ideas of fun
Acceptable but only if vague memories and impressions occasionally surface and lead to some plotline where you eventually rediscover yourself
Though that would work much better if you shared with the DM I suppose
Gonna be honest, I usually make my backstory like 2 or 3 sessions in, that way I get a feel for the character and can do something that makes sense. I usually start off with a rough idea, but I like incorporating themes from the story into my background
