[@Whoami] I did mention 'all-OC plots' would need to be pretty snazzy and for what you proposed, it seems like the world would be more of a secondary thing to the issue of keeping secrets and identities, which kind of lacks the fun I think LoK has to offer. The issue between benders and nonbenders is an interesting one but I don't think it would hold my attention compared to say, tweaking with canon events and characters.

Since time is rare for me, I'd rather go forward feeling confident and with all-OCs, it's not quite there.

[@Saltia] One thread would likely be more clean, so that's fine with me.

I figure the thing about having it set in the muggle world would be like, the wizarding world has become too dangerous if say, the war at Hogwarts resulted in some kind of loss with people fleeing more than fighting. My thought would be to have whichever pair blend in with muggle life while trying to defend other muggles from stray magical dangers like beasts or the Dark Lord's followers.
