The best part would be that if they went to another wizard to have them break the curse they’d tell them that there was no curse. More paranoia fuel.

Like the universe antagonizing them in the form of petty enemies who talk shit… who get all up in my goddamn shit.

Honestly I’m pretty sure you can already do this. Your average person is remarkably superstitious and believes in angels and demons and such, it doesn’t take much to also think they were cursed. Lol
