Okay, so in Harry Potter there's the unbreakable vow, which means that you can't break a vow or risk your magic and life or something like that, but what if you did crossies behind your back? Would that cancel it out or maybe even make the vow the opposite? I see a muggleborn attempting it, sharing with the rest of the muggleborns when it succeeds, then they quietly take over the Wizarding World by making tons of vows and never telling a soul how they did it.
