This sets up the most annoying paradox as well. Something of Star Trek Quality -- if the Rule of Rules (ROR) states that every rule has an exception, and the ROR *is* a rule, then... wait for it... doesn't the ROR have an exception as well?
You might be saying now "I want some cheese". But you're also saying "but the ROR is a Rule, and therefor cannot be circumnavigated". So, what you're saying is that the ROR effects all other rules, but canont be affected itself?
Well, I'm sorry. That don't happen.
