Balancing Hindsight or Foresight

Expect the following story type - A "What if", AU/AR and Char. Ooc, still magical world - Sent to prison upon the death of the Dark Lord, the Hero is bound by the ancient edifice on an island in the middle of nowhere. Laws that came into effect days before the final battle bound his battle actions and the rest of his life there... that is until the day he died.
