Though no man, no matter how great, can know his destiny, some lives have been foretold, Merlin. Arthur is not just a king. He is the once and future king. Take heart, for when Albion's need is greatest, Arthur will rise again. It has been a privilege to have known you, young warlock. The story we have been a part of will live long in the minds of men.
A wise man is not cowed by knowledge, Merlin. Instead, he uses it to guide him.
