" Ged said at last, speaking low, "There is a thing that I fear, Estarriol. I fear it more if you are with me when I go. There in the Hands in the dead end of the inlet I turned
upon the shadow, it was within my hands' reach, and I seized it - I tried to seize it. And there was nothing I could hold. I could not defeat it. It fled, I followed. But that may happen again, and yet again. I have no power over the thing. There may be neither death nor triumph to end this quest; nothing to sing of; no end. It may be I must spend my life running from sea to sea and land to land on an endless vain venture, a shadow-quest. "
