I think that the story is a clue as to whats ahead. Maybe that each of you will suffer similar fates? Maybe just the places you will go? Maybe what your weaknesses are? I don't know, but it cant be a coincidence. And as for Zelda... I don't think they really work the same way as the Hero and Ganon. They live their lives from birth to death being Nayru's Emissary. Born ready to serve should the need arise. That's because their blood carries that old magic within it. The Hero so far as I know has only ever been descended of a previous hero once. And that was your grandson Shade. For all we know the Hero may still yet come, or maybe you're what we get. And maybe Ganon will come... I wish I had answers. But really we can only pray for the best and prepare for the worst...
