Freedom
Freedom, Agnon reflected, was a funny thing. He had thought when he left Tartarus with Cronus that he was regaining his freedom. It was only later that he realized the truth: he had simply exchanged one prison for another.
He wished there was some way to gain real freedom, but he couldn't see one. If he left, Cronus might come after him or he'd probably run into the heroes, either way he'd most likely end up back in Tartarus. He wondered though if it might not be worth it just to feel free, even if only for a little while.
