“He means that I must drive you off, or he will close the vent through which my sunlight falls. I drive away those who pay to see me by foretelling their futures, and I will foretell yours. You are young now, and strong. But before this world has wound itself ten times more about the sun you shall be less strong, and you shall never regain the strength that is yours now.

The tremor ceased, and he sat again, older-looking and paler than before. “You are only a fraud then,” I told him as I turned away. “And I was a simpleton to believe in you even by so little.”

Then I saw the knowledge growing in him, so that he seemed to unfold in his great joy, as though he were already basking in the brighter light of his own day.
