"I believe in things I never used to. I think someone is trying to find me — has found me. And is calling. Who it is I don't know. What they want I don't know. But a little while ago I found out one more thing — this sword."
I picked the sword up from the table.
"It isn't what I want," I went on, "But sometimes, when my mind is — abstract, something from outside floats into it. Like the need for a sword. And not any sword — just one. I don't know what the sword looks like, but I'd know if I held it in my hand." I laughed a little. "And if I drew it a few inches from the sheath, I could put out that fire up there as if I'd blown on it like a candleflame. And if I drew the sword all the way out — the world would come to an end!"
