"Not a wound in the earth," the man said behind me, "but a wound in space itself."
I snorted. "And you convicted me of a heavy-handed metaphor," I said, turning back to face him.
"But my metaphor is apt," the man said, now appearing as a mere shadow against the starlit sky. "What you witnessed is the light of a foreign sun, a red sun, shining through a sort of rift between universes. And it was shining on red dust that also came through the rift."
"Well, that was my other guess," I answered flatly. "Diffraction or an alternate universe."
"But I'm quite serious," the man said. "Further, the rift is why I am here tonight; I bear the responsibility of ensuring that the post-solar glow remains a secret."
"So now that I've seen it, I suppose you have to kill me?"
"You are way ahead of me," the man said.
