Dusk: Volume 1

But what if someone found a book that contained within true scientific foreknowledge? Something that was not just evolutionary with regard to our knowledge of history and archaeology, but revolutionary? Something that presented evidence -- hard evidence -- that someone, somewhere, knew how the future was going to happen before it happened?

What if that book foretold the dusk of humanity, the end of our light?

A 3,000 word short story.
