[Tau Zero]

Here's the great final sentence by Lovecraft's Dreamquest of Unknown Kadath:

And vast infinities away, past the Gate of Deeper Slumber and the enchanted wood and the garden lands and the Cerenarian Sea and the twilight reaches of Inquanok, the crawling chaos Nyarlathotep strode brooding into the onyx castle atop unknown Kadath in the cold waste, and taunted insolently the mild gods of earth whom he had snatched abruptly from their scented revels in the marvellous sunset city.

Now THAT is what i call an ending!
