"Not an apocalypse. There had always been plenty of those - small apocalypses, not the full shilling at all, fake apocalypses: apocryphal apocalypses.

And those little worlds had ended. But there had always been somewhere else. There had been the horizon, to start with. The fleeing refugees would find that the world was bigger than they'd thought. A few villages in a clearing? Hah, how could they have been so stupid! Now they knew it was a whole island! Of course, there was that horizon again..."
