Thief of Time - Timelesness

Death looked down at the world. Timelessness had reached the Rim now, and was expanding into the universe at the speed of light. The Discworld was a sculpture in crystal.

Not an apocalypse. There had always been plenty of those - small apocalypses, not the full shilling at all, fake apocalypses: apocryphal apocalypses. Most of them had been back in the old days, when the world
as in 'end of the world' was often objectively no wider than a few villages and a clearing in the forest.

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...
