The Librarian watched them from the open door, while giving himself a philosophic scratch. Then he turned and shut out the night.
It was warm in the Library. It was always warm in the Library, because the scatter of magic that produced the glow also gently cooked the air.
The Librarian looked at his charges approvingly, made his last rounds of the slumbering shelves, and then dragged his blanket underneath his desk, ate a goodnight banana, and fell asleep.
Silence gradually reclaimed the Library. Silence drifted around the remains of a hat, heavily battered and frayed and charred around the edges, that had been placed with some ceremony in a niche in the wall. No matter how far a wizard goes, he will always come back for his hat.
Silence filled the University in the same way that air fills a hole. Night spread across the Disk like plum jam, or possibly blackberry preserve.
But there would be a morning. There would always be another morning.
THE END
