Milo returned from the Lands Beyond to find that his bedroom had not changed in any way he could measure.
The walls were the same color and the ceiling was the same height and his desk was in the same position.

The adventure was always available — it was waiting, as all real adventures wait, for someone willing to begin paying attention.
