Not so much a novella as a maintenance manual. Where did Merlin go all these years? The greatest of wizards fell for one of his own tricks. Now he's trapped inside the complex, a boundless expanse of interiors. All of which need sweeping on a regular basis.
Imprisoned in a spectral tower by Nimue, Lady of the Lake, he's had all this time to reflect on his condition and find a way out. So far he hasn't managed it.
This short but lovingly-formed book details the great sorceror's reflections on his life and his search for meaning within a series of countless mezzanines, waiting rooms and storage spaces. Also, there some pictures of random machinery.
