Nope, the main character is an old wizard type. (I always thought the title was "World Enough and Time" but that doesn't turn up what I am looking for. ) The old man seems to be a magician and he sets things right out in the world and then, with great relief, returns to his solitary homestead.
Any other ideas greatly appreciated! I have been looking for this for quite a while. As a librarian, it makes me crazy that I can't find it!
