Most modern fantasy just rearranges the furniture in Tolkien's attic.
Rincewind tried to force the memory out of his mind, but it was rather enjoying itself there, terrorizing the other occupants and kicking over the furniture.
It was also a room full of books and made of books. There was no actual furniture; this is to say, the desk and chairs were shaped out of books. It looked as though many of them were frequently referred to, because they lay open with other books used as bookmarks.
