Fortune cookie

Yesterday I challenged my partner to make a fortune cookie equivalent for my world. She knocked the ball out of the park I think, her idea is as follows: some sort of snobbish wizard decides that their work is too good for posterity and buries a number of books from their library. Perhaps they even shred the work before throwing it in the hole. By some strange magical accident a tree grows up from the Book hole and snippets of text are found in each of the nuts that grow upon it. Either this can be a bit of quirky flavor in the world or it can be used as a story hook. Perhaps years later, long after the wizard is gone people use the tree as a divination tool taking advice from the nuts. Maybe a whole religion grows up around it, a monastery is built around it and monks guard it's sacred nuts.
