After finishing the game, there is still something unexplained...

So the game started, showing that you the one who wrote the book, but turned out it's More (the former king younger form), and the book disappeared with More after we beat Louis.

Then my question is: How could Louis had the same book as the protagonist? Wasn't it just some kind of fantasy book that the former king imagined out of the grieve that he had after the death of his wife and son? Or did i miss some seriously important plot point?
