So, I'd just like to start by saying this is a random assortment of notes I took while playing the game, a majority of which either translated off of a Japanese site or scrambled together from multiple forums such as reddit and GameFAQs. As such, I have found errors while completing this list and am unsure if there are yet more here. This is also my first time making a guide, so I apologize in advance if anything is excessively difficult to read or poorly organized. I'll do my best to update as people in comments provide information or criticism of my formatting. Without further ado, here it is.

This list is for authoring books that can be published for mountains of fol at Acendros' item shop; you would turn it in as a quest item. In order to author a book it needs to be created by the character associated. Meaning you will always get the same three books from Raymond, and will never get one of Laeticia's books from Raymond. The reason some of these have materials next to them and others don't is that I noticed the wiki I got this list from was often wrong, so I don't trust the material listings at all. Any books with listed materials are ones I personally found.The "3*" or "4*" etc next to the books are their rarity, which determines how much you get in royalties.
