The Atlantean Tomes is the name given to a book penned by the Celestial Crab with two purposes. One was to serve as a Shadow Artifact to hide the powers of Shadow Magic inside of before his death, and the other was to create a complete record of universal events. Due to its status as a Shadow Artifact, it has magical properties. Every time a new event happens in the universe, no matter how mundane, a page is created to document it. If something is not documented in the Atlantean Tomes, it does not exist and never has existed. If a page is torn out of the Atlantean Tomes, the book simply makes a replacement. Even though it primarily functions as such, it is not just a history book. It contains everything from in-depth tutorials on how to do everything possible in the universe (spanning everything from cookie recipes to martial arts training), documents defining and explaining in great detail every person, place, and thing in the universe, and every prophecy ever written. In order to fit all this information, the book uses a Shadow spell that makes it much larger on the inside than the outside. Oddly enough, the book, when first opened, the first page is blank. However, if one writes a question they have on one of this blank sheet, the book automatically flips to a page that answers their question (this is how the book works). As it is a Shadow Artifact, this book is one of the only ways to learn Shadow Magic without tainting one's soul. The book is kept in the final level of the Trial of the Sharks on Atlantea, so only those who can pass all of the many challenges of the Trial of the Sharks can access it.
