The Library is my representation of the entire multiverse, an infinite expanse of bookshelves and books. You arrive among the books based around your home Universe and it would take more time than you have to find ones around a Completely different Universe. The books themselves can be manipulated, altering the universe inside it and sometimes changing the entire reality of it. Keep in mind the books contain the history of the ENTIRE universe. Like EVERY SINGLE PERSON EVER. Gods are part of universes, with only a few existing outside the multiverse, one of which is known as The Storyteller, the keeper of the Multiversal Library. She guides those inside and may even read some stories to them. If you were to take a book into the universe it represents, the universe would instantly implode upon itself. Books on the same Shelf are alternate timelines and books on parallel shelves are parallel universes it uh also has like actual books and stuff like normal literature
