This post is to better explain the known powers of Dalian and Hugh, the Black Reading Princess and her Keykeeper. They, of course, have access to all the books in the Archives and they lend them to people and take them back, when the return date is approaching.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Book of Life


The Mystical Archives of Dantalian, contain an infinite amount of knowledge and books. Although, only the 900,666 phantom books inside the library are being referenced, the library contains the book of every living being that exists and that has ever existed.
Those books, contain the information about each and every different event that will happen on one's life and a person's lifespan is destined from the start of the book. Once everything in the book has happened, the person that the book is about, dies. It seems that, by connecting the last and first page of the book, the person can avoid death, but the life will have the same events repeating over and over.
Of course, destroying the book, or cutting the pages, results in the death of the person as well. This was revealed in an extra side story in the LN.
