A world where the dead are transformed into books. When a person dies, the body is divested of the soul, and when the soul departs from its body, it is crystallized into a book. Written in that book are all the memories of that souls life. For anyone who touches that book, the dead persons past can be relived. It is in the Library of Bantorra, created by Bantorra, the God of the Past, that all excavated books are stored. It is run by an elite organization known as the Armed Librarians. Under the direction of Acting Chief Librarian Hamutz Meseta, all Armed Librarians possess an extraordinary combination of encyclopedic knowledge and fighting skill. For this reason, it is said, the Armed Librarians are the most difficult profession to enter in the world.
