Books

**Books** are items obtained in the Library by defeating Guests during a Reception. Books are needed to register Invitations to the Guests who will end up coming to the Library. Defeated Guests will turn into Books and they will be added to the collection of the Library. Books used in an Invitation are lost if the player loses the Reception against the Guests.

## Gameplay

###  Burn Books

Each Book contains a specific pool of Combat Pages and Key Pages with a limited number of copies. Books can be **Burned** using the "Burn Books" tab accessible from the main screen of the Library to drop these pages for use by Librarians in combat. Key Pages are equipment for the Librarians and Combat Pages are used as actions during Receptions.

Burning a Book will make it drop 8 random Combat and Key Pages from its pool, depleting that item until all the items from that Book are collected, which will then reset the rewards back to the maximum of its pool. The only exception is the  **Book of the Red Mist**, which drops only 4 items when burned. The player can also manually reset the rewards when burning a Book. The rarer the Page, the lower the chances of obtaining it, unless there are no other drops. However, note that after obtaining the maximum copies of a Key Page, they will no longer be obtainable from any Book that has them in their item pool.

### Special Books

Some Patron Librarians will require specific Books to grow their Floor. On some occasions, Angela will write Books of her own knowledge on particular topics, which will be needed to advance the story. Books obtained in this manner cannot be burned. The Books given by Angela are:

* **Book of Something** (Will always be available)
* **Book of the Distortion** (Obtained by completing  Zwei Association II. If lost, can be re-obtained afterwards by successfully completing any Episode)
* **Book of Lobotomy Corporation** (Obtained by completing  Zwei Association I. If lost, can be re-obtained afterwards by successfully completing any Episode)

## Story

### Background

Books are made from the Library's Light. An infinite number of Books are found within the Library, though the contents of most Books created as part of the Library are meaningless gibberish. A Guest who is defeated while within the Library becomes a Book that contain the Guest's memories and experiences. According to the Patron Librarian Tiphereth, books are consumed once a being fully understands its contents. Books, however, may change from reading to reading, forcing one to read one book multiple times in order to fully understand it.

The Library director Angela intends to collect the "One True Book", a special Book that holds information capable of making her human—freeing herself from Lobotomy Corporation's facility X-394—and freeing the facility's former Sephirot.

Upon Lobotomy Corporation's collapse and transformation into the Library, the Wing's former employees, as well its contained Abnormalities, were also turned into Books. These employees and Abnormalities were effectively placed into stasis to await reawakening by Angela. The employees became Librarians. The Abnormalities were notably given Books with environments specially designed for them.
