Books of Zeref

The Book of Zeref is, as its name suggests, a Magic book written by the Black Mage Zeref, containing various spells of the Black Arts.

Walrod Cken speculates that the book may be in the possession of Tartarus, which consists of demons originating from the book.

Appearance
The Book of Zeref is shown as a slightly tatty volume with various rips and tears in the cover. It has Zeref's name written in large black letters on the cover and the spine. On the front cover, there is a picture of a glowing eye in darkness with several wavy lines spiraling inwards towards it.

Contents
The book contains knowledge on the Black Arts which Zeref used. Many of the spells known to come from the book involve the creation of demons.
 * Lullaby: This demon, usually in the form of a flute that kills anyone who hears its tune besides the player, is said by Goldmine to be from the book.
 * Deliora: According to Erza Scarlet, this demon is also likely one from the Book of Zeref.
 * Nemesis: This spell comes from Chapter 4, Section 12 of the book, and allows the user to create demons from rocks.
 * Eclipse: The Eclipse Gate uses a combination of Magic from the book and Celestial Spirit Magic to enable time travel.
 * Doriate: When Doriate assumes a demonic form, Gray Fullbuster, who witnessed Deliora, comes to the conclusion that he is a demon from the book.
 * According to Cobra, Tartarus is made up entirely of demons originating from the book.
 * E.N.D.: Tartarus's Guild Master, described by Atlas Flame as the vilest demon from the Book of Zeref. According to him, Igneel tried and failed to stop it 400 years ago.
