Test Book

The Test Book is one of the many Books of Zeref. The book contains spells that summon demons known as Cardascian Phantoms. The book is said to be one of the very first books that Zeref wrote and served as a rough draft for the books which he would write later in his life that contained more powerful demons such as Deliora. The book was allegedly discarded by Zeref on the island of Cardascia, which is where he was said to have written it. The destruction of this book was requested by the magic council to what was known as the Test Book Team which comprised of indiviuals from different guilds that were handpicked by the Magic Council. The initial reason that this book was requested to be destroyed was because the Cardascian Phantoms had driven the original inhabitants of Cardascia from their homes and off the island.

Appearance
Though the appearance of Books of Zeref remains a mystery ,the Test Book is apparently a thick, brown leather-bound book that has no patterns on it whatsoever.

Contents
The book contains knowledge of Black Arts Zeref used. However, unlike the rest of the books, this book ocntians knowledge that is not nearly as advanced as depicted in other Books of Zeref, implying that this book had to have been written when Zeref was younger.
