Backup Book (under edit)

Intro

"Hey Natsu, did Igneel ever say anything about a second book?"
Erza asked him. They were currently standing on the rubble of Tartaros. Erza held up a book that was different from END or any of the other books. Natsu shrugged but walked over to look at it.
"Maybe we should let master see it..."
Lucy trailed off unsure what to do. Erza nodded and secured the book in her arms. 'No place safer' was what everyone was thinking. Once they all got to the master he began inspecting it with Mavis, neither of them had seen a book like this before.
