Book of Demise

The Book of Demise (終焉の書) is the oldest known divine document.

About
The book was written more than 12,000 years ago and describes every possible way to end the world. Despite that it is from a time when human civilization didn’t exist, it was delivered along with a supplementary reading dating from the same time that translated the contents of the book into modern English, Spanish and Chinese.

The book was “sent” to the human world two and a half years ago, and after the events with the Eternal Compression Clock around a year ago, the danger and truth of the contents of the Book became evident and well-known in the human world.
