In Lak'ech

The In-Laqetti was a supposedly mystical tome of prophecies dictated by Tatsuya Sudou to Akinari Kashihara. In reality, its contents were completely false until Sumaru City's powers brought them to reality when the members of the Masquerade forced the completion of the Oracle of Maiya.

History
Tatsuya Sudou had always been troubled by mysterious voices resounding on his head, threatening to drive him insane. His teacher, Akinari Kashihara, believed the voices belonged to aliens wishing to spread a message, and wrote them down in the single volume that was In-Laqetti. In reality, the voices were all Nyarlathotep, orchestrating the downfall of Humanity.

The major prophecies contained within the volume were the Oracle of Maiya poem, and a text which told of the new advent of the Last Battalion - a mythical final group of Nazi sympathizers returning for another bid for control of the world. Specifically, the book "revealed" the Nazis had been hiding in Antarctica, rebuilding their ranks and growing in power until they were ready to make their bid for global domination.

While nothing more than a simple rumor, release of the book after the Masquerade had successfully forced the Oracle of Maiya's poem prophecy's completion allowed Nyarlathotep to use Sumaru's powers to bring the Last Battalion to reality from nothing in a bid for the power of Xibalba.

Following the destruction of the Innocent Sin timeline, the book was never written. However, it was found, strewn with other memorabilia of both Innocent Sin and Eternal Punishment in Philemon's Extra Dungeon. It was one of the items required to trigger the fight against Tatsuya Sudou.
