The Pachacuti is the prophecy predicting the end of the world. Manco Capac, a powerful djinn, fortold this powerful destruction to his Incan followers. In an emergency, he would come back and wipe out their enemies. It was kept secret, told only to his most loyal of Incan priests, in case it was used against one another during an the Incan wars for power. Unknowingly, Virgil McCreeby tried to unleash this destruction in The Eye of the Forest because he thought it would bring him riches and ultimate power. Mistakenly, Dybbuk Sachertorte believed it would restore his powers back, but did nothing except unleash his evil half.
Pachacuti is named after the ninth Sapa Inca of the Kingdom of Cusco where he ruled the Inca Empire. Most archaeologists now believe that the famous Inca site of Machu Picchu was built as an estate for Pachacuti.
