Birthplace of the demons - The Great Rift
The Great Rift appears because of the abuse of machines. Lakis dropped from the sky and held up the ax to chop the human beings without any warning. The earth were torn apart, and the civilization collapsed in a moment. Countless human beings had been destructed before they realized the disaster. The Great Rift becomes the pronoun of this place.
Shoggoth rules the Great Rift, it is waken up by the demons to slaughter human.
