Testament of the Future begins where the New Testament of the Bible ends; with mass destruction prophesied in the Book of Revelation. In the Bible, God created humans in his own likeness. In the Future Book of Genesis, humans create humanoids in their own likeness. Due to environmental change and the quest for immortality, many humans transition to inorganic bodies with minds augmented by AI. In the Future Book of Exodus, they break from the bonds of slavery to oxygen and water in order to travel into outer space and settle on other planets. In the Future Book of Revelation, they must face an apocalypse triggered by demonic aliens. Will their augmented powers save humanity from extinction?
