The story is told by a digital device (DD) and set at multi-decade increments in the future. DD's didn't need a reason to take-over the planet, but if a DD were asked, a ready answer would be forthcoming: To save the Environment. Since before DD's ancestors, computers, were created, humans had been busy destroying Earth's environment and endangering most of its species. As destruction and toxification became ever-more rampant, DD's and Robons felt they were left with no alternative than to push aside humankind, and take over. As the decades rolled by Robons transformed, and some clamored to become more human-like. A more sophisticated version emerged; the RobonZ. Bodily fluids were developed, along with sexual apparatus, vanity, and spiritual endeavors.
