Stack A23

The year is X594. Somehow, even after demolishing its own existence due to dangerous intelligent A.I, humanity still lingers on Earth. After a long period of time, one injured A.I. remains on Stack A23. Stack A23 is different than the other stacks due to it's phenomenal height compared to the other stacks. Though first appearing at the lowest point in the Arctic areas, Stack A23 extends into the Mesosphere. Stack A23 is the only remaining place on earth to carry vegetation and water after the second ice age. An unknown organism is located at the peak of Stack A23. Scientists believe that this organism was the cause for creating the structure.
