Moon Monument: Echoes of the Dark Sea

The original "Dark Sea Mother Universe-Bubble Universe" world view subverts the traditional "Dark Forest" narrative. In 2042, humans discovered a dark creation monument on the back of the moon that had been silent for hundreds of millions of years. They learned that our universe was just a bubble in the dark sea, and that the creation race was a group of observers trapped in eternal loneliness. In order to cure their loneliness and save the dark sea that is about to be exhausted, humans spent a thousand years and crossed 46.5 Billion light-years to reach the boundary of the universe. There is no savior chosen by heaven, only ordinary people passing on the fire from generation to generation, and finally illuminating the eternal darkness with the glimmer of light of a hundred thousand ordinary souls.
