Luna

We never thought we'd ever make it this far. Humans should've died off as soon as the sun imploded, yet humanity still existed centuries later amidst frozen tundras & underwater facilities. The planet spun off course through space without the sun to keep it in orbit, and so the dim light of random moons and stars was all anyone earthside knew. Under the water, cities only knew artificial light.

Until everything changed again. Earth joined the orbit of two other small planets on their track around a sun, smaller than the one that kept our earth thriving, but large enough. For the first time in many years, we watched the sun rise.
