Inside the cosmic inequilibrium, there are no constants. One system grows at the cost of another. But the grand interplay will eventually create something new out of both. The eons-lasting tug of war between a now-deserted planet and its companion is slowly coming to an end. The moon will fall apart and be consumed by its much larger neighbor. During this, rocks the size of mountainranges will descend upon the planet's surface, leaving nothing but destruction. In the end, nothing will be as it was before. A novel celestial object will be the ultimate aftermath of this encounter.
Been a while since the last time I blew a planet up. Kind of forgot how much fun it is
Ultra-basic idea behind it: have a civilization shape a planet to their needs (are they humongous termite-like creatures who just love to build termite hills? Who knows
), later desert it just in time before gravitational pulls rip its moon apart (at least on a cosmic timescale). Was quite some fun working on it. I hope you like it as well!
