In the end, the Lunar Union would inevitably reach out to the one remaining nominally communist power for its uranium needs. China would ship the fissile materials, and in exchange, the Union would connect their power grids.
Additionally, China was given equal stake in all decisions regarding the reactor, as well as the ability to keep their own people there for inspections.
With the deal completed the lunar colonies were able to avoid blackout and continue their good lifestyle, with electricity use ballooning across the nations. Home computers connected to the internet became common in every home and electrified trains became the most common form of transport.
It also signaled an end to political independence. The very nature of being such a small nation in the shadow of a giant, albeit far away, lead them to end up following China's lead on most matters.
The space race became known as a "new cold war" to those on Earth, with the west half of the moon under China's influence and the east half being American. Both giants would continue heavily funding their programs, sending tens of thousands to claim the celestial body. China viewed it as a potential solution to their overpopulation problem, though the expense of shuttles proved it to hardly make a dent in their total population.
Russia would eventually restart their space program. Attempts at reconciliation with the LSSR failed, so they made a new colony in the Great Island of the Seas.
Japan, too, made a small moon base of their own, and several other European countries joined the space race by joining the EU's Verne project. These would be, as a rule, small vanity projects with little hope of a profit within a few decades.
The New America colony would eventually be reformed by President Bill Clinton, with the colony officially subject to US federal labor laws. Still, it would remain dominated by corporations and have a frightfully low standard of living compared to Horizon.
Horizon became the golden child of space colonies, known as "sci-fi city" back on Earth. With the most advanced technology built into its foundations and billions of dollars of investing, it would become the favorite destination of billionaires's lunar homes.
The Kingdom of Luna stayed a backwards theocracy, simply the largest among dozens of poor independent settler states across the vast emptiness of the moon. They largely portrayed themselves as a constitutional monarchy like the United Kingdom to Earth, playing on reactionary romantic notions for tourists from the western nation's colonies.
In the coming decades, the Socialist Republic of the Moon would prosper. It maintained and grew its industry, staying the only nation on the moon to natively produce oil, rubber, and other advanced industrial materials for years.
President Josephine Steele would step down after serving for 16 years to work directly with the film industry and let others take leadership of the nation.
They would continue to advertise to disadvantaged minorities back on Earth and would serve as a beacon of hope of socialists around the globe, staying stable even as mainstream liberalism declared that it would either stagnate or liberalize as it grew.
AN: So that's it, for now. I'll post more epilogue pieces if inspiration strikes. Feel free to make requests or ask questions. Maybe I'll make a sequel quest (probably on the same thread) after I'm done with my next quest (which I just started), set years later when you actually have enough people to be a nation and actually do stuff.
