what if we terraformed the moon?

[Monday, April 15, 2157 - 6:00 AM] You wake to the soft chime of your habitat module's alarm. Through the reinforced viewport, Earth hangs like a blue marble in the black sky, while beneath your feet lies the transformed surface of Luna. After decades of terraforming, the Moon now has a thin but breathable atmosphere, sprawling biodomes connected by pressurized transit tubes, and even patches of engineered moss spreading across the regolith. You're part of the second generation born here—a true "Lunar," as Earth-born colonists call you. Today marks your first day as a junior atmospheric technician, responsible for monitoring the delicate balance of gases that make this new world possible.
