The first planetary body to host permanent human habitation, Earth’s sole moon competes with Titan for the second largest population on a planetary body in the solar system and remains a lynchpin of culture and economic activity. Lunar history has been shaped dramatically by the Fall. Before the need to evacuate Earth arose, it was expected that Luna would remain largely an automated mining concern, never attaining a population of more than a few million. Luna was never seen as an economically viable location for colonization, the focus instead falling on Mars and the outer system.
When the Fall came, every polity that couldn’t hope for a shot at Mars or elsewhere set its sights on Luna. The Indians were the only great power that had invested heavily in Luna. The other three major settlements, Erato, Nectar, and Shackle, were multinational and hypercorp concerns with no strong national affiliations. These three cities swelled overnight into polyglot refugee camps, while the Indian settlement, New Mumbai, was nuked black by the corps when it became apparent that a TITAN infection had taken hold there.
Bereft of nationhood, Lunars developed their own resourceful, tough-minded culture that emerged as a counterbalance to the radicalism of the outer system and the excesses of Mars.
Transportation on Luna is largely by suborbital rocket, although trans-sonic bullet trains also operate along shorter routes. The major space port is at Nectar. There is also a skyhook—a massive orbiting satellite spaceport that drags a massive tether, which acts as a space elevator along a track running across the Lunar surface south of the equator. As a result, many smaller cities lie along the skyhook track.
