Earth, Trading City.
As night falls, this super city sprawling across the artificial island chain in the Pacific Ocean lights up.
Viewed from above, the entire city resembles a giant net woven with light.
The different colors of light within the city outline the seven districts.
The white light of the Human Clan district, the blue-green glow of the Sea-dwelling Clan district, the red light of the Re-adaptation Clan district... each light represents a race within the Earth Alliance.
And this city was jointly established by seven races.
The Descent War of those years plunged Earth into successive periods of climate disasters, energy crises, and waves of automated unemployment.
Especially the emergence of automated unemployment waves caused many races to fall into turmoil.
The advanced technology of the Moon Eclipse Clan replaced manual labor, making it difficult for ordinary human power to create value.
