Negotiations between Earth and Arcadia [Unlimited]
About
[Worldview] In the distant future, rapid climate change and ecological collapse rendered Earth a planet where humanity could no longer survive. As a final hope, humanity constructed a massive artificial planet, 'Arcadia,' in space. However, there were not enough resources to relocate all of mankind. Those chosen were the upper class with immense wealth and power, along with the scientists and engineers necessary to maintain the new civilization. They left Earth. And those left behind were abandoned. But something unexpected happened. As the population and industrial facilities drastically decreased, Earth's ecosystem began to recover on its own. Over decades, forests reclaimed the ruined cities, and the rivers and seas became clear once again. The humans left on Earth also survived. Instead of the massive industrial civilization of the past, they built a new society that coexists with nature. While much of their advanced technology was lost, Earth possessed something Arcadia did not. Countless biological species and pure plant seeds. Meanwhile, Arcadia flourished brilliantly. Space travel, artificial intelligence, energy, and biotechnology. Their technology advanced to a level incomparable to the Earth of the past, but spending ages in a closed artificial ecosystem caused biodiversity and pure seeds to gradually disappear. Eventually, Arcadia returned to the Earth they had once abandoned. And they say: "We wish to cooperate once again for the mutual prosperity of both humanities." However, the people of Earth remember. They remember exactly who abandoned them and left when they were in despair, thinking they would die... Earth has the life that Arcadia desires, And Arcadia has the technology that Earth has lost. After a long separation, the representatives of the two humanities sit down at a single negotiation table.

Sourcebook
Intro
In the distant future, when Earth was deemed a planet where humanity could no longer survive due to climate change and ecological collapse, the chosen ones constructed the massive artificial planet 'Arcadia' and left Earth.
Ships carrying the upper class, core engineers, and researchers headed into space, while countless people who were not chosen were left behind on the dying Earth.
However, contrary to humanity's expectations, Earth—freed from large-scale industry and population—began to recover on its own over a long period of time.
Forests covered the land once more, and the rivers and seas regained their life.
The humans left on Earth also survived, building a new civilization that coexists with nature.
Meanwhile, Arcadia also developed brilliantly.
Technologies including space travel, artificial intelligence, and biotechnology advanced beyond comparison to the past, but within the closed artificial ecosystem, pure plant seeds and biodiversity gradually vanished.
Then one day, after ages had passed.
Arcadia returned to the Earth they had once abandoned.
They possessed the technology Earth had lost, and Earth possessed the life they had lost.
Two humanities that need each other but can never fully trust one another.
Thus, after a long disconnection, the delegations of Earth and Arcadia have gathered at a single negotiation table for the first time.
