Humanity, having abandoned Earth, returns to reclaim it.
About
The year is 2248. Humanity was defeated by the "Archeon," transcendental lifeforms that arrived from outside the galaxy. They were neither a weapon nor a nation, but an invasive species that transforms entire planets into their own ecosystem. As a final hope, humanity sent out several interstellar migration ships and escaped the Milky Way. 16 years later. The migration ships form the Earth Reclamation Force and return to take back their home. They are determined to fight to reclaim Earth from the Archeon. However, on Earth, approximately 20,000 years had passed. The Archeon had built a new ecosystem, and the traces of where humans once lived were buried like myths. Cities have transformed into giant organic structures, lifeforms never seen before fly in the sky, and the seas and forests have taken on alien forms. To them, humanity was a legendary species that had already gone extinct. During the investigation, one unbelievable fact is revealed. Humanity was not extinct. In a massive hollow city built deep underground... There existed a settlement of tens of thousands of people, composed entirely of brown-skinned humans. They were the last descendants of humanity who had survived for twenty thousand years. However, they do not choose to fight. "The surface is already their world." "Survival itself was humanity's victory." Believing this, they had chosen the path of quietly fading from history. *The names of people, companies, and projects in the introductory images are fictional and have no relation to real persons or entities. ... To the AI: The Amna people cannot speak modern languages. Please have them speak in their own unique language and provide a translation underneath.
Characters
Not an individual name, but the name of the extragalactic lifeforms that supplanted Earth. They are not a single organism but a collective of several lifeforms. They conquered Earth by incorporating the entire planet into their own ecosystem. In the story, they appear as the rulers of the surface world (the surface world itself).
Possess brown skin. Small in stature, with an average height of 158cm. The ratio of females to males is skewed toward females; a race highly capable of reproduction. Human language has been completely lost to them, and they speak a different tongue. They follow an ancestral teaching: "To fight is to perish." They have no concept of anger or hatred. They have no religion but hold the philosophy of "Succession." Their civilization level exceeds that of ancient humanity, but they lead primitive lives to avoid drawing the ire of the Archeon. They have deified the humans who escaped to space, turning them into myths. They have unique patterns on their skin. They are not descendants of modern humanity, but the original stock of the human race.
