The Third Earthโลกที่สาม

The 99 Soulborn—cloned humans conceived in the final hours of a dying cosmos—journeyed across the void until they reached a new planet, which they christened "The Third Earth." Over the vast eons since their arrival, they meticulously shaped this once-barren world, seeding its oceans and landscapes with carefully engineered life-forms derived from their advanced genetic repositories. The Soulborn endeavored to replicate an ideal ecosystem, transplanting creatures from their past and introducing entirely new species to forge a balanced biosphere.

These near-immortal beings, whose knowledge and lifespans rival those of mythic gods, settled on a colossal island measuring roughly 7.7 million square kilometers, concealed from the outside world by a sophisticated spatial distortion. At the island's core stands Eden, a walled metropolis surpassing even the grandest achievements of the Soulborn's former home, the Second Earth. Within Eden's towering walls, climates are controlled with precision, warp-gate technology facilitates instantaneous travel, and architecture seamlessly melds with nature through advanced bioengineering. This urban marvel embodies the pinnacle of human civilization as guided and enhanced by Soulborn ingenuity.

Encircling Eden lies a broad Experimental Zone, featuring modern-day technological amenities such as automated vehicles, digital networks, and high-tech infrastructure—yet still overshadowed by Eden's near-futuristic wonders. For millions of years, this zone has served as a vast laboratory where newly engineered species—human and otherwise—undergo extensive adaptation trials. Only those life-forms that demonstrate true harmony with The Third Earth are eventually granted passage beyond the island's shores.

On the far side of the ocean, multiple continents remain in a medieval phase, ruled by feudal lords and relying on rudimentary crafts and agrarian systems. Humanity on these continents traces back merely two hundred thousand years, introduced by the Soulborn to populate the wilderness that lacked a natural evolutionary pathway toward Homo sapiens. As a result, these societies progress at a measured pace, unaware that an immense island—brimming with advanced technology and hidden behind a spatial anomaly—lies beyond their horizon.

In truth, no explorer from the medieval realms has ever laid eyes on the island. One Soulborn, gifted in manipulating time and space, established a distortion field around the seas, causing any approaching vessel or ray of light to be diverted elsewhere. Thus, the island remains a myth-shrouded mystery, despite its vast size. Meanwhile, the Soulborn watch vigilantly from Eden, intervening only when the equilibrium of life they've fostered stands at risk. Their enduring mission is to refine and protect the tapestry of existence on The Third Earth, ensuring that the legacy of creation they once salvaged can flourish anew.
