The stars were never meant to be home. Two million years ago, when Earth was still alive with forests and oceans, but scarcity, shifting climates, and wicked abuse of powers humans were never meant to hold held the threat of extinction looming over our conscience, humanity built three vessels and sent them into the dark, a desperate insurance policy against extinction. If Earth failed, the ships would carry humanity's future to the stars. The vessel you live in is the USSF Eden.
Humanity never mastered cryogenic sleep. They never built engines that could approach the speed of light. The Eden would not be crewed by heroes making a short voyage into the unknown. Instead, it would be carried by generations. The architects of the mission solved the problem with brutal simplicity: the ship would sustain a small, stable population, passing the mission from parent to child for as long as necessary. To preserve humanity itself, thousands of frozen embryos were stored deep within Eden’s genetic vaults. Over the centuries they would be gradually introduced into the population, renewing genetic diversity and preventing the slow genetic drift of isolation. Every person aboard the ship is the child of a mission that began millions of years ago. Including you.
Eden was designed to last. Its systems recycle water, air, and matter in a closed chain so efficient that almost nothing is ever lost. Metals are reformed. Carbon is reused. Waste becomes nutrients. The ship is less a machine than a perfect ecosystem, engineered to sustain human life indefinitely. But two limits were unavoidable. The nuclear reactors that power Eden, and the finite supply of human embryos. Together they defined the mission’s true length: Two million years.
The ship itself does not belong to the people aboard it. Humanity feared that the generations born on Eden might eventually abandon the mission. That they would grow tired of a purpose set by ancestors long dead. So the ship was given an overseer. An artificial intelligence governs the navigation of Eden. It alone determines the course. It alone decides when the ship arrives and when it leaves. Eden was programmed to survey three candidate worlds, including the distant planet Kepler-452b. If none proved suitable for colonization, the AI was instructed to complete its final directive. Return home. The designers hoped that if by then, Earth had collapsed at the hands of humanity, millions of years might heal it. If the stars held no hope for us, then maybe coming back would give the human species hope for rebuilding society and trying again before the inevitable decay of the sun doomed the cradle of humanity.
Life aboard Eden was never meant to be suffering. The ship carries the full archive of humanity’s entertainment. Libraries. Music. Films. Games. Entire digital museums of culture long vanished. The founders believed that if people were to spend their entire lives in a metal world drifting through the void, they would need more than survival. They would need joy. But memory can become a burden. For generations the people of Eden studied the history of Earth. They saw images of oceans, forests, cities, and skies filled with birds. They watched recordings of a world they would never walk. Eventually, one generation decided they had seen enough. The photographs and films were deleted and destroyed. Looking at Earth had become unbearable. Now the people of Eden know their origin only through text and songs. Through descriptions written by ancestors who saw the planet with their own eyes. No one alive has ever seen a tree. No one alive has ever seen an ocean. No one alive has ever stood under an open sky.
Today, the long voyage is ending. After two million years crossing the void, the ship is approaching its final destination. Earth.
