By the twenty-third century, humanity had long since left Earth behind. Colonies stretched across dozens of star systems, and Terrans believed themselves an expansive and unchallenged civilization. For a time, it seemed nothing could slow their rise.

That belief ended when the Anirans and the Cetians revealed themselves. They were not strangers from distant space, but ancient branches of humanity that had grown in parallel, hidden from Terran sight. The Anirans, guardians of harmony and tradition, and the Cetians, architects of survival and resilience, unveiled a history far deeper than Earth had ever known. Their arrival transformed Terran science, politics, and identity, stirring awe, doubt, and unease.

To preserve peace, the great powers of Earth joined with the Cetian Consortium and the Aniran Omnium to form the Council of the Core and the Mutual Defense Force. It was a first attempt at true interstellar unity, yet suspicion still lingered. Centuries of distance had left wounds not easily healed.

And beyond the mapped stars, something else is stirring. Rumors tell of a hostile presence waiting in the dark, silent and watching.

As alliances strain and rivalries return, the three branches of humanity face a choice. Stand together against what lies beyond, or fall divided before it.
