For millennia, the moon has been humanity's silent companion. But it is not a world of rock and dust. It is a lie. When seismic quakes crack open its surface, they reveal the truth: the moon is an ancient alien construct, an observation station built to monitor Earth's evolution. An elite international team ventures inside, only to awaken its dormant systems and a terrifying fail-safe protocol. The station's creators, the long-extinct Obsidians, were not just observers but custodians of a delicate cosmic balance. Now, their automated legacy has put humanity on trial. Faced with global annihilation, the team must decipher the secrets of their silent guardians and prove humanity is worthy of survival before the moon itself becomes our executioner.
