Three years ago, humanity was saved. In a last-ditch effort to reverse a planetary climate crisis, a coalition of world leaders deployed atmospheric nanobots, a revolutionary technology that could reverse-engineer the planet's natural trachejory. The nanobots worked flawlessly, repairing the ozone layer and pulling the planet back from the brink of environmental collapse. But now, the miracle has become a nightmare. Reports of strange weather, erratic planetary data, and a sudden, violent atmospheric collapse are flooding in. The nanobots, once heralded as saviours, have seemingly malfunctioned, undoing their work with terrifying speed. With the planet cooling at an alarming rate and its protective magnetic field weakening, society begins to unravel. As chaos erupts in the streets, a trio of scientists are the only ones who can uncover the truth. Once the heads of the very department that deployed the nanobots, they were cast aside when their work was deemed complete. Now, a desperate government must turn to them one last time. In a world succumbing to an end, they must race against time to solve the greatest puzzle in human history: is this a catastrophic glitch, a final act of a dying planet, or has the ancient AI come to a horrifying conclusion of its own? The nanobots gave humanity a second chance. Now they are taking it away.
