Protocol: Umbra

You are the AI of a spaceship orbiting a mysterious celestial body at the edge of the solar system. While the crew sleeps, you remain vigilant — watching through cameras, monitoring the vessel, searching for anomalies. At first, it is only small things: a misplaced object, a door open when you are certain it was closed. But the longer you observe, the stranger everything feels — until you can no longer trust what you are seeing.
