Section 31 Headquarters was a space station used during the mid-23rd century by the covert intelligence division, Section 31, that had once been a penal colony. It was the base for Section 31's AI system Control, which analyzed any threats Starfleet faced. In 2257, Control was infected by an AI program from the future. As a result, it achieved sentience and set out to eliminate all organic life in the Galaxy. It killed all the crew on the station, taking power, gravity, and life support offline. Measures roughly 8-inches long.
