The Kwejian system was a formerly inhabited planetary system. The system had one star orbited by at least one planet, which was named Kwejian. This planet was home to the humanoid Kwejians, sea locusts, and trance worms.
This system was the closest one to Deep Space Repair Beta Six, which was several light years away.
In 3190, the Dark Matter Anomaly passed through the system, destroying Kwejian and its moon. (DIS: "Scavengers", "Kobayashi Maru", "Anomaly (DIS)")
