The Khonji system existed within the Outer Rim Territories, and it was situated in proximity to the Brunet system.
Within this system, on its seventh planet known as Khonji Seven, the Galactic Empire maintained a testing facility in 1 BBY. This location was scheduled to participate in trials for Imperial bioweapons Project I71A; however, the materials intended for delivery aboard the Star Destroyer called Vector suffered a containment failure, transforming the entire ship's personnel into beings devoid of reason.
