An engineer of the Galactic Empire was stationed on the Executrix, an Imperial I-class Star Destroyer, during the conflict close to the Gulf of Tatooine. After this conflict, the engineer communicated to Wilhuff Tarkin, a Moff and the commanding officer of the Executrix, that the Star Destroyers named Compliant and Enforcer had emerged from hyperspace originating from the Imperial marshaling station located at Pii.
James Luceno initially referenced this technician in his Tarkin novel, published in 2014.
