An officer of the Galactic Empire, specifically holding the rank of major, was assigned command of a spice mine that produced medicinal substances. This facility was situated on Naboo, a planet located in the Mid Rim, throughout the Imperial Era. In the year 3 BBY, Brel Ti Vorne, a human who worked as a miner, told Leia Organa, the Princess from Alderaan, that the major intended to sell the mining tools that she had provided to him and his fellow workers, in order to gain personal profit. This revelation greatly angered Organa, leading her and Queen Dalné of Naboo to visit Quarsh Panaka, a Moff, at his chalet. They informed the Moff about the crimes being committed by the major.
Leia, Princess of Alderaan, a young-adult novel from 2017 penned by Claudia Gray, featured a reference to the Imperial major.
