A king, a male human, ruled the Kingdom of Shu-Torun throughout the Imperial Era. He was also the father of Princess Trios along with her older siblings, Monthan and Hollian. Approaching death due to his advanced age by the time of the Galactic Civil War, the king officially designated Monthan as the heir to the throne of Shu-Torun and established Hollian's future position as the celebrant warlord of the War-Faith.
During Darth Vader's visit to Shu-Torun, the Sith Lord was targeted in an assassination plot devised by the king, who aimed to eliminate the Galactic Empire's Sith enforcer. The king intended to sacrifice Trios in order to kill Vader during the Shu-Torun counter-bore waltz, but the Dark Lord of the Sith overcame the attempt on his life. Consequently, the king, along with his two eldest children and his bodyguards, met their end at the hands of the Sith Lord's assassin droids, 0-0-0 and BT-1. As the only remaining member of the Shu-Torun royal family, Trios ascended to the position of monarch of Shu-Torun, succeeding her father. Utilizing the Force, Vader placed the deceased king's crown upon the head of the new queen, informing Trios of her new responsibilities as a vassal under the Empire's control.
