|Chronological and political information|
Koong was the Imperial Governor of Roon's Tawntoom province during the early years of the Galactic Empire. He was a megalomaniac, running his own illegal operations from his fortress, including theft and hijacking. He was also an expert in political intrigue.
He amassed a small fortune after he took control of one of the lightstations in the Cloak of the Sith, purposely crashing ships that tried to travel through the dust cloud and recovering the debris for parts.
Eager to become allied with the Empire, Koong made a deal with Admiral Terrinald Screed to supply the Empire with parts in return to maintain his position of power and his freedom to do what he wanted. When Koong salvaged the Caravel, a ship belonging to Mungo Baobab, he believed the merchant was one of Screed's lieutenants. Only when Screed himself arrived to observe Koong's operation, did Koong realize he had been tricked and Baobab and his droids, R2-D2 and C-3PO, were arrested. Baobab managed to escape, inflicting damage to the lightstation and causing it to crash into an asteroid.
Desperate to prove himself to the Empire after the failure of his previous scheme, Koong determined to crush resistance in the Umboo Province. To this end, he attempted to fix the Roon Colonial Games so that his Tawntoom team beat the Umboo team and crushed rebel spirits. His attempt failed due to the intervention of Mungo Baobab.
Later, Koong used the Rooze Disease to try and poison the Umboo Province, but accidentally infected himself as well. The renowned doctor, Nilz Yomm, was captured and forced to develop a cure for the germ, but Baobab stole it and freed the doctor. Baobab made a deal to exchange the cure and the location of the Roonstone treasure for his ship and Koong's promise to leave Umboo alone. However, Screed double-crossed Koong, taking control of Roon and seizing the treasure.
Koong made an unsuccessful attempt to kill Baobab and the Imperials but succumbed to his illness before he could use the cure and he died.
