Troska, a world covered in forests, existed as a planet situated in the Troska system found in the Outer Rim Territories.
On Troska, there was a small Imperial base that received reluctant backing from the governing Kyber Royal Family. Among the sites on Troska was Refinery Six-Two-Two, and Sev Buzk, Treyz Manech, together with Kelmont were some of the Imperial officers posted there.
During the time of the Galactic Civil War, Manech paid Boba Fett to overthrow the Kyber Monarchy, which led to the Battle of Troska. As Imperial troops neared the palace, King Natas Kyber offered Fett a bribe to save his life, rendering the assault aimed at preventing Fett from assassinating the King futile, and a substantial portion of the Imperial contingent was decimated.
After this conflict, Manech received a promotion to become the sector commander.
