Treyz Manech was a male Human Imperial commander serving on the Outer Rim Territories world of Troska. Originally a lieutenant, Manech was removed from duty aboard an Imperial-class Star Destroyer after an attempt to commandeer the ship. Manech nonetheless sought advancement through the Imperial heirarchy—an aspiration made difficult by his corrupt superior on Troska, Commander Sev Buzk. Although his attempts to progress through the chain of command had been futile, Manech saw an opportunity to exploit both Buzk's illicit activities and his antagonistic relationship with the planet's ruling entity, the Kyber Royal Family.
