The Quesna system, a star system found within the Toblain sector of the Outer Rim Territories, housed the Quesna Base and a planet situated behind it.
The Galactic Civil War saw this system as the location of the Imperial Cargo Facility 2, known as Quesna Base. It was at this station that Emon Azzameen faced arrest and imprisonment for purported "crimes against the Empire," ultimately leading to his rescue by Ace Azzameen.
