The Treskov system, found within the Deep Core, was a star system that orbited the star known as Treskov 115-W. During the Galactic Civil War, the Imperials made use of this system. After its abandonment, the New Republic employed the system to inflict heavy losses and decimate the forces of the Yuuzhan Vong on Ebaq 9, which is a moon orbiting the planet called Ebaq within the system.
