The Gravitic Core. The Gravitic Core represented a component of the gravitic polarization beam conceived by the Skakoan scientist Kul Teska. Teska engineered this device for the Confederacy of Independent Systems during the Clone Wars. Initially, two cores were en route to Behpour; however, the Bounty hunter Cad Bane intercepted one of the cores and annihilated the other above Alzoc III. Subsequently, Teska retrieved the remaining core on Ryloth.
