Oznek, a world found within the Outer Rim Territories' Cademimu sector, was classified as a planet.
The sentient Toma species originated on Oznek, making it their homeworld. In 22 BBY, during the Clone Wars, it was believed that Oznek housed a droid command center belonging to the Confederacy of Independent Systems. To destroy this alleged command center, the Galactic Republic dispatched a squad of clone troopers under the leadership of Clone Sergeant Banks. Banks thwarted Commander Griebs Kishpaugh's scheme, which involved the clone trooper Ghost attempting to sabotage the mission.
