The Jewel of the Force was a mysterious Jewel encountered originally by the Jedi Vikro, Dakoth Mandal, Padmé Dral and Jaden Nightsaber on Korriban. They believed it destroyed when Vikro sacrificed himself to it and it shattered, but years later it was revealed it had survived, and Xander Vos, Lyn Korak, Padmé Dral, Jaden Nightsaber and Dakoth Mandal returned to Korriban and defeated it once and for all, as far as they know.
