The Sith Nova Holocron was a device that Count Dooku planned to use to locate Jedi Padawans in order to turn them to the dark side of the Force. The Holocron was broken into three pieces, each located on a different planet. One piece was located on Tatooine, another on Christophsis, and the third piece on Rodia. Dooku obtained the part on Tatooine, but was stopped on Christophsis by Aayla Secura and an unknown Padawan, and on Rodia by Kit Fisto and the same Padawan.
