Senator Bail Prestor Organa of Alderaan and Master Obi-Wan Kenobi of the Jedi Order followed the trail of the Sith to Zigoola during the Clone Wars (using information supplied to Organa by the Friends of the Republic), and Kenobi was subjected to intense mental attacks emanating from a Sith holocron inside the temple. When Bail smashed the holocron, the attacks ceased, and the temple was destroyed, denying the Jedi Council the opportunity to study the Sith artifacts.
