The Sith temple was located in the heart of the city of Kesiak on Thule, during the era encompassing both the Clone Wars and the Dark Reaper crisis. It was at this location that the Confederacy of Independent Systems, led by Count Dooku, endeavored to bring the Dark Reaper back online; this was a very old Sith superweapon, created thousands of years earlier at the Thule armory. In the course of the Battle of Thule, Anakin Skywalker advanced through Kesiak to reach the Sith Temple, where he ultimately annihilated the Dark Reaper with a TX-130 Saber-class fighter tank.
