Force Harvester
this unusual piece of ancient technology was believed to have been lost on Raxus Prime many centuries before the Battle of Geonosis, and eventually buried under all the debris which littered the planet's surface. It was originally created during the time of the Great Sith War, as the power source for the weapon known as the Dark Reaper. The Harvester was designed to drain the energy of the Force from any living being, regardless of whether they were Force-sensitive or not. Around the time of the Battle of Geonosis, Count Dooku began a massive excavation effort to locate the Harvester. Unfortunately, the Jedi Knights and a task force of the Army of the Republic discovered Dooku's base of operations and bombarded it before the Harvester could be recovered.
