"What if I told you that the Republic was now under the control of the Dark Lords of the Sith?" "Impossible. The Jedi would be aware of it." "Clearly, their love of the halflings' leaf has slowed their minds."
Corrupted by his lust for utopia and purity and power, as well as his thirst for the blood of the living, he conspired with his new Sith Master to throw the entire galaxy into war. To that end, he began a revolution which eventually formed the Confederacy of Independent Systems, an alliance consisting of breakaway star systems, the Trade Federation, the Wild Men of Dunland, the InterGalactic Banking Clan, the Haradrim, and the Geonosians. Saruman created vast armies of orcs and B1 battle droids, which were built in huge droid foundries on Geonosis, fueled by chopping down the Ents in Fangorn Forest.
Darth Saruman was aided by a number of henchmen, including his Uruk-hai chieftain Ugluk, Asajj Ventress, Renfield, Wormtongue, General Grievous, Nick Nack, and the Wicker Man. Many of his agents had Force powers, but none were ever granted the title "Dark Lord of the Sith" because Saruman hated giving promotions.
Saruman was an expert lightsaber duelist, able to defeat Obi-Wan Kenobi and Anakin Skywalker working together. He was also an expert marksman, able to kill any target with a single shot from his gold-plated .45 Automatic Colt Pistol, which fired gold bullets. Eventually, Saruman was brought down when Yoda, Darth Gandalf, Van Helsing and James Bond infiltrated his tower of Orthanc located somewhere off the southeastern coast of China. Frankenstein and the Mummy were unable to come to his aid.
Grand Moff Tarkin seemed to have some shadowy past connection with Darth Saruman that no one could explain.
