Rather than use flesh-and-blood warriors, the Separatists prefer mindlessly loyal soldiers that are easily controlled. The soulless ranks of their armies are dominated by tall, thin B1 battle droids built as mechanical imitations of their Geonosian designers. Battle droids can be controlled by centralized command centers such as the Trade Federation’s enormous Droid Control Ships, or programmed for independent action. They often suffer programming glitches that manifest as personality quirks. Battle droids are dim-witted and no match for clone troopers or Jedi, but they weren’t designed to be smart – they were designed to overwhelm Republic civilians through sheer numbers, something they do very effectively.
An enormous improvement over the standard battle droid, commando droids are elite warriors too expensive to produce in huge numbers. These stealthy yet powerful warriors are tougher and faster than their clanker cousins. Complex engineering gives them incredible agility, while advanced processors let them think fast on their nimble feet.
An ambitious, ruthless proponent of military power, Wilhuff Tarkin became a favorite of Supreme Chancellor Palpatine and rose rapidly through the Imperial ranks. Shortly after the Empire's creation, he was put in charge of the construction of the Death Star. Tarkin saw the Death Star as a way to crush all dissent to the Empire's rule -- fear of the station's planet-killing superlaser would keep the galaxy's star systems in line. He demonstrated the station's power by destroying Alderaan, but died soon afterwards when the Death Star itself was destroyed.
The Confederacy of Independent Systems, also known as the Separatist Alliance, was a collection of star systems and corporate titans that left the Republic and fought for independence against the Republic’s clone armies and Jedi Knights. The charismatic former Jedi Count Dooku was the Alliance’s political leader, while its military power came from credits and assets donated by powerful galactic trade groups. No one suspected that the Alliance was actually a tool of Darth Sidious, who had engineered the Clone Wars as part of a Sith plot to rule the galaxy.
A gruff and battle-hardened Jedi as well as senior member of the Jedi council, Even Piell was bigger than life though he was small in stature. Highly skilled with a lightsaber and a great warrior, Piell was always willing to charge into battle. During the Clone Wars, he was tasked with some of the most crucial missions, protecting vital Republic territory and information.
