A legendary Jedi Master, Obi-Wan Kenobi was a noble man and gifted in the ways of the Force. He trained Anakin Skywalker, served as a general in the Republic Army during the Clone Wars, and guided Luke Skywalker as a mentor.
In the final days of the Republic, the galactic government had grown so huge and corrupt that any attempt at change required radical thinking and extreme actions. Outlying systems that saw no benefit from being part of the Republic despite paying heavy taxes, began to rebel. This undercurrent of disgust towards Coruscant was seized by a charismatic leader, Count Dooku. The former Jedi rallied together these worlds in a Separatist movement that saw the departure of thousands of systems from the Republic. When Dooku's alliance was secretly backed by corporate titans that offered their unlimited droid armies to the cause, the Separatists emerged as a major threat to the Republic, and the galaxy tipped towards full scale war.
At the time of their introduction, the Republic clone troopers represented the future of galactic warfare. Far superior to battle droids, the clone troopers formed the backbone of the Republic's new military that waged war against the forces of the Confederacy of Independent Systems. So symbolic were they of the times, the galaxy-wide conflict that saw their debut took its name from their ranks: the Clone Wars.
Ringed by numerous moons, the remote sanctuary of Utapau is a planet pitted with enormous sinkholes. Its windswept surface is dry and desert-like, but deep in the porous crust, at the bottom of the sinkholes are pools of life-giving water. Many of the sinkholes on one of the planet's small continents are lined with intricate cities that stretch deep into caves and crevices beneath the planet's surface, as well as mining operations that seek to uncover valuable minerals from the planet's depths.
General Grievous was a brilliant Separatist military strategist and a feared Jedi hunter, known for his ruthlessness and hacking cough. His body itself was a weapon, allowing him lightning quick strikes and devastating blows. But he was also quick to run from a fight, a tactic that worked until one final meeting with Obi-Wan Kenobi.
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.
