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.

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.

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.

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.

Bail Organa, a member of Alderaan's royal family and the planet's representative to the Republic Senate, earned respect on Coruscant for his honesty and his commitment to justice. Prior to the Clone Wars, Bail served alongside Senator Padmé Amidala as a member of Chancellor Palpatine's Loyalist Committee. The two became close friends, and recruited like-minded allies to prevent Palpatine's alarming grabs for power. At the end of the war, Bail Organa adopted Padmé's daughter Leia and raised her as an Alderaanian princess. While representing Alderaan in the Imperial Senate, he worked secretly with allies such as Mon Mothma and Ahsoka Tano to assist rebel cells scattered across the galaxy, working towards the day that a unified Rebellion could emerge. Bail died when the Death Star destroyed his homeworld.

Yoda was a legendary Jedi Master and stronger than most in his connection with the Force. Small in size but wise and powerful, he trained Jedi for over 800 years, playing integral roles in the Clone Wars, the instruction of Luke Skywalker, and unlocking the path to immortality.
