A young native of Onderon, Steela and her brother Saw were members of the insurgency that opposed the rise of King Sanjay Rush, and Rush's alignment of the planet to the cause of the Separatists during the Clone Wars. Not as boisterous or as outspoken as her brother, Steela was nonetheless firmly dedicated to the cause of Onderonian independence. She was not one for impassioned speeches or political rhetoric. These were not her areas of expertise, and she felt far more comfortable peering through the macroscope of her blaster rifle. A crack shot, Steela racked up an impressive number of droid kills with precise headshots fired from the cover of canopy jungle.

In its earliest ages of civilization, Onderon was a world marked with savage jungles that were filled with dangerous creatures. To survive, the primitive human inhabitants of the planet protected themselves behind the walls of fortified settlements. Over time, these grew to become enormous walled cities, like the planet's capital, Iziz. In the modern era, during the time of the Clone Wars, the planet's monarch King Sanjay Rash allied Onderon to the Confederacy of Independent Systems. Many Onderonians, however, refused to recognize the legitimacy of Sanjay's rule -- they preferred the neutral stance championed by former monarch Ramsis Dendup, whom Rash ousted.

The son of Separatist Senator Mina Bonteri, Lux was young, idealistic, and skeptical of the aims of the Republic and the Jedi Knights. His father was a fervent supporter of the Separatists, and was killed by clone troopers on Aargonar. Lux did not know what to make of Ahsoka Tano and her visit to Separatist space. After a failed peace overture begun by Mina extended to the Republic, Lux’s mother died, assassinated on Count Dooku’s orders. After making an ill-fated effort to avenge her by killing Dooku, Lux joined the anti-Separatist resistance on his homeworld of Onderon. After the rebels defeated the Separatists, Lux became Onderon’s Republic Senator.

Discovered as a slave on Tatooine by Qui-Gon Jinn and Obi-Wan Kenobi, Anakin Skywalker had the potential to become one of the most powerful Jedi ever, and was believed by some to be the prophesied Chosen One who would bring balance to the Force. A hero of the Clone Wars, Anakin was caring and compassionate, but also had a fear of loss that would prove to be his downfall.

Ahsoka Tano, a Togruta female, was the Padawan learner to Anakin Skywalker and a hero of the Clone Wars. Alongside Anakin, she grew from headstrong student into a mature leader. But her destiny laid along a different path than the Jedi.

During the Clone Wars, the Galactic Republic had little recourse with worlds that willingly sided with the Separatist Alliance -- the rules of engagement enforced by the Senate and the Jedi Order contained the battlefield to contested worlds. But what of planets where the Separatist banner did not garner unanimous support among its populace? When an insurgency on Onderon refused to recognize the legitimacy of its monarch and began a rebellion to oust both the king and the Separatist influence on the planet, Anakin Skywalker saw an opportunity: If the Jedi could train and equip the rebels on Onderon, these freedom-fighters would keep the Separatists occupied during the Clone Wars.
