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.
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.
Saw Gerrera was a loyal follower of King Ramsis Dendup, the benevolent monarch of Onderon who attempted to keep his world apart from the tensions of the Clone Wars. Saw believed firmly in independence, and did not want to see his planet thrust into galactic warfare. But Dendup was ousted by King Sanjay Rash, who committed the world to the Separatist cause. Saw was one of the fervent young loyalists who refused to acknowledge Rash's rule, and openly rebelled against the crown. He and his sister Steela were cast out of the walled city of Iziz and forced to live in ruins amid the jungles of Onderon, but formed a rebellion.
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 under mysterious circumstances attributed to the Republic. Lux filled her position in the Separatist Senate, representing his home planet of Onderon.
Clone Captain Rex served the Republic during the Clone Wars, often taking orders from Anakin Skywalker and Ahsoka Tano. He viewed military service as an honor, and he always completed his mission. Fond of using two blaster pistols at the same time, Rex customized his armor with distinctive blue markings.
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.
