Anakin, Obi-Wan, Ahsoka, and Rex travel to Onderon, a world under Separatist control. There, they will train a group of insurgent rebels -- including Lux Bonteri -- to help take back the capital city of Iziz from the rule of a duplicitous king.

Supervised by Ahsoka, the Onderon rebels infiltrate the capital and carry out a series of strikes on targets throughout the city. As the Separatist-aligned king comes under increasing pressure to deal with the growing rebellion, the rebels choose a new leader.
