Here is the official word on the episode: 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 in “Front Runners,” airing this Saturday, October 13th at 9:30am ET/PT on Cartoon Network.
Lucasfilm has also included some trivia about the episode.
As is evident in this episode, the design of Iziz draws heavily from ancient Rome. King Sanjay Rash’s design heavily features Roman influences, included a headband that suggest gilded laurel leaves at his temples.
The look of the Onderon rebels are very much inspired by the look of the commandos in Return of the Jedi.
The droid watchtower seen in Iziz resembles a similar platform used by Rebel sentries on Yavin 4 in Star Wars, except these are elevated by repulsorlift technology as opposed to mounted on a physical stalk.
