Umbara, known as the "Shadow World" due to the rays of its sun never completely reaching its surface, is perpetually dark. The native wildlife have adapted to survive in such gloom, making the planet perpetually dangerous. Umbara was once part of the Galactic Republic, represented in the Senate by Senator Mee Deechi. Later in the Clone Wars, the planet's loyalty wavered and the natives of Umbara allied themselves with the Separatists, bringing their extremely advanced technology to the Separatist Alliance.

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. Some even believed he was the prophesied Chosen One who would bring balance to the Force. Always pushing the limits of his Jedi training, seeking to excel and live up to his reputation, Skywalker's passion often brought him into conflict with his mentor, Jedi Master Obi-Wan Kenobi. A hero of the Clone Wars, Anakin was caring and compassionate, but suffered from a deep fear of loss that would prove to be his downfall.

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.

Rex once served the Republic on the frontlines during the Clone Wars, taking orders from Anakin Skywalker and Ahsoka Tano as first a captain and later a commander. He viewed military service as an honor, and his loyalty to the Republic and his Jedi Generals was absolute. But when Order 66 was executed, it was Ahsoka who helped to free Rex from the programming of his inhibitor chip. At the dawn of the Empire, Rex has escaped with his life but is considered killed-in-action in the eyes of the new regime. That allows him to operate in the shadows and help any clone brothers who remain separate from the Imperial ranks.

The pale and ghostly Umbarans are an extremely high tech species who have decided that the Separatists are a more worthy group to follow than the Republic. At one time represented in the Galactic Republic by the devious Mee Deechi, Umbara seceded from the Republic and joined the Separatist cause. Their advanced weaponry proved a great challenge to the clone troopers tasked with conquering Umbara.

Also known as an Impeding Assault Tank (IAT), the Umbaran crawler tank is a horrifying mechanical monster created by the advanced technology of the Umbaran people. The crawler tank is armed with blaster cannons, shield generators, and designed to have multiple redundancies to cope for heavy damage.
