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, 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.
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.
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. His loyalty to the Republic and his Jedi Generals was absolute, but even this dedicated veteran soldier found himself plagued by doubts as the Clone Wars claimed more lives and brought ruin to more worlds.
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.
