A powerful galactic guild comprised of technology firms, the Techno Union was led by its lead engineer, Wat Tambor, during the final years of the Republic. The group helped create the battle-droid armies used by the Separatists, and Tambor pledged its loyalty to Count Dooku during the Separatist Crisis. Despite its Separatist ties, the Techno Union was represented in the Republic Senate, with Gume Saam speaking on its behalf. Tambor died on Mustafar at the end of the Clone Wars.
Echo was a soldier in the Grand Army of the Republic, known for his strict adherence to orders and rules -- hence, his nickname, which was sarcastically gifted by his clone brothers. Still, Echo proved to be among the bravest clones, integral in the defense of Rishi Station and Tipoca City, and eventually achieved the rank of ARC trooper. Through tragic circumstances, however, he would become something more than a normal clone.
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.
The foreman of the Techno Union, Wat Tambor was one of the original and most fervent Separatist leaders, pledging his loyalty and his battle droid armies to Count Dooku at a pivotal meeting on Geonosis. Later in the war, Tambor was appointed emir of Ryloth. His occupation was a cruel one, in which Tambor stripped the Twi'leks of whatever valuables he could find, then bombed their villages.
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.
