At the time of their introduction, the Republic clone troopers represented the future of galactic warfare. Far superior to battle droids, the clone troopers formed the backbone of the Republic's new military that waged war against the forces of the Confederacy of Independent Systems. So symbolic were they of the times, the galaxy-wide conflict that saw their debut took its name from their ranks: the Clone Wars.

A noble order of protectors unified by their ability to tap into the power of the Force, the Jedi Order were the guardians of peace and justice in the Galactic Republic. The age of the Jedi would end, however, due to a nefarious plot by the Sith Lord Darth Sidious.

A beautiful jewel of a world with immense crystalline formations, Christophsis was the site of repeated and heated battles in the Clone Wars. A blockade of Separatist vessels trapped a Senate relief mission behind enemy lines, necessitating a special Republic task force with experimental starship technology to scatter the blockade. This precipitated a full scale Separatist invasion of the planet, made possible by a traitor within the clone trooper ranks. In the end, the Republic was able to turn the Separatist invasion, and guard the planet from future incursions.

For over a thousand years, the Galactic Republic stood firm as a democratic union that governed the galaxy. The Republic was governed by the Galactic Senate, consisting of elected officials from each system and world, and Jedi Knights served as peacekeepers. With the rise of Supreme Chancellor Palpatine, however, the Galactic Republic -- and democracy -- would crumble.

A harsh rocky world less than a parsec away from Tatooine, Geonosis is a ringed planet beyond the borders of the Galactic Republic. Its uninviting surface is made up of harsh, rocky desert, and the creatures that evolved on Geonosis are well equipped to survive in the brutal environment. The most advanced lifeform are the Geonosians, sentient insectoids that inhabit towering spire-hives. The Geonosians maintain large factories for the production of droids and weapons for the Separatist cause in the Clone Wars. After the Clone Wars, the Empire chose Geonosis as the construction site of the first Death Star, restricting travel to the system and sterilizing the planet’s surface.

Rather than use flesh-and-blood warriors, the Separatists prefer mindlessly loyal soldiers that are easily controlled. The soulless ranks of their armies are dominated by tall, thin B1 battle droids built as mechanical imitations of their Geonosian designers. Battle droids can be controlled by centralized command centers such as the Trade Federation’s enormous Droid Control Ships, or programmed for independent action. They often suffer programming glitches that manifest as personality quirks. Battle droids are dim-witted and no match for clone troopers or Jedi, but they weren’t designed to be smart – they were designed to overwhelm Republic civilians through sheer numbers, something they do very effectively.
