Mimban’s valuable minerals have made this muddy world a battlefield since the Clone Wars. Then, the Republic was fighting Separatist droids; now, the Imperial Army seeks to destroy Mimbanese insurgents. After getting kicked out of the Imperial Academy, Han Solo found himself dumped on Mimban as a mudtrooper. While there Han met an Imperial prisoner named Chewbacca, an encounter that would change his life.

Formally known as Imperial swamp troopers, mudtroopers are part of the Imperial Army, whose infantry is gradually being phased out in favor of stormtroopers. Mudtroopers wear partial armor, augmented with respiratory gear and sealed bodysuits for combat in unhealthy environments such as Mimban. Han Solo served as a corporal with the 224th Imperial Armored Division, a new incarnation of the Mud Jumpers of the Clone Wars.

A stout two-legged walker, the All Terran Defense Turret, or AT-DT, is a mobile artillery piece designed to protect infantry and Imperial installations during ground combat. The AT-DT’s head is protected by extra layers of armor plating and shielding against artillery flashback.

The Galactic Empire ruled for years through fear, intimidation, and tyranny. With a mighty military force including stormtroopers, spy technology like probe droids, and the planet-destroying Death Star, Emperor Palpatine’s regime seemed unstoppable and permanent. But some dared to strike back…

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.

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.
