Federal Army of Chorus

The Empire is a faction in Red vs. Blue consisting of hostile soldiers from the planet Chorus. They use tyranny to control the planet's society and fight against the New Republic for control over the planet.

Overview
According to Felix, an affiliate of the New Republic, after the Great War between the humans and the aliens came to a close, the outer colony of Chorus was forgotten by the UNSC and left to fend for themselves. After a while, the citizens of the planet attempted to govern themselves, but soon the Empire was formed, which attempted to take over the entire planet and put everyone under their supervision. Due to their actions, they caused a faction known as the New Republic to form, as they wanted their freedom. As a result, this led to a Civil War between the two groups on Chorus.

Trivia

 * The Empire and Project Freelancer both have ties to the UNSC. The former was deserted by the military group, while the latter was originally created to be a splinter group.
 * The 'Empire' might be a pun of the Galactic Empire, a famous faction in the Star Wars franchise.
