The Supreme Guard represented the elite tier of the Republic Military. During the period known as the Cold War, these highly trained individuals functioned as the dedicated protection detail for the Galactic Republic's leader, the Supreme Chancellor.
Drawn from the most skilled and dedicated members of the Republic armed forces, these soldiers were entrusted with the critical mission of safeguarding the Supreme Chancellor. To avoid disrupting the Chancellor's daily activities, they typically wore plain clothes. However, these guards were always on alert, maintaining a nearby force of heavily armed and armored soldiers ready to rapidly respond to any threat against the leader of the Galactic Republic.
Becoming one of these elite protectors involved demanding trials that tested a recruit's skills. However, skills alone were not enough to get accepted into the Supreme Guard. Potential members had to demonstrate a willingness to give their own life for another. Because of this, each member of the Guard had a story of sacrifice and selflessness, whether it occurred in the line of duty or elsewhere. These stories defined many within the Supreme Guard.
During the Cold War, after the Sith Empire initiated open conflict with the Republic following the invasion of Corellia, Jedi Master Jun Seros was defeated by the Grand Champion of the Great Hunt. This defeat allowed Darth Tormen to examine Seros' effects and determine the Supreme Chancellor's location. Tormen discovered that the Chancellor was aboard the Founder and was being guarded by the Supreme Guard. Consequently, a bounty hunter was tasked with infiltrating the ship, overcoming the guards, and confronting Chancellor Dorian Janarus.
