Also known as the Second Sith War and the War of the Star Forge, the Jedi Civil War is one of the darkest eras in galactic history. Three centuries ago, a pair of idealistic young Jedi named Revan and Malak led thousands of followers into the Outer Rim to do battle with an invading Mandalorian army. The Mandalorians were defeated‒and Revan and Malak returned to the Republic not as heroes, but as conquerors.
Declaring themselves Dark Lords of the Sith, Darth Revan and Darth Malak began the ruthless subjugation of Republic worlds in the Outer Rim. The Jedi Council, which had been loath to take action against the Mandalorians, assembled an army to bring the traitors to justice. Darth Revan was captured during an attack by the Jedi Knight Bastila Shan and eventually turned back to the light side. Together Revan and Bastila defeated Malak, ending the threat.
