Warren Sedoru was already one of the most acclaimed Jedi Knights of the order when the Sith Empire attacked the Republic at Korriban. He was one of the first Jedi to lead a counterattack against Imperial forces and scored several early victories against them. The price of these triumphs was high, however.
Records indicate Warren was critically injured over a dozen times in battles from Alderaan to Yavin Four. Although he survived these near-deaths without need of cybernetic replacement parts, Warren's connection to the Force began to diminish. When the Republic signed the Treaty of Coruscant, Warren dedicated himself wholeheartedly to peace. He gave up his rank as Jedi Knight and became a Padawan to Master Tol Braga.
