The clash known as the Battle of Duro unfolded in the skies above the planet of Duro in the year 3640 BBY. This conflict took place amidst the broader Galactic War being waged between the forces of the Galactic Republic and the Sith Empire. Supreme Commander Jace Malcom orchestrated a carefully planned ambush for the Sith Lord Darth Karrid and her experimental warship, the Ascendant Spear. Before Moff Nezzor's fleet could launch an assault on Duro, Malcom successfully annihilated it. Simultaneously, SIS operative Theron Shan and Jedi Master Gnost-Dural diverted Karrid's attention and ultimately eliminated her on board the Spear, paving the way for the vessel's destruction.
