Yuln was a humanoid female Sith who served Darth Krayt's Galactic Empire during the Second Imperial Civil War. In 137 ABY, Yuln and her fellow Sith Bokar were dispatched to the planet Agamar to search for surviving enemy forces following a clash between Sith forces and an allied group of Imperial Knights and Jedi. Three days after the attack on Agamar, Yuln and Bokar were slain by Imperial Knight Azlyn Rae and Jedi Master Rasi Tuum, respectively.
