When the Separatist Crisis between the Galactic Republic and the Confederacy of Independent Systems erupted into a conflict on Geonosis, Master Du answered Master of the Order Mace Windu's call-to-arms by flying to the dust-covered world. As part of Windu's strike team assembled to rescue Jedi Obi-Wan Kenobi, Anakin Skywalker and Senator Padmé Amidala from execution by the Confederacy leaders, Du landed on the plains of Geonosis outside the Petranaki arena. While her comrades attacked the arena from the grandstands, Master Du delved deep into the catacombs. Amidst the damp quiet of the insect-constructed facility, was the first Jedi to encounter the monstrous General Grievous, a Kaleesh cyborg who was poised to lead the Separatist Droid Army in the coming Clone Wars. Wielding her lightsaber against Grievous' electrostaff, Du fought valiantly but was overpowered and killed by the General. Collecting her lightsaber as a trophy, Grievous left her body where it laid, his existence remaining a secret from the Republic until he was ready to unleash his full might on the Grand Army of the Republic.
Behind the scenesEdit
This Jedi was the creation of artist Joe Corroney, who modeled her after fellow artist Jan Duursema, from whom the character also takes her name. The name originally appeared only on Corroney's website, and was thus not part of the canon. This changed after the mention in Unknown Soldier: The Story of General Grievous, which made the name canonical.
