- "So, General Grievous, we meet at last. In the name of the Republic, I—urrrk!"
- ―Sannen before his death.
A Force-sensitive male, Sannen was trained by the Jedi Order in the ways of the Force, eventually attaining the rank of Jedi Master. When the Clone Wars erupted between the Confederacy of Independent Systems and the Republic, Master Sannen took up the mantle of General in the Grand Army of the Republic, leading clone troopers against the Separatist Droid Army.
During the war's first year, Sannen was dispatched to the moon of Parein II 4 to lead the battle against the Separatists there. While on the ground, Sannen found himself face to face with the Supreme Commander of the Confederation military, General Grievous. As Sannen confidently prepared to engage the general, one of Grievous' IG-100 MagnaGuards jabbed Sannen in the throat with an electrostaff, killing him.
