A Separatist fortress existed on the celestial body Celes IV throughout the duration of the Clone Wars. Because orbital bombardment was ineffective due to the fortress's protective shields, a battle transpired on Celes IV's surface between the Confederacy of Independent Systems and the Galactic Republic. Ultimately, the Republic forces, commanded by a Jedi and including Altadan Igar, were victorious, seizing control of the fortress from the Separatists. Subsequently, in 4 ABY, not long before the Battle of Endor, Igar recounted the incidents that occurred on Celes IV and the fortress to Jedi Knight Luke Skywalker on Endor's forest moon.
