A Mon Calamari Star Cruiser , " Harbinger " was heavily armed with long - range weapons . It possessed a command bridge , engines , a hyperdrive system , and life support . History . In the year 28 ABY , during the Yuuzhan Vong War , in which the extra - galactic Yuuzhan Vong invaded the galaxy , " Harbinger " served as the flagship of fleet elements used by New Republic – allied General Garm Bel Iblis to guard the planet Tallaan against the invaders . " Harbinger " traveled alongside half of the fleet from Talaan as Bel Iblis answered Jedi Master Luke Skywalker ' s call to aid the New Republic in creating a trap for the Yuuzhan Vong in the Deep Core ' s Treskov system , near the moon Ebaq 9 . Once the Yuuzhan Vong fleet was lured into the system , Skywalker , from " Harbinger " bridge , led the ships from Bel Iblis ' force as well as a group from the Smugglers ' Alliance coalition in engaging the Yuuzhan Vong ' s Battle Group of Yun - Q ' aah in one facet of the Battle of Ebaq . The battle ended in a victory for the New Republic forces , with Yuuzhan Vong Warmaster Tsavong Lah being killed during the fighting . At the end of the battle , New Republic Supreme Commander Sien Sovv made his report from the " Harbinger " . " Harbinger " was later one of the multitude of warships that gathered near the planet Mon Calamari to aid the Galactic Alliance , the New Republic ' s successor state , in defending the ocean world from a massing Yuuzhan Vong armada in 29 ABY . At the edge of the Mon Calamari system , " Harbinger " and the Galactic Alliance forces encountered the enemy armada , which shaped itself like a yammosk , a tentacled creature with telepathic capabilities . After Galactic Alliance starfighters opened up holes in the arms of the armada that were formed by lighter Yuuzhan Vong vessels , " Harbinger " and the Super Star Destroyer " Guardian " pummeled the Yuuzhan Vong capital ships in the heart of the armada with their long - range weaponry through the opened firing lanes . As the fighting progressed , the Yuuzhan Vong armada deployed the shielding effects of its dovin basal s between itself and " Harbinger " , " Guardian " , and the " Viscount " - class Star Defender " Viscount " , sparing the armada from the weapons of the trio of battleships . In an effort to change the focus of the dovin basals , Galactic Alliance bombers infiltrated the armada , which forced the Yuuzhan Vong to defend themselves on a different front . Because of the resulting shift in defenses , " Harbinger " and " Guardian " were able to freely target the poorly defended arms of the armada with their weapons , destroying multiple coralskippers and picket ship s . Not long after , the Yuuzhan Vong armada withdrew from the combat zone . Following the action in the Mon Calamari system , Bel Iblis and " Harbinger " accompanied a battle group that included the " Imperial " - class Star Destroyers " Mon Mothma " and " Elegos A ' Kla " , as well as the MC80B Star Cruiser " Mon Adapyne " , to the Yuuzhan Vong – held world of Corulag to liberate it in a surprise attack . Traveling with the rest of the battle group from the planet Contruum , " Harbinger " decanted from hyperspace close to Corulag after the other three Galactic Alliance warships and rendezvoused with " Elegos A ' Kla " . With the help of the other capital ships , " Harbinger " boxed in the Yuuzhan Vong vessels , and the resulting crossfire destroyed many of the enemy coralskippers . During the fighting , Yuuzhan Vong – allied Peace Brigade TIE fighters launched from Corulag , and General Tycho Celchu , who was commanding " Elegos A ' kla " , was assigned to deal with them , with " Harbinger " to aid Celchu if needed . In the end , Corulag was liberated from the Yuuzhan Vong , with " Harbinger " playing an important role in the fighting . Commanders and crew .
