Garos IV Garos IV was a planet in the Mid Rim , the fourth world in the Garos system . Located near the Nyarikan Nebula , it was somewhat isolated from outside contact and its inhabitants were a tough , self - reliant people . It was the homeworld of Imperial officers Brenn and Dellis Tantor , and the adopted homeworld of New Republic Captain Alexandra Winger . In the Post - Imperial period , the planet was best known for the University of Garos , whose database of secret Imperial files were available for academic study . Description . Orbited by two moons , Garos IV was a pleasant world of forests , mountains and oceans . Its population was concentrated on a single continent in three major centers : the waterfront resort town Zila , located on the shores of the Locura Ocean ; the manufacturing seat and agricultural breadbasket Garan , situated on the Salc River , near the Morcur Valley ; and the capital city Ariana . . South of the capital lay the Tahika Cliffs , an impressive mountain range from which the Locura Ocean could be seen . The Old Currahen Highway connected Ariana and Garan . An Imperial mining center complex was established at Mount Usca , which lay on a cape where the Locura Ocean and Cabalia Sea met and could be accessed via the Currahen Crossroad . The planet ' s spaceport lay on the outskirts of Ariana . Garos IV was largely self - sufficient , so fluctuations in the economy of the New Republic did not have much impact on it . History . In 25 , 000 BBY , a Ssi - ruu k vessel with an experimental hyperdrive crashed on the planet . In approximately 4000 BBY , Garos IV was colonized by Humans . At an unknown date , colonists from the neighboring planet of Sundari began migrating en masse to Garos IV . Tensions grew between the Garosians and the Sundari until war later erupted between the two worlds . The conflict raged for generations , with at least one intermission . By 87 BBY , the conflict had recommenced . Sometime between 46 BBY and 44 BBY , the Garosians first began to enter the service of the Galactic Republic . Garos IV allowed Refugee Relief Movement settlement in 22 BBY , shortly before the First Battle of Geonosis . Garos IV was the site of a victory for the Confederacy of Independent Systems over the Republic during the early stages of the Clone Wars . The planet was in Separatist space until an unknown point before the Outer Rim Sieges . Sometime before 12 BBY , Garosian politician Tork Winger and Sundari engineer Tionthes Turi negotiated a truce between the warring factions of the Garosian Civil War . Even as peace negotiations began , violations of the truce took place , including the Whahalla Massacre and the assassination of peace advocate West Haslip and his wife . By 6 BBY , the Galactic Empire began to take a greater interest in the Garos system . The Empire quickly put an end to the conflict , executing hundreds of activists on both sides . Once peace had been enforced , Winger was appointed as the Imperial governor of the planet . Most of the Imperial forces later left Garos IV , with the chief Imperial presence maintained at a garrison and a mining center complex on the western shoreline of the main continent dedicated to mining hibridium . The hibridium mined from Garos IV was used in the development of new cloaking devices . In 4 ABY , the site of the failed Ssi - ruuvi Hyperdrive system was found . After the planet ' s subjugation , an insurgency , the Committee of Seven for Garosian Unification , had emerged on Garos IV . The Battle of Endor caused the Garosian resistance to believe they would soon be rid of the Empire , but the Imperial forces instead stepped up their efforts to quarry the planet ' s hibridium . Taking advantage of support from Alexandra Winger , the adopted daughter of the Imperial Governor , the resistance undertook a number of actions against the Imperial garrison , including ambushes on hibridium convoys and attacks aimed at the Imperial mining facility . During a rescue operation to Sarahwiee following the Thrawn campaign , Alexandra Winger met Luke Skywalker , who alerted the New Republic to the planet ' s situation . The New Republic subsequently sent a fleet to liberate Garos IV . Aware of the impending invasion , the Empire sent Dark Jedi Jaalib Brandl to evacuate Imperial dignitaries . In the subsequent battle , the Garosian resistance supported the New Republic . The planet itself suffered little damage in the brief conflict . Garos IV joined the New Republic after the battle . The Imperial forces that evacuated the world failed to destroy numerous classified documents . These files were maintained by the University of Garos . Scholars used the secret Imperial files to complete studies on the Empire . The influx of scholars increased the school ' s reputation and prompted the university to expand . An economic boom followed , while Garos IV appeared on numerous lists of desirable planets to live on . Sometime between 26 ABY and 27 ABY , the Yuuzhan Vong conquered the world during their invasion of the galaxy . By 137 ABY , Garos IV was within space controlled by Darth Krayt ' s Galactic Empire .
