Xer ' s Campaigns Xer ' s Campaigns were a series of military campaigns launched by Pirate Xer in the Pre - Republic era between 25 , 150 BBY and 25 , 130 BBY . They allowed him to become King of Cron and conquer all the Tion Cluster , excepting the Livien League . Prelude . Around 27 , 000 BBY , Human colonists aboard sleeper ship s from the Core Worlds had settled the Tion Cluster while the galaxy was ruled by the Rakata Infinite Empire . In the aftermath of the Rakatan Civil War , the Infinite Empire was expelled or withdrew from its scattered colonies , leaving much of its technology behind to its former slaves . By 25 , 200 BBY , the year of Xer ' s birth , the Humans of the Tion had formed three states : the Kingdom of Cron , the Kingdom of Barseg , and the Livien League . Xer ' s homeworld , Argai , was nominally part of the Kingdom of Cron , then centered around an arc of worlds from Janilis VII to Algor , but the distant world on the edge of the Ihala Spiral was routinely ignored by the royal court on Chandaar . Like many Argaians , Xer turned to piracy , becoming a prominent pirate chieftain . Hailed the Lord of Argai , he seized Dravione and proclaimed the Kingdom of Argai . Xer moved down the Ihala Route , and within a decade had expanded his kingdom to Panna . In response to the growing power of Argai , King Ferece of Cron summoned Xer to Chandaar , where he offered the pirate - lord noble titles in exchange for an oath of fealty . Offended by the offer and perceiving Ferece and his court to be weak , Xer resolved to conquer the Kingdom of Cron . The Conquests . The Cronese Sweeps . Assembling a fleet at Panna , Xer destroyed a Cronese fleet gathering at Duinarbulon before conquering Chandaar and putting Ferece to flight . Proclaimed Xer VIII , King of Cron , Xer suborned the kingdom and took as hostages the heirs of those nobles and warlords he considered useful , and destroyed the families of those he did not . Xer ' s teenage son Xim gained a feared reputation in the Cronese Sweeps , killing everyone in the Timber Palace of Pasmin , setting the royal barges of Eibon adrift into the heart of the Ihala Spiral , and razing the High Fane of Xo on Nuswatta , converting the theocracy to Xer ’ s service . The Three Allied Kingdoms . The Cronese Sweeps created a united , expansionist Kingdom of Cron and a battle - tested navy . Xer soon prepared to conquer beyond Cron ’ s borders , targeting the Three Allied Kingdoms , an alliance of Cadinth , Jaminere and Barseg on his north - rimward flank . Xer moved along the Cadinth Run and conquered the three kingdoms , as well as worlds such as Arcan IV , Corlax 4 , and Lianna . The Back Spiral . Xer then conquered beyond the Ihala Spiral . Moving from Algor , he moved north up the Spiral , winning victories at Caluula , Brigia and Tion . After the conquest , Xer built gleaming palaces on Raxus Prime and deeded the world to his concubines and their retainers . The world ultimately became known as " the Circlet of the Tion " . The Livien League . The Livien League , a confederation of worlds built around Livien , Desevro and Kanaver , was the only military power in the Tion to successfully defy Xer . Xer ' s attempts to move into the League from Corlax and Barseg were defeated at Amarin , and again at Lorrad . In the aftermath , Xer ended his campaign against the League and paused to consolidate his conquests . Aftermath . Seeing he had overstretched himself , Xer suspended his conquests and spent the remainder of his rule forging Cron into an empire , extending its network of hyperspace beacon s along the Back Spiral and the Cadinth Run and creating an efficient bureaucracy . Xer still harbored ambitions for the League , however . He organized Cron into three provinces ruled from Chandaar , Raxus Prime and Cadinth , but court rituals referred to the Four Thrones of Cron : those three worlds and the still - independent Desevro . The Livien League would later be conquered by Xer ' s son and heir Xim .
