Antar Atrocity The Antar Atrocity was the name given by the media to an operation undertaken by the Galactic Empire in which Imperial forces , led by Wilhuff Tarkin , carried out arrests , executions , and massacres on Antar 4 , as punishment for Antar 4 ' s allegiance to the Confederacy of Independent Systems during the Clone Wars . Origins . The origins of the Antar Atrocity were found in the Separatist Crisis in which thousands of star system s left the Galactic Republic and pledged loyalty to Count Dooku , the leader of the Confederacy of Independent Systems . One world to leave the Republic was Antar 4 , which had been a member of the Republic since its inception . The secession began with a schism among the inhabitants of Antar 4 , in which Separatist - allied terrorist groups began to gain power . Republic loyalists from the Gotal species were able to retain their power until after the Battle of Geonosis , but Antar 4 fell to the Separatists . Millions of Gotal fled to Atzerri , a colony world , and were replaced by species loyal to the Separatists , such as Koorivar , Gossam s , and other species . Some Gotal and Koorivar loyalists formed a resistance group , but Antar 4 remained in the hands of the Separatists . The Atrocity . The end of the Clone Wars saw the death of Count Dooku and the Separatist Council , with the Republic claiming victory over the Separatists . With the war at an end , Supreme Chancellor Sheev Palpatine declared himself Emperor and transformed the Republic into the Galactic Empire , promising a new era of peace , prosperity , and security for all of the galaxy . In the early days of the Empire , Imperial forces targeted former Separatist worlds in order to pacify any remnants of Separatist rebellion . Antar 4 was one of those worlds , and Moff Wilhuff Tarkin was assigned to make an example of the formerly rebellious world . The Empire invaded Antar 4 , and Moff Tarkin made no attempt to sort the Separatists from Imperial loyalists when he carried out mass arrests , executions , and massacres . Aftermath . Although the Commission for the Preservation of the New Order attempted to hide the fact that many loyalists had been killed , the news media learned of what happened and dubbed it the Antar Atrocity . The event attracted controversy and attention from members of the Core Worlds , with many citizens clamoring for answers as to what had transpired . To distance him from the controversial events , the Emperor removed Moff Tarkin , his ally and friend , from Antar 4 and assigned him to pacification operations in the Western Reaches , before ultimately assigning him to the Outer Rim Territories to oversee the construction of the Death Star , the Emperor ' s Deep Space Orbital Battle Station . The creation of the battle station would make invasions like the Antar Atrocity obsolete . The fear of the station alone would bring entire star systems to their knees . One of the most vocal reporters of the Antar Atrocity was Anora Fair , who worked alongside Hask Taff to document the arrests and massacres that were taking place . They were assisted by Berch Teller , a disaffected former Republic intelligence operative who provided them with the information they needed to report on the Atrocity . COMPNOR realized this and targeted them for assassination , but Teller was able to bring himself and the others to safety before the Empire could eliminate them . Legacy . Four years later , Teller led a small cell of resistance fighters against the Empire , a cell that included Fair and Taff . They stole the " Carrion Spike " , Moff Tarkin ' s personal vessel , and used it to cause damage and sow chaos in different corners of the galaxy . The Empire eventually captured Teller ' s compatriots and quietly executed them , while Teller himself escaped and later tracked Tarkin to the Moff ' s homeworld of Eriadu , where Teller attempted to assassinate the now promoted Grand Moff Tarkin but was thwarted by Tarkin and his uncle Jova . Teller was left in the wilderness to survive .
