Berch Teller Berch Teller was a captain in Republic Intelligence during the Clone Wars , and later led an insurgent cell that fought against the Galactic Empire . Biography . During the Clone Wars , Teller served the Galactic Republic as a Republic Intelligence station chief with the rank of captain . He was one of the officer s that debriefed Captain Wilhuff Tarkin after his escape from the Citadel with the coordinates to the Nexus Route . Under the oversight of Dodd Rancit and in association with Knotts , a subcontractor from Lantillies , he worked with loyalist beings on worlds that had joined or were occupied by the Confederacy of Independent Systems , training them to serve as resistance fighters for the Republic . In the war ' s final year , he was assigned to the Gotal moon of Antar 4 , organizing the Gotal and Koorivar partisans into well - armed resistance groups . At the end of the war , he expected the Galactic Empire to spare them from punishment due to their work for the Republic during the conflict , and appealed to his superiors in the Imperial Intelligence community to provide documentation and transport for their extraction . However , COMPNOR refused to cooperate , allowing forces under the command of now - Moff Tarkin to kill many of the fighters on Antar 4 along with former Separatists , which became known as the Antar Atrocity . This event angered Teller and shortly after being assigned to Desolation Station , which focused on research for the top - secret Death Star project , he deserted the Empire . With this disappearance , he created his own resistance cell to fight against it , while intending to inspire the creation of other rebel groups throughout the galaxy . Their most notable action happened five years after the end of the Clone Wars . When Tarkin and Darth Vader visited Murkhana on an investigative mission , Teller and a few of his accomplices , including Anora Fair , hijacked Tarkin ' s vessel , the " Carrion Spike " . They killed the ship ' s captain and comms officer , along with two stormtrooper s , before taking off . The Imperials forced Faazah , a local Sugi crime lord , to give up his ship to them , and attempted to stop the captured " Spike " . However , Teller and his crew got away . After the successful hijacking , the insurgents of the " Carrion Spike " went on a campaign of destruction against various Imperial targets , such as Galidraan Station . Their information was supplied to them by Vice Admiral Dodd Rancit , a member of the Imperial Naval Intelligence Agency . However , Rancit was revealed as a traitor and executed on Vader ' s orders . The insurgents , led by Teller , carried out an attack on an Imperial convoy transporting important parts for the Death Star project . They were unsuccessful due to the arrival of Tarkin aboard a Star Destroyer . Teller escaped in a fighter when his attack failed , at the urging of his comrades . His insurgents who helped capture the " Carrion Spike " , and others , were captured and executed . Teller later tracked down Tarkin on his homeworld of Eriadu , where he followed him into the wilderness and was caught in a trap . He broke his ankle , and briefly conversed with Tarkin and his relative , Jova . After they finished , Tarkin and Jova left him in the wilderness to see if he could get out of it alive after nightfall . Legacy . Some time after Teller ' s campaign , the Rebel Alliance saw Teller as a prime example of how counter - propaganda would be useful , and that if it weren ' t for him , the galaxy would not be aware of the Antar Atrocity .
