Duel in the Lake Brell colony bunker In 3643 BBY , during the Sith Lord Darth Angral ' s campaign of vengeance against the Galactic Republic for the death of his son , Tarnis , a duel occurred in a Republic colony on the planet Taris between the Sith assassin Rora Seake and a young Jedi Knight . Seake had been sent to wipe out the Republic colony , but the Jedi Knight learned of Seake ' s mission from the Imperial operative Watcher One as part of a bargain the agent made with the Jedi . The Knight was too late to evacuate the colony before Seake ' s arrival , but the Jedi and a companion were able to kill the assassin and the two jurgoran pets she used as war beasts , saving the colonists from execution . Prelude . In 3643 BBY , during the Cold War between the Galactic Republic and the Sith Empire , the Sith Lord Darth Angral declared war on the Republic for the death of his son , Tarnis , and stole a number of Republic superweapons in his pursuit of revenge . Angral also tasked Watcher One of Imperial Intelligence with the capture of the Republic scientist Doctor Nasan Godera on the planet Taris . Republic General Var Suthra sent a young Jedi Knight , the same Jedi who had killed Tarnis , to locate Godera and bring him back to the Republic ' s capital of Coruscant . Watcher One remained one step ahead of the Jedi Knight and managed to ferry the unconscious scientist to the Imperial Intelligence Outpost on the planet , and , in order to secure time for him to interrogate Godera , he contacted the Jedi to make an offer . Around the same time , a Sith assassin named Rora Seake was tasked with sabotaging the Republic ' s efforts to recolonize Taris , and her first target was a colony on the shores of the acidic Lake Brell . In exchange for time to interrogate Godera , Watcher One revealed the existence of Rora Seake and her mission , and he promised to permit the Knight to come to the Imperial outpost and retrieve the scientist when their business was concluded . Unwilling to put the mission ahead of the lives of the colonists , the Jedi agreed to Watcher One ' s bargain . The duel . The Knight and a companion rushed to the colony bunker , where the duo found the colonists hard at work establishing their settlement under the leadership of a Human named Yelzrin . Yelzrin welcomed the Jedi and offered foodstuffs and water , but the Jedi attempted to warn Yelzrin of the forthcoming threat so that the colonists would evacuate . Despite his confusion , Yelzrin started to round up the colonists , but Rora Seake arrived at the bunker with her two pet jurgoran s only moments after the Jedi . Seake was surprised to see a Jedi , and she questioned the Knight as to how her mission had been compromised . Irritated that Watcher One had exposed her mission , Seake ordered her jurgoran pets to attack the Knight and the Jedi ' s companion , and she withdrew to meditate and control her pets in battle . However , the duo ultimately fought and killed the two creatures , knocking Seake out of her meditation and prompting the assassin to draw her orange - bladed lightsaber , and she then attacked the Jedi herself . The Sith wielded both blade and lightning in their duel , but the fight ended when Seake was struck down . Aftermath . A relieved Yelzrin offered the Jedi some of the colony ' s limited supplies as a reward , but the Knight declined the offer and departed with the Jedi ' s companion to continue their mission . The duo followed Watcher One ' s coordinates to pick up Godera , but Darth Angral , who was furious to learn that the agent had compromised with the Jedi who had killed his son , ordered Watcher One to capture the Knight . Godera was ultimately rescued by the Knight , who delivered the scientist to the custody of the Republic Strategic Information Service , the Republic ' s intelligence agency . Behind the scenes . The duel with Rora Seake first appeared in the Jedi Knight - class mission " A More Immediate Concern " in " " , a video game released by BioWare in 2011 . Players only receive this mission if they have a light - side alignment , while players with a dark - side alignment receive " An Opportunity Too Good to Pass Up , " in which they stop a Sith from acquiring Jedi artifacts . Players can also choose to bypass the mission entirely , though as the Knight is a Republic - class character and therefore assumed to choose the options that give the most light - side alignment points , this article assumes that the Knight defended the colony . According to the game ' s text files , players originally were able to Force Persuade Seake into leaving , but that option was removed .
