Jekk ' Jekk Tarr The Jekk ' Jekk Tarr was a cantina that was located within the spaceport docks of Nar Shaddaa and circulated cyanogen fumes along with a variety of other pollutants that were lethal to Humans and Nikto , but commonplace for , and often preferred by , many other alien species . Before its establishment as a cantina , it was a ventilation system for passing nagnol gas es to the docks . It was designed to be a haven for the more exotic species of the galaxy ; its very atmosphere providing a buffer against less desirable company . Instead of serving drinks , the bar served " nutrient chemicals " to its clientèle , who paid large sums of credits for the privilege . Layout . The Jekk ' Jekk Tarr was divided into five sections , each lit with a different light that represented the environment it simulated . Upon entering , a customer would arrive at the infrared chamber , which was lit with a red light . This area was favored by species that could perceive the infrared , such as the Devaronians and Trandoshans . Adjacent to the west of this chamber was the yellow , arid room , designed to simulate the harsh climate of worlds such as Ryloth and Sriluur . Because of this , this chamber was frequently inhabited by Twi ' leks and Weequays alike . To the east of the infrared chamber was a green room of particularly toxic gases . A second toxin room lay to the north of this , and both areas were almost entirely used by the insectoid Gand only . It was likely that the gas in these two rooms was ammonia from their home planet Gand . The fifth chamber was non - toxic and contained no harmful fumes even to Humans . It was a private lounge used by the Quarren Exchange crime lord Visquis , and thus it was locked to anybody but Visquis and his servants . In his lounge was the entrance to his secret headquarters , which contained a dimly - lit maze with lethal gases and a jamming system to insure that datapad maps were rendered useless . History . The Exchange crime lord Visquis would often use the bar for dealings he wanted kept secret from Goto , having discovered accidentally at some point that Goto could not monitor events that happened inside the Jekk ' Jekk Tarr . This was because droids did not function properly inside of it . During her time on the moon in 3951 BBY , the Jedi Exile was lured here by Visquis in his attempt to claim the Exchange ' s outstanding bounty on Jedi . She survived the hostile environment using the Force , harnessing the power of breath control in order to conserve oxygen and to prevent the gases from being inhaled . When Visquis saw that the gas had no effect on her , he commanded the bounty hunters and other bar patrons within to attack her , offering a huge reward to whoever took her down . She was attacked by a Devaronian bartender and a Twi ' lek majordomo , among others , before eventually reaching Visquis ' s private room . During the battle , she convinced the " Lunar Shadow " captain to go back to his crew before continuing her pursuit through the tunnels below the cantina and into Visquis ' s lair . Upon returning at a later time , the Exile found that the Jekk ' Jekk Tarr had been closed . Behind the scenes . The Jekk ' Jekk Tarr first appears in the video game " " . The cantina and the base below it were originally intended to have been one of the lairs of the secretive bounty hunter guild known as the GenoHaradan . However , this was cut from the final game and the base became the stronghold of Visquis ' faction of the Exchange . The player can enter the Jekk ' Jekk Tarr without a spacesuit before the quest to rescue Mira activates without any consequences to the Exile ' s health , provided that she is equipped with a gas mask ; if this is done , she can contact the " Lunar Shadow " captain before the bar patrons become hostile . The Exile can also recruit Odis to be the new captain for the " Lunar Shadow " crew before entering the cantina . Nevertheless , the former captain cannot be killed , and is the only patron to remain neutral during the skirmish . " Knights of the Old Republic II : The Sith Lords " , the only source thus far in which the Jekk ' Jekk Tarr appears , misspells the cantina ' s name once as " Jek ' Jek Tarr " , within the Music list accessible from the game ' s menu screen .
