Tre Sana Tre Sana was a Lethan Twi ' lek male and a resident of the planet Kalimahr in the Tython system during the height of the Infinite Empire ' s reign ; an empire that Sana and the rest of the system ' s residents were ignorant to . A criminal and a rogue , Sana was an outcast whose flesh had been manipulated by Je ' daii Master Dam - Powl ' s alchemy to become an informant . Circa 25 , 793 BBY , Sana came into information revealing the plans of the Stargazer Sect , to which he alerted the Je ' daii and assisted them in finding and eliminating . Biography . Early life . Born within the Twi ' lek community on the planet Kalimahr , the red - skinned Tre Sana was born with an additional lekku sprouting from the back of his head , making him something of a freak among his fellow Twi ' leks . Shunned and harassed for his abnormal number of brain - tails , Sana became a criminal to survive , murdering his first sentient at the age of seventeen outside a bar . Gathering a sizable following over the next few years , Sana and his gang moved their operations to the planet of Shikaakwa where his big time operation became just another gang in the streets of the corrupt planet . There his empire was destroyed by the Nine Houses , but his life was spared because of a perceived usefulness in his spying abilities . Two of the houses hired him as a messenger in exchange for his life , ordering him to take messages which could not be written down or transmitted and deliver them in person . During this time he encountered the Cathar Je ' daii Master Dam - Powl who performed an arcane form of alchemy on Sana ' s brain to make his mind impenetrable , even by a Je ' daii , in order to keep him alive . In exchange for the alteration to his brain , Sana was promised fortunes and a new identity if he served as an occasional informant for the Je ' daii Order . Stargazer Uprising . Contacting Master Dam - Powl in 25 , 793 BBY in regards to whispers of a group calling themselves the Stargazer Sect and their desires to leave the Tythan system , Sana met with Je ' daii Ranger Lanoree Brock on Kalimahr and promised to assist her in the hunt for the leader of the group , her brother Dalien Brock . Taking her to see the corpulent socialite Kara in the city of Rhol Yan , Sana helped the Je ' daii escape the apartment after stunning the obese woman and leaping out of her skyscraper to land on Brock ' s " Peacemaker " cruiser and heading for the planet Nox . While keeping himself closed off to her , Sana and Brock developed a mild camaraderie as the two braved the perils of Greenwood Station together in their search for the crime boss Maxhagan and the hidden labs of Pan Deep . When they gained entrance to the hidden labs underneath the city , Sana was injured when the pair were captured by Stargazers and brought before Dalien Brock . Leaving the pair for dead after completing the Gree technology being constructed there , Sana and Brock escaped to the surface to find the domed - city of Greenwood Station being destroyed by attacking forces from rival stations . Fleeing across the toxic wastes outside the city , Sana became dangerously ill after breathing the atmosphere and was confined to the " Peacemaker " during their journey to the planet Sunspot . Resting aboard the ship on Sunspot when Brock went out in search of her brother , Sana realized something was wrong when the Stargazer ship departed and Brock did not return from the mines she was searching . Taking the droid Ironholgs with him , they discovered Brock severely injured in the mines with a blaster hole in her chest from where her brother had shot her . Carrying her back to the ship , Brock was able to use her knowledge of Force alchemy using Alchemy of flesh to meld one of her experiments , a living piece of her own flesh , into the blaster wound and heal herself . Still recovering from exposure on Nox , Sana accompanied Brock to Tython as she attempted to catch up to her brother and the Stargazers . Chasing him into the Old City , the pair went in without any backup from the Je ' daii , as a series of violent Force storms were plaguing the world . Avoiding traps set by the Je ' daii at every turn , the pair was eventually ambushed by a Stargazer who fired a series of blaster shots at Brock . Screaming for her to get out of the way , Sana pushed Brock aside and took a blaster bolt to the neck , putting him into a coma . Brock left Sana in the tunnel for several hours as she hunted her brother , and after finding him and slaying him , returned to tend to Sana ' s wounds . Transporting him to the Temple of Science , Anil Kesh , Sana was tended to by healers with far superior skills to Brock ' s own .
