T ' surr ( species ) The T ' surr were a sentient species indigenous to the planet of T ' surr . T ' surr were rarely seen in the galaxy . The species was among the galaxy ' s most dangerous predators , although their relative scarcity made them less threatening . Indeed , one of the most famous T ' surr was the notorious pirate and slave trader , Krayn . Although their level of technology did not meet the galactic standard , T ' surr capably used technology scavenged from the ships of their victims . Biology and appearance . The T ' surr were a sentient humanoid species of blue skinned and blue blooded predators . Their appearance followed that of most humanoids , with members of the species possessing a bipedal stance with two legs and four arms . Two of their arms ended in meaty hands with either five or three fingers , while the second pair was far smaller than the first and protruded from their upper torso ending in only three fingers . The species displayed sexual dimorphism between its two sexes , with males on average standing between 2 . 3 and 2 . 6 meters tall , while females stood at only around 2 meters . Males were also physically stronger than females , being solidly built , with some males being able to spin a vibro - ax in one hand like a toy . A T ' surr ' s head included a mouth full of razor sharp teeth , a nose , and two sets of gleaming red pupiless eyes , with one set situated above the other or all four eyes in a horizontal line above the nose . Around the eyes and mouth a T ' surr ' s face was heavily ridged , with the creases slanting out toward the fan like sides of the head , which extended into a large number of horns in males . T ' surr were capable of growing hair on their heads , including beards , which could be black in color . A T ' surr ' s face was capable of producing expressions of nervousness , amusement , sadness and astonishment amongst others , and when a T ' surr was enraged its neck would flush red . Society and culture . T ' surr originated from the desert planet of the same name in the T ' surr system of the Nuon e Safyd sector , a sector in the Expansion Region of the galaxy . Their homeworld was cold and dark due to its distant star and constantly windblown , with other species finding the high gravity there daunting and oppressive . These conditions created a race of survivors who had little empathy for other beings , making practices like slavery common and accepted amongst the T ' surr . Within T ' surr society wealth was judged based upon how many slaves an individual owned as well as their quality , with a T ' surr with no slaves was seen as worthless and was looked down upon by others . Male T ' surr were violent and cruel in nature , looking down upon weaker species and treating them as livestock to be controlled . A T ' surr would use his strength and cunning to control other males of his own species as well as any member of other species , bullying them to get his way . This was not the case when it came to male treatment of T ' surr females however , as the female T ' surr controlled the species homeworld . Males would anxiously leave the female dominated T ' surr , also allowing mothers to raise any children . Upon leaving their home , T ' surr were often drawn to violent , predatory , professions , joining forces with powerful bands of pirates , privateers , or smugglers . They liked to keep trophies as reminders of their conquests , often wearing these stolen trinkets on their belts . Their species spoke a language called T ' surrese . T ' surr names included Datynask , Dyrago , Feyrr , Jeneyd , Reythan , Shyntak and Treykon . History . Though they were long present in the galaxy , the T ' surr were never represented in any galactic government . The Galactic Republic never allowed them representation in the Galactic Senate because they were widely regarded as nothing more than dangerous , marauding killers . However , some governments , like Sith Lord Daiman ' s Daimanate , happily used members of the species as Sith Trooper s . They were also preferred guards used by the slave traders on Orvax IV . During the last years of the Republic , a notorious T ' surr named Krayn worked as a pirate and slaver . His organization was infiltrated by a Jedi Knight named Siri Tachi , and during her undercover operation , Obi - Wan Kenobi and his Padawan , Anakin Skywalker , also fell into Krayn ' s custody . Though he was a successful criminal and a powerful fighter , Krayn was no match for Skywalker , who had once been a slave himself , and gave in to his anger when faced with Krayn ' s brutality . The young Jedi attacked and killed Krayn with his lightsaber . The New Republic continued the policy of excluding the T ' surr from galactic politics . T ' surr in the galaxy . Amongst the most infamous of the T ' surr was Krayn , a pirate and slaver who operated during the final decades of the Republic . In the year 44 BBY he raided the city of Mos Eisley , capturing a number of slaves from the desert spaceport . Sixteen years later , Krayn was still active and had come to control much of the planet Nar Shaddaa , partly through its ruler Aga Culpa . Due to this power , he was able to make a deal with members of the Colicoid species who hoped to take over the galactic spice trade . Krayn would be the sole provider of slaves for the Colicoids and in return he agreed to stop attacking Colicoid ships , although in secret he arranged for an attack on a Colicoid cargo ship being piloted by the Colicoid Anf Dec . Krayn was present for the attack , but it was foiled by two Jedi , Obi - Wan Kenobi and his Padawan Anakin Skywalker , who boarded Karyn ' s ship and disabled its weapons systems , forcing the pirate to retreat . Krayn and his crew then traveled to Nar Shaddaa to meet with the Coliocoids to discuss their arrangement . While there he submitted to a review of his operations by an agent selected by the Colicoids , named " Bakleeda , " and discovered that one of his crew , " Zora , " was in fact a Jedi , whose real name was Siri Tachi . Tachi , who , in truth , was working undercover for the Jedi High Council , was imprisoned as a result for her treachery , but the Jedi agent managed to escape with the help of Skywalker and Kenobi , who ' d assumed the identities of a slave and " Bakleeda , " respectively , and who ' d turned Krayn ' s allies against him . After Culpa and the Colicoids abandoned Krayn , and his slaves had revolted against him , Skywalker sought the slaver out and killed him by impaling him with his lightsaber . Behind the scenes . The T ' surr species first appeared in " " , a novel written by Jude Watson in the " Jedi Quest " series and the series of comic books based on the book and released at the same time . The comics , which were written by Ryder Windham and illustrated by Pop Mhan , had a number of significant differences in terms of the appearance of the T ' surr character Krayn , whose species wasn ' t named in the book or comic . In the comics there is a notable difference between Krayn ' s appearance in the first issue compared to those that follow . In the first issue he lacks a nose and has a number of spines running down the back of his neck , however in the three later issues he has a clear nose and no spines . This article assumes the three later articles are correct as they match later illustrations of T ' surr more closely . The species next appeared in 2003 as part of a series of previews for the soon - to - be - released sourcebook " Ultimate Alien Anthology " for the Wizards of the Coast " Star Wars Roleplaying Game " . The article was the first to identify Krayn ' s species as being T ' surr and provided roleplaying rules for the species . It was written by XXX with an illustration by Kalman Andrasofszky . The sourcebook contained all of the same content concerning the T ' surr and was released later that same year . In 2006 a T ' surr appeared in " " , a comic strip written Paul Ens and illustrated by Thomas Hodges , which was released on the section of the StarWars . com website . The comic series " " also included a number of T ' surr characters in the " " arc released in 2006 and the " " arc released in 2009 .
