A Kashi Mer Dynasty exile , he spoke out against the teachings of the Jedi and was forced into open war by the Jedi Order . With his lover Arden Lyn at his side , he fought in the war of the First Great Schism and was eventually killed on the day of the Legions ' defeat at Columus . Lyn survived , but was placed in a deep trance following a confrontation with Jedi Master Awdrysta Pina . As the New Sith Wars raged , rumors abounded of Xendor ' s return in the form of the enigmatic Dark Underlord . By the time of the Imperial Period , Xendor took on new life as a popular curse uttered by smugglers . During this time , Lyn was awoken from her preserving trance , and she made several attempts to resurrect Xendor . She was eventually slain by Emperor Palpatine , a Sith Lord . Biography . The First Great Schism . A Force - sensitive Human of the Kashi Mer Dynasty , Xendor was exiled after he began to embrace and follow Bogan , the darker aspects of the Force , in conjunction with the use of the Teräs Käsi martial art . Upon departing home , Xendor took with him a talisman marked with the sigil of his house . Taking refuge with the Jedi Order on their fortress world of Ossus , Xendor became a well respected Jedi Knight . During his time on Ossus , Xendor became increasingly outspoken of the Order ' s progressively close - minded attitude towards other Force - traditions and the study of Bogan . During this time , Xendor met a Steel Hand of Palawa named Arden Lyn and began to learn about the philosophies of Palawa , eventually taking her as a lover . Xendor , able to bear his frustration no longer , approached the High Council and requested their blessings in opening a new Jedi academy far from Ossus to focus on the darker aspects of the Force , the Bogan . When the Council refused , Xendor quietly broke with the Order and traveled to the planet Lettow to open an academy which focused its teachings on the Bogan . Drawing on Force traditions such as the Dai Bendu , the Followers of Palawa , the Kashi Mer Guardians of Breath , the Baran Do , and the Chatos Academy , Xendor ' s academy drew a trickle of interest which quickly transformed into a roaring river . It was these acolytes which named their new group the Legions of Lettow , as they knew that they would one day be forced to defend their traditions from the Jedi High Council ' s wrath . Sometime during Xendor ' s life , he traveled to a dead planet where the Force was worshiped as a trio of beings . He would later recount the tale to Arden Lyn , telling her of the Daughter , the embodiment of the light side , and the Son , the embodiment of the dark side . When Lyn asked about the Father , he cryptically replied that he might have been the Force itself . When asked what he had discovered , Xendor simply laughed and told her that there were many truths to the Force — the existence of the triad had no bearing on the truth of the Force more than the views of the Legions or the Jedi . Taking the rank of general sometime in the 24 , 500s BBY , Xendor was forced to lead the Legions of Lettow in open warfare against the Jedi Order when the High Council declared war with him . Known to history as the First Great Schism , Xendor hoped to avoid massive bloodshed by bringing the war directly to Ossus . During the battle , Xendor ' s forces were pushed back and forced to commit troops to several fronts as the Order pushed the Legionnaires towards the galaxy ' s core . In an attempt to warn the Galactic Republic of the Jedi Order ' s machinations in forcing the conflict into civilized space , Xendor was ignored and branded as a warlord by the Republic . Campaigns were played out on Chandrila , Metellos , Brentaal IV and Coruscant until the Jedi leader , Awdrysta Pina managed to come into direct battle with Xendor on Columus . Known as the Green Blade , Master Pina and his Jedi Knights were able to separate Xendor ' s vanguard from the bulk of his army through the use of a strong Force meld . Cutting through powerful warriors such as Sethul Asaiage and Tun Bohoi , Pina eventually dueled Xendor and slew him in hand - to - hand combat , and his spirit plunged into Chaos . News of this was transmitted to even Jedi Padawans on far - flung worlds , signifying what was thought by some to be the immediate end to the war . Legacy . On the day that Xendor died , the Legions lost the Battle of Columus , with the sole survivor being Jedi Padawan Danzigorro Potts . Before dying of his own mortal wounds sustained in the battle , Potts made a recording on a datacard that would become and remain famous for thousands of years after the First Great Schism . In it , the Padawan speculated on just how and why Xendor had been able to sway so many to his cause . In the wake of Columus and Xendor ' s death , Arden Lyn led the defeated Legions of Lettow . In the aftermath of the schism , she was hunted down by Jedi Master Awdrysta Pina , forcing Lyn to destroy her assailant with Xendor ' s Kashi Mer talisman . Prior to perishing , Pina used the technique of " morichro " to stop Lyn ' s heart , and as a result , the Follower of Palawa fell into a deep and long trance that preserved her . The First Great Schism would prove to be the first of several conflicts between the light and dark sides of the Force . Over the centuries , various wars stemming from the dispute between the two schools of thought would be waged , at a tremendous loss of life . During the New Sith Wars instigated by Darth Ruin in 2000 BBY , an enigmatic figure known only as the Dark Underlord rose to power . Speculation abounded as to his origins , with one theory suggesting that he was in fact the returned spirit of Xendor . The Dark Underlord was eventually destroyed by the Jedi Master Murrtaggh . Around two dozen millennia after the First Great Schism , Arden Lyn was woken by Imperial Inquisitors — Dark Jedi in the service of the Sith Lord Palpatine . Instead of being annihilated , Lyn was converted to Palpatine ' s cause and served him as one of the Emperor ' s Hand s . In turn , he promised her that he would summon Xendor ' s spirit back from Chaos . Lyn soon realized that Palpatine did not intend to make good on his promise and participated in an attempted coup against him led by Grand Admiral Demetrius Zaarin in 3 ABY . When that failed , she scoured the galaxy for the Kashi Mer talisman that she had possessed in her earlier life , hoping to regain the influence she had enjoyed during the Schism . She also intended to resurrect Xendor herself with the power of the talisman . Lyn was later personally slain by Palpatine . During Palpatine ' s reign , Xendor ' s name would be frequently taken in vain by smugglers such as Han Solo and Lando Calrissian . The phrase " Minions of Xendor " became a popular curse during this time , particularly with Solo . In 36 ABY , Xendor found his way into the writings of New Republic historian Voren Na ' al , and four years later , into the writings of Jedi historian Tionne Solusar . The contents of Danzigorro Potts ' data card , known popularly as the Columus Data Card , were collected in Solusar ' s writings . The card had been the inspiration for at least three operas on Coruscant , but had been decried by historian Ingo Wavlud as mere Jedi propaganda . Even by this stage , Xendor ' s origins remained a mystery , at least to the New Jedi Order . Personality and traits . A courageous and powerful Human man , Xendor posed the first true threat to the Jedi Order . By highlighting and emphasizing the routine and , in the view of his followers , stifling nature of the Jedi way , he was able to sway legions of Jedi to his cause — even experienced Jedi Masters . He simply told the Jedi that he did not have to follow orders , and in doing so secured his place in galactic history . Xendor had fair skin and dark hair . Behind the scenes . Xendor was first mentioned in A . C . Crispin ' s " The Paradise Snare " , where the name was used repeatedly in various curses uttered by characters . The name was mentioned in much the same capacity in the two other books in that series , " The Hutt Gambit " and " Rebel Dawn " . The character of Xendor was greatly embellished upon by Abel G . Peña in his article " The Emperor ' s Pawns " , which was published in " Star Wars Gamer 5 " . Further , fleeting mentions were made by Daniel Wallace in " The New Essential Chronology " , as well as by Drew Karpyshyn in the article " Heritage of the Sith " , published in " Star Wars Insider 88 " . Peña once again used the character briefly in " " , and Ryder Windham would , in 2007 , expand upon the character once more in " " . The 2012 reference book " " provided a picture of Xendor .
