- "You were a great Jedi, Hett, and the son of a great Jedi. But you have given yourself over to revenge. It stops here."
- ―Obi-Wan Kenobi, speaking to A'Sharad Hett[src]
The Duel on Tatooine was a skirmish that occurred in the year 17 BBY. Having survived Order 66, A'Sharad Hett returned to his homeworld of Tatooine and became warlord of a number of Tusken Raider clans, as his father had done decades before. Leading the Tuskens in an aggressive campaign against the settlers of Tatooine, Hett and his war band eventually came across the Lars homestead on the outskirts of the Jundland Wastes. Little did he know, however, that the Lars moisture farm was under the covert protection of Jedi Master Obi-Wan Kenobi, another survivor of Palpatine's Order 66. After a brief discussion between the two Jedi, during which Hett refused to put an end to his campaign of aggression, Kenobi and Hett found themselves involved in a fierce duel. Despite Hett's skill with wielding two lightsabers, Kenobi was able to defeat the fallen Jedi. Kenobi then made Hett swear on his father's honor not to return to Tatooine again, thus ensuring the continued protection of the Lars Homestead. Hett complied with Kenobi's demands, and agreed to never return to the backwater desert world. �
- "I reached out through the Force, but could not sense any other Jedi. A light had gone out in the galaxy and I was alone. The 'Jedi Purge', as it was became known, was extraordinarily effective."
- ―Darth Krayt, retelling his survival of Order 66[src]
In the final moments of the Clone Wars, Palpatine issued a top-secret command, better known as Order 66, to a number of clone commanders. The order commanded the clones to assassinate their Jedi commanders, and the Jedi Order was virtually annihilated as a result—the Great Jedi Purge had begun. � A'Sharad Hett, killing the Clone troopers assigned to execute him during Order 66.Meanwhile, A'Sharad Hett, a Tusken Jedi, had been on a scouting mission near enemy lines, away from his clone troopers, when the order was given. After witnessing the deaths of numerous Jedi comrades, Hett made his way back to his clones and killed those assigned to execute him. After killing most of the clones, he kept one trooper alive just long enough to learn what had transpired, and why the clones had turned on the Jedi. Following his survival of Order 66, Hett fled the field of battle and attempted to reach out to other Jedi through the Force. However, he was unable to sense any other Jedi and, fearing the worst, set out to plan his own private war against the forces of Palpatine.
Believing himself to be the only Jedi to have survived Order 66, Hett made his way back to his birth world of Tatooine, and once again donned the wrappings of a Tusken Raider. Just as his father had done before him, A'Sharad Hett united several Tusken clans and proclaimed himself their warlord. In response to the age-old war against the Tusken people by the settlers of Tatooine, Hett led his new war bands in retaliation against the Human settlements that had encroached on Tusken land. Honed through years of fighting in the Clone Wars, Hett's leadership and skills as a warrior did much to gain back Tusken land that had been lost since the death of his father. Under the leadership of A'Sharad Hett, the Tusken Raiders again became a feared fighting unit, taking by force the land that they believed was theirs by right.
Through fragmented reports from other colonists, Obi-Wan Kenobi, who had settled on Tatooine to protect the infant son of Darth Vader, learned that the Tuskens had attacked at least three large moisture farms and had even killed seven farmers in a single day. Unaware that his former comrade had come back to his homeworld following Order 66, Kenobi was unsettled by the strong Force presence that he sensed on the desert world; thinking it might be the Sith, Kenobi determined to stay close to the Lars moisture farm, where young Luke Skywalker was living, in case his help was needed. Setting out to travel to the Lars homestead, Kenobi came across the Valley of the Spirits where he was approached by the spirit of his dead master, Qui-Gon Jinn. His spirit told Kenobi about the slaughter that Anakin Skywalker had precipitated in the valley, and how he had only shared the information with the Tusken-turned-Jedi A'Sharad Hett. Slowly putting the pieces together, Kenobi asked Jinn if the tribe that Anakin had destroyed was that of Hett and his father; however, Jinn would not answer if Kenobi's assumptions were true or not. With this knowledge, Kenobi continued on his route to the Lars homestead, intent on being between Hett and his Tusken army and the Lars family.
- "These are my people! Will the settlers stop killing Tuskens? Then blood calls for blood! The settlers will be forced to abandon the land—or be buried beneath it!"
- ―A'Sharad Hett, speaking to Obi-Wan Kenobi[src]
Eventually Hett and his Tusken warriors came across a small moisture farm on the edge of the Jundland Wastes, which belonged to the Lars family. To Hett's mild surprise, his war band was halted by none other than his old Jedi acquaintance, Obi-Wan Kenobi, who had also chosen Tatooine to hide from Palpatine. � Hett and Kenobi fighting in the Jundland Wastes.While living in the desert, Kenobi had noticed the Tuskens and their aggressive campaign that Hett had been leading, and had decided that he was slowly falling to the dark side. Confronting Hett at the Lars homestead, Kenobi shared with the Tusken warlord his fears that Hett was becoming the very thing that the Jedi had sworn to fight against. Kenobi continued by asking him to stop his crusade against the settlers of Tatooine, but Hett refused to listen to Kenobi. Hett argued that it was the Jedi's job, indeed his job, to defend those who were oppressed, and that that was why he fought for the Tuskens. Refusing to forgive the settlers, whom he had witnessed killing countless Tuskens, Hett advised Kenobi that he would continue his war.
With the whole of the Tusken army watching, the two Jedi ignited their lightsabers and fought a vicious duel in the sands surrounding the Lars moisture farm. The fight lasted for several minutes, and both men demonstrated the skills they had earned throughout their careers as Jedi. The duel, however, ended when Kenobi sliced off Hett's right arm, and tore off his Tusken wrappings—in the culture of the Tuskens, to expose any part of the flesh was forbidden and seen as a disgrace. Also, with only the use of one hand, Hett could not hope to wield the gaderffii, the traditional weapon of the Tuskens, and therefore could no longer be their warlord. Having witnessed their leader defeated and defaced at the hands of a stranger, the Tusken army left Hett to fend for himself in the desert.
Now an outcast unable to return to his home, Hett asked Kenobi to kill him, thus giving him an honorable death in the traditions of the Tuskens. Even though Hett would not have hesitated to kill Kenobi, given the chance, Kenobi could not kill his old friend. Instead, Kenobi made Hett swear on the honor of his father that he would leave Tatooine and never return, hoping that Hett would see the error of his ways and again take up the Jedi way.
� Kenobi removing Hett's wrappings, after defeating him.:"Decades later, I learned that very moisture farm had concealed Anakin Skywalker's son—and that Anakin Skywalker, as Darth Vader, had turned Sith and betrayed the Jedi Order."
- ―Darth Krayt, speaking to Cade Skywalker[src]
Decades after his duel with Kenobi, Hett learned that the moisture farm Kenobi had stopped him at concealed the son of Anakin Skywalker; he would also learn that Skywalker had become Darth Vader, the being responsible for so many Jedi deaths. Upon the realization that Skywalker and Vader were in fact the same person, Hett regretted protecting Skywalker's secret of massacring a tribe of Tuskens, which the young Jedi had confided to him during the Clone Wars. Hett felt that if he had turned young Skywalker over to the Jedi Council, he would have spared the galaxy untold amounts of suffering and grief.
More than one hundred years after the event, A'Sharad Hett, now the Sith Lord Darth Krayt, would retell the details of the duel to his prisoner, the former Jedi Cade Skywalker. The direct descendant of Anakin Skywalker, Cade would choose to follow his ancestor's footsteps and accept the offer to be trained in the ways of the Sith.
