Duel near the Omen A duel occurred in 5000 BBY , in the wreckage of the " Omen " , a Sith dreadnaught that crash - landed on the uncharted planet of Kesh during the Great Hyperspace War . The battle was waged between the half - brothers Yaru and Devore Korsin , over who would command the rest of the " Omen " surviving crew . After a tense argument in the remains of their ship , Devore , who desired his brother ' s post as captain of the " Omen " , attacked Yaru while under the influence of Red Rage spice . The lightsaber duel continued outside the teetering dreadnaught , and , although Devore briefly gained the upper hand , Yaru regained the advantage after using the ship itself as a weapon . After being hit squarely in the shoulder by one of the " Omen " torpedo tube doors , Devore ended up covered in rubble just meters from the edge of a steep cliff — although Devore was incapacitated , Yaru decided to drop his brother off the ledge to his death . Prelude . In 5000 BBY , at the height of the Great Hyperspace War , Dark Lord of the Sith Naga Sadow sent the Sith dreadnaught " Omen " on a Lignan mining and delivery mission to the planet Phaegon III ' s largest moon . Among the " Omen " crew were Yaru and Devore Korsin , half - brothers with a contentious relationship — Yaru was mission leader , while Devore headed the mining team . As the " Omen " prepared to transport their Lignan crystals from Phaegon III to their destination on the planet Kirrek , a Jedi attack resulted in the ship being knocked off course as it jumped to hyperspace . The severely - damaged " Omen " crash - landed on an uncharted planet known as Kesh . Although the Korsin brothers both survived the crash along with many of the crew , tensions soon arose over which Korsin would command the rest of the castaways , and the remaining Sith on Kesh were in dire straits . Desperate to find a way off Kesh , Devore unsuccessfully searched the " Omen " wreckage in the Cetajan Mountains . Defeated , Devore collapsed in the captain ' s chair and took a dose of Red Rage spice . Yaru soon entered the ship as well , similarly trying to discover a means to facilitate their escape . An argument ensued between the two brothers , regarding whether there was any hope for their survival — eventually , Yaru broached the subject of a meeting that Devore had with Naga Sadow shortly before the mission started , where Devore unsuccessfully petitioned for command . Things grew more tense between the Korsins , and Devore , under the influence of spice , reacted in an outburst of rage and attacked . The duel . His natural rage and strength enhanced by the Red Rage spice , Devore used his connection to the Force to create a whirlwind , which turned nearby debris , including jagged pieces of transparisteel , into weapons that caused superficial wounds to Yaru ' s face . Yaru was able to shield himself before he took too much damage , and he flung his brother out of the teetering " Omen " . However , as Yaru stepped out of the ruined starship , he was distracted by a large winged creature that seemed to be observing the battle . That diverted Yaru ' s attention long enough for Devore to gain the upper hand , throwing Yaru against the " Omen " wreckage . Emboldened by his advantage , Devore proclaimed himself to be the true " Commander Korsin . " From there , the fighting turned into an all - out lightsaber duel , although Devore found his furious attacks repeatedly parried . Thinking on his feet , Yaru attempted to fire a torpedo from the " Omen " exterior tubes by manipulating the control box from the outside — however , the doors were partially stuck in the ground , and , although the torpedo did not emerge , the doors hit Devore in the shoulder and sent him flying . Devore came to a stop at the edge of a sheer cliff overlooking a nearby ocean , and , partially covered with rubble , he was gravely wounded and unable to see . Although Yaru considered helping his brother , he decided against it , allowing Devore to drop off the ledge to his death . Aftermath . By chance , the battle was witnessed by native Keshiri female Adari Vaal , who was riding the winged uvak that had distracted Yaru during the duel . With her help , the surviving Sith convinced the rest of the Keshiri that they were their gods , the Skyborn , with Yaru proclaimed as Grand Lord of Kesh . The crew of the " Omen " and their descendants formed a Sith tribe that survived for thousands of years . Devore Korsin was not forgotten by his family — although his wife , Seelah , married Yaru and had a daughter , Nida , with him , she secretly plotted to avenge her husband ' s death . Her plot was carried out in 4975 BBY , when Seelah arranged for her and Devore ' s son , Jariad , to attack Grand Lord Korsin with a group of Sith warriors . Although Yaru died during the skirmish , Jariad was also killed and Seelah incapacitated . Nida , who fought along with her father , became the new Grand Lord . Behind the scenes . The duel first appeared in " " , a 2009 eBook written by John Jackson Miller . It was also briefly featured during the eBook ' s follow - up , " " , along with mentions in sequels . An image of Adari Vaal observing the duel was included in the 2012 reference book " The Essential Reader ' s Companion " .
