Red Sith Purge In 4985 BBY , Yaru Korsin , leader of the Lost Tribe of Sith on Kesh , launched a full - fledged purge of the forty - five pureblood Sith on the planet . Ravilan Wroth , the leader of the members of the Sith species in the Lost Tribe , had embarked on a plot to poison the water supply of the city of Tetsubal , in order to convince the Lost Tribe leaders to focus on finding a way off - planet — by then , the Sith had been stranded on the remote world for fifteen years . However , his ploy was discovered by Yaru Korsin ' s wife Seelah , who framed him for similar deadly incidents in other neighboring towns . Convinced that Wroth and the purebloods needed to be eliminated , Korsin enacted a purge that lasted through a single night , and though the purebloods fought back with everything they had , they lost more and more of their ranks throughout . Eventually , Wroth was taken prisoner as the last remaining purebloods fought back against Yaru Korsin and his lieutenants in a last stand high in the Takara Mountains . While the last holdouts were killed , Wroth was executed by Seelah Korsin ' s son Jariad , and the bodies of the dead were put on public display in the city of Tahv . With the purge , all of the non - Human members of the Lost Tribe of Sith — save for the Houk Gloyd , a personal friend of Yaru Korsin — had been wiped from the face of Kesh . Prelude . In 5000 BBY , a Sith starship known as the " Omen " was knocked off course during a hyperspace jump and crash - landed on the remote planet Kesh . After a chaotic first few nights in the mountains where the " Omen " came to rest , the Sith found their way to a relatively primitive civilization of Keshiri natives . Posing as the Keshiri gods , the Sith quickly took their place as rulers of Kesh . The " Omen " crew had contained a sizable number of pureblood Sith , of whom only fifty - seven remained when the Sith made it out of the mountains . By 4985 BBY , twelve had died due to general misfortune , and no pureblood Sith children had survived more than a day . Meanwhile , the Human population of the Lost Tribe of Sith flourished . The most prominent member of the purebloods on Kesh was Ravilan Wroth , who often represented his compatriots in front of Lost Tribe leader Yaru Korsin . However , Wroth had his own gripe with the Lost Tribe , as he wanted Korsin to withdraw his people from Keshiri affairs and focus on finding a way off Kesh . To that end , Wroth came up with a plan — on a research trip to the Ragnos Lakes region , Wroth decided to poison the water supply of the city of Tetsubal in order to create the appearance of a deadly virus ravaging the planet . Wroth successfully carried out his plan , using the compound cyanogen silicate to kill all 18 , 000 Keshiri residents of Tetsubal . However , his plan was discovered by Yaru Korsin ' s wife Seelah , who , already holding a prejudice against the purebloods , decided to frame Wroth for further crimes . Korsin performed the same deadly deed on seven other towns near Tetsubal , killing hundreds of thousands of Keshiri . Seelah was able to present her husband with the information that Wroth and his retinue had visited all those towns in recent days , as well as evidence that he had access to cyanogen silicate . Convinced of Wroth ' s complicity in the deaths , Korsin proclaimed that it was time for the non - Human members of the Lost Tribe to be eliminated . The purge . In a single night , all of the " Fifty - seven , " as the non - Human Sith of Kesh were known — except for the Houk Gloyd , a close friend of Yaru Korsin — were killed . The Fifty - seven did not go quietly , fighting the Lost Tribe assassins throughout the darkness in the mountains , though they could not withstand the attack for long . A young sentry was trapped and killed , never abandoning his post until the bitter end . Another prominent member of the Fifty - seven , the cyborg translator Hestus , was personally brought down by Seelah Korsin herself . The dead were beheaded and put on display in a plaza in the city of Tahv , even while the remnants of the Fifty - seven still held out against Yaru Korsin and his chief lieutenants . The final living members of the Fifty - seven were driven to a last stand high in the Takara Mountains , close to the " Omen " original crash site . No quarter was given , and Yaru Korsin threw any who surrendered over the side of a cliff . Meanwhile , the wounded Ravilan Wroth was brought to the plaza where those already killed were displayed . Confronted by Seelah Korsin , Wroth admitted his complicity in the deaths at Tetsubal , but not in any of the other cities . Revealing her deception , Seelah took credit for those deaths , as well as the deaths of all the infant pureblood Sith who had been born on Kesh since the " Omen " crash , saying that Wroth and his people would have done the same to Seelah and her kind eventually . With that , Jariad Korsin , Seelah ' s son , emerged from the darkness and killed Wroth , completing the purge . Aftermath . With that , all of the non - Human crewmembers of the " Omen " , save Gloyd — who himself would perish along with Yaru Korsin in a lightsaber duel ten years later — were killed . Little did the Lost Tribe know that their purge was secretly supported by a Keshiri resistance movement dedicated to overthrowing Sith rule on Kesh . Tilden Kaah , a secret operative of the resistance movement and the personal attendant to Seelah Korsin , brought the news to resistance leader Adari Vaal immediately after the purge ' s completion . Although the Lost Tribe suffered a population loss due to the purge , it was more than made up for by a rapid increase in births over the next decade . In the years following the bloodshed of the purge , Yaru Korsin looked on the purge as an unfortunate but ultimately necessary event , as a homogenous Lost Tribe was easier to rule . Little knowledge of the Fifty - seven or the purge survived for very long , as Seelah Korsin took steps to erase them from history . Still , Keshiri tales spoke of " deformed " crewmembers of the " Omen " and their elimination . In fact , by 3000 BBY , there was an active political faction on Kesh known as Force 57 that was comprised of physically imperfect members of the Lost Tribe , who revered Ravilan Wroth and the original Fifty - seven . Behind the scenes . The purge of the Fifty - seven first appeared in John Jackson Miller ' s 2010 eBook , " " . The event was also mentioned in two subsequent sequels , " " and " " , along with the 2012 reference book " The Essential Reader ' s Companion " . In his production notes for " Paragon " , Miller revealed that he used the purge as a " story springboard " to move the Lost Tribe from its more diverse form seen in the Sith of the " " comic book series to the homogenous kind found in the later " " novels .
