Great Calamity The Great Calamity was an event remembered in the legends of the Keshiri species on the planet Kesh . The Calamity was caused by a massive conflict between the Protectors and the Destructors , resulting in the reshaping of the very surface of the world . The legends were based on Keshiri memories of an ancient conflict between Jedi and Dark Jedi who had become stranded on Kesh following the Hundred - Year Darkness . They fought a fierce struggle which devastated large areas of Kesh ' s surface and terrorized the Keshiri natives . Eventually , the two warring factions decided to make peace and the Dark Jedi agreed to seal their " great weapon . " These Force - users then migrated to the polar continent of Eshkrene in the planet ' s South Pole where they established a new neutral Force order which became known as " the Doomed . " History . Origins . The Great Calamity ' s roots can be traced back to the Hundred - Year Darkness , which marked a major schism between the orthodox Jedi and dark side - wielding Dark Jedi . These Dark Jedi pioneered the science of Sith alchemy and created various Sithspawn including the serpentine Leviathans , serpentine beasts which devoured the life energies of other beings . After decades of fighting , the Dark Jedi were defeated at the Battle of Corbos around 6900 BBY and the Jedi and Galactic Republic reasserted control over the galaxy . Some Dark Jedi including Karness Muur , Remulus Dreypa , and XoXaan escaped the conflict and fled into the Stygian Caldera . These Dark Jedi discovered the planets Korriban and Ziost along with the native red - skinned Sith species . The Dark Jedi used their Force powers to take control of the Sith and created the first Sith Empire . Through this cross - cultural contact , the term Sith became synonymous with the dark side - wielding Sith Order , which would pose a major threat to the Jedi and the Republic in the preceeding millennia . After a period of consolidation , Dreypa and several other exiles decided that it was time to leave the Stygian Caldera and take their revenge on the Jedi and the weakened Republic . Dreypa and his followers managed to acquired a large starship and several Leviathan larvae from the Sith Lord Sorzus Syn ' s laboratory on Korriban . Dreypa ' s ship managed to navigate its way out of the tricky Stygian Caldera . However , they encountered a group of Jedi veterans from Corbos who were still scouring the galaxy to hunt for their Dark Jedi opponents . After a pursuit across the galaxy , the Jedi and Sith ships crash landed on Kesh . Jedi versus Sith . After landing on Kesh , the Jedi and Dark Jedi fought a fierce battle which would engulf the planet and threaten the indigenous Keshiri , a purple - skinned humanoid species . Kesh ' s unusual magnetic field prevented both sides from calling for reinforcements of leaving the planet . During the Great Calamity , Dreypa ' s Dark Jedi followers unleashed several great weapons including Leviathans which devastated much of Kesh ' s surface . Many Keshiri were killed and many settlements were destroyed during this fighting . Eventually , even Dreypa ' s Dark Jedi became disillusioned with the destruction they had wrought on Kesh . With their leader Remulus Dreypa unable to see reason and end his quest for vengeance , his Dark Jedi followers sealed him within an oubliette where he would remain in stasis for nearly four millennia . The two rival Force orders then made peace and began a process of reconciliation . Since Kesh was still isolated from the rest of the galaxy , the Jedi and Dark Jedi agreed to withdraw from the Keshiri whom they had threatened . One Jedi starship also survived the conflict . Since the survivors had agreed that no one who was Force - sensitive could ever leave the planet , they decided to hide the vessel in the Keshiri burial cairns beneath the city of Tahv . However , they still preserved this knowledge in the event that they had to leave Kesh . These Force users eventually traveled to the frozen continent of Eshkrene , which was situated in Kesh ' s South Pole . On Eshkrene , these former Jedi and Dark Jedi established a new community known as the Doomed who regarded Force - sensitivity as a curse rather than an extraordinary advantage . They sought to find true neutrality in the Force in order to balance both the light and dark sides . For four millennia , the Doomed and their descendants remained on Eshkrene . They would later use ice image s to monitor the Lost Tribe of Sith , another group of stranded Force - users who arrived during the Great Hyperspace War . Legacy . The Great Calamity was not the only incident when Sith Exiles tried to threaten the Jedi and the Republic . Another conflict was fought between the Jedi and Sith prior to the Great Hyperspace War . However , in this case the Jedi won and and reported this news to the Jedi Council . The ancient Keshiri would remember the Great Calamity as a clash between two powerful groups of god - like entities known as the Protectors and Destructors . This became connected to an earlier Keshiri legend about the Skyborn , a powerful sandy - blooded race of god - like beings , who had fought against the malevolent Otherside — beings of fire , rebellion , sickness , and death — during the Great Battle . In 5000 BBY , another group of Sith exiles from the Sith Empire became stranded on Kesh after their ship " Omen " was damaged during the Great Hyperspace War . Most of these Sith exiles were enslaved Human miners and ship crew who had been tasked with delivering a shipment of Lignan crystal s to the Sith ' s Dark Lord Naga Sadow . By that period , the descendants of the Dark Jedi exiles had cohabited with the indigenous Red Sith and carved up a sizeable regional empire . However , contact with the Republic in 5000 BBY led to the Great Hyperspace War which culminated in the collapse of the Sith Empire . Under the leadership of Yaru Korsin , the Human Sith assumed lordship over the Keshiri on Keshtah Minor by claiming that they were the legendary Protectors who had come down from the stars to visit their planet . These Sith became known as the Lost Tribe of Sith and would rule Kesh for several millennia . Despite their self - exile to Eshkrene , the Doomed still monitored developments in the other parts of Kesh . By 2975 BBY , the Lost Tribe under the leadership of Grand Lord Varner Hilts had annexed Alanciar and embarked on a maritime exploration program . This set in motion a chain of events in 2974 BBY which brought the Lost Tribe into contact with the Doomed . Behind the scenes . The Great Calamity was first developed as a plot element by John Jackson Miller . It first appeared in " Lost Tribe of the Sith — Spiral 2 " , the second issue of the " " comic arc , which debuted on September 12 , 2012 .
