Kathol ( planet ) Kathol was a planet in the Kathol system , which gave its name to Kathol sector . History . In ancient times , the planet was the homeworld of the ancient race known as the Precursors or Kathol ( also spelled Cthol ) , and it shared the Kathol system with several other worlds , and the two massive launch gate s , hyperspace portals that the Precursors had used to colonize many nearby systems . At some point during the Galactic Republic , more than a thousand years before the Battle of Yavin , a Dark Jedi attempted to seize control of the native biotech , and in particular the Force - manipulating device known as the Codex . The resulting conflict led to the cataclysmic destruction of one of the launch gates , ravaging the planet Kathol and the surrounding space . Apparently anticipating just such a contingency , the native Kathol had prepared a device which could store their life energy and intellects in non - corporeal form . A number of them managed to survive the energy surge by fleeing into this Lifewell , leaving a caretaker creature to maintain and restore their world in their absence , with the assistance of their arachnid servitor species , the Charr Ontee . The task of reviving the Precursors themselves was entrusted to the female Human Jedi Knight named Halbret , who had led a group of Jedi against the invading Dark Jedi , and entered a long - term hibernation trance after helping the Precursors enter the Lifewell . However , the caretaker creature grew content with the power the Precursors had bequeathed to it . The creature — later known as DarkStryder — kept the disembodied Precursors trapped in the Lifewell , placed Halbret in a stasis tube to prevent her awaking , and ruled Kathol as a tyrant until defeated and destroyed in the early years of the New Republic . By this time , Kathol was home to a bewildering variety of sentient lifeforms . There were the Charr Ontee , who had remained largely loyal to their masters ' memory , and who were also the parent race of the Charon , and also the Fiery One s , energy - beings who had appeared after the Rift Disaster , and may have been in some way related to the Kathol . But there were also a variety of new servitor species created by DarkStryder for its own purposes , or simply its own amusement — the worm - like Segmi and amorphous Maoi , the arachnid Krakai and Ssamb , the canine warrior Yapi , the arachnoid / avian Zizimaak , and a race of stunted humanoid slaves bred from Kathol stock , known as the Yimi or " Servants . " Over time , the presence of the living energy of the ancient Kathol in the Lifewell had become inexorably intertwined with the wider Force energy - field on the planet , and transformed it into what became known as the Ta - Ree , which all the native sentients could use to some extent . Kathol had three continents , of which the most important was the northern continent , where the ancient Kathol capital had been built ; by the time of the New Republic , this metropolis had decayed , leaving only the bony skeletons of organic skyscrapers , plus DarkStryder ' s fortress above the Lifewell , and the haphazard terraforming carried out by the Charr Ontee . To the west of the northern continent was the Zizimak Archipelago , a chain of tall , volcanic spires which were the center of the bird - arachnoid Zizimak civilization , and beyond this lay the western wasteland , more sparsely - populated , and shared between Zizimak and Segmi groups . The southern wasteland , to the south of the central sea , was almost deserted , but it was home to a Charr Ontee enclave and a " hive " of Fiery Ones ( perhaps the central home of that species ) , while the southern polar ice - cap was home to a rogue tribe of Yapi .
