Kaleth Kaleth , or the Temple of Knowledge was one of nine temples of the Je ' daii Order located on the lush and dangerous world of Tython . A large stone structure with four large , square towers , the temple at Kaleth served as a repository of knowledge and wisdom for many generations . After the devastating Force Wars , the Je ' daii left Tython and others came to live in the ruins of the ancient fortress - city . By the time the Jedi Order returned to their ancient homeworld during the Cold War between the Galactic Republic and the resurgent Sith Empire , the temple at Kaleth was no more than ruins . History . Pre - Republic era . Long before the Tho Yor arrived on Tython with the first Force - sensitives that would form the Je ' daii Order , a civilization of Kwa inhabited the planet , constructing temples and structures on the forested planet . Eventually the world was depopulated and the Kwa temples fell into ruin . When hundreds of philosophers and scholars from across the galaxy first arrived on Tython in 36 , 453 BBY , they were brought forth from the stars on giant pyramidal constructs called the Tho Yor . These nine massive ships scattered across the planet and landed in separate locations , releasing those held within to settle the planet . The Tho Yor themselves would serve as the very foundations for these travelers ' new homes and places of study . One of these Tho Yor landed in the Tythos Ridge , and would come to be known as Kaleth — a Je ' daii word meaning " sanctum " . The philosophers , calling themselves the Je ' daii Order , established a stone structure below the massive floating ship , encasing within it the ancient ruins of one of the Kwa temples . Above all other temples on the world , Kaleth was the most important as it served as the meeting place of Je ' daii leaders and a convocation center for the entire Order . Kaleth was where critical matters arose , where decisions were made and judgment rendered on behalf of the entire Order and the location of the Je ' daii ' s vast library . For this reason , when the Despot War erupted in the Tython system , the forces converged on Kaleth during the climatic close of the war . At all times a Je ' daii Temple Master served as steward of the facility and oversaw its functions . In 25 , 793 BBY Master Kora Ryo , a Twi ' lek , was the Temple ' s overseer . During his research , the Zabrak Je ' daii Master Ters Sendon discovered the ancient Kwa temple deep in the lower levels of Kaleth and stumbled upon an ancient holocron of the Kwa philosopher A ' nang . With the assistance of Je ' daii Journeyer Tasha Ryo , the holocron was activated and its gatekeeper offered to give of its knowledge . After years of study and peace , the Force Wars erupted between members of the first Jedi High Council and the heretical Master Rajivari . Rajivari and his followers holed up in the Temple of Knowledge as their former brother and sister Jedi converged on them . While Rajivari fled , his followers all perished leaving behind only data files containing their final moments . At the conclusion of the war the Jedi Order abandoned Tython , leaving Kaleth and the other temples to crumble . Despite this , other Force - wielding civilizations from the nearby worlds in the system would attempt to recolonize Tython . Taking up occupancy in the old Temple of Knowledge , Kaleth became a city of sorts , with each successive government attempting and failing to bring Kaleth back to its heyday . Two such rulers were the Forceful Lord Maravada the Silent and later Avamarivash the Warrior - Poet . Despite their different ruling styles and ideals , both their reigns eventually came to an end and the city remained in ruin , their legacies sealed away within the Chamber of Speech . Return of the Jedi . Following the rediscovery of Tython by Jedi Master Satele Shan , the Jedi Order relocated their headquarters to their ancestral homeworld to replace their Coruscant Temple destroyed at the end of the Great Galactic War . Upon locating Kaleth , many Jedi believed it would be an ideal foundation for their new Temple . Despite this , the Jedi High Council decided that it would be more wise to study Kaleth from a distance and chose to construct their new Temple in a nearby valley just north of the site . Setting up an archaeological camp at the site of the ruins , the Jedi were startled to find ancient wardroids that attacked any who entered the site ; if Jedi designed the droids , why were they killers ? Unbeknownst to Tython ' s new residents , the droids had been designed by an ancient Jedi known as the Weapon Master to protect the First Blade , the template for the modern lightsaber . Master Till ' in led the team that sought to discover the reason for the droids ' attacks and hoped to unlock the mystery surrounding the ancient fortress . Layout . Located in the western Tythos Ridge , Kaleth was nestled into the embrace of a gently - sloping mountain range . Accessible by two roads , one of which was called the Elarian Trail , the massive fortress was made of painted stone , arranged to create large geodesic circles in the faces of the four square towers . Following centuries of not being occupied , the stone walls of Kaleth fell away until all that remained were the lower stories . The entrance to the temple - city remained in the form of a massive stone archway that opened into a spacious courtyard where a towering statue kept watch over the entrance . Many small structures existed in the area , stairs led up to the few remaining levels . Various chambers were still occupied by war droids which were programmed to attack any intruders . A short path from one of the upper levels led into the mountain behind the city and contained the lost Chamber of Speech , a repository of historical records relating to the city - temple ' s past .
