Malachor Malachor was a rocky , hellish wasteland planet shrouded in mystery . It was the location of an event known as the Great Scourge of Malachor , which took place thousands of years before the conflict between the First Order and the Resistance . During the reign of the Galactic Empire , Jedi Master Yoda told Ezra Bridger , a Padawan , to find Malachor to help him defeat Darth Vader and the Inquisitors . Description . Malachor was a barren planet located in the Outer Rim Territories , and had a Sith temple located underneath its surface . Its surface resembled an ocean of liquid carbonite that had flash - frozen . Small , pyramidal , solid stone foothills are located equidistant from each other on the surface of the planet . Along Malachor ' s central latitude was a large crater ringed by narrow spires . History . Early history . At some point , the Sith were able to establish a presence on the planet Malachor , constructing a massive temple beneath its surface . This temple held a colossal kyber crystal that was used to power the temple . Thousands of years before the brewing war between the First Order and the Resistance , the planet was the location of a massive battle , in which the Jedi Order launched an all - out assault against the Sith when the temple ' s weapon misfired and petrified everyone on the planet . After these events , Malachor was made forbidden to the Jedi , though stories of what had happened were passed down , forming the basis of many legends . Millennia later , the debris of war still littered the battlefield . After Sith Lord Darth Sidious took the Nightbrother Maul as his apprentice , the two of them traveled to Malachor . There , Sidious showed Maul a vision of the battle between the Sith and the Jedi . Due to its infamy , Malachor was often invoked as a curse word . While contemplating his strategy for getting himself and his team of astromech droid s off the desert world of Abafar , Colonel Meebur Gascon exclaimed that there was " no way in Malachor " that he would lead his team on an assault on a Separatist landing field . Years later , during the reign of the Galactic Empire , the crime lord Cikatro Vizago of the Broken Horn Syndicate used Malachor as an epithet while working with the smuggler Lando Calrissian . Age of the Empire . During their rebellion against the Empire , three rebels — the Jedi Kanan Jarrus and Ezra Bridger , along with Ahsoka Tano , a former Jedi — traveled to the Jedi Temple on Lothal to seek the spectral guidance of Jedi Master Yoda in the hopes of defeating the Sith Lord Darth Vader and his Inquisitors . Yoda told Bridger that , if he and the others wanted to fight , they had to find Malachor . After helping the Phoenix Cell establish a base on Atollon , Kanan , Ezra , and Ahsoka traveled to Malachor together . On Malachor , the two Jedi and Ahsoka discovered a deep chasm which led to an ancient Sith temple . There , the three friends were attacked by an Inquisitor known as the Eighth Brother . Ezra was separated and fell into a tunnel . There , he encountered the former Sith Lord Maul , who also wanted to defeat the Sith . Maul befriended Bridger and the two joined forces to venture into the temple in order to find the " secret " that could destroy the Sith . Working together , the two retrieved a Sith holocron from the temple . Ezra and Maul then reunited with Kanan and Ahsoka , who were being attacked by the Eighth Brother , the Fifth Brother , and the Seventh Sister . After Maul drove the Inquisitors away , Maul convinced Ezra and the others that they had to enter the Temple in order to activate the Holocron . He claimed that doing so would give them the knowledge they needed to destroy the Sith . The Inquisitors soon caught up with them . While Kanan and Ahsoka fought with the Inquisitors , Maul sent Ezra to bring the holocron to the top of the temple . Meanwhile , Maul killed the Inquisitors before turning on Kanan and Ahsoka . He blinded Kanan but was stopped by Ahsoka . While Kanan pushed Maul off the cliff , Ahsoka went to deal with Ezra . Meanwhile , Ezra planted the holocron into the temple ' s obelisk . He encountered a female voice who revealed that the temple was an ancient Sith superweapon capable of destroying all life . Ezra refused to use the Temple ' s knowledge and was attacked by Darth Vader , who had arrived in his TIE Advanced starfighter . Ahsoka arrived and dueled with Vader , while Kanan and Ezra joined forces to remove the holocron . Since the Temple was building up a power charge , the removal of the holocron caused it to implode . Kanan and Ezra managed to escape before the Temple closed in on them . Vader survived , leaving the temple wounded and Tano was pulled away from the collapsing temple into world between worlds by Bridger , surviving the event . Later , Tano departed the world between worlds and walked into the Sith temple . Behind the scenes .
