Malachor I was an Outer Rim planet located in the Malachor System. It was described as a barren wasteland that was shrouded in mystery. which took place thousands of years before the Great Jedi Purge. During the reign of the Galactic Empire, Grand Master Yoda instructed Padawan Ezra Bridger to find the planet which would help him defeat Darth Vader and the Inquisitors.
“Find Malachor.”—Yoda, to Ezra Bridger
The Sith established a presence on the Malachor, constructing a massive temple beneath the planet's surface. Thousands of years ago, the Great Scourge of Malachor I occured on the planet, causing a great amount of devastation. An ancient lightsaber design with a crossguard lightsaber dated back to this time.
At some point in its history, the planet was the location of a massive battle, in which the Old Jedi Order launched an all-out assault on its barren surface. Following this battle, Malachor I was made forbidden to the Jedi, although stories of what had happened on its surface were passed down, forming the basis of many legends. Even many centuries later, the debris of war littered the surface.
The name Malachor I was used in expressions during the time of the Clone Wars. While contemplating his strategy for getting himself and his team of astromech droids off of 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.
During the Rebel Insurgency where the Rebel Network fought against the Empire, three rebels—the Jedi Kanan Jarrus and Ezra Bridger, along with Commander Ahsoka Tano, a former Jedi Knight—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 I. It was there where they encountered the former Sith Lord Darth Maul, who also wanted to defeat the Sith as well, but unleash a powerful weapon that was meant to wipe out the Empire.
