Three years before the Battle of Yavin, the temple was visited by Jedi Knight Kanan Jarrus, his Padawan Ezra Bridger, and former Jedi Ahsoka Tano as they sought knowledge for how to defeat the Sith Lord Darth Vader and his Inquisitors. This event later became known as the Great Scourge of Malachor. During the battle, the superweapon fired, killing and petrifying all combatants-Jedi and Sith. The Jedi soon caught wind of the Sith's plan and launched an assault on the temple. The infernal machine at the heart of the Sith temple, a superweapon powered by a giant kyber crystal, was capable of destroying life. Millennia before the rise of the Galactic Empire, the Sith constructed a pyramidal temple on the bleak world of Malachor. ' My apprentice is activating the temple, or more precisely, this battle station, which I shall use to exact my revenge on all my enemies!' ―Maul to Ahsoka
