The Prophecy of the Saviour was an ancient Jedi prophecy that depicted the rise of a hero and the vanquishing of a villain, thus saving the galaxy. The Prophecy had been seen three times in the galaxy's history, the first involving Alran Dilu vanquishing the Dark Spirit, the second involving Zorin Durandu vanquishing the ghost of Darth Synthos and the third and final involving Nas Andu vanquishing The Knight of Shadow at the fall of Zarin III. In order to reach their goal, all three saviours had to undergo similar Trials of the Saviour and were rewarded with a specialized Saviour's Lightsaber to defeat the villain.
