Incidentally, the plot of Episode 3 focused on the Republic becoming an Empire, with the Jedi being driven away from the Republic. The Chancellor becomes an Emperor, and the Jedi rally around Anakin, putting their trust in the most powerful and (to their eyes) most pure Jedi Knight. The Emperor recognizes that Anakin is their champion, and invites him to his palace to negotiate a peace between the Jedi and the newly formed Empire. Anakin knows it is a trap, but he knows also that he must take any opportunity to end this destructive conflict without further bloodshed. Obi-wan meets with him before he goes, telling him that it will surely result in his death. He asks Anakin to run away with him into exile, but Anakin knows that he must meet the Emperor, and thinks less of Obi-wan for wanting to run from his problems. He goes and meets the Emperor, and the Emperor begins talking about how poor Obi-wan was as a teacher. He says that Obi-wan once trained a Jedi Knight before he was ready, and that he ran away and left his apprentice, a mere learner, when he needed his master the most. He says that this Jedi became Darth Vader, a servant of the Emperor. Anakin doesn't know what the Emperor is talking about, as he thought that he was Obi-wan's first apprentice, but in the darkened throne room, a place strong with the Dark Side of the Force, he suddenly sees a visage of this fallen apprentice, this Darth Vader, of which the Emperor speaks. He fights with this phantom warrior, but we never see the end of the fight. The Emperor later tells the galaxy that the Jedi's champion has been defeated, and he reveals his secret apprentice, Darth Vader. The Jedi flee to their stronghold, a place known only to them and Anakin, and Obi-wan goes into exile. The Empire has won, and the galaxy falls into dark times, awaiting the arrival of a new hero.
