Palpatine appoints Anakin to the Jedi Council as his representative and informant. The Council allows Anakin as a member, but declines to grant Anakin the rank of Jedi Master, and orders him to spy on Palpatine, diminishing Anakin’s faith in the Jedi. Palpatine tempts Anakin with his knowledge of the dark side of the Force, including the power to prevent death. Meanwhile, Obi-Wan travels to Utapau, where he kills Grievous, and Yoda travels to the Wookiee homeworld of Kashyyyk to defend it from a Separatist invasion. Palpatine reveals to Anakin that he is the Sith Lord Darth Sidious and that he knows how to save Padmé. Anakin reports Palpatine’s treachery to Mace Windu, who confronts the Sith Lord with three other Jedi masters. Palpatine easily slays the three masters, but is subdued by Windu, who uses his lightsaber to return Palpatine’s Force lightning, disfiguring him. Fearing that he will lose Padmé if Palpatine dies, Anakin severs Windu’s hand, allowing Palpatine to throw him out the window. Anakin pledges himself to Sidious, who dubs him Darth Vader. Palpatine then issues Order 66, which commands the clone troopers to betray and kill their commanding Jedi officers. Meanwhile, the newly knighted Vader brings with him the 501st Legion to help kill the remaining Jedi in the temple including the younglings (the children in training), before traveling to the volcanic planet of Mustafar to slaughter the Separatist leaders. Palpatine soon declares himself Emperor before the Galactic Senate, transforming the Republic into the Galactic Empire, and declaring the Jedi as traitors. Having survived the chaos, Obi-Wan and Yoda return to Coruscant and learn of Vader’s betrayal. Yoda orders Obi-Wan to confront Vader while he deals with Palpatine.
