After finding the Separatist encampment, Obi-Wan fights Grievous and kills him with an abandoned blaster. When Palpatine—who is secretly the Sith Lord Darth Sidious, the mastermind of the war—issues Order 66 to have the clone troopers turn on the Jedi, Obi-Wan survives the attempt on his life and escapes, rendezvousing with Yoda and Senator Bail Organa (Jimmy Smits) of Alderaan aboard Organa's ship, "Tantive IV". Returning to Coruscant, he and Yoda discover that every Jedi in the Jedi Temple has been murdered. After sending a beacon to all surviving Jedi to scatter across the galaxy and remain in hiding, a distraught Obi-Wan watches security footage revealing that it was Anakin—who is now Sidious' Sith apprentice, Darth Vader—who led the chaos. Yoda says that he will confront Sidious, and he charges Obi-Wan with battling Vader. Obi-Wan is loath to fight his best friend, but reluctantly accepts when Yoda says that Anakin Skywalker no longer exists, having been “consumed” by Vader.
