The Non-Canon Expert looks at the writings of Darth Sidious himself within the Book of Sith to see whether they provide any clues from the Dark Lord’s perspective as to who truly won the Palpatine vs. Mace Windu duel in Revenge of the Sith, and what really happened within the Chancellor’s Office.
This is a Legends story for Darth Sidious that uses a number of Legends sources, most notably the Book of Sith, the novel «Dark Lord: The Rise of Darth Vader» by James Luceno, and the Revenge of the Sith novelization by Matthew Stover. It should be noted that it also uses the film as a source, which is of course Canon.
