The Non-Canon Expert explains why we’ve seen Darth Sidious come to the defense of Tarkin so many times within the current Canon as seen in the earliest years of the Empire, even appearing to take Tarkin’s side over that of his own Apprentice Darth Vader. To answer this question, we look at the long history between Palpatine and Tarkin and why the Sith Lord found Tarkin to be a powerful ally in creating his new Empire. This is a Canon story for Tarkin, Darth Vader and Darth Sidious with information from numerous Canon comics and novels, including the «Tarkin» novel by James Luceno, the Darth Vader Annual #2 and the 2017 Darth Vader comic. I hope that you enjoy it!
