Heeding the advice given to them by Yoda, Ezra and Kanan travel with Ahsoka to the Sith world of Malachor, where they hope to find the knowledge they need to understand and ultimately defeat the Sith. Ezra joins forces with Darth Maul, who has lived on Malachor for many years in the hopes of unlocking its secrets so he too can destroy the Sith who wronged him so many years ago. Together, they are faced with numerous threats—from Inquisitors to Darth Vader himself.
