Twilight of the Apprentice Part 1.Ezra, Kanan, Chopper and Ahsoka arrive on Malachor - a Sith world long forbidden to the Jedi - in search of knowledge with which to combat Vader the Inquisitors, though Chopper warns them they are not alone as another ship is on the planet. Landing within a massive crater, Ezra accidentally causes the Jedi to fall into an underground cavern - containing a Sith Temple and the site of an immense, ancient battlefield between Sith and Jedi. They soon after find the other ship's owner - an Inquisitor known as the Eighth Brother, who's attack seperates Ezra from Kanan and Ahsoka.
