After the final battle on Jakku in 'The Force Awakens', Luke and Rey leave to go to Tatooine to meet Mara Jade, as well as Luke's young son, named Jayson. They then leave to go throughout the Galaxy and reunite the New Jedi Order, hoping to receive answers of the ancient evil they face. Once they begin their journey, they reunite with one of the first of the new Jedi Luke trained, Tsabb Bri, a Rodian Jedi. He informs them that he has found a name of an ancient being, one so close to the force, she became a being of pure darkside; Abaloth. They then travel to Ahch-To, home of the first Jedi temple, in hopes of finding answers about Abaloth. Once at the temple, they meet a woman who has been hiding at the temple since the end of the galactic civil war, and claims to have worked with Anakin Skywalker. Her name is Ashoka Tano.
Meanwhile, Han, Leia, Lando, Poe, Finn, Udic, and the Mandalorian learn that a major benefactor of the First Order is a female Hutt named Szuumo the Hutt. They learn she resides on Coruscant, and go there to track her down, in hopes of disrupting most of the First Orders finance. Once there, however, they learn a much bigger secret about the First Order. A secret that changes everything.
