The Eye of Sion arrives at Peridea, the ancient homeworld of Morgan's people—the Nightsister witches—who were the first to harness the purrgil and travel between galaxies. Morgan, Baylan, Shin, and Sabine meet the Great Mothers, three Nightsisters still living on Peridea who are allies of Thrawn and who used their Force magic to call Morgan to them. Baylan reveals to Shin that he is searching for a great power on Peridea that he learned about in Jedi folktales. He hopes to use this to end the cycle of war and destruction between the light and dark sides of the Force, as seen with the fall of the Jedi and rise of the Empire. Thrawn arrives aboard his Star Destroyer, the Chimaera, and honors Baylan's promise by providing Sabine with provisions and a mount to search for Ezra.
In the aftermath of the fall of the Galactic Empire, the galaxy remains in a fragile state of recovery, caught between the remnants of Imperial forces and emerging factions vying for power. Amidst this turmoil, Ahsoka Tano, once a Jedi Padawan under Anakin Skywalker, now stands as a rogue force in a galaxy still struggling with the scars of war. After severing her ties with the Jedi Order during the Clone Wars, Ahsoka has wandered the galaxy, seeking to help where she can, though always keeping her distance from the institutions and ideologies that once shaped her life.
Ahsoka's searches for answers as a shadowy new threat emerges in the galaxy. Having already encountered the darkness that lurks within the Empire, she begins to sense a growing power tied to an ancient and forgotten evil that may be stirring once again. As she delves deeper into this mystery, Ahsoka's journey takes her to new corners of the galaxy, where she confronts not only dark forces but also the lingering ghosts of her past. The memories of her former mentor, Anakin Skywalker - now Darth Vader - haunt her, and she must wrestle with the weight of their history together.
On her journey, Ahsoka encounters a variety of figures, both new and familiar. One of the most prominent is Sabine Wren, a former rebel and Mandalorian warrior who, like Ahsoka, has endured great loss. Together, they begin to piece together the threads of this new threat. They must prevent Grand Admiral Thrawn - who is stranded in another galaxy - from returning and uniting the remnants of the Empire against the fledgling New Republic. As Ahsoka unravels the secrets of this growing dark force, she will have to decide whether she can truly walk alone, or whether, in the face of an ever-changing universe, she can find the allies and the courage to forge a new way forward.
