Luke Skywalker has returned to Pinnacle Base with Kam Solusar, a Jedi knight [sic] he rescued from the dark side of the Force and whose father, Ranik, was murdered by Darth Vader.
Meanwhile, in a dreaded turn of events, Emperor Palpatine has again taken a youthful clone body and renewed the determination of Military Executor Sedriss and his elite Darkside Warriors.
Unaware of the Emperor's return, the leaders of the Rebel Alliance gather to hear a daring strategy: Lando Calrissian and Wedge Antilles will intercept a cargo of Imperial war droids and use them to attack the Emperor's citadel on Byss.
Luke Skywalker disagrees with the plan, but Mon Mothma overrides him and encourages Luke and Leia to continue their search for lost Jedi. As Mon Mothma says, "It is now clear that the future of the New Republic depends on the revival of the Jedi knights [sic]."
Luke and Kam Solusar plan to investigate the planet Ossus, an ancient center of Jedi culture. Leia, pregnant with her third child, will journey with Han Solo to New Alderaan to be with their twin children. En route, they will visit Nar Shaddaa in hopes of finding Vima-Da-Boda, the old woman who gave Leia an ancient Jedi lightsaber.
