Part of it takes place before the events of Solo and focuses on Lando and L3-37, Lando’s droid sidekick. Part of it takes place between Solo and A New Hope, and that focuses on Han and Chewie, where we meet Sana Starros for the first time. Part of it takes place post-Return of the Jedi, and that’s where we see Han, Leia, a very young Ben Solo, and Lando come into the story.
