Then what’s the finale?
“What are looking at me for?” Listen to Starkiller.
EDIT: I haven’t got a clear plan in mind, but I would like to see a finale with the main focus on the fight against the FO and especially the civil fleet. Ideally Ben and Rey should lead them from the falcon. Some sort of a Stormtrooperrebellion or at least a scene of Kylo freeing these enslaved soldiers would be a great addition too.
EDIT2: And most importantly we should never see Exegol or cultist. Our protagonist’s obsession with the past and legacies should literally be the distraction, which keeps them from defeating the FO.
On top of that I would like to imply, that the obsession with the past and their predecessors, namely the Empire or Exegol (just invent another ancient Sith-Empire) should be the thing that keeps the FO running.
