Okay. The RotJ idea has been scrapped. Chapter twenty-one is seen exclusively through the eyes of the main villain, his thoughts and interactions contrary to them. He sizes up all the protagonists and calculates what he needs to do to overcome particular personalities. But even the main villain can't foresee other events and politics that plague the arena he steps into. But he may know how to manipulate them to his favor.
He too has to worry about getting killed from outside sources.
It is funny how scenes and chapters are shaped. Inspired by one thing and then melt completely into something else. Everything has a starting place, I guess.
b write black.
