@danaan:

I envision the Battle of Coruscant as taking place near the beginning of Episode I.

For a time after its first appearance in Episode II, the Empire works with the Alliance to defeat the clone menace.

There is a loose parallel to the cooperation between the Western Europeans and Americans with the Soviets in the fight against the Third Reich. Two ideologically contrasting entities in a temporary alliance against a more pressing threat (IRL the Nazis, in this series the clones)

In Episode III, the Clone Wars are over, but the Alliance has become a Rebel Alliance, due to the Empire having turned on its previous agreement and overtaken many of the Alliance's star systems.

Episode I is about surviving to fight the clones another day and taking the first steps towards being a Jedi Knight.

Episode II is about finding out who the real enemy is. I'm thinking of titling it in reference to a line delivered by McGuiness in ANH...Star Wars Episode II: The Dark Times Begin.

Episode III can be summarized perfectly by, "If you strike me down I shall become more powerful than you can possibly imagine."

I'm aiming for a bittersweet ending, because the protagonist, Anakin's apprentice Ben, has to die for a cause that won't see victory for another twenty years. But the twins are safe and sound...

Out of remembrance, Obi-Wan adopts Ben's name as an alias during his exile on Tattooine.
