I'm in the process of thinking of Force-related things for my Jedi to do. One idea is to have them aid in recovery efforts through the use of their healing powers, off-setting a shortage of bacta. Or using TK powers to help free civilians from structures damaged by clone fleet bombardments. The Jedi are guardians of peace and justice, right?

As for non-war stuff, I'm considering having the Jedi use their TK to craft awe-inspiring monuments to fallen heroes of yore. They could also use their mental abilities to sooth the minds of others, the lighter side of the Jedi mind trick, which could potentially mediate disputes between belligerent parties.

Since the Empire doesn't show up in Episode I: In the Age of Jedi, there's plenty of opportunity to devote screen-time to showing what was lost when Palpatine and Vader enacted their dark crusade. Then it's time to show how the Jedi are brought to their knees in Episode II: The Dark Times Begin....then finally capping things off with a desperate chase towards the last glimmer of hope left in the galaxy, in Episode III: War of the Skywalkers.

Edit: Still unclear whether I ought to title Episode I In the Age of Jedi or In the Age of the Jedi. Any suggestions, folks?
