The Prophesy of Balance
I don’t think anyone has really explored this yet but what do we think the actually prophesy is? I know Mace Windu referred to “The Prophesy on the One who will bring balance to the Force” but what does the “bringing of balance” actually refer to?
What if the Prophesy actually foretells the destruction of the Jedi Knights and Sith. Or even more interestingly what if it actually details the rise of Palpatine & Vader and the Empire, the role of Luke Skywalker and everything. I would not expect it to actually contain their names, that would be too much of a giveaway but if the events are foretold then this could explain why the Jedi Council were so unwilling to act at first.
