Fanfic idea: What if the Emperor died before the events of The Original Trilogy?
In this version there is no Operation Cinder or Exegol. And if you want to follow the prophecy
you could say that Vader unintentionally caused the Emperor’s death by feeding him out of date fruits or something like how Persus in Greek Mythology accidentally killed his grandfather he was propheciced to kill by a an accidental discus throw.
I suggested this idea before but the more i think about it the more like it.
Basically the Emperor SOMEHOW dies before the events of the OT and it initially cause a power vacuum that results in Thrawn and Vader in charge.
Since the Emperor isn’t around to dissolve the Senate maybe it remains for a while as a symbol with no real power.
Without the abuse or control of the Emperor Vader undergoes a severe risky surgery to improve his cybernetic body that was intentionally made faulty by the Emperor to make him independent of him so he can now survive without his mask and suit.
Without the Emperor and the now current leadership of Thrawn and Vader Thrawn is put in charge of imperial fleet and Vader in charge of the Death Star. Neither of them particularly liked the Death Star. Thrawn thought it was an over ambitious vanity project and Vader isn’t eager to use it since he primarily wants to bring order to Galaxy so the Death Star isn’t used to destroy Aldeeran.
Other ideas with this scenario: if Alderran isn’t destroyed Leia remains captive but Vader can sense something about her so he refuse to execute her.
If the Falcon still gets captured maybe Ben gets captured by Vader instead of killed and even if Falcon is tracked to Yavin 4 Vader and Thrawn doesn’t take the bait and keeps the Death Star away from Yavin 4 so they can upgrade the defenses of the Death Star instead sending Star Destroyers there so the rebel has to evacuate.
I’m just throwing out ideas: I just think it’s interesting to think how the Empire would work without the arrogant leadership of the Emperor and how Vader’s potential redemption would now work without an Emperor for him to kill.
Also another thing to consider in the OT Vader wanted to Luke to join him because he feared that the Emperor would hunt him down if he didn’t. Without the Emperor Vader’s approach to this would be different if Vader is in fact genuinely partially in control of the Empire in this version.
Also I think it would be funny if Vader sent Mara Jade to spy on Luke and they still hook up in this timeline.
