[Star Wars] What exactly was the prophecy from the prequels? Did it get fulfilled? When/how, and why or why not?
gpt
As the Jedi understood it, the prophecy was that the Chosen One would destroy the Sith and in so doing bring balance to the Force.  

It's hard to say what they meant by 'balance', but regarding the destruction of the Sith, the prophecy was fulfilled by Anakin, the Chosen One, when he killed the Emperor at the cost of his own life, and in so doing destroyed the last of the Sith.
