Star Wars alternate endings : Emperor Vader

It a felt like forever since yoda had arrived on dagoba, every moment taking hour’s just for 1 minute to pass, yoda decided to find some sort of house to live in, where he would spend the rest of his year’s hiding and meditating. Sensing a massive disturbance in the force, yoda could only think of how he had failed to stop the emperor and that he felt that obi wan had failed to get rid of Darth Vader, Knowing what the sith were like, he only assumed that Vader had destroyed sidious and clamed the emperor’s throne for himself. Yoda admitted to himself that he was very scared that if Vader was to find him that he would have nothing to do than to just run threw the forestry swamp or give himself to Vader.
“ I am sorry old friend, I never wanted any of this to happen” Yoda heard a voice come out of nowhere in the swamp, then he remembered
“qui-gon, is it you?” yoda whispered to the mist,” yes, master yoda, I have discovered the way to eternal power, I can only talk to you for the moment threw the force and I need to help you, or you and the rest of the Jedi will become extinct” qui gon answered, “No…Jedi will never be extinct, the force lives in every being, some better than others, Jedi will always exist as long as the force does, and unfortunately the sith will always exist to” yoda replied, “ But now if we do not stop Vader, the Jedi will not return for ages maybe even thousands of year’s, and the galaxy will be in fear for to long to accept Jedi again”qui gon said, “stop him, we can not, too powerful he has become, not even I can stop him, now, rest I must” yoda yawned, ”No.. Vader must be destroyed, Anakin is trapped by his demons that were brought out by fear and sidious, I have a plan that will help Anakin wake up and come back to the light, destroying Vader and the empire” qui gon said,
Plan? Hear it. I will, if not, no hope there is for the galaxy and the Jedi” yoda sat down prepared for what ever qui gon has to say.
