This is just an idea Auxiliary chapter for my next upcoming Star Wars story which will be focused on the Beginning of the Sith Order and and go through the all the wars including the formation of the Sith Empire, the fall of the Sith Empire, and then reconstituted Sith Empire.
The Story will follow through this timeline and tell the story of the Main character throughout that time. That is the first part of the fic which will be about 400-500 chapters, while the next part will be the events after the Sith are defeated and lead up to the Galactic Civil War.
Keep in mind that this is just the basic storyline and will most likely change as I start drafting the story and getting ideas.
