Fan Casting Star Wars: Rule Of Excellency

In an alternate universe where Anakin Skywalker left Mustafar unscathed and killed Obi-Wan Kenobi on the high ground, the new Sith Lord managed to save Padme Amidala from death and successfully converted her to the side of The Galactic Empire, while he continues to serve Darth Sidious up until ten years after Order 66, where Darth Vader secretly murders his Master in cold blood and takes the throne for himself, the now Empress Amidala, and their Dark Side children, Luke and Leia Skywalker. However, around seven years after Emperor Vader claimed the galaxy, a new threat begins to arrise in the form of a secret Sith Apprentice of his named Galen Marek, codenamed "Starkiller", who believes his Master is favoring Luke and Leia over him and has assembled an army of Vader's Emperor's Hands and Inquisitors to overthrow the Skywalker family. Now, a new Sith Civil War has broken out inside the very core of The Galactic Empire, as Emperor Vader and his family have to stop this unrest before it gets any worse.
