"A long time ago, in a galaxy far, far away…"
Originally drawn from the galactic timeline spanning from just after "Revenge of the Sith" to the beginning of "A New Hope" (although taking from before is certainly applicable), Star Wars-1 takes the cannon of the Star Wars movies and adapts it to the Multiverse. A designation that has existed for the last few years in the Multiverse, this setting represents the changes that have happened in recent times to the Galaxy.
Vader has become Emperor and his apprentice raised up to an official Sith — no longer a mere acolyte. The Jedi still operate within the galaxy, but the Imperial forces are stronger in most systems; it is, in fact, treason for anyone to be a Jedi, regardless of rank. Force users are hunted down and eliminated if they do not join in the Empire, but there are always those who fall through the cracks.
The Path of the Light, neutraility, or to fall to the Dark Side — only you can choose your destiny.
