Protected by the legendary Jedi Order, the Galactic Republic stood as a bastion of peace in the galaxy for a thousand generations. Several centuries ago, the greatest threat the galaxy has ever known emerged in the form of the dark Sith Empire. After a volatile war, the Republic emerged victorious and the Sith were assumed to be extinct. Nonetheless, the Jedi have maintained a constant vigil over the ancient Sith homeworld, to protect the galaxy from the darkness that still resides in the planet’s tombs.
The latest cinematic looks like it was taken from a movie. That is all.
