The beauty of the Star Wars saga is its fictional universe that is ripe for endless characters & stories. This has not only been explored in movies & TV shows, but also video games.

They are almost like awesome mini-movies in themselves & show the amazing creative possibilities that that Star Wars galaxy presents.
This trailer is for an expansion to the game. It follows a force-weilding child who is trained and corrupted by the Sith Emperor Valkorion, the leader of the Eternal Empire, who lived 5,000 years before Emperor Palpatine.
