Hey, sorry about the wait... I have been busy lately, but I hope the short story guide tided you over. Well anyway, here is my Dark Times timeline:

"For over a thousand generations the Jedi Knights were the guardians of peace and justice in the Old Republic. Before the dark times, before the Empire."
-Ben Kenobi

The Dark Times range from Revenge of the Sith (19 BBY) to A New Hope. In this third disection of the Rise of the Empire Era, the Jedi Order is hunted to near-extinction and the evil Emperor Palpatine gains complete control over the galaxy. This era has been written in a few times before the release of Episode III, but with the release of the movie, this era will be expanded upon in multiple sources. A series of young-adult books, Last of the Jedi, is being released, the first of which is already available. A novel set shortly after Revenge of the Sith, Dark Lord, will be released this fall, followed by a series of 3 novels, Coruscant Nights. Also, the comic series Republic will explore this era starting with issue #78.
