After years of Civeil war, the Separatists have battered the already faltering Republic nearly to the point of collapse. On Coruscant, the Senate watches anxiously as Supreme Chancellor Palpatine aggressively strips away more and more constitutional liberties in the name of safeguarding the Republic. Yoda, Mace Windu and their fellow Masters grapple with the Chancellor's disturbing move to assume control of the Jedi Council. And Anakin Skywalker, the prophesised Chosen One destined to bring balance to the Force, is increasingly consumed by his fear that his secret love, Senator Padme Amidala, will die.

As the combat escalates across the galaxy, the stage is set for an explosive endgame: Obi-Wan undertakes a perilous mission to destroy the dreaded Separatist military leader, General Grievous; Palpatine, eager to secure even greater control subtly influences public opinion to turn against the Jedi; and a conflicted Anakin - tormented by unspeakable visions - edges dangerously closer to the brink of a galaxy-shaping decision. It remains only for Darth Sidious, whose shadow looms ever larger, to strike the final staggering blow against the Republic...and to ordain a fearsome new Sith Lord: Darth Vader.
