The Galaxy was on fire as the flames of the Clone Wars ravaged the galaxy. In its second year, the Republic gathered its strength and launched campaign after campaign to make up for its losses in the first year.
The Confederacy under the Sith Count Dooku and General Grievous prepare their own legions of battle droids for their conquests as well but none of them could prepare for when space and time cracked opened all around the galaxy.
In mere seconds entire armies and fleets disappeared as this new strange force appeared. The force seemed so strong that it corrupted dozens of planets and billions fell to a murderous rage. A few force users attempted to contain this unknown energy only to be corrupted and fell to the same rage and madness which corrupted billions.
Under pressure by its people to defeat this energy the governments of the Republic and Separatists joined forces as a disturbance in the Force grew stronger around Coruscant, the Capital of The Republic.
