From the introduction:
It is the year 22 BBY, several days after the battle of Battle of Geonosis and the beginning of a historic conflict between the Galactic Republic and the Confederacy of Independent Systems. Grand armies of clones and droids battle across the galaxy causing strife and chaos wherever they go and the Jedi, once seen as benevolent protectors and peacekeepers, now serve as generals and warriors under the command of the Republic. For each faction involved this war represents something of tremendous importance. For the Jedi and the Republic it represents their duty to maintain peace and order and prevent everything they've built from falling apart. For the Confederacy and their allies it represents their chance to gain independence from the corrupt and failing Republic. For bounty hunters and other major criminal elements it represents an unparalleled opportunity to gain wealth and power. And for the ancient order of the Sith, hidden from even the ever vigilant eyes of the Jedi, this war represents the culmination of a nefarious plan to destroy their enemies forever and take control of the entire galaxy.
