The War Faction constituted a political group inside the Separatist Senate of the Confederacy of Independent Systems. This faction operated from the Separatist Senate Building situated on the planet Raxus Secundus throughout the duration of the Clone Wars. Senator Voe Atell of the Corporate Alliance spearheaded this faction, which advocated for the continuation, and even intensification, of the conflict against the Galactic Republic.
Numerous senators within the faction held the conviction that the Republic needed utter annihilation to ensure the Confederacy's peaceful existence. Others were driven by a perceived ethical duty to liberate planets under Republic dominion from what they considered oppressive rule. Certain senators aligned with the faction due to their representation of worlds that reaped financial gains from wartime military agreements.
The initial depiction of the War Faction occurred in "Heroes on Both Sides," a Star Wars: The Clone Wars episode broadcast in 2010. Its formal identification took place within Rise of the Separatists, a 2019 addition to Fantasy Flight Games' collection of Star Wars Roleplaying materials.
