Five years before the events of the movie, Philippe San Simeone and several other members of CONSENT noted the shifting balance of power within the CONSENT. Forming a private armed civilian organization, they financed rebel activity against CONSENT to ensure stability in the Earth Sphere. However, there are rumors that the organization has existed in secret for over seventy years, even before the collapse of the Earth Federation. The organization consisted mostly of CONSENT defectors, and are based in Side 4.
Prior to the events of G-Saviour, a criminal organization known as Marchosias, attempted to take over Side 4. A Marchosias Bugu entered the colony and attacked the metropolitan area before being stopped by the G-Saviour. Marchosias was wiped out after the Illuminati destroyed most of its space forces.
Light of Gaea
During the battle of Gaea, a squadron of Illuminati's mobile suits, numbering about twice the amount of CONSENT mobile weapons, engaged various Bugus and Rais. Their intervention lead to the Gaea's victory and subsequent declaration as an autonomous region by CONSENT. Following these events, the political landscape became unstable within the CONSENT and thus the Illuminati resolved to interfere as a third-party.
After the appearance of the Gremly Sheep unit of the Congressional Armed Forces, and the Project Raven program, both led by the militaristic Colonel Bais Bashing, the Illuminati sent the Lightning Squad to investigate and destroy the threat.
