Cerberus: The Illusive Man

Mass Effect 2
The reclusive tycoon calling himself the Illusive Man is a human nationalist focused on advancing human interests, whatever the cost to non-humans. The Citadel Council regards him as a fanatic posing as a serious threat to galactic security.

A mysterious maverick to say the last, the Illusive Man heads the Cerberus network. Dubbed "the Illusive empire" by investigators, Cerberus is al allegedly untraceable syndicate of private intelligence agencies, biotics laboratories, engineering and scientific research teams, and lucrative front companies.

Branded a terrorist and seditionist organization by authorities, Cerberus is the only human power base other than the Terra Firma Party strong enough to embarrass -- if not threaten -- the Council and its human representatives.
