Morgan Everett

Morgan Everett is, in Deus Ex, the leader of the Illuminati. He resides in Paris, although the exact location is kept secret to all but his most trusted accomplices, such as Toby Atanwe.

Prior to Deus Ex
Everett became leader of the Illuminati after his predecessor, Lucius DeBeers stepped down. He was responsible for creating Morpheus, an Artifical Intelligence which later became Echelon III, leading to the creation of Echelon IV, Daedalus, Icarus and Helios. He was mentor to a young Bob Page, who later broke away from the Illuminati to form Majestic-12.

Events of Deus Ex (2052)
Everett responds to a contact request sent by JC Denton from Beth DuClare's secret routing station. After requiring him to prove his loyalty to the Illuminati, he allows JC into his headquarters and sends him on a mission to meet X-51, a group of scientists who left Area 51 for moral reasons. He later makes contact again, via JC's Infolink, and tries to persuade him to return power to the Illuminati by killing Page.

Events of Deus Ex: Invisible War (2072)
It is unclear what has become of Everett by the time of the sequel. The Illuminati is now being led by Chad Dumier and Nicolette DuClare; whether this means Everett has retired, died, or been deposed, is unknown.
