The Combined Army is humanities greatest threat. Guided by the Evolved Intelligence a combined force of alien races has set their eyes on the Human Sphere. Through a wormhole next to the planet Paradiso their scouting forces have already attacked the Human Sphere multiple times.
The E.I. is ALEPH’s nemesis. Through the efforts of the E.I.’s combined forces the Human Sphere has already suffered some severe losses. The E.I. forces are independent and fully autonomous, and are able to undertake a campaign without the support of the Combined Army’s other forces. This makes the Combined Army a fathomable foe.
The Combined Army’s forces are all conquered by the Evolved Intelligence. After these races were conquered, they joined the Evolved Intelligence in its quest for transcendence since it saw a role for them. It seems like the E.I. has seen some role for humanity as well.
