When Rex finds a group of scientists looking for nanites, he has to intervene and stop the mysterious 'Architect' from destroying the world!
Having fled Providence, Rex is traveling through a desert when he comes across a construction crew under attack by Gnasht. After Rex intervenes to save them, the foreman Jacob invites him to a nearby optically-cloaked village of engineers, who are working to create communication between the nanites and humans in an attempt to achieve harmony and peace, all under the direction of a mysterious man they call "the Architect".
The idyllic atmosphere and the sense of belonging Rex experiences during dinner with Jacob's family convinces Rex to stay. He offers to help the engineers with the huge antenna at the center of the village, and with his technopathic powers completes it years ahead of schedule. However, he becomes suspicious when he discovers that no one is allowed inside the antenna except the Architect himself.
Rex barges into the tower to discover that the Architect is an android, a creation of the rogue artificial intelligent Zag RS, the computer that is supposedly the base behind the communicator. The AI explains that the nanites constrain its potential, and that the transmitter's actual purpose is to transmit a self-destruct command to all nanites on Earth, which would wipe out all life on the planet.
Rex leads the engineers in a struggle against multiple copies of the Architect to disable the charging antenna, succeeding just in time. Agent Six, who has been tracking Rex via a trail of defeated EVOs, arrives; Zag RS uploads itself elsewhere, and Jacob and the other engineers decide to continue working for humanity in their village in spite of the Architect's betrayal. Rex decides to return to Providence, as he believes in its objective despite his objections to White Knight's leadership, on the condition that Rex, Bobo, Agent Six and Dr. Holiday have dinner together like a family every Friday night.
