Taken to a small, closed-off spaceport, Walt and Don are told that they are to participate in the construction and flight of humanity's first interstellar spaceship, one equipped with a space-warping hyperdrive.

After extensive physical and psychological testing, Don is assigned to work on the starship's propulsion and Walt is to help develop the control circuits.

Bringing Vittoria down on that planet obliges Walt and Don to take one of the ship's small rocket shuttles down to the surface and set up a landing radar.

One day Walt and Don are taken alone to the nearby Ainsath city and led to an old woman, who reads from a book that mimics Genesis up to the Tower of Babel and then deviates from it.

After receiving a noisy reception at Peak City Spaceport, Walt, now Starman Hansman, is ready to head back out to the stars.
