Dairine uses her new power to travel to Mars, then to the Crossings, where she is attacked by agents of the Lone Power. When she uses a worldgate to flee, assisted by an unnamed man she meets in a bar, she finds herself on a giant planet consisting entirely of silicon. In the meantime, Nita and Kit discover she is missing and chase after her. Dairine awakens the massive computer embedded in the planet and gets to work designing and naming 'mobiles' after the planet begins to create quicklife (computer-based) creatures. She names them in a variety of ways ranging from computer programs to Star Wars characters.
