On Harmony, the colonists established the Oversoul - an artificial intelligence, monitoring the planet with a small army of satellites. It also influences the actions of humans. Though it does not prevent them from doing evil, it keeps their destruction limited by suppressing any thoughts that might lead to things like long-distance travel or instant communication. Thus the technology on Harmony includes basic computers, presumably without advanced Internet capabilities, although the Oversoul was used for basic data transfer, and solar-powered handheld energy weapons, but no cars or even wagons.
The Oversoul, designed to last only twenty million years, eventually begins to break down. It decides to send an expedition back to Earth to seek advice from the entity of which it is an imitation: the mysterious Keeper of Earth. Soon after, the people begin to receive dreams similar to those that the Oversoul sends; these come directly from the Keeper of Earth, demonstrating faster-than-light transmission on its part.

When the Oversoul realized that it was in danger of decaying completely without having completed its purpose, it began influencing certain humans to breed so that their descendants would have greater and greater ability to hear the Oversoul. In The Memory of Earth it begins directly instructing these people to engineer a return to Earth, in the hope of receiving instructions from the Keeper of Earth, on which the Oversoul was modelled
