Five centuries after the conclusion of "Earthfall", there is only one original colonist from Harmony: Shedemei, who now wears the Cloak of the Starmaster (a device that links her to the Oversoul).

After hundreds of years, the Oversoul still has not achieved its original purpose: to find the Keeper of Earth, the central intelligence that alone can repair the Oversoul's damaged counterpart at Harmony.
