Foundation and Earth

Councilman Golan Trevize has decided in favour of Galaxia. Gaia is a superorganism, a planet with a unified consciousness where every dewdrop, every pebble, every being can speak for all—and feel for all. But is it the right choice for the destiny of humanity? Trevize believes the answer lies on the legendary Earth, the planet where humanity's roots lie. But no one believes it exists. No one is sure where the planet of the galaxy's first settlers is located.
