Second Foundation
The Second Foundation was founded by Hari Seldon as a budding colony of psychologists and mentalics, people with telepathic abilities, located "at Star's End", an intentionally obscure term used by Seldon, which is later revealed to refer to the planet Trantor. In "Forward the Foundation", the original Second Foundation is revealed to also include Hari's own granddaughter, Wanda Seldon, and his bodyguard Stettin Palver.
