Golan Trevize is the main protagonist throughout much of Foundation's Edge, and almost all of Foundation and Earth. He is initially described as a junior Councilman in the First Foundation's (Terminus) ruling Council, about 500 years after the breakup of the First Galactic Empire and the life of Hari Seldon (~500 FE). He comes to prominence by openly questioning the validity of the Seldon Plan, and of even questioning the authenticity of a Seldon recording that seemed to coincide exactly with reality. As a result, he is arrested by the then-mayor of Terminus, and exiled into space, supposedly to search for the still-active Second Foundation.
