The Last Castle was originally published in Galaxy in April, 1966. It won the Hugo Award and the Nebula Award. The Last Castle is the first of two Jack Vance stories to be published in the Tor Doubles series.
The Last Castle is set on a future Earth that humans have abandoned and later returned to. With their return, they brought a civilization which was based on a strong caste system Gentlemen were humans who lived in the castles which were established across the planets. Other humans, Nomads and Expiationists, lived outside the castles and were viewed as barely more than animals. Serving the Gentlemen in the castles were the Peasants, Phanes, Birds, and Mek, various races which were brought back to Earth with the humans in order to perform certain tasks.
