Knight's tour

Kaston Iago once used the knight's tour in an attempt to show Elska Blayes the extent of her own freedom. He instructed her to clear the all the pieces from the chess board and for one of the knights to be placed on any square of the board, and told her to consider a knight with total freedom of movement once all the other pieces have been removed from the game. In the analogy, the knight was Blayes. She was still stuck with the movements of the Knight and will never land on the same square more than once as she goes round and round, but she'll always return to her original position. It is a complete circuit, a trap. (AUDIO: Storm Mine)

The sequence is never named in the audio story as the knight's tour.
