Baley, however, confronts Giskard, who admits that Vasilia unknowingly gave him telepathic abilities during experiments when she was a child. Using knowledge derived from Han Fastolfe's mind, Giskard shut down Jander, to thwart Amadiro's attempt to build humaniform robots. Giskard allows Baley to retain knowledge of his abilities, but prevents him (with the help of his telepathic abilities) from revealing the secret. Below is a list of all the major and minor characters in the book, in order of appearance, with plot detail.
