Sura Novi (Foundation's Edge) is an agent of Gaia (Foundation's Edge) who lives on the planet Trantor (Hame) in the guise of an unmarried Hamish woman. Her full name is Suranoviremblastiran. Foundation Speaker Stor Gendibal detects inconsistencies in her brain that cannot be accounted for, making him aware of the existence of a powerful mentallic agent interfering with the Second Foundation. She goes with him to the Gaia system, and then reveals that she has been part of a large plan to make him go there. After the final confrontation in Foundation's Edge, she erases Gendibal's memories of her being an agent of Gaia, and returns Trantor with him, again (and permanently) disguised as a Hamish.
