 * The DS9 segment ties into the events of Warpath, Fearful Symmetry, and The Soul Key.
 * is thanked in the for "The Mirror-Scaled Serpent" as a reference source.
 * Sarah Shaw is a pseudonym of David Mack. Due to a mix-up in the Pocket Books editorial department, Mack had been contracted to provide two stories in the Star Trek: Mirror Universe anthology collections. Since the offers could not be rescinded, the editors requested that Mack write one of the stories under a pseudonym, which he himself derived – Shaw. Mack noted that working under the pseudonym "freed me up, in a sense, to approach Saturn's Children with a different style. I wrote it much more quickly than I normally do, and by imagining I was a different author I ended up working from a different mindset. It was an intriguing experience."
 * Different versions of the mirror Janeway, the mirror Torres, and the mirror Annika Hansen previously appeared in Dark Passions, Book Two.
