Kay Eaton was a science fiction writer who wrote under the pseudonym of "K.C. Hunter" in the 1950s in order to conceal the truth, from the more conservative elements of that era, that she was in fact a woman. She is best known for her work from the New York based Incredible Tales magazine.
Kay often worked in conjunction with her husband Julius Eaton and the two had something of a reputation among the magazine staff for turning out slightly sentimental stories, particularly by Herbert Rossoff. Because she was a woman, and consequently discriminated against, Kay felt some solidarity with Benny Russell, the staff's only African-American writer.
When Benny submitted his story about a space station, Kay was particularly impressed with the character of Major Kira Nerys, saying science fiction needed more strong women. (DS9: "Far Beyond the Stars")
Kay Eaton appears in the novel Star Trek: Typhon Pact: Raise the Dawn as a vision experienced by Kira, where she helps Cassie rescue Benny Russell after his transfer to prison, the vision inspiring Kira to save Sisko by seemingly sacrificing herself.
