Z'ymira the Huntress was a fictional character from the storybook The Kingdom of Elysian, written by Benny Russell.
She was portrayed as a female archer in the magical Kingdom of Elysian.
During the 23rd century, Doctor Joseph M'Benga often read this children's book to his daughter, Rukiya. His daughter loved the book, except for the fact that she hated the fact that Z'ymira had never met Sir Adya, whom she always imagined would team up.
Still, in the actual story, Z'ymira and Adya never knew each other, as they had never even met each other. In 2259, when an entity in a nebula transformed the crew of the Enterprise into various characters from that book, it was Una Chin-Riley who took on the role of Z'ymira, sporting her bow and arrow.
She rescued Joseph M'Benga, Hemmer and Erica Ortegas from getting killed by Queen Neve's Crimson Guard.
Not long later, M'Benga started to notice that something was different in the fantasy that he was reliving compared to the original children's story from the book. He then immediately realized that Z'ymira and Adya were clearly old friends in this version of the story, and it was even implied that they were in some sort of a romantic relationship.
It was this incident that made it clear to M'Benga that the alien in the nebula must have learned of the story from his daughter's mind, because she never liked the fact that Z'ymira and Adya had never known each other or even met for that matter. (SNW: "The Elysian Kingdom")
