Luna was the Cardassian daughter of Gul Edet in the mirror universe, and Elita's half-sister. She spent much of her youth in her father's company while he oversaw an Alliance slave-labor camp on Khefka IV. She often watched slaves, including Stephen April, toil through a window of her residence. A similar version of this character, with the same background, existed in an earlier continuity mirror universe on Star Trek: Arcadia. This version was still a child during events which took place in 2379.
