  • The novel Dawn of the Eagles reveals that Gul Skrain Dukat deliberately doctored Kira's security file so that she wouldn't be arrested the moment she set foot on Terok Nor. Her original file read, in part, "Confirmed association with Shakaar and Kohn-Ma cells. Probable connection to events at Gallitep, to the destruction of several surface relay bases, to numerous counts of tech sabotage. Possible affiliations with other terrorist groups, including Gertis, Krim..." Her priority status was in the upper hundreds. Dukat changed it to match the description partially mentioned in this episode: "Civilian runner for the Shakaar cell. A minor operative whose activities are limited to running errands for the terrorist leaders. May have participated in minor boundary/curfew infringements." He also dropped a digit off of her status number, making her a low priority.
  • The impact that Opaka had on the Ennis and the Nol-Ennis is revealed in the novel Rising Son. The arc of the episode continues in other DS9 relaunch stories, such as in the DS9 novel: The Dominion: Olympus Descending. The events of this episode are mentioned in Lesser Evil.
  • The Star Trek Online expansion Victory Is Life also revisits the penal moon.
  • Opaka's loss in this episode would be mentioned in many of the numbered DS9 novels, including the DS9 novel: Devil in the Sky.
