''Terok Nor'' is a trilogy of novels and a part of the ''Literature/StarTrekNovelVerse''.

It details the backstory to ''Series/StarTrekDeepSpaceNine'', including the Cardassian annexation of Bajor and the early lives of several major characters (chief among them [[Characters/StarTrekDeepSpaceNineGulDukat Dukat]], Odo, Kira Nerys and Ro Laren). It also features a number of established supporting characters, filling in their lives and backstories as well.

Advertised as part of ''Literature/StarTrekTheLostEra'', it also contains many a ContinuityNod to the ''Literature/StarTrekDeepSpaceNineRelaunch'' books.

The three novels are ''Day of the Vipers'', ''Night of the Wolves'' and ''Dawn of the Eagles''. The first book was written by Creator/JamesSwallow, the other two by S.D. Perry and Britta Dennison.

----
!!This series contains examples of:
* AnyoneCanDie: Anybody who isn't [[SavedByCanon seen onscreen]] in the ''Deep Space Nine'' television series can die in ''Terok Nor''.
* ArtificialGravity: The Tzenkethi create multiple gravity envelopes aboard their starships, allowing them to comfortably use the walls and ceiling just as readily as the floor.
* AsTheGoodBookSays: The Bajoran equivalent crops up. Not literally the bible, of course, but essentially in their culture quoting the prophecies is the same base trope:
--> "I’m a tanner, come from a long line of tanners. It’s a respectable position, you know, working the skins. ‘And as the tradesman plies his wares, so the tanner scrapes the hides, so the ranjen studies the Word’. That's a direct quote from the Book of Seasons, isn’t it?"
* BlessedWithSuck: Miras Vara. Her spiritual awakening in ''Night of the Wolves'' may be for the good of Cardassia, but her new life is hardly a happy one, seeing as [[spoiler: she has to give up her old identity and live on the run as an outlaw]]. Then there's her prophetic knowledge of her planet's future destruction, which she knows she is powerless to prevent. She sees it regularly in her dreams, and is haunted by the vision.
* TheCameo:
** Garak appears briefly in one scene, despite having no part to play in the plot. He isn't named, though. His codename, Agent Regnar (established in ''Literature/StarTrekDeepSpaceNineAStitchInTime'') is used instead.
** David Gold of the ''Literature/StarfleetCorpsOfEngineers'' makes an appearance near the end of the first book.
** Lieutenant Alynna Nechayev (who will eventually rise to the rank of Admiral) is part of a Starfleet Intelligence covert insertion onto Bajor, just before the Occupation gets underway.
* CantKillYouStillNeedYou: The reason why Hadlo initially allies the Oralian Way with the Central Command for the diplomatic mission to Bajor; the Cardassian Government is starting to clamp down and imprison members of the church throughout Cardassian space, and the cleric rightly believes that if he can make his group essential to diplomatic relations with the Bajorans, it will ensure their continued survival.
* TheCassandra: Miras Vara again. Also Hadlo, whose orb vision in ''Day of the Vipers'' allowed him to see the future destruction of Cardassia. He couldn't, however, convince a sneering Dukat that the latter man was taking their people down the wrong path. [[spoiler:As Dukat destroys his ship, Hadlo dies screaming that Dukat will lead Cardassia to the burning cities of his vision.]]
* LesCollaborateurs: Kubus Oak, and the level of his collaboration explains why the provisional government later exiled him.
* ContinuityNod: In the ''Literature/StarTrekDeepSpaceNineRelaunch'' books, Istani Reyla was introduced as a beloved childhood teacher to Kira Nerys. Given that Kira's childhood is partly explored in ''Terok Nor'', Istani makes an appearance more to reinforce the Relaunch backstory than to serve any purpose to the plot.
* DeliberateValuesDissonance[=/=]NoWomansLand: Cardassian women typically aren't allowed to serve on active duty or work other similarly dangerous jobs after marriage, and infertile women typically have the marriage annulled and are outcast [[spoiler:(as happens to Corat Damar's fiancee Veja Ketan, a war correspondent, in ''Night of the Wolves'').]] On the other hand, Gul Malyn Ocett rose as high as she did in large part ''because'' of her infertility, and women dominate Cardassian research roles.
* DramaticIrony: In the classic Season 1 episode "Duet" we learned that [[spoiler: Cardassian filing clerk Aamin Marritza felt great shame and guilt for standing by and doing nothing while the Bajoran prisoners at Gallitep labor camp were killed]]. However, we learn in ''Night of the Wolves'' that [[spoiler: Marritza is unknowingly responsible for Gallitep's liberation. During a conversation with a scientist, he hints at Gul Darhe'el's plans to massacre the entire camp. Said scientist turns out to be a Bajoran informant who passes along the information to the Shaakar resistance cell, thus setting the liberation in motion. It makes his attempt at atonement and subsequent murder in "Duet" even more tragic]].
* DramatisPersonae: All three books have one, along with a mini-glossary.
* DudeWheresMyRespect: Skrain Dukat certainly feels underappreciated by the Central Command:
-->Dukat considered the place where he found himself: isolated from Central Command because of the independent streak he had exhibited during the Talarian conflict...No matter that it had won him many battles! Reviled by Kell for daring to defy the jagul, for shining a light on the corpulent fool's lack of progress with the Bajorans, and in an uneasy partnership with Ico and the Obsidian Order.
* TheEvilsOfFreeWill: Not in the extreme, literal form, but Cardassia has very little tolerance for irregular thinkers, and spreads propaganda insisting that those who behave differently are psychologically and neurologically ill:
-->“People with beliefs like that usually have a disorder that prevents them from understanding loyalty to anything but their own desires. A defect in their lateral cortex makes them abnormally egocentric, and the same disorder keeps them from having any impulse control. I learned about it in socio-deviance.”
* FalseFlagOperation: In the leadup to the Occupation, the Cardassians stage a number of attacks on Bajoran ships, blaming them on the nearby Tzenkethi Coalition. This eventually culminates in a raid on Bajor itself using a hijacked Tzenkethi raider, giving the Cardassians an excuse to station more and more of their ships in Bajoran space, so they can protect their Bajoran "allies" from the evil, invading aliens.
* FantasticCasteSystem: The Bajoran ''D'Jarras''. Darrah Karys is of the artisan caste, a particularly high-ranking one. In choosing Darrah Mace as a husband, she married below her station.
* FantasticMeasurementSystem: Cardassian ''decas''.
* FantasticRacism: All over the place. The Bajorans discriminate against those of lower or higher castes, while the Cardassians are frequently speciesist (for a non-Bajoran example, regarding the Talarians on their rimward border, against whom the Central Command is waging a punitive war, as an infestation of vermin).
* FantasticRankSystem: This series makes use of Cardassian ranks listed in unpublished RPG sourcebooks. From highest to lowest, the ranks are Legate (canonically established), Jagul, Gul (canonically established), Dal, Dalin, Glinn (canonically established), Gil, Garresh, and Gorr. These ranks are later used elsewhere in the ''Literature/StarTrekNovelVerse''.
* FixFic: ''Day of the Vipers'' reconciles the longstanding ContinuitySnarl of the Bajoran Occupation's exact length (which was initially established as 60 years in "Emissary" before going back and forth between 40 and 50 years throughout the remainder of [=DS9=]). ''Day'''s fix is that the Cardassians make first contact with Bajor in 2318. Over the next decade, they slowly begin entrenching themselves on the planet until formally occupying Bajor by 2328 (and not ending until 2369). In other words, the 40 year and 50 year lengths are ''both'' correct. The Occupation's ''official'' length is 40 years, while the ''unofficial'' length combines those 40 years with the preceding 10 years of gradual entrenchment.
* ForegoneConclusion: It's a prequel series, after all. The first novel is going to end with Cardassia taking control of Bajor and occupying the planet. The third will end with Bajor's liberation when the Cardassians withdraw. And anyone who appeared in ''Deep Space Nine'' will survive the story.
* FormerTeenRebel: Gar Osen, more or less.
* GoodIsOldFashioned: Danig Kell and many other Cardassians dismiss the Oralian Way out of hand, claiming that its adherents' devotion to a peaceful faith and opposition to imperialism are weaknesses modern Cardassia can't afford.
* GoodOldWays: The Oralians represent the remnants of the old Cardassia - a far gentler culture.
* GoodShepherd: Kai Meressa, certainly. Hadlo counts, although he has his dark side too, being willing to sacrifice some of the dissident sects to preserve the mainstream Oralian faith. Bennek is a somewhat ineffectual although well-meaning example, in over his head but possessed of very strong conviction.
* HoistByTheirOwnPetard: Dukat's patronising obsession with Kira -- wanting to protect her for her mother's sake and show her the 'error of her ways' -- means he deliberately thwarts numerous opportunities for her to be captured. Which leaves her free to take part in crucial missions that undermine the Cardassian Occupation.
* HorribleJudgeOfCharacter: While there are some exceptions, many of the Bajorans fall for the Cardassian's schemes and see them as kindred spirits and good allies in the decades leading up to the Occupation. Conversely, many Bajorans dislike the Federation because of their mostly secular government, society, and embrace of science over theology.
* IDidWhatIHadToDo:
-->The morality of a Cardassian can only be understood by a Cardassian. The morality of a soldier of the Union is that which serves the Union best.
* IdiosyncraticCoverArt: Minus the printing, the covers of the trilogy together form a triptych, seen above.
* IdiosyncraticEpisodeNaming:
