Dark Secret

Go To
She's quite nice really, but keeping secrets is hard work.
"My swashbuckling fop cannot take the flaw Dark Secret: Not Gay."

Some characters have some dark, terrible secret in their pasts that they don't want anyone to know. Sometimes they killed someone close to them. Sometimes they're secretly a double agent. Sometimes they took the last cookie from the cookie jar. It doesn't matter how big or small the secret is, it just matters that the person keeping it thinks that it's vitally important that it stay hidden.

There are two standard reactions to these coming out. Either everyone involved is shocked and horrified and lives are ruined. Or it's almost an anticlimax either because they've known all along, or it just wasn't as dark a secret as the keeper thought it was.

When it's a whole town that's doing this it's a Town with a Dark Secret. When you get even bigger in scale you get an Empire with a Dark Secret. When it's society-wide in general, you get Masquerade. My Greatest Failure is a particularly common type of Dark Secret, and it is often an element of a Dark and Troubled Past or a Mysterious Past and revealed in a Troubled Backstory Flashback. Related to They're Called "Personal Issues" for a Reason. See Open Secret for when your secret is not so secret. When they cause you to be suspected of unrelated crimes, they become the Big Secret.

Supertrope to Coming-Out Story, a whole plot trope where the Dark Secret is being LGBT+. May overlap with Beneath the Mask if they care about hiding their true personality from everyone else. Hide Your Otherness may overlap with this if the reasons for it are personal. If the secret is something you can lock up, it will lead to a "What's Inside?" Plot. Compare Old Shame, which also sees a character trying to hide something from their past, however it's due to shame and embarassment rather than it being legitimately troubling or ruinous of their life and others'.

This being a trope about secrets there will be Spoilers ahead.

  • The International Patents Office is the most powerful institution in Rod Duncan's The Fall of the Gaslit Empire trilogy. They came to prominence after "The Great British Revolution" which divided Britain into the Anglo-Scottish Republic and the Kingdom of England and South Wales. The purpose of the Patent Office is to protect humanity by preventing "unseemly science" from advancing and causing harm. The Patent's Office has a Dark Secret. The Patent Office did extreme historical revisions including eliminating mention of the Napoleonic War, which weakened Britain to the point where a Luddite revolution was possible. Additionally the Office did not just prevent the development of new technology, they actually forcibly regressed technology of the past. For example the breech-loading guns of the Napoleonic War is Lost Technology as the guns in the late 20th century are now front-loading, flintlock muskets and pistols. Meanwhile the Office uses some of the prohibited technology, including electrical lighting, for their own benefit. The protagonist's discovery of the Office's secret in 2009 will eventually lead to the Gaslit Empire's collapse ten years after.

  • The Stormlight Archive: The Knights Radiant were an order of magical knights tasked with protecting humanity from the apocalypse. Thousands of years before the story, they abandoned their oaths, as well as their unspeakably powerful arms and armor, for unknown reasons. The current religion claims that they used tricks to pretend divine powers and a holy calling and fled when the charade was discovered, but we see the event at one point, and it's clearly something else entirely. In the second book, Words of Radiance, Taravangian's Diagram says (in code) "Hold the secret that broke the Knights Radiant. You may need it to destroy the new orders when they return."

In book 10, we find out that Hunger aura is a corruption caused by the Monarchs. The Monarchs are ascendant beings who are supposed to leave the world, but who have selfishly decided to stay. The more Monarchs there are, the more powerful the Dreadgods. If all the Monarchs left, the Dreadgods would starve to death within a few decades. It is impossible for a Monarch not to know this, as the world continuously tries to force them to ascend. Any time anyone gets close to this truth, the great powers of the world force them to swear an oath on their soul not to reveal anything, and if they refuse they are forced to ascend.

Ned never made it back for that talk but it was finally revealed that Ned is actually Jon's uncle and his sister Lyanna birthed him, while his true father is Rhaegar Targaryen. Out of respect for Lyanna's wishes, honorable Ned Stark lies not only to his wife and his best friend but the entire world, in order to protect Jon. To make things even more complicated, Jon is not a bastard of theirs either; Rhaegar did not kidnap and rape Lyanna. Instead, the two were in love, with Lyanna leaving willingly with him to elope after he annulled his marriage to Elia Martell. Since Rhaegar's children with Elia were killed at the end of the rebellion, that makes Jon the rightful heir to the Iron Throne, trumping all other claims, including that of his aunt/lover Daenerys. Needless to say, if this secret were to ever become public, it would change the political landscape of Westeros on a monumental scale.

  • Star Trek: Deep Space Nine:
    • "Equilibrium" concerns a dark secret of the Trill, specifically regarding Joran, one of the hosts to the Dax symbiont. The violently unstable Joran was joined with Dax for six months before being joined with Curzon (the predecessor to Jadzia), with a memory block implanted into Dax to wipe all memory of Joran. However, Joran is just the tip of the iceberg, as it's revealed that as many as half of the Trill population is eligible to be joined... but there aren't enough symbionts to go around, and a power struggle to acquire symbionts would ensue should this secret come to light.

  • Star Trek: The Next Generation:
    • Simon Tarses in the episode "The Drumhead" has one that he lied about on his Starfleet application because he feared that he would be suspected because of it. The events of the episode validate that fear: he claimed that his grandfather was Vulcan, when he was actually Romulan. This is arguably more politically than genetically relevant, as Romulans and Vulcans are the same species, or at least very closely related, but Vulcan is a key and founding member of the Federation while Romulus is the centre of the original rival empire to the Federation. Thing is, once this is found out that's the only thing driving the proceedings against Tarses — his personal feelings and political leanings about Starfleet and the Federation aren't even looked at. While the future of his career is uncertain at the end of the episode (the investigation dramatically falls apart, but he did still lie on his Starfleet application), Expanded Universe materials tend to take pity on the poor fellow and have it eventually recover.

  • GURPS has a Disadvantage called Secret. If it's revealed, the character loses the Secret, but gains Disadvantage(s) (or loses Advantages) worth twice as many points as the Secret.
  • The GURPS Disadvantage was inspired by Champions and its system of Disadvantages. The current edition has Social Limitations that include things like Guilty Secret, Dark Secret, Embarrassing Secret, and so on.
  • Similar to the GURPS example; the BattleTech RPG A Time of War has the negative trait "Dark Secret". These can range from things that could harm the character socially up to something that could trigger an interstellar conflict. Should it be discovered the PC can expect to gain Enemy, negative Repuation and Bloodmarked traits.
  • The Old World of Darkness had a one point flaw called Dark Secret. That it's only worth one point tells a lot about the setting.
  • Fading Suns has the Dark Secret disadvantage, in three levels depending on the severity of the secret. It also has the Secret advantage, which (among other things) may mean you know someone else's Dark Secret.
  • Almost everyone in Warhammer 40,000 has their own dark secret, but the Dark Angels Space Marine Chapter really don't want anyone to know half their chapter joined the other side during the Horus Heresy. Ironically, it's implied in other fluff that not only are the Inquisition fully aware of the Fallen Dark Angels, but they don't really care too much. That means their self-appointed mission to keeping the Chapter "secret" a secret and the numerous atrocities they commit in its name are utterly pointless and simply alienating the rest of the Imperium.
  • In Shadowrun it is assumed that every Player Character has one of these (after all, sane people of good upbringings do not run the Shadows). The players can instead choose from a wide variety of Negative Qualities at character creation that decides exactly what kind of dark secret you harbor, and how much it burdens you day-to-day as well as the fallout if someone discovers it. The smallest dark secrets (1-5 karma) involves things like 'a MegaCorp has a file on you' or 'a big regret in your past that gives people blackmail material on you'; the big ones (20+ karma) involves things like 'secretly an undercover cop' or 'actually a Corporate Samurai hiding in the Shadows' which are practical death sentences if the wrong people (like your party) find out.

  • Bloodborne's DLC revolves around your quest to discover Byrgenwerth's worst atrocity, which they've long since buried and which has caused the creation of the Hunter's Nightmare. A fellow hunter named Simon (and appropriately called 'Seeker of Secrets') points you in the right direction after warning you that the Healing Church (a Byrgenwerth offshoot) will try to stop you. Note, the secret is not how all hunters will inevitably go Ax-Crazy and that all of the first few generations of hunters (and Healing Church clergy, for that matter) have succumbed to this fate- that's confirming what the main game already hinted. It's also not that the Church's early experiments turned patients into featureless blobby lumps- that's just a sideline and you'll only be attacked by two anonymous church hunters for peeking. The real secret, which you have to fight Lady Maria of the Astral Clocktower to reach and that will get you repeatedly invaded for discovering, lies in the third and final area: the Fishing Hamlet. The Hamlet had a mutually beneficial relationship with the Great One Kos. When Byrgenwerth found out, they sent some of their scholars and the first few hunters over to massacre/experiment on the inhabitants, and they either ended up killing Kos or violating her corpse (and may have killed her unborn child). For this, the survivors cursed all of Byrgenwerth's successors to fall to bloodlust and the Hunter's Nightmare. The unborn child exists in a strange limbo as the Orphan of Kos.
  • Sword of the Stars II: Lords of Winter reveals that the Liir have been harboring a dark secret: the Suul'ka are really Liir Elders who have refused to die and became Drunk with Power. The bit about the Liir killing all Suul'ka with a bio-engineered plague is complete bull.
  • The Dark Secret of Nathan Drake, the Badass Normal treasure-hunting descendant of Sir Francis Drake, is revealed in Uncharted 3: Drake's Deception: he was never an heir of Sir Francis, merely a ward of the state with a history obsession and a Changeling Fantasy.

And that someone calling themselves 'the Woodcutter' has found out said secret and has begun to blackmail him because of it.

  • Dragon Age:
    • Thedas is full of these. Every single organization, race, and country with high repute has at least one dark secret. Others don't even bother keeping their "darkness" secret.
    • After Awakening, the existence of both the talking, sapient Darkspawn known as the Disciples and their creator, the Architect, are kept a secret to the rest of Thedas by the Grey Wardens.
    • Dragon Age: Inquisition: The Seekers' initiation is outright horrifying: first they are lobotomized with a magical process called Tranquility. Then they have an emotional substitute injected into them by a spirit of emotion in the fade. That's right, they had the cure to Tranquility all along. Yet they kept it a secret from the Chantry, the templars, and the mages. This omission basically triggers the Mage-Templar war and the collapse of the Chantry.
  • This is the main drive of Final Fantasy XIV's Heavensward expansion: the heroes learn that Ishgard's 1000-year war with the dragons was actually caused by King Thordon I and his 12 Knights, who murdered a dragon desiring their power then stealing Nidhogg's eyes. The main expansion and the first three major patches afterwards are about revealing the truth and forcing both sides into peace.
  • All over the place in Dead In Vinland, including some real doozies. The Player Party tends to be... untrustworthy.
    • Eirik never warned his family of his suspicions about his true parentage: he's the bastard son of the old jarl, and the men who nearly killed his family and chased them into exile were trying to eliminate the heir's potential rival. Eirik's Guilt Complex kept him silent about this matter even after the fact. He also participated in a Viking raid in his youth, which he regrets.
    • Tomoe broke her own code of honor as a samurai. Her husband and children were killed by attackers, but rather than staying and fighting to the death to avenge them she fled for her life.
    • Knut was actually exiled from his homeland because he beat a man to death for looking at his wife Solveig, a fact he hasn't even told her. He also beats Solveig.
    • Yaghoub isn't actually a merchant — or at least that's not his primary occupation. He's a Hashhashin, and the new jarl hired him to kill Eirik. He also kidnapped Parvaneh several years ago, knowing that a cruel king wanted to take her as his bride and would likely murder her soon after. He's kept her in a Gilded Cage all this time, protecting her from the king's agents but also keeping her prisoner against her will.
    • Eustache WAS a monk... once. His father, a French nobleman, was assassinated, so Eustache left the monastery, became a swordsman, and vowed revenge.

He doesn't remember doing this and has no idea why he has lots of scars and people he knows keep dying mysteriously...
  • Mega Man X At first glance, Zero acts like a typical Anti-Hero who still does what is needed to set things right. However... As Mega Man X5 reveals as the story progresses, especially if you use Zero himself throughout the story, you'll discover that, not only was he the original source of the Maverick Virus, he also was, unbeknownst to Zero himself, created by Dr. Wily himself to be the next-generation rival to Mega Man X originally. Fortunately, or unfortunately, the Maverick Virus got passed to Sigma after Zero nearly brutally took down Sigma, only stopped after an intense stimulus renders Zero temporarily stunned so that Sigma cracks Zero's forehead jewel, knocking out the then-rampant Zero and thus begins the events that lead to the Mega Man X stories and beyond.
  • Starcraft II:
    • Tychus Findlay. The Dark Secret in question is his deal with Mengsk: he kills Kerrigan, he's free. As he says at the end of the Wings of Liberty chapter:
      "I made a Deal with the Devil, Jimmy..."
    • In the secret mission "Piercing The Shroud", it is discovered that the Dominion is behind the Zerg-Protoss Hybrids, which play a very important part in Zeratul's missions. Yep, that's right: it seems that the Dominion (with some dirty help) wants to bring The End Of The Universe As We Know It.
    • Mengsk's other dark secret is his role in the fall of Confederacy, namely that his hand was on the button that murdered eight billion humans and toppled their government, leaving him free to take over what was left. Given the magnitude of the crime, he's understandably kept it under tight wraps since becoming Emperor. Raynor's Raiders, naturally, have an opportunity to blow it wide open.
    • And a very large one for the Protoss: The majority of the Xel'naga never uplifted the Protoss, nor the Zerg, because (A) they have a strict Alien Non-Interference Clause, and (B) Amon murdered most of them and enslaved the sole survivor. Amon uplifted them specifically to watch them war against each other, and then merge them into abominations of his own making.
  • Vermintide II: When the whispering daemon in "Blood in the Darkness" taunts the characters, it reveals that every one of them has one:

      Nameless Voice: What's your blood-price for the elf? The zealot? The wizard? I know you've thought about it. How heavy would the purse have to be?
      Markus: Go annoy someone else.
    • Bardin: Bardin's mistakes on a mission left him gravely wounded by a Gutter Runner and unable to warn a Dwarf stronghold of a Skaven attack, and as a result many of his people were slaughtered including his son Mordin. He was punished by the other Dwarfs and too cowardly to take the Slayer oath, so he built an elaborate identity because "Holdseeker" sounds more comforting than "Exile".
      Nameless Voice: Ziflin Deeps. A word from you, and so many would still be alive. But you weren't there, were you?
      Bardin: [annoyed growl]
    • Sienna: Sienna has killed multiple people in her wild pyromania for the thrill of it. She burned a templar to death who was hunting a "witch", and later found that the templar was Properly Paranoid and the witch really was a dangerous Chaos-worshipping monster. She also burned the entire town down in the process of killing this templar.
      Nameless Voice: You do remember Rambler? He helped you harness your gifts, and you burned him alive for it.
      Sienna: It's the past, it's done.
    • Victor: Saltzpyre's faith in Sigmar is actually faltering significantly behind his fiery rhetoric. He doubts Sigmar is actually real and wonders if he can even do anything to avert the impending collapse of the Empire. Also, he tortured and burned an innocent girl in the past due to overzealousness on his part, and the guilt is consuming him.
      Nameless Voice: You didn't save that Skaggerdorf burghermeister's daughter, did you? She pleaded for mercy as you drove home the stake.
      Victor: [bitterly] Leave me alone!
    • Kerillian: Kerillian heard a prophecy that Ubersreik would play a part in Athel Loren's fall. Interpreting it as the people of Ubersreik attacking her home and arrogantly believing that she could avert the prophecy alone, Kerillian launched an ambush on an Imperial military convoy sent to reinforce the city, killing dozens of Imperial soldiers and weakening the city... just in time for the Skaven to launch their attack. Ubersreik fell and Athel Loren was the next target in the Skaven's crosshairs. Her ego caused a Self-Fulfilling Prophecy, she has got many innocent people killed and doomed her forest home, it's all her fault and she knows it. Kerillian feels that she could be very easily convinced to turn to darkness, and murder her human allies in their sleep.
      Nameless Voice: Count your kills all you like. Repay Ubersreik's slaughter a dozenfold, a hundredfold. It will change nothing.
  • Every rival in Yandere Simulator has one of these that the Villain Protagonist can find out and use to ruin the rival's reputation.

  • Ace Attorney has a number of these. Figuring out what they are is the whole point of the game.
    • The sequences with Psyche-Locks involve a person's secrets/lies being locked up with spiritual locks and chains when confronted with a statement or question the person refuses to answer and may go to great lengths to keep that secret hidden. The more locks that appear, the more desperately the person wants to hide their secret. Phoenix can see the locks due to the Magatama item he carries and presenting the right pieces of evidence when questioning the person gets them to "unlock" themselves and reveal the truth. While a typical Psyche-Lock is colored red and can easily be broken, there's two occasions where the locks are black and can't be broken by normal means. Phoenix first sees the black locks during Apollo Justice: Ace Attorney when he asks Kristoph Gavin why he killed Shadi Smith, Kristoph refuses to answer and 5 black Psyche-Locks appear, which Phoenix describes as cold and dark and probably cannot be unlocked. The black locks appear again in Phoenix Wright: Ace Attorney – Dual Destinies when Athena is accused of killing her own mother several years ago and the suppressed memory of the event causes her to throw up 5 black Psyche-Locks. Phoenix finds out from Pearl that the black locks mean that someone has a secret buried so deep within their hearts that they are not consciously aware of it and if the Magatama user tries to brute force the locks open (not approaching the topic gently in other words), the person's spirit can become broken beyond repair, and they are traumatized for life. Luckily, Phoenix gets past Athena's locks without any damage to her mental state.

  • Amanda from Daughter for Dessert is attracted to her own father and has been since she was very young.
  • Multiple characters in Double Homework have these:
    • The protagonist and Tamara are covering up their role in the Barbarossa incident, and just how much they knew what would happen beforehand.
    • Dr. Mosely has her secret identity as Zeta, the rogue scientist.
  • In Higurashi: When They Cry, there's Keiichi's habit of shooting kids with a BB gun, Rena's psychotic episode, Satoko's unwitting murder of her parents, the Sonozaki family's complete lack of a Dark Secret, despite all their posturing, and the fact that Rika is stuck in a "Groundhog Day" Loop.

    • Calgar is hiding the secret to Ultramarines' invincibility, and the mere possibility that someone may figure it out makes him panic.
    • True to the lore, the leaders of the Dark Angels chapter is paranoid about anyone learning about the Fallen, but Azrael takes it to ridiculous extremes by siccing Asmodai on two Dark Angels who innocently ask about the Fallen when Azrael mentions them in their presence (and they were recently inducted into the inner circle, too, which means they were cleared to learn about the Fallen in the first place).
  • Murder Drones: It's immediately made obvious that V not only doesn't have the same memory issues that N does about their pre-disassembly drone lives, but also has a far clearer picture about everything that's currently happening than most of the cast. The fifth episode ultimately has Uzi cut out the middleman and directly hack her brain (alongside N's) to figure out some of this information, by which point it's been all but stated that V refused to explain things due some of the associated memories being traumatic.
    N: She's hiding mystery stuff and being overdramatic about it!

    • Ozpin is only one of many reincarnations of the ancient hero Ozma with Oscar Pine being his latest life and both he and Salem used to be lovers in the ancient past before a falling out led to them becoming enemies.
    • After learning about their past, the heroes learn that Salem herself can't even be killed due to her immortality and that despite being the leader of the group fighting against her, Ozpin revealed that he doesn't even have a plan to deal with her.
    • Salem's latest Grimm, The Hound, has the ability to speak due to having a Silver-eyed Faunus as it's core.

  • In Doc Rat, Doc pops the question to Danielle before she learns he's already married.
  • Characters in Ménage à 3 and its spinoff Sticky Dilly Buns are mostly pretty open about sex, but there are things that even they prefer to keep quiet...
    • Amber doesn't want her parents to know about her past career as a porn star. How well she can keep this from them if her straight acting career takes off remains to be seen. She also obliged her younger sister Ruby to preserve this secret for several years, which has caused the very truthful Ruby a lot of stress.
    • Meanwhile, Ruby tries to keep anything faintly embarrassing or just slightly unconventional about herself, such as her brief (and quite creditable) adventure in male disguise, or her liking for yaoi, secret from Amber. Apparently, her self-image as the serious, respectable one in their relationship is vitally important to her, or she assumes for some reason that Amber would taunt her mercilessly given half a chance.
    • Tracy, who works as a webcam girl and who let herself almost be drawn into an orgy by her porn star friends at one point, doesn't want these facts known at the games company office where she's working as an intern. When Gary, who knows these secrets, turns up there for a job interview, Tracy's usual niceness slips a little as she persuades him not to say anything.
  • El Goonish Shive: Mrs. Kitsune is very much aware of the magical world. She is absolutely determined to not let Nanase know that she's in on it.

  • Amphibia: Marcy knew all along what the Calamity Box would do and stranded herself, Anne, and Sasha in Amphibia on purpose.
