Undead Author

"Jack Sparrow: It's the Pearl. Prisoner: The Black Pearl! I've heard stories. She's been preying on ships and settlements for near ten years. Never leaves any survivors. Jack Sparrow: No survivors? Then where do the stories come from, I wonder?"

- Pirates of the Caribbean: The Curse of the Black Pearl

This happens whenever a character relates a story or an urban legend they've heard about some monster or location which never leaves anyone alive. Ten to one, it'll directly affect them later.

This of course raises the question of where the legend came from, if nobody has ever lived to talk about it? Perhaps the author was undead. Or maybe the author was the monster. Or perhaps the telling permits the author to have seen the monster in action but not be a target (e.g. using the quote as an example, perhaps someone on a ship saw the Black Pearl attack a settlement).

Anime and Manga
"Yue: Of course, no one who has seen the Library has lived and returned to tell the tale... Ku Fei: ... Then how does Yue know about it, aru?"
 * Gets a Lampshade Hanging in Mahou Sensei Negima when Yue talked about the Deep Library after they fell into it during the Library Island Arc.


 * It appears in an episode of Pokémon when James, not wanting to reveal his true childhood, tells the cast a flashback story about how, as a child, he ran away from home with his canine pokemon "Growley", only to freeze to death in the snow while his pet howled mournfully at the moon. While most of the characters are moved to tears, Misty, playing the Only Sane Man, responds that he obviously didn't die since he's telling the story, at which point James quickly falls back on Easy Amnesia ("I'm so confused!") as his answer.
 * In Claymore, the lampshade is hung upside-down when Ophelia claims that she doesn't have a nickname like the rest of the Claymores because she doesn't leave any survivors when she fights.
 * Averted in Cowboy Bebop, where Pierrot le Fou leaves almost no-one alive from his attacks, although the ones that do survive to tell the tale are eventually all hunted down and killed anyway.
 * He's so little known that Spike has no idea who the hell is attacking him.

Film

 * Lampshaded in the first Pirates of the Caribbean movie, with regard to the Black Pearl. As it turns, though the Black Pearl and its crew are indeed dangerous, they leave plenty of survivors in their wake.
 * Schindler's List has an example similar to the one above, with one character arguing the Nazis can't really be killing everyone. The context, though, makes this tragic irony rather than comedic irony.
 * In The Princess Bride, it is stated that the Dread Pirate Roberts "never [leaves] captives alive." One wonders why anyone would ever surrender to him.
 * In the book it's made clear this only applies if they fight, if they just hand over the valuables they can go. This was the whole point of building the reputation in the first place; a technique used sometimes by Real Life pirates.
 * And nobody has ever survived the Fire Swamp though they somehow all know its dangers, including the R.O.U.S.es
 * Specifically averted by Natural Born Killers in which the title characters always leave alive one witness to tell the tale. (This turns into a plot point at one stage of the story.)
 * The Goonies specifically had someone mention this with the legend of One-Eyed Willy. The main character gives a Hand Wave and says he asked his dad the same thing; probably one person got away.
 * Averted in Inglourious Basterds; the titular Basterds always leave one Nazi Nat-zee alive to spread the word about them. But not before carving a Swastika onto their foreheads, so even if they don't tell the story, other people will know it.
 * The Alien vs. Predator movie has the pyramid filled with hieroglyphs which include the details on how the ancient civilization ended. One wonders who was around to add those details, since all of the humans were dead and the Predators apparently abandoned it for thousands of years.
 * Lampshaded in Kick-Ass, where Kick-Ass/David tells the people in the audience who figured he wouldn't die at one point because he's still narrating to stop being a bunch of smartasses and lists several films with Posthumous Narration.
 * Lampshaded in D.E.B.S., where the four DEBS members are preparing to spy on Lucy Diamond. Apparently nobody has ever fought her and lived to talk about it.

Folklore

 * Two mythological monsters, Medusa and the Basilisk, possessed magical auras that would kill anyone who looked at them (and, in some versions, anyone they looked at). Despite this they were often physically described in great detail in the legends. In the Medusa's case it could be argued that this was because looking at her reflection in a mirror wasn't lethal and someone could have seen only their reflection. But there is really no excuse for the Basilisk, who not only had a lethal reflection, but also breathed poison gas as a backup weapon (JK Rowling tweaked the Basilisk for the Harry Potter series so that indirect looks at it were nonlethal, but induced petrification).
 * It also helps in Harry Potter that they have a literal undead author in the case of Moaning Myrtle.
 * Scottish folklore says that anyone who hears the flowers of the Bluebell ringing will die immediately. Well, then who lived to tell about it?
 * Someone who was deaf?
 * This is an often-cited Fridge Logic issue with the old wives' tale that if you die in your dream, you'll die from the shock of it in your sleep and never wake up. If the people who die in their dreams never wake up, how does anybody know what they were dreaming about when they died?
 * Snopes.com has expressed bewilderment at people who send them that "My name is so-and-so, I am but three/Tonight my daddy murdered me" poem and ask if it's "real" or not.

Literature

 * Inverted in the Discworld book The Fifth Elephant: Carrot assures Gaspode that there have been no reports of wolves attacking humans unprovoked, and Gaspode reasons that this might be because no unprovoking human who did get attacked has ever returned to tell the tale.
 * And again in The Last Hero:
 * Similarly inverted in The Paths of the Perambulator, when Jon-Tom narrowly avoids being killed by . When he protests that there are no such things on his (our) world, Mudge half convinces him that there could be, if anyone who encounters one dies and is written off as the victim of a mundane hiking accident.
 * Edgar Allan Poe was usually good about averting Undead Author. He even did it with The Pit And The Pendulum, though he had to resort to a Deus Ex Machina.
 * He arguably did it literally with A Predicament, a Stylistic Suck-laden Self-Parody where the narrator mangles a fair number of literary references, gets herself decapitated and survives to lament her situation.
 * Some biblical traditions hold that Moses wrote the entire Torah or Pentateuch... which invokes this trope when you realize that this means he narrated his own death in Deuteronomy 34.
 * Usually waved off by claiming that either this part was written by Joshua, or Moses in a God made trance.
 * The wording of the location of Moses's grave indicates that it was written not contemporaneous to Moses's death, but long afterwards.
 * Ambrose Bierce's The Stranger plays the trope straight, with deep emphasis on undead. A troop of Union soldiers on an exploration quest through Arizona is approached by a mysterious man who narrates the story of four previous explorers, Ramon Gallegos, William Shaw, George W. Kent, and Berry Davis, who committed suicide while besieged by Apaches in a cave rather than dying of thirst. When a listener scorns and curses him for abandoning his comrades in their death, the stranger does only tell again they were four of them who died, and disappears. With uncanny calm, the troop's Captain acknowledges that years before there had been found and buried the bodies of four men, mutilated by the Indians, and the storyteller had been just whom he said he was, Berry Davis, who even if shot again "couldn't have made him any deader".
 * In The Wheel of Time, perpetually-reincarnated heroine Birgitte tells Mat the story of how one of her past incarnations fought her way into the Tower of Ghenjei, home of the Snakes and Foxes, to make them cure her wounded lover. Mat asks how she got out, and she tells him that she didn't; she and her lover both got killed and that incarnation ended there. Nevertheless, she's surprised he's never heard the story before and Thom recalls a distorted version of it later, which is par for the course for the way legends and myths work in the series.
 * It's explained that the story resulted from someone asking the denizens what happened to her.
 * In Surely You're Joking, Mr. Feynman, Richard Feynman mentions how he was outraged at an account taught in Sunday School that told of a girl's dying thoughts. How did they know what she thought?
 * Many of H.P. Lovecraft's stories, considering his preference for first person and high protagonist mortality rate. Though Call of Cthulhu at least justified the account of the encounter with Great Cthulhu in that some of the sailors who delayed him managed to live long enough to write it down.

Live Action Television
"The Doctor: Almost every species in the universe has an irrational fear of the dark, but they're wrong, because it's not irrational. It's Vashta Nerada."
 * Doctor Who uses the "mundane hiking accident" variant in "Silence in the Library" for maximum Paranoia Fuel. The Vashta Nerada exist on every planet; the reason we never hear about them is because they exist in dark and isolated places, and, well, you know how people go missing in the woods...

Music

 * The singer of Like A Boss is asked to describe an average day. Apparently an average day consists of chopping his balls off, crashing into the Sun and dying.
 * And turning into a jet, bombing the Russians, sucking his own dick, and eating chicken strips
 * Trouble on Dookie Island ends with the Villain Protagonists getting killed by the police.

Newspaper Comics

 * Parodied in this Nodwick strip.

Tabletop Games

 * The most popular origin story of the Skaven from Warhammer Fantasy Battle is called The Doom of Kavzar. The ending implies that everyone in Kavzar got eaten by rats. And even if the rats were smart enough to be regarded as proper Skaven, Skaven don't give a crud about the history of their kind, so it's not like they would have bothered to write it down.

Video Games

 * In Fire Emblem Shadow Dragon Marth decides to proceed on a quest deemed suicidal, noting that these rumors couldn't be entirely true because of this.
 * Brought up in Persona 3, when the heroes hear a ghost story about a deadly curse that befalls anyone who stays too late after school. They immediately realize that, if everyone it's ever happened to dies, as the story claims, then nobody would've ever found out about it. While there's a grain of truth to the idea that the school can become dangerous at night, the details of the story turn out to be an urban myth.
 * In Fallout 2, Harold the sort-of ghoul tells several stories about himself that end with 'Everybody died'. One of your chat options is 'How did you survive?' He always answers "Didn't! Got killed!"
 * In Monkey Island 2: LeChuck's Revenge, most of the events of the game are framed by Guybrush telling the story to Elaine, and at one point it appears that Guybrush has died, upon which Elaine remarks that he couldn't have died since he's right there relating it to her.
 * In Higurashi no Naku Koro ni Keiichi points out Oiishi's use of this trope when he tells a story about how the old demons of Hinamizawa demanded a mother feed herself to one of them in exchange for curing her son and when she ran away the demons (with the other villagers' help) caught and ate them both. Oiishi counters that a lot of old stories are like that.
 * Similar to the Monkey Island example above, addressed in Interactive Fiction game Spider and Web. Most of the game is framed by the captured spy PC telling the story to an interrogator. If the PC gets themselves killed, the interrogator will interrupt: "And then you died?", forcing the PC to backtrack.
 * In Prince of Persia: The Sands of Time, whenever the narrating Prince dies and the player decides to continue, he will say "That's not what happened" or a similar phrase.
 * Averted in Mass Effect where the last dozen Protheans who survived the Reaper genocide dedicated their lives to sabotage the Reaper plans for the next extermination cycle, giving their successors a fighting chance against the next Reaper invasion. Their efforts culminated in Vigil, a VI set up to tell the next sentient races about the Prothean's ultimate fate.

Web Comics
"Qubert: Oh no! You poor thing! *beat**beat* Wait."
 * Black Mage pointed it out early in 8-Bit Theater - if the Armor of Invincibility is said to be hidden in The Cave Of No Return, how can it be the Cave Of No Return? Somebody must've gotten out of there to spread the word that the Armor of Invincibility is there... (Let's not argue about the actual logic of this.)
 * In Gastrophobia, Phobia tells Gastro a story of an adventure that ends with her death, including a "Some say that on certain nights you can still hear my voice..." stinger.
 * Miya tells Dr. Qubert the tragic story of her, a young orphan girl, in issue 4: Talking To Myself. After an unkind and high-class vampire (probably one of the Cruors) hits her with a rock and tells her to get a job, her cat dies, then, exhausted and starving, she lays down on the ground, utters her final words ("God bless us, everyone"), and dies. Forever.

Western Animation
"Homer: [reading] Then I heard the sound that all Arctic explorers dread... the pitiless bark of the sea lion! [gasp] He'll be killed! Marge: Homer, he obviously got out alive if he wrote the article. Homer: Don't be so... [flips ahead] Oh, you're right."
 * Parodied in The Simpsons; Groundskeeper Willie tells a story about a miner's strike he was involved in which ended with a cave-in, and concludes his narrative "Nobody made it out alive - not even Willie."
 * And again where Grandpa recollects falling off the Murderhorn - "You'll die out there - just like I did. I fell 8,000 feet onto a pile of jagged rocks. 'Course folks were tougher in those days. I was jitterbuggin' that very night!"
 * Averted to Homer's surprise when reading a wilderness survival story.


 * The Adventures of Jimmy Neutron has Jimmy pointing out the Fridge Logic of an urban legend about a theme park, questioning how Nick could know the kids' final words if they were never heard from again.
 * Parodied in the Dilbert cartoon where a story of a co-worker killing an entire field hockey team and not leaving survivors was learned from reading it on her website.
