->''"We need its light\\
We need its heat\\
We need its energy\\
Without the sun, without a doubt\\
There'd be no you and me."''
-->-- '''Louis Singer''' and '''Hy Zarret''' (but [[CoveredUp more famously covered]] by '''Music/TheyMightBeGiants'''), "Why Does the Sun Shine"

The big brother of TotalEclipseOfThePlot, who crashes on the couch for [[TheThingThatWouldNotLeave a "few" days]].

This trope usually involves a BigBad's attempt to bring about either an eternal or extremely long night, [[ForTheEvulz for whatever reason]]. He could be trying to put out the sun,[[note]]it takes eight minutes for light from the sun to get to Earth[[/note]] block it, [[PartlyCloudyWithAChanceOfDeath or just find a metaphorical light switch]]. This is often the goal of a [[OurVampiresAreDifferent vampire]], for [[WeakenedByTheLight obvious reasons]]. The only requirement is that the darkness is supposed to last a ridiculous length of time, ranging from a hundred years to an eternity. It rarely does, though, thanks to those pesky [[BigDamnHeroes heroes]], who somehow manage to get past all of the looting, panic, and [[NightOfTheLivingMooks mooks]] to CueTheSun.

In RealLife, the amount of sunlight reaching the surface of the Earth can be dimmed to a surprising degree by [[ChekhovsVolcano dust thrown up by major volcanic eruptions]] (volcanic winter), [[ColonyDrop the asteroid strike at the end of the Cretaceous Period]] credited with killing off the dinosaurs (impact winter), and, in theory, [[AtomicHate the fallout of a nuclear war]] (nuclear winter).

Often the setting for a literal DarkestHour, and can result in widespread DarknessEqualsDeath. Don't be surprised if a DarkWorld happens to have a bad case of this.

Compare AlwaysNight, TheStarsAreGoingOut, TotalEclipseOfThePlot, PartlyCloudyWithAChanceOfDeath, SpringIsLate, EndlessWinter.

Contrast CueTheSun, EndlessDaytime.


[[folder:Anime and Manga]]
* The ''VideoGame/{{Darkstalkers}}'' OVA has Demitri inflicting this upon the Earth, driving humanity to desperation -- and setting up LightIsNotGood symbolism when BigBad Pyron drives the night away with his presence. Incidentally, if the sky's perpetually covered with clouds, [[FridgeLogic how can]] [[OurWerewolvesAreDifferent Jon Talbain]] turn into a wolfman if there's no moon?
** Talbain was born able to shift into his wolf-form-- no moon needed (though in the games he wanted to be rid of that form, and learned to control it when it became apparent it was a part of his blood). Ironically, some shots in the OVA show the clouds parting during night-time itself to show the moon.
* [[BigBad Hades]] in ''Manga/SaintSeiya'' wants to [[spoiler:bring the Greatest Eclipse which would darken the earth forever.]]
* In ''Anime/DigimonAdventure02'', [=MaloMyotismon=] tries to drown both the Digital World and Earth in darkness, even saying "You foolish [=DigiDestined=], watch closely now! Your world is being consumed by eternal night!"
* ''Manga/TheArmsPeddler'': a group of standard-weaknessed vampires created a forest where night never ends, bringing a village of humans along to keep themselves sustained. One of them turns against the others after they ate his human girlfriend (and turning some of their children into vampires who can survive in daylight).

[[folder:Card Games]]
* ''TabletopGame/MagicTheGathering''
** The dual plane of Lorwyn/Shadowmoor switches between the two settings every few decades. Lorwyn never gets darker than dusk, while Shadowmoor never quite sees dawn. It's also very unpleasant, since most of the creatures that were nice in Lorwyn are monstrous in Shadowmoor.
** The plane of Diraden (inspired in part by Shadowmoor) in ''Literature/ThePurifyingFire'' was put under a curse of eternal night by the evil vampire [[EvilOverlord Prince Velrav]].

[[folder:Comic Books]]
* This is the whole premise of DC's ''ComicBook/FinalNight'' [[CrisisCrossover crossover event]], when the Earth's superheroes are ''completely'' and ''totally'' unable to keep the Sun from being eaten, even with help from the villains. Only the HeroicSacrifice of [[GreenLantern Hal Jordan]] saves the day.
* ''ComicBook/JusticeSocietyOfAmerica''
** Obsidian attempts to spread darkness over the entire world in one arc.
** He does it again with the help of Mordru and Eclipso in the "Princes of Darkness" arc... and succeeds.
* ''In Blackest Night'', a famous ''Franchise/GreenLantern'' story by Creator/AlanMoore features a planet where this is, in fact the natural state of affairs orbiting a star that somehow produces heat but not light.
* After the Crime Syndicate defeated the Justice League and assembled every supervillain they could enlist in ''ComicBook/ForeverEvil'', Ultraman pushes the moon out of position to block the sun, casting the Earth into perpetual eclipse so it won't interfere with his powers (being the reverse-Superman, sunlight weakens him and kryptonite empowers him).
* ''ComicBook/JudgeDredd'': During the "Necropolis" arc, the Sisters of Death blacked out all light in Mega City One while the Dark Judges began to murder the whole population. The temperature soon dropped to 10 below freezing and the supply system quickly collapsed. Only several months later did Judge Dredd succeed in banishing the Sisters and restoring daylight.

[[folder:Fan Works]]
* ''Fanfic/{{Antipodes}}'' features both this and EndlessDaytime, with the sun and moon freezing in place.
* ''Fanfic/NightsFavoredChild'', a ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic, shows [[AlternateUniverseFic what would have happened]] if Nightmare Moon had succeeded in [[TheBadGuyWins defeating Celestia]]. Notably, the story manages to avert the WordOfGod about this trope's consequences (see Western Animation below), as Nightmare Moon created a ''second'' moon to take the sun's place during the former daylight hours, one that magically generates enough light and warmth to keep the world from freezing without disrupting the night.
* ''Franchise/SailorMoon'' fanfic ''Thy Kingdom Come'' has an alternate universe villain Calcite. In the vanilla setting, Calcite and his friends and family are [[MySpeciesDothProtestTooMuch genetically predisposed towards good in a species of demons]]. But in the universe, he goes above and beyond to [[SealedEvilInACan capture the dark goddess Metallica within himself]] to attain [[AGodAmI god-like powers]]. He is much smarter than other series villains and quickly dispatches the Sailor Senshi before launching an invasion of Earth from the Dark Kingdom. Actually, "invasion" is a bit of a misnomer. He make a grand announcement to all the world leaders, they defiantly vow to resist him to the last breath, and then he sets a magic dome of darkness over every landmass on the planet. Within a matter of months, there are massive ecological disruptions as plants cannot grow, animals can't eat plants that aren't there, and so forth. Calcite then imports nocturnal-growing plants from the Dark Kingdom and feeds them to the nations that surrender. Dark Kingdom flora and fauna quickly adapt and thrive and fill in the missing ecological niches. Too keep the planet from ''total'' extinction, the sun still shines on the oceans after about a hundred miles away from land to promote plankton growth and so on. After he is defeated and the sun is restored, there is ''another'' wave of extinctions as the Dark Kingdom-based life dies off, along with another big percentage of humanity who have adapted to it to survive.
* ''Fanfic/AnonymoosesMonsterGirlSaga'' has this eventually happen to the kingdom of Yaleria. Unusually, this is presented in a positive manner as it benefits the undead who take over.

[[folder:Films -- Animation]]
* When ''Disney/TheEmperorsNewGroove'' was in its conceptual stages and called ''The Kingdom of the Sun'', Yzma's original plan involved summoning an EldritchAbomination to snuff out the sun and plunge the kingdom into eternal darkness. She even got [[http://www.youtube.com/watch?v=374xW4zZbZA a great song]] about it.

[[folder:Films -- Live-Action]]
* In ''Film/TheMatrix'', this is done by the humans to stop the machines, since the machines are solar powered and it was assumed they'd run out of power if denied the sun. Instead, they won the war anyway then turned the humans into a new power source.
* The Strangers from ''Film/DarkCity'' die when exposed to sunlight, so they keep the title city in a constant state of night.
* ''Film/TheDayTheEarthFroze'' (based on ''Literature/TheKalevala'', seen on ''[[Series/MysteryScienceTheater3000 MST3K]]'') has the witch Louhi cause this by stealing the Sun, resulting in a neverending winter night.
* In the movie ''Film/{{Legend 1985}}'', the BigBad Lord of Darkness is attempting to bring this trope about by killing the world's unicorns (the source of the world's light.)
* In ''Film/AKnightsTale'', Will flirts with Jocelyn along these lines, saying if he could ask God for one thing, it would be to stop the moon, so the night would last longer and he could spend more time with her.
* The majority of John Carpenter's ''Film/{{The Thing|1982}}'' takes place at night. The exact timeline isn't entirely clear but most fans approximate the film to be set roughly over the course of a week. This is actually a justified example, since the story takes place in at the beginning of winter in Antarctica.
* Once things start getting weird in ''Film/GraveEncounters'', multiple days pass for the film crew trapped in the haunted asylum, without any break in the night's darkness.
* ''Film/{{Vampirella}}'': Vlad's [[EvilPlan big bad plan]] is to use a system of satellites to create a nuclear winter on Earth, allowing vampires to hunt humanity to extinction.

* In the backstory of the ''Literature/LoneWolf'' series, [[NamesToRunAwayFromReallyFast Agarash the Damned's]] reign of terror was called the "Age of Eternal Night". In the series proper, Agarash's lieutenant Deathlord Ixiataaga used his powers to maintain a permanent cloud cover over the city of Xaagon which prevented any sunlight from reaching it.

* In ''Literature/GulliversTravels'', the first punishment for cities rebelling against Laputa is to stop the island over the city, denying the people sunlight. If that doesn't help, they start dropping rocks down. The final stage is [[SquashedFlat landing the island on the city]]
* ''[[Literature/BlackJewels Heir to the Shadows]]'' sees [[MarySue Jaenelle]] create an ''illusion'' of this in order to force the government to let her stay with her guardian.
* In Creator/SimonRGreen's ''Literature/BlueMoonRising'', the title [[BadMoonRising evil moon]] also brings with it a side order of eternal night.
** The Literature/{{Nightside}}, setting for another Green series, hasn't seen a sunrise since prehistory. It's always three in the morning in the Nightside. Unlike most examples of this trope, the unending night hasn't done it any harm; in fact, the usual Night-That-Never-Ends plot is inverted when one novel's BigBad plots to call the Sun back to the sky, which would bring disaster.
* The ultimate goal of the vampire bats in ''[[Literature/{{Silverwing}} Sunwing]]'' is to free their god from imprisonment and bring about eternal night.
* ''Literature/TheNightLand'': Millions of years in the future, the sun has burned out and all of the other stars in the universe are dead as well. The last few million humans still alive stay warm by means of the "Earth Current", or geothermal heat.
* Garth Nix's ''Literature/TheSeventhTower'' series: unusually, done by the good guys in backstory to wipe out a [[LivingShadow race of evil shadows]]; without light, there are no shadows. The villains want to ''restore'' the sun, and the heroes have to stop them.
* In Creator/RobertAHeinlein's ''Literature/HaveSpaceSuitWillTravel'', the intergalactic security council decides to punish a race by sending the race's planet to a separate universe... without their sun. Earth [[spoiler:avoids this fate only by the hero's PatrickStewartSpeech and actions]].
* In ''Literature/TheCourtshipOfPrincessLeia'', an ex-Imperial warlord punishes a rebellious planet by employing an "Orbital Nightcloak", a system of satellites that not only keeps all sunlight from reaching the surface, but also blocks all signals they send to other planets asking for help. He's a jerk like that.
* Middle-earth stories:
** Sauron does a minor version of this in ''Literature/TheLordOfTheRings'', to depress his human enemies' morale, and because a lot of his armies consist of creatures such as orcs and trolls which can't go out in daylight or are seriously impaired by it. He uses toxic fumes from his volcanoes to just blot out the sky for days at a time.
** [[GodOfEvil Morgoth]] does this three times in ''Literature/TheSilmarillion'':
*** The first time he knocks down the Two Lamps originally set to illuminate Middle-earth with EndlessDaytime, which [[ColonyDrop alters the ''geography'']]. The [[FantasyPantheon Ainur]] are the only sapients existing then (This was before the Awakenings of Elves and Men), and they end up moving to the continent Aman. On Middle-earth, life only survives because the Ainu Yavanna puts some of it into hibernation until the much later creation of the Sun. [[note]]Creator/JRRTolkien, realizing this made Middle-earth uninhabitable for the Elves, Ents, and Dwarves who lived there during the darkness, planned to radically change the whole cosmology and prehistory to make the Sun much older, but never got beyond drafts.[[/note]]
*** Later, after the Awakening of the Elves, Morgoth and [[EldritchAbomination Ungoliant]] destroy the Two Trees which the Ainur had created to light Aman, and spread clouds of "Unlight" which hide even the stars. The effects probably wouldn't have been quite so bad if Morgorth hadn't previously sowed dissent among the High Elves, and/or hadn't [[spoiler: stolen the Silmarils, the only things that could have resuscitated the Trees.]] During the period of darkness following that, we have, in short order: the rebellion of the Noldor, Elves slaughtering each other in the first Kinslaying, the declaration of the Doom of the Noldor, Elves betraying each other left and right, and the deaths of countless more of them crossing the Grinding Ice (after which the Moon and Sun rise for the first time).
*** Morgoth responded to the creation of the Moon and Sun by covering his Hell-fortress in volcanic clouds of toxic fumes, and then started spreading the fumes southward to blot out the sunlight over Hithlum and Beleriand.
* In ''Literature/ASongOfIceAndFire'', a character tells about the [[ExactlyWhatItSaysOnTheTin Long Night]] back in the Age of Heroes about 8000 years ago, which lasted a generation when [[HumanoidAbomination The Others]] almost overran all of Westeros. And now, they're rising again...
** In "The World of Ice and Fire" it's mentioned that other cultures, such as the Rhoynar and the people of Yi Ti, have stories about a similar event.
* An old folk story, adapted as ''The Moon in Swampland'' by M.P. Robertson, reverses the trope to have the Moon vanish, but with a similar effect. The Moon visits a swamp out of curiosity about the world below, where she's quickly captured, chained up and thrown into a sealed well by the bogies. Once her light's gone, they completely rule the night; every sunset ushers in hours of horror for the miserable humans, until a hero returns the world to normal by finding and freeing her.
* Let's not forget the classic: ''Darkness'' by Creator/LordByron. Long story short, society collapses as all people panic and [[KillEmAll unsuccessfully]] try to save themselves. Biblical imagery is repeatedly introduced, but any related tropes are deconstructed, and the overall tone is one of cynicism.
* A Russian children's poem "Stolen Sun" by Korney Chukovsky narrates how the crocodile consumed the Sun and how the bear gave him a proper pummeling and forced him to release the star back into the sky. No, it doesn't make sense in context either, but it does take on the motifs of Slavic myths about a dragon stealing the Sun and imprisoning it for thirty-three years, cueing global night and cold.
* Creator/RobinJarvis' ''The Deptford Mice'': [[spoiler: Jupiter intends to put out the sun and cause eternal winter]].
* In Fritz Leiber's story "A Pail Of Air", Earth has frozen over after being pulled out of its orbit and cast into deep space.
* In ''Literature/{{The Sword of Shannara|Trilogy}}'' the [[BigBad Warlock Lord]] turns the Northland into this.
* ''Literature/{{Nightfall}}'' depicts a world with several suns, where normal night never falls and people are completely unaccustomed to darkness. Which is why, when every two thousand years total solar eclipse occurs, the ensuing darkness drives everybody insane and makes them burn down their cities in a desperate craving for light. How long the eclipse actually lasts is unknown, but apparently everybody decides that TheNightThatNeverEnds has fallen.
* In the Franchise/DoctorWhoExpandedUniverse novel ''Goth Opera'', vampires use a 'time freeze' to bring this about so they can go about their plan to vampirise humanity without having to worry about getting caught in the sunlight.
* In ''[[Literature/ZonesOfThought A Deepness in the Sky]]'', the planet central to the plot, Arachna, orbits a star that spends about thirty years around sol brightness and two hundred as a brown dwarf. The planet therefore has a few decades of normal day-night cycles and a couple centuries of endless night. Arachna's native inhabitants have adapted to hibernate during the dark periods and recolonize when the star relights.
* The ''Literature/StoriesOfNypre'' series features the Night Land, a place of eternal night. People who enter it tend to get mind controlled by the BigBad. Oh, and it's expanding.
* In ''Literature/TheStrain'', by Creator/GuillermoDelToro and Chuck Hogan, the goal of [[OurVampiresAreDifferent the Master]] is to do this (or, at least, something very much like it) via ''nuclear winter''. [[spoiler: He ''succeeds.'']]
* Lois Tilton's "Vampire Winter" revolves around a Nuclear Winter that allows a vampire to stay awake all the time and ravage survivors in several small towns.
* Literature/TheAdversaryCycle by F. Paul Wilson. At the start of ''Nightworld'' the sun rises five minutes too late. Literature/RepairmanJack can't understand why the scientists are so disturbed by this, but when portals to AnotherDimension open all over the world, spewing a horde of {{Eldritch Abomination}}s every night, the fact that every day the sun inexplicably rises later and sets earlier than the last [[TheEndOfTheWorldAsWeKnowIt becomes a reason for serious panic]].
* In ''Literature/{{Steelheart}}'', Newcago (Chicago) is locked in permanent darkness by the power of an Epic named Nightwielder.
* Victorian poet James Thomson wrote "[[https://en.wikisource.org/wiki/The_City_of_Dreadful_Night The City of Dreadful Night]]" as a metaphor for his depression, which often left him with prolonged insomnia during which he wandered the streets of London:
--->The City is of Night; perchance of Death
--->But certainly of Night; for never there
--->Can come the lucid morning's fragrant breath
--->After the dewy dawning's cold grey air:
* In ''Literature/TheShatteredKingdoms'', the sun (and moon, for that matter) haven't been seen in one particular country for time immemorial. The country's inhabitants are generally WeakenedByTheLight, and look (at least in the opinion of other people) rather like corpses.
* The Darkening in ''Literature/CompanionsCodex'': a powerful spell taught to Tsabrak Xorlarrin by Lolth herself, it plunges the sky over the entire Silver Marches into artificial darkness. It serves as intimidation tactic aswell as relieves the invading drow of their weakness to bright sunlight.
* In ''The Shattered World'', the FloatingContinent of Xoth is almost entirely shielded from the sun's rays by another, nameless fragment. This makes it an ideal shelter for the light-sensitive Cthons and their equally-averse cacodemon minions. [[spoiler: At least until the sequel, ''The Burning Realm'', in which Kan Konar destroys the shielding fragment's Runestone and it drifts sideways, exposing Xoth to the light.]]
* In N. K. Jemisin's ''Literature/TheFifthSeason'', the continent-shattering earthquake at the beginning of the book opens a volcanic rift continually pouring out enough ash to blot out the sun for thousands of years, kicking off an EndlessWinter.
* In the final book of ''Literature/TheKaneChronicles'', ''The Serpent's Shadow'', the chaos-snake Apophis basically swallows up the sun-god and if he had won, it would have been this. The official description for the final book even states, "He's b-a-a-ack! Despite their best efforts, Carter and Sadie Kane can't seem to keep Apophis, the chaos snake, down. Now Apophis is threatening to plunge the world into eternal darkness, and the Kanes are faced with the impossible task of having to destroy him once and for all."
* ''Literature/VillainsByNecessity'': Inverted. As the forces of light continue to spread unchecked through the world, it moves closer and closer to endless ''day.'' [[spoiler: By the end of the book, the world is sunny and bright in spite of it being eleven at night.]]

[[folder:Live-Action TV]]
* In ''Series/{{Angel}}'', The Beast blocked out the sun over Los Angeles, giving vampires and other demons a chance to come out and play without worrying about their curfew. After a few days or weeks of this, L.A. begins to look distinctly AfterTheEnd[[BuffySpeak ish]]. If not for [[NiceJobFixingItVillain Angelus]], the block would have spread all over the world.
* ''Series/GameOfThrones'': Winter is coming, and with it the days grow shorter. There is an in-universe FairyTale of a Long Night that lasted a generation the last time the White Walkers invaded Westeros. Stannis mentions it by name in "Second Sons" when discussing Melisandre's prophecies with Davos.
* In ''Series/TinMan,'' the ultimate goal of the WickedWitch is to lock the position of the BinarySuns behind the moon during a rare [[TotalEclipseOfThePlot double eclipse]], using a large {{Magitek}} device originally intended to slow the suns down for better crop growth.
* ''Series/DoctorWho'' has used this trope a couple of times:
** The Doctor, Martha, and Jack travel to the end of the universe in [[Recap/DoctorWhoS29E11Utopia "Utopia"]]. All the stars have burned out by then.
** The night caused by the Daleks' theft of Earth in [[Recap/DoctorWhoS30E12TheStolenEarth "The Stolen Earth"]]. The theme is even called "The Dark And Endless Dalek Night". Everyone not freezing is explained as the Daleks using an "atmospheric shell".
* Every planetary surface visited in the original ''Series/{{Battlestar Galactica|1978}}'' was cloaked in night for at least the first 14 episodes.
* ''Series/TheTwilightZone1959'':
** "[[Recap/TheTwilightZoneS5E146IAmTheNightColorMeBlack I Am the Night -- Color Me Black]]" has darkness enveloping regions of the world where hatred reigns.
** The CruelTwistEnding to "[[Recap/TheTwilightZoneS3E75TheMidnightSun The Midnight Sun]]" was that the young woman who'd dreamed of a broiling EndlessDaytime woke up into a freezing world headed for TheNightThatNeverEnds.
* Played with in the ''Series/{{Sanctuary}}'' episode "Carentan", where a localised time bubble causes time to pass at an accelerated rate for the inhabitants of a french town. Because of this, [[YearInsideHourOutside six years pass for every day]] outside of the bubble and the nights last for over ''3 years''. Due to the lack of sunlight during this period, the temperature drops to near-freezing and one of the inhabitants explains that many people do not survive.
* One episode of ''Series/StarTrekEnterprise'' took place on a rogue planet (see RealLife below). Unlike many examples, it was actually a fairly nice place, with a thriving ecosystem sustained by a very active geology. The hunters that they met on the planet mentioned that there were higher primates, implying the planet might eventually produce a civilization.
* In the US, most daytime soap operas appear to take place in eternal night. No sets ever have windows visible, and exterior doors always open to darkness. Rare outdoor scenes are shot with a blue filter for an ambiguous day-for-night look. The characters don't acknowledge this, and generally avoid mentioning the passage of time clearly.
* Simmons spent the time between seasons two and three of ''Series/AgentsOfSHIELD'' trapped on a world where the nights last for years and the days only last a few hours.

* Music/JonathanCoulton's "[[http://www.youtube.com/watch?v=G7YMZB6ds10 Always The Moon]]".
-->''Remember when there was a you and me?\\
When there was such a thing as gravity?\\
And the tides came in and the tides went out again\\
But the water got too high\\
And the sun began to die\\
And I tried to make you stay\\
But the world pulled you away\\
And now there are darker longer colder nights\\
And the sun has gone for good and so here we are''
* Music/TheKovenant's (formerly Covenant) debut album ''In Times Before the Light'' had this as a recurring theme in many of its songs, with lyrics referring to the "forevernight". They're from Norway, which might explain a few things.
* Music/TheCatEmpire has a song titled "The Night That Never Ends".
-->''As long as I am living\\
I never forget\\
That the sun is never rising\\
And it never set.''
* Music/{{Opeth}}'s song, Blackwater Park, features the closing line of both the song, and of the album: "The sun sets forever over Blackwater Park."
* Despite the title, Iron Maiden's Total Eclipse appears to actually be about this.
* Invoked in Music/MindInABox's cyberpunk-industrial music, which takes place in a future dystopia controlled by a secretive government agency. [[SequelSong As the song continuity progresses]], daylight is mentioned less and less, and the nights seem to grow longer. From the 3rd album onward, the cover art all depicts the protagonist at night. From "World of Promises":
-->''What I would do to have it back; a sky above that isn't black''

[[folder:Myths and Religion]]
* Literature/TheBible
** One of the ten plagues God punishes Egypt with in Exodus is darkness.
** Hell has a literal example of this trope.
* Where Literature/TheBible mentions [[TotalEclipseOfThePlot an anomalous eclipse]] following the crucifixion, ''Literature/TheBookOfMormon'' goes it one better and drops the American continents into three days of darkness ([[{{Foreshadowing}} as was previously prophesied]] by [[HeelFaceTurn Samuel the Lamanite]]).

[[folder:Puppet Shows]]
* ''Series/{{Dinosaurs}}'' ended with Earl accidentally starting the ice age that will kill the dinosaurs by blanketing the Earth in a cloud cover.

[[folder:Tabletop Games]]
* ''TabletopGame/VampireTheMasquerade''
** The "Crucible of God" Gehenna scenario features [[spoiler:the Antediluvian/ancestor of the Clan Lasombra blanketing the Earth in darkness for three weeks while it consumes its childer/descendants. No explanation is given as to how or why the darkness abates]].
** During The Week of Nightmares, Kuei-Jin elders created a supernatural storm to shield them from the sun to battle Ravana, the Antediluvian ancestor of the Clan Ravnos -- who was practically a vampire-god at this point. Then the Technocracy bombed them all, killing everyone who joined the battle; werewolves, Kuei-Jin and their ''own'' Agents. After storm dissipated, they scorched Ravana with orbital mirrors, a [[FantasticNuke spirit nuke]] and then some more end-world scenario weapons. The battle damaged the reality so much that it started the events that nearly ended the world. Perhaps letting the night never end was the better idea in the long run?
** This is also one of the long-term goals of Clan Giovanni -- tear down the Shroud that separates the world of the dead from the world of the living, thus creating an endless twilight kingdom where flesh and ephemera are one.
* ''TabletopGame/DungeonsAndDragons''
** One of the several planar gateways accessible in the 1st Edition ''AD&D'' module ''Queen of the Demonweb Pits'' leads to a world without a sun, where undead abound and vegetation must be sustained by magic.
** One artifact and a trio of adventures feature mind flayers trying to put out the sun. (In the second edition, mind flayers had great darkvision, could ''only'' see in darkvision, and regular light rendered them nearly blind.) A third edition book mentions that illithids hate and fear sunlight, and some of the more... ''unstable'' elder brains are deliberately working on plans to knock out the sun.
** While the Hollow World of TabletopGame/{{Mystara}} usually experiences EndlessDaytime, the disruptions brought on by the Wrath of the Immortals causes the planetary interior's central sun to go dark for a week. Most inhabitants thought that the world was coming to an end.
** This is the sign for the Elder Evil (from the book of the same name) Father Llymic, who becomes slowed (and eventually frozen over) when the sun is shining. In the final battle with the monster, the sun has completely gone out, allowing him to burst free of his icy prison and try to wreak havoc over the entire world.
* In Palladium's game ''TabletopGame/{{Nightbane}}'', the Day of Darkness -- 24 full hours of unnatural darkness (no stars, just a solid sheet of darkness across the sky) -- heralded the weakening of the barrier between our world and the Nightlands, allowing the Nightlords and their minions easy access to our world.
* Near the end of ''TabletopGame/{{Exalted}}'''s "Return of the Scarlet Empress", the Ebon Dragon causes an eternal night by [[spoiler:assassinating the Unconquered Sun]]. [[spoiler:Unusually, this backfires on the villain by distributing the Unconquered Sun's nigh-infinite power directly to the Exalted themselves.]]
* Night Lords from ''TabletopGame/Warhammer40000'' reportedly use this as part of "scare everyone to death before fighting even starts" shtick.
** It goes much deeper than that: Nostramo, the homeworld of the Night Lords was a world of perpetual darkness as a result of EXTREME amounts of pollution turning the sky black. In fact, one of the reasons for Nostramo's eventual rebellion was that when the Emperor arrived, he showed the Nostramans that there was light in the galaxy they would never get to see.
* ''TabletopGame/{{Warhammer}}'':
** One of the realms of [[TheLostWoods the forest of Athel Loren]], Modryn the Night Glens, is shrouded in eternal night, and the forest spirits and elves that live there are known to practice dark magic prohibited in the rest of the forest. It used to have a regular day-night cycle in the distant past, but became shrouded in darkness after the dark elf queen Morathi poisoned the soul of Ariel, the queen of Athel Loren, which among other things cast most of Athel Loren into darkness. Ariel eventually recovered, but night never lifted again from Modryn.
** Kholek Sun-Eater, one of the oldest Dragon-Ogre Shaggoths, is so named because his approach is heralded by storm clouds that precede and follow him. Whatever it is the dragon-ogres did so the Chaos gods would give them immortality at the beginning of the world, Kholek's deed was so horrible the sun refuses to see him, hence the clouds.

[[folder:Video Games]]
* In ''VideoGame/TheLegendOfZeldaTheWindWaker,'' Ganondorf casts a curse onto the Great Sea that [[http://zelda.wikia.com/wiki/Endless_Night prevents dawn from ever coming]]. Fortunately, this does Link more good than bad, as it ensures that Link will [[TakeYourTime always get Nayru's Pearl first]] due to the pirates taking time off at Windfall Island until morning; the curse is lifted once the Pearl is obtained. This same curse is also used in a more-localized fashion in the Forsaken Fortress, Ganondorf's base of operations. [[spoiler:When Ganondorf abandons the joint to go after Zelda, however, the curse is lifted there, as well.]]
* ''[[VideoGame/{{Touhou}} Imperishable Night]]'' sees the fugitive Lunarians in Gensokyo using powerful magic to seal the land from their home world, with a false moon placed in the artifical sky created as part of the spell. This causes lots of problems for humans and youkai alike, which in turn requires the heroines to help solve the problem.
** Subverted big time; The Night That Never Ends is ''[[WhatTheHellHero caused by your heroines]]'' to buy time. The false moon only appears at night, and if you fail to reach the source of the problem and fix it before the supposed time for dawn, [[NonStandardGameOver the game ends]]. Also, Keine Kamishirasawa (who defends the humans) and either one of Reimu Hakurei (who enforces law) or Marisa Kirisame (who is pissed off with your unnatural magic) will fight you to stop your heroines' madman scheme. LetsYouAndHimFight, definitely. [[AllThereInTheManual Supplemental material]] even indicates that most people in the land were completely unaware of the true threat and just assume the heroines actually solved the problem of the unending night.
** In fact, during the True Final Battle, once you defeat [[BigBad Kaguya]], she uses her power over "eternity" to tear apart your spell causing the imperishable night. Every time you die to a section of her final spell card, the time advances 30 minutes. If it reaches 5:00 during that time, the sun rises and the game ends. That doesn't cause a bad end, but losing all your lives during her stage will speed time all the way to 5:00 in one go and triggers the bad end, presumably due to her power. CueTheSun is subverted big-time here.
** Let's not forget the original Windows Touhou game, ''Embodiment of Scarlet Devil'', where BigBad Remilia Scarlet's scheme was to block out the sun with a thick red mist, just so she could go outside whenever she wanted (she's a vampire).
* In ''[[VideoGame/OsuTatakaeOuendan Ouendan 2]]'', the sun is growing cold and it's up to the Ouendan team and the entire population of the earth to cheer up a CombinedEnergyAttack big enough to restart it.
* Subverted in ''VideoGame/AmbridgeMansion''. The titular haunted mansion is located inside of its own world in which there is nothing at all outside of the house, only infinite blackness. There is no day or night, but the constant blackness makes it appear to be this trope.
* In ''VideoGame/PokemonMysteryDungeonExplorers of Time and Darkness'', the BadFuture was stuck in an eternal night because time had stopped.
* This has already happened in ''[[VideoGame/NintendoWars Advance Wars: Days of Ruin]]'': the meteorite impact kicked up a ton of dust which blotted out the sun.
* VideoGame/MasterOfMagic has a spell that does this. Yes, you can cast it. It's not as dramatic as it sounds though...
* ''Franchise/FinalFantasy'':
** In ''VideoGame/FinalFantasyIII'', Xande sinks most of the world into perpetual darkness and suspended animation because he does not wish to die after being [[BlessedWithSuck blessed with mortality]].
** In ''VideoGame/FinalFantasyThe4HeroesOfLight'', the second half of the game gives the world a red-and-black sky and the "night" music becomes permanent while on foot [[spoiler:thanks to the time-breaking flood of darkness you unleashed from Rolan's soul]].
** The Starscourge in ''VideoGame/FinalFantasyXV''. [[spoiler:And how; Daemons dying causes particles that absorb light to enter the atmosphere. The final chapter is set in a time where the night has lasted for ten years leading to the entire planet to be infested by Daemons leading to the near extinction of all life.]]
* Partly used in ''VideoGame/{{Okami}}'' [[spoiler:during the 'Day of Darkness', when the monsters get stronger]]. Amaterasu being the [[PhysicalGod sun]], may also have something to do with it.
* In ''VideoGame/QuestForGloryIV'', the vampire {{Big Bad}}s want to release [[EldritchAbomination Avoozl the Dark One]] in order to permanently cloak the world in the [[TitleDrop eponymous]] [[DepartmentOfRedundancyDepartment Shadows of Darkness]].
* The Crows in ''VideoGame/BillyHatcherAndTheGiantEgg'' have already succeeded in bringing eternal night to Morning Land. Billy's job is to bring the day back.
* A neverending winter night is the setting of ''VideoGame/ArxFatalis''. Luckily, sun was slowly dimming for five years, giving the population enough time to move underground. In the end, it's revealed that [[spoiler: sun is obscured by a giant space dust cloud and is barely visible even out of the atmosphere]].
* In ''VideoGame/NinetyNineNights'', the King of Ninety-Nine Nights is so named because during his last reign he caused darkness to fall for ninety-nine straight days.
* ''VideoGame/TheLegendOfSpyro: The Eternal Night''. It's right there in the title.
* In ''VideoGame/DarkSouls'', the First Flame that originally brought forth life is slowly dying, and sunlight is dying with it. There are already regions of the world that are covered in permanent darkness [[spoiler:such as Anor Londo, which only looks sunlit thanks to an illusion.]] While the ostensible goal of the Chosen Undead is to rekindle the First Flame, [[spoiler:the Primordial Serpent Darkstalker Kaathe]] claims that The Night That Never Ends [[DarkIsNotEvil won't necessarily be a bad thing for everyone in the long run.]]
* In ''VideoGame/{{Bloodborne}}'', Yharnam is a land without sunlight, lit only by the moon. [[spoiler: This is justified however, as the Hunter is trapped inside a dream. And the Moon existed as a [[EldritchAbomination presence]]. Should they free themselves from the dream, the morning sun would be seen again. However, if the Hunter chooses to free [[DeathSeeker Gehrman]] by killing him or become a [[EldritchAbomination Great One]] by defeating [[TrueFinalBoss Moon Presence]], the Hunter will never see the sun again.]]
* The ''Dawnguard'' DLC for ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' has a [[BigBad Vampire Lord]] seeking to blot out the sun through the use an Elder Scroll. You eventually gain the tools to do this yourself, [[spoiler:and learn it isn't quite as permanent as advertised, though easy enough to repeat on a daily basis]]. In addition to the vampire hunters opposing the Big Bad's scheme, he is also [[EvenEvilHasStandards opposed by other vampires]], although at least one does so [[PragmaticVillainy not so much due to any moral or ethical concerns]] as that she judges the end result of the scheme to be less 'eternal vampiric reign' and more 'mortals [[NeutralNoLonger get ''really'' pissed off]] and focus on killing off every vampire they can find until day returns'.
* Happens ever year in ''VideoGame/CityOfHeroes'', during the annual "Halloween Event", in which for two weeks in late October and early November the game's normal day/night cycle is replaced by endless nighttime.
* The ''VideoGame/StarCraft'' world Shakuras was shrouded in perpetual twilight for a considerable length of time. There were no plants, but plenty of fossils. The world lightened up after a significant plot event, but the ExpandedUniverse novels tell us the world is still fairly dark.
* The Puff Puff Machine in ''VideoGame/PaperMario64'' produces clouds that blot out the sun over Flower Fields, causing the area to experience The Overcast That Never Ends.
* In ''VideoGame/TalesOfXillia'', Fenmont is a localized and benign version of the trope. The city is situated within a spirit clime that creates an unending night. This is apparently just normal for the city.
* The ''VideoGame/TokyoXtremeRacer'' series features a non-villainous example of this due to the attempt to integrate the system's clock into the game. There is an InUniverseGameClock that matches up to the system clock, and is used for certain events, such as Wanderer opponents that only appear at certain times. However, the game is always set at night to reflect the nature of street racing as a nighttime activity; even if there's broad daylight outside your room and your system clock is set correctly, you will never see a single second of daylight in-game.
** Somewhat subverted in ''Import Tuner Challenge'' where you can select the Daybreak option.
* Tokyo in ''VideoGame/ShinMegamiTenseiIV'' has been living in one for [[spoiler:''twenty-five years'', due to the existence of a layer of bedrock that was set up by Masakado to protect Tokyo from a nuclear strike that would've otherwise obliterated the entire metropolis. There are people living down there who have never seen the sun. The lack of sunlight means that growing agriculture, though not impossible, is very, very difficult. To make it worse, the entire damn city is encapsulated in a bubble of slowed time. Outside it's been more than fifteen centuries. The Neutral ending has Masakado returning to lift the bedrock barrier, [[FirstTimeInTheSun allowing Tokyo to finally be granted sunlight once again]].]]
* The plot of ''Dark Vengeance'' revolves around a perpetual solar eclipse due to a BlackMagic spell, cast by the Dark Elves in revenge for their previous defeat by the High Council.
* In ''VideoGame/{{Faria}}'', the endgame has the EvilSorcerer magically blocking the sun's light from reaching Faria, whose inhabitants are freezing.
* The Mandeha Rakshasas of Lanka in ''VideoGame/{{Dominions}}'' have the sole goal of devouring the sun and plunging the world into darkness and are themselves surrounded by darkness as they frighten away the rays of the Sun.
** There's also the global Death enchantment Utterdark, which begins a perpetual night and screws over anyone without the ability to see in the dark and most of the provinces.
* [[BigBad Babylon]] does this is ''VideoGame/PocketBomberman''.
* ''VideoGame/GoldenSunDarkDawn'': Luna Tower is triggered in part by the protagonists (who'd been told not to) and by Ryu Jou (who had no choice in the matter). It ends up creating an artificial eclipse that casts a massive shadow over three or four countries that lasts until it absorbs enough sunlight. Unfortunately for everyone duped into starting it, it also caused [[DarkIsEvil things that live in the shadows]] to come out and start attacking people left and right. [[spoiler:The eclipse is finally stopped by using a magitek laser to fill up the tower's capacitators almost instantly.]]
* ''VideoGame/WarcraftIII'': The Moonstone is a Night Elf item that causes an eclipse, giving thirty seconds of nighttime (they're the only faction with spells that only work at night).

[[folder:Web Comics]]
* ''Webcomic/AuroraDanseMacabre'' is set in The Night That Never Ends.
* In ''Webcomic/TwoMoons'', the sun hasn't risen in 500 years, and [[CrapsackWorld life sucks.]] Humanity is kept alive, at least in one little city, entirely through genetically engineered food grown in unregulated for-profit labs. [[spoiler:Much later the sun does rise, and it apparently won't set for another 500 years, which will probably make life suck almost as much. The cause is never explained, but the planet's orbit and rotation have likely been whacked by asteroids.]]
* ''Webcomic/{{MYth}}: A Promise'' is set in an endless night because Cronus [[spoiler:kidnapped Eos to]] avoid Helios of rising the sun to keep the eternal darkness that he controlled. To avoid it, Selene is being in the sky for who knows how much time. [[spoiler:Luckily Eos was rescued and [[CueTheSun the sun cue]] before she got exhausted.]]

[[folder:Web Original]]
* The dark future in ''Literature/SpesPhthisica'': "a carmine ember that could once have been a sun burns coldly in the sky, giving scarcely any light or warmth."
* ''Terramirum'' starts with the sun imploding and the moon getting blown away, and works from there.
* ''WebVideo/EverymanHybrid'': In the non-canon video "Welcome to the ARK", Vinnie mentions that the sun has not been out in three days, and the video seems to show [[PerpetualStorm a storm raging outside.]]
* Speaking of the Franchise/TheSlenderManMythos, WebVideo/StanFrederick implies that a "Month of Night" occurred in New York before the series began.

[[folder:Western Animation]]
* ''Franchise/MyLittlePony'': The TropeNamer.
** Causing neverending night was the plan of Tirek in the very first ''My Little Pony'' animated adaption, a television special from 1984. Said bad guy, a demonic-looking centaur, quotes the trope name word for word.[[note]]Tirek reappeared in the finale of Season 4 of Friendship is Magic with a different goal.[[/note]]
** This is also the plot of the villain in the pilot episode of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' (a clear shout out to the 1984 special).
-->'''[[MadGod Nightmare]] [[FallenAngel Moon]]:''' Remember this day, little ponies, for it was your last. From this moment forth, [[PunctuatedForEmphasis THE NIGHT. WILL LAST.]] '''[[PunctuatedForEmphasis FOREVER!]]'''
** Because of [[PaintingTheFrostOnWindows the hands-on nature]] of... well, nature in ''Friendship is Magic'', some fans have grossly underestimated the threat posed by this scheme. WordOfGod has made clear, however, that this ''would'' cause [[TheEndOfTheWorldAsWeKnowIt the death of every living thing in Equestria]], by starvation if nothing else. It remains unclear whether Nightmare Moon herself was aware of this; preventing the sun from ever rising again may have been an attempt to force the ponies to appreciate the night ([[GreenEyedMonster and, by extension, her]]), or perhaps her bitterness at their [[DarkIsNotEvil misguided fear]] of [[TheSacredDarkness the night]] was such that her ultimate goal was to [[OmnicidalManiac exterminate them all]] (and maybe even [[SuicidalCosmicTemperTantrum herself along with them]]). [[Recap/MyLittlePonyFriendshipIsMagicS5E26TheCutieRemarkPart2 The season 5 finale]], however, [[GodDoesNotOwnThisWorld may have refuted this]] by having the BadFuture where she ruled [[NoEndorHolocaust show no signs of such apocalypse]] and actually look the least terrible of all the {{Alternate Timeline}}s visited.
*** The [[PeripheryDemographic fandom]] has taken this to new extremes of FridgeHorror. The ''Pony Psychology'' series has an entire chapter of WhatTheHellHero dedicated to Luna confronting Celestia over this, and Celestia painting the horror for her. In addition, several webcomics portray in gruesome detail just what a slow, agonizing death eternal night would be.
* ''WesternAnimation/ThePowerpuffGirls'', "Boogie Frights": the Boogie Man blocks the sun with a giant mirror ball so that monsters can stay outside forever. Even worse, they turn Townsville into a "nightmare nightclub", causing enough racket to keep the whole town awake.
* ''WesternAnimation/TheSimpsons'' two-part season cliffhanger ''Who Shot Mr Burns?'' had Mr Burns funding the construction of a sun-blocking device in order to force increased energy consumption by the town... just one of the many reasons people had to shoot him.
* Happens in ''WesternAnimation/RockADoodle''... sort of?
** Not exactly night, but the sun does go into hiding, and the weather is perpetually gray, rainy and miserable, resulting in dangerous flooding and other nastiness.
* Thanks to ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 TMNT: Fast Forward]]'' BigBad Sh'Okanabo and his progeny's [[WeaksauceWeakness weaksauce]] aversion to Earth's sun, part of his ultimate plan for world domination involved preventing the sun from reaching Earth via a series of satellites. It worked, too...for a few minutes.
* Samhain attempts to bring this about (along with eternal Halloween) in an episode of ''WesternAnimation/TheRealGhostbusters''.
* ''WesternAnimation/{{Ben 10}}'', Ghostfreak (to whom sunlight is fatal) tries covering the sunlit side of the earth with a shell of radioactive material in one episode, so he can rule it as his domain. (The fact that this will mutate the entire population of the Earth is an unfortunate side effect.)
* In ''WesternAnimation/YinYangYo'', this was the goal of Carl the Evil Cockroach Wizard. As it turned out, this was also the Night Master's intentions so that he could be all powerful. Carl got upset over him copying his idea.
* In ''WesternAnimation/JackieChanAdventures'', the combined power of Tarakudo's nine generals could summon enough Shadowkhan to shroud the earth in darkness. [[FridgeLogic Why they didn't do this before they were trapped in masks isn't explained]].
* In ''WesternAnimation/BarbieStarLightAdventure'', the stars going out prompts Barbie's search to find out why before the entire universe goes dark.

[[folder:Real Life]]
* A scientific journal detailed a DeathWorld simulation where they took a standard climate simulation model, shut off all solar input and saw what happened. It took less than a week for the continents to reach 270 K (i.e., freeze over); the equatorial oceans lasted a few weeks longer because of their large heat capacity.
* Places in the far north or far south such as Longyearbyen, Svalbard or Amundsen-Scott South Pole Station have a polar night that lasts for up to four months, bracketed on either side by one month of polar twilight.
* One of these probably occurred after the asteroid impact that killed off the dinosaurs. Dust thrown into the upper atmosphere partially obscured the sun for years (volcanoes can do a lesser version of this). While it wouldn't have actually been dark as night all the time, it would have been enough to kill off many plants (the things which support the entire food web) and reduce ocean temperatures (many marine organisms are very sensitive to temperature changes).
* The Great Smoke of London in December 1952 would probably be the closest example in human history. The light-blocker was smoke from fireplaces and factories, with smog from cars and buses, which was not unusual. However, add cold weather, an anti-cyclone over London, and a lack of winds, and Londoners got a smoke denser than usual, with visibility only being a meter, and that was during the day. Out of all mechanized transport, only the London Underground operated anywhere near properly -- buses had to have people in front holding torches. Concerts and movies had to be cancelled, because of the smog seeping indoors. Worse, it turned out to be a worse environmental disaster than originally thought. Estimates vary but between 4,000 to 12,000 people died during the week of smog.
* A planet that is tidally locked to its sun would have EndlessDaytime on the side facing the sun and The Night That Never Ends on the side facing away. It used to be thought that Mercury was like this, but [[ScienceMarchesOn that turned out not to be the case]].
* In the polar regions of our moon there are a series of valleys knows as "The Vales of Eternal Night" where due to the low position of the sun in the sky and the surrounding mountains are believed not to have seen any daylight for over a billion years. They are actually seriously considered as a location for a permanent moon base since there is evidence that there may be water ice from comets still there and the same geography that keeps them in perpetual darkness would also block radiation from solar storms. Power would be provided by putting solar panel farms on the nearby [[EndlessDaytime "Peaks of Eternal Light"]]
** Those aren't confined to the moon. The Norwegian village of Rjukan used to be entirely in darkness from September to March, until a large mirror was built on a nearby hillside.
* Some Roman Catholics believe in a prediction of "Three Days of Darkness" in which the only light will come from blessed beeswax candles. St. Hildegarde of Bingen and Padre Pio are among many who have predicted this.
* The three hours of darkness that Literature/TheBible attributes to the crucifixion of Christ was also recorded by pagans and referred to as "The Great Eclipse."
* The small Italian town of Viganella is situated at the bottom of a very steep Alpine valley, where the mountains completely block out the sun for 83 days between November and February. The residents finally got fed up in 2006 and built a computer-aimed 8-by-5 metre steel mirror array to reflect sunlight down into the village.
* Rogue planets, thought to have been flung out of their solar systems by gravitational effects from passing planets or stars, drift in the emptiness between stars, with no sun to illuminate them.
* This will happen to the Earth when our Sun eventually burns itself out. And given [[TimeAbyss enough time]], it will happen right across the universe, as very slowly over aeons, all TheStarsAreGoingOut...

-->'''[[WesternAnimation/ThePowerpuffGirls Narrator]]:''' SoOnceAgainTheDayIsSaved... [[DontExplainTheJoke Get it?]] The ''day'' was ''saved''? Because it was going to be ''eternal night''! They saved ''the day'' -- literally...
