Written by [[http://www.fimfiction.net/user/Jordan179 Jordan179]], this chronicles the return of Nightmare Moon in the Season 1 two-part opener, from Nightmare Moon's own point of view. Available [[http://www.fimfiction.net/story/150781/nightmares-are-tragic here]].

!!Tropes in this story:

* [[Main/AdvancedAncientHumans Advanced Ancient Ponies]]: The ponies of the [[WesternAnimation/MyLittlePonyTales Age of Wonders]], from the point of view of the [[WesternAnimation/MyLittlePonyFriendshipIsMagic modern Equestrians]]. Though Equestria's well on the path back toward that level of technology.
* AesopAmnesia: Luna experiences some of this, explicitly, right after being purged of the Nightmare at the end. Specifically, she loses a lot of her self-confidence, won in [[spoiler:her successful [[FightingFromTheInside fight from within]] against the Night Shadow]]. [[JustifiedTrope Justified]], as the combination of the drain to her form from the battle and the damage done to her by the Rainbow of Harmony severely weakens her and causes her to lose some of her memories, [[spoiler:especially her memories from the time when she was [[DemonicPossession possessed]] by the Night Shadow]].
* AfterTheEnd: [[WesternAnimation/MyLittlePonyFriendshipIsMagic Equestria]], from the point of view of the [[WesternAnimation/MyLittlePonyTales Age of Wonders]].
* [[AndManGrewProud And Pony Grew Proud]]: Specifically, the Ponies of the [[WesternAnimation/MyLittlePonyTales Age of Wonders]] attempted to power a global Wish spell with massive ''fusion reactors''. The backlash when the spell failed devastated the world and destroyed its advanced technological civilization, in the Cataclysm. [[spoiler:Actually, the spell ''worked'', and nearly destroyed the ''universe'' by crashing cause-and-effect -- the ultra-powerful [[ClockRoaches Cosmics]] intervened and [[RetGone eliminated]] that whole 'timeline' to salvage as much as possible, then caused the Cataclysm to create a new timeline where the Great Wish was never cast.]]
* AndroclesLion: As in the original show with Fluttershy and the Manticore, but taken UpToEleven in that Luna is manipulating the manticore by direct neural linkage through her "thorn" form, and Fluttershy's mind control powers block, counter and then completely overwhelm Luna's control. After this, Luna frequently refers to Fluttershy as the "mind-witch" -- and with respect -- when thinking about her.
* BadassPrincess: Luna, so very ''much'' Luna. She [[spoiler:overcomes her [[DemonicPossession Shadow rider]] in a [[FightingFromTheInside battle within]], tricking it, fighting it directly to save Twilight Sparkle, and then taunting it to distract it from the Element Bearers who are summoning the [[CareBearStare Rainbow of Harmony]] to destroy it]]. You rock, Luna.
* BeingEvilSucks: Directly argued by Princess Luna to [[spoiler:her Nightshadow, as part of her TheReasonYouSuckSpeech]]
* BittersweetEnding: As we know from "[[MyLittlePonyFriendshipIsMagicS1E2ElementsOfHarmony The Elements of Harmony]]", Princess Luna is free of the Nightmare. [[spoiler:And she's at last found the [[{{Reincarnation}} new incarnation]] of her OneTrueLove Dusk Skyshine. Only ''this'' time he's a [[GenderBender mare]], Twilight Sparkle. And this isn't an EveryoneIsBi fanon. Luna's clearly ''hoping'' that they can [[ReincarnationRomance wind up together]] [[IfItsYouItsOkay despite this obstacle]] , but there's no guarantee that this will work for either of them. On a far larger scale, the Nightshadows are massing on the Moon, obviously preparing to launch a major attack against the Earth, and the damage done to her by the [[CareBearStare Rainbow of Harmony]] has robbed her of much of her memories of her time possessed, so there's no guarantee that ''anyone'' will survive long enough for hearts, flowers and foals.]]
* BlackAndWhiteMorality: Mostly. The Shadows are pretty much pure evil, and both Princess Luna and the Mane Six are almost entirely good.
* CheckAndMate: "I win." For extra BadassPrincess points, Luna says this to the Nightshadow while it's ''in the middle'' of trying to ''literally'' MindRape her!
* [[TheChessmaster The Chess Mistress]]: Princess Luna is a brilliant tactician and -- once she's fighting a battle she can wholeheartedly believe in -- completely outwits [[spoiler:her possessing Nightshadow]].
* ClockRoaches: The Cosmic Concepts combined forces to eradicate [[spoiler:The World That Was Lost]] because it threatened to crash the continuum with its acausal paradoxes. [[spoiler:Cosmic Luna and the G3 Pinkie Pie directly dueled as part of the resultant battle; Luna barely won]].
* CodeOfHonour: One of the things that her Nightshadow [[EvilCannotComprehendGood fails to grasp]] about Princess Luna is that she is highly honorable, which helps her resist the worst acts to which it attempts to drive her.
* DemonicPossession: What the Night Shadows do to any pony who opens himself or herself to them. The composite entity is then referred to as a Nightmare or Nightstallion, depending on the sex of its pony form.
* [[DirtyCoward Dirty Cowards]]: The Night Shadows in general, because they have no love even for their own kind and hence no willingness to risk death even for the good of their own kin. Luna [[LampshadeHanging lampshades]] this in her TheReasonYouSuckSpeech:
-->'''Luna''': "I take that back. I think I do pity you. For when I die, I die knowing that I am part of something greater. When you die, you must die so alone. Yes. I pity you!"
* DyingAlone: After Luna delivers her TheReasonYouSuckSpeech and the Shadow attempts to MindRape her, it taunts her that she will suffer this fate:
-->Where are your friends now? the Shadow hissed, mocking her. Even I do not need you any more -- you are now more trouble than you are worth. You will die, here and now, alone in the dark, and I alone will inhabit this vessel. I will kill your friends, murder your species, destroy your world!
* [[EldritchAbomination Eldritch Abominations]]:
** The [[LivingShadow Night Shadows]], referred to as "anti-life" and strongly implied to have come from another Universe.
** The [[OneWingedAngel true Cosmic forms]] of both the [[OurAngelsAreDifferent Alicorns]] and the Dragonequii, which respectively resemble vaguely equinoid Biblical Angels (or King Ghidorah) in the case of the Alicorns, or Lovecraftian Outer Gods in the case of the Dragonequii.
* EveryoneIsBi: [[AvertedTrope Averted]]. [[spoiler:Luna still deeply loves her [[OneTrueLove ex-husband]] Dusk Skyshine in his new incarnation as Twilight Sparkle, but she fears that this cannot be carnal, as Luna is straight and probably so is Twilight]].
* EvilCannotComprehendGood: The [[spoiler:possessing Nightshadow]] cannot grasp [[spoiler:Princess Luna's]] motivations, and even in the final battle calls her abiding love for [[spoiler:Dusk Skyshine/Twilight Sparkle a "misdirected reproductive urge." Princess Luna]] actually [[LampshadeHanging lampshades]] this by pointing this out directly to [[spoiler:her possessing Night Shadow]] as part of a ploy in their battle.
* TheExile: The first chapter depicts [[SealedEvilInACan Nightmare Moon]] on the Moon, watching the Earth for a thousand years and alternating between madness and relative sanity.
* FanVerse: Much of the story is based on the concepts of the Fanfic/PonyPOVSeries of Creator/AlexWarlorn, though the depiction of the Nightmare state contradicts Alex's canon.
* FightingFromTheInside: What Princess Luna does subconsciously through most of the story, [[spoiler:and does consciously after she realizes that the Night Shadow is ''possessing'' her]].
* [[ChildhoodFriendRomance Foalhood Friend Romance]]: Happens between Moondreamer Finemare and Dusk Skyshine. They meet when Moondreamer and her sister Sundreamer are sent to a school and they wind up taking Dusk's part against bullies. When Moondreamer and Dusk reach adolescence, they fall in love, strongly enough that [[spoiler:Luna still remembers Dusk as her [[OneTrueLove great love]] four thousand years later, and uses this to break free of the Nightshadow's control]].
* GeniusBruiser: Princess Luna. She is not only a powerful Alicorn, but also a brilliant strategist and tactician, which [[spoiler:the Nightshadow hopes to use against Equestria, but which Luna herself winds up using against the Nightshadow in her [[FightingFromTheInside Fight From The Inside]]]].
* GoodIsNotSoft:
** The Mane Six in general, especially Applejack, Rainbow Dash, and Rarity.
** Also [[spoiler:Princess Luna, when she breaks free of the Nightshadow's control]].
* HeelRealization: Almost happens early in the story, when Nightmare Moon's appearance utterly ''terrifies'' Apple Blossom, Sweetie Belle and Scootaloo (not yet the Cutie Mark Crusaders). Princess Luna is a FriendToAllChildren, so this ''really'' bothers her -- unfortunately, the Night Shadow clamps down hard on the train of thought that would lead Luna to realize that she is behaving like a monster.
* HeroicResolve: Luna is [[spoiler:able to break the Nightshadow's hold over her soul (but not yet body)]] when she realizes that [[spoiler:Twilight Sparkle is her OneTrueLove Dusk Skyshine]] and the Nightmare is about to [[spoiler:kill Twilight]].
* IDieFree: Said word-for-word by [[spoiler:the spirit of Princess Luna]] to [[spoiler:her possessing Nightshadow]] after [[spoiler:the Nightshadow points out to Luna that if the Rainbow kills them both, this Aspect of Cosmic Luna will be rejected rather than incorporated into her Oversoul, due to contamination by Nightshadow. Princess Luna would rather [[DeaderThanDead die for real]] than remain a slave to the enemy of everything she loves]].
* [[IntangibleMan Intangibility]]: Two examples in-story, which may actually be related.
** Seems to be the natural state of the Night Shadows.
** Nightmare Moon can turn herself into "cold plasma" and in this form move undetected and seep into tiny crevices. It's not known if Luna can do this in her normal Alicorn Avatar form, or if this is an Alicorn ability in general.
* IShallTauntYou: Luna taunts the Nightshadow in a TheReasonYouSuckSpeech, claiming to pity it. [[spoiler:This enrages the demon to the point that it devotes all of its attention to attempting MindRape of Luna -- and loses sight of the fact that the Element Bearers are summoning the [[CareBearStare Rainbow of Harmony]] against it -- exactly what Luna intended to accomplish.]]
* LongingLook: Luna gives [[spoiler:Twilight Sparkle]] one at the party after she's been forgiven by her sister, then stops when she realizes that if she keeps this up everybody will know her feelings. Bonus points because her expression is actually in the original episode, though probably not meant to be taken that way!
** In ''Fanfic/FluttershyIsFree'', we learn that ''Rainbow Dash'' noticed that look, though she didn't figure out the reason for it. If Rainbow Dash noticed something emotional, there's a good chance that someone else did, too. Poor Luna.
* LiteralCliffhanger: Nightmare Moon undercuts a cliff ledge, causing Twilight, Applejack, Pinkie and Rarity to tumble down the slope. Rainbow and Fluttershy swoop to save Pinkie and Rarity, leaving Applejack and Twilight still in peril. Applejack manages to grab a protruding root, and Twilight to slow her fall enough that she's able to grab on to the edge of the steeper cliff below and hang on, enacting this trope.
* TheLostLenore: Luna still loves the (over 4000 years dead) Dusk Skyshine, who was the [[OneTrueLove husband]] of her [[{{Reincarnation}} earlier Aspect]] Moondreamer. She's spent many centuries hoping to be [[ReincarnationRomance reunited]] with him. When she discovers that [[spoiler:Twilight Sparkle is Dusk Skyshine, this gives her the [[PowerOfLove strength]] to defy the [[DemonicPossession possessing]] Nightshadow and begin FightingFromTheInside to free herself from the demon]].
* Magitek:
** As someone who has been a top aerospace engineer ''and'' a Cosmic Principle in past lives, Princess Luna is very much aware of the scientific underpinnings of the Universe, and it shows. For instance, she engages in the controlled ionization of the air to summon thunder, and is well aware that her SuperSenses are working on phased graviton emission and reception.
** In the backstory, the [[WesternAnimation/MyLittlePonyTales Age of Wonders]] eventually [[TheMagicComesBack rediscovered magic]]. They decided to channel the power of the Rainbow of Harmony into a global wish spell. How did they choose to power the spell? ''Terawatt nuclear fusion reactors,'' courtesy of [[OmnidisciplinaryScientist Doctors Sundreamer and Moondreamer Finemare]] themselves.
* MindRape: A horribly-literal example is attempted by her [[DemonicPossession Night Shadow]] against Princess Luna during their [[FightingFromTheInside battle within]] Nightmare Moon.
-->There was no dodging. It was too rapid, too omnipresent. She was overthrown by its sheer mass, she felt its vile smell, its evil presence surrounding her on all sides. She was rolled over within it, ended up on her back, with the Shadow covering every part of her. To her extreme revulsion, it began pressing in against every orifice -- that she knew that her spirit body was imaginary did not lessen the foulness of this, for she knew that if it could insinuate itself back into her she would suffer a fate far worse than any mere physical violation. She put all her might into her own shielding, keeping the Shadow from entering her and corrupting her soul. But she knew that she could not hold out like this for very long ...
* NotAfraidToDie:
** The Mane Six in general, particularly
*** Applejack, who ''voluntarily'' slides down a slope to a dangerous cliff edge to save Twilight from a fall, and later rodeo-rides a ''manticore'' -- when bucked, she sails through the air grinning in exhiliration, hands-off to Rainbow Dash, and then executes a perfect four-point landing. She wins Luna's admiration for this -- when Luna is still being ''[[AxeCrazy Nightmare Moon]]''!!!
*** Rainbow Dash, who ''tries to attack'' Nightmare Moon at her first appearance, and later raises a tornado around the manticore. When she gets hit by its tail, in a manner which might easily have proven fatal had the ''stinger'' connected instead of the tail itself, she goes flying, is dazed, and a few moments later joins a mass charge against the beast. Luna later realizes just of ''whom'' Dashie is a {{Reincarnation}} largely based on her attitude.
*** Twilight Sparkle herself, who coolly calculates her way through the whole final confrontation with Nightmare Moon. This not only keeps her alive in the mutual charge (when she teleports) but actually leads Luna to [[spoiler:recognize that Twilight is [[ReincarnationRomance Dusk]] [[OneTrueLove Skyshine]], triggering the release of Luna's own soul from the Nightmare's spell and beginning Luna's [[FightingFromTheInside fight from within]] against the [[DemonicPossession Night Shadow]]!]].
** Luna, to the point that she is willing to wind up DeaderThanDead (her current incarnation deleted rather than copied into her Cosmic Oversoul) if it means that she can defeat the Nightshadow and at least [[IDieFree die free]] of its evil control. Luna explicitly invokes this trope, when the Nightshadow warns her that Luna will die for real if she does this:
-->"You thought I didn't know that?" Luna laughed. "Cowardly shade, I've led Ponies into battle more times then you've tortured kittens. Thousands of Ponies have died under my command, every one of them fearing the same prospect, yet not letting it stop them from doing their duty. Do you imagine me any less loyal?"
* [[OmnicidalManiac Omnicidal Maniacs]]: The ultimate purpose of the Shadows is to consume all life in our Universe.
* PastLifeMemories: Two examples in-story.
** Pinkie Pie instantly recognizes Nightmare Moon as an Aspect of Cosmic Luna, which is why she screams even ''before'' Nightmare Moon materializes in the Ponyville Town Hall. The last time she saw any Aspect of Luna before that, Luna was ''killing her and destroying her world'', so Pinkie's fear is fully understandable.
** Luna has access to all her past life memories, especially those of Moondreamer, which becomes important because it lets her recognize [[spoiler: Twilight Sparkle as her reincarnated [[OneTrueLove husband]] and Rainbow Dash as a reincarnation of one of her best friends.]] This renders her unwilling to [[spoiler:kill Rainbow Dash]] and makes Luna determined to [[spoiler:fight the Shadow rather than let it kill Twilight Sparkle]].
* ThePowerOfFriendship: Two notable examples in-story.
** As in the original story, the friendship of the Mane Six enables them to attune and synchronize their Elements, producing the [[CareBearStare Rainbow of Harmony]].
** Princess Luna's discovery that [[spoiler:Rainbow Dash is the reincarnation of her old friend Dash Firehooves]] provide the initial impetus for her to begin to [[spoiler:break the domination of the Shadow over her own soul]], in part because [[spoiler:the Shadow insists that she try to kill Rainbow Dash, and Luna absolutely refuses to do this]].
* ThePowerOfLove: Since intense love actually ''hurts'' the Night Shadows, this is highly relevant to the story. Princess Luna [[spoiler:gains the strength to break free of the mental domiantion of her possessor when she recognizes that Twilight is the reincarnation of her [[OneTrueLove ex-husband]] Dusk Skyshine, and is filled with this emotion]].
* PowersViaPossession: The reason why somepony would summon a Night Shadow in the first place. Princess Luna became stronger than her sister by doing this, [[spoiler:at the cost of her free will]].
* {{Precursors}}: During her exile, Nightmare Moon discovers that the Moon contains many ruins and other artifacts left by pre-Equestrian and even pre-Pony civilizations. This is a throwaway, save for Dusk's old landing site, which is very emotionally significant to her.
* RealityWarper: Pinkie Pie, to a slightly greater extent than in canon.
* TheReasonYouSuckSpeech: Delivered by Luna to the Nightshadow
-->'''Luna''': "After more than a thousand years ... you still don't understand me -- or Ponies -- at all, do you? If I had room in my heart to pity you, I would. No love, no friendship -- nothing but eternal selfishness. Eternal greed, a hunger for the life you do not and cannot ever understand."
* {{Reincarnation}}: An important concept in-story: at least four characters knew each other in earlier lives.
** Princess Luna, who as an Alicorn Avatar ''remembers'' her past lives, used to be [[OmnidisciplinaryScientist Dr.]] [[MeaningfulName Moondreamer Finemare]], a top [[GadgeteerGenius aerospace engineer]] during the technological [[WesternAnimation/MyLittlePonyTales Age of Wonders]], and before that was [[EldritchAbomination Cosmic Luna]].
** Pinkie Pie was formerly [[spoiler:G3 Pinkie Pie, and is one of the last survivors of the World That Was Not, from which she derives her RealityWarper powers. Cosmic Luna helped destroy her whole timeline]]. It is unclear to what degree she remembers her old identity.
** [[spoiler:Rainbow Dash was [[WesternAnimation/MyLittlePonyTales Age of Wonders]] [[TheAce fighter-pilot]] [[GenderBender stallion]] Dash Firehooves, a good friend of Sundreamer, Moondreamer and Dusk -- and a member of the Amareican [[WesternAnimation/GIJoe Joe Team]]]].
** [[spoiler:Twilight Sparkle was [[WesternAnimation/MyLittlePonyTales Age of Wonders]] [[GenderBender stallion]] [[TheAce fighter-pilot]] and astronaut Dusk Skyshine, who was the husband and OneTrueLove of Moondreamer, which becomes important in triggering Princess Luna's HeelFaceTurn. It's also implied that she was G3 Pinkie Pie's best friend Minty]].
* ReincarnationRomance: [[spoiler:[[ShipTease Teased]], as Princess Luna still deeply loves her ex-husband Dusk but is uncertain if they can be sexually attracted to each other, since after all they are now both ''mares''. Unfortunately for them, this isn't an EveryoneIsBi fanon. Twilight Sparkle remains completely unaware of this throughout the tale]].
* ShapeShifting: One of Nightmare Moon's powers. The sequel ''All the Way Back'' confirms that ''all'' Alicorns can at least theoretically do this, but that Luna is particularly good at it.
* ShipTease: Luna is never able to so much as tell [[spoiler:Twilight Sparkle]] [[OneTrueLove who]] [[spoiler:she]] used to be to her in a [[ReincarnationRomance past life]]. Then again, [[spoiler:they're both straight females]]. There's enough UnresolvedSexualTension coming off the Moon Princess to fuel a whole armada of ships, though!
* TheSocialExpert: Two are shown.
** Rarity Belle, as in the original episode, befriends the river serpent. Luna, watching this, is envious of Rarity's charm.
** Princess Celestia leads Twilight to ask for permission to stay with her new friends, which is exactly what [[TheChessmaster Celestia]] wanted her to do. Luna, who has known her sister for a [[TimeAbyss very long time]], thinks the following (addressing Twilight in her mind with the name of her earlier incarnation):
-->'''Luna''': She's going to manipulate you. Might as well let her do it, Dusk. Her games generally turn out well, at least for ponies she likes. Anyway, she's hard to resist. Trust me on this one.
* SugarApocalypse: The destruction of The World That Was Not timeline by the Cosmics, remembered well by Luna and dimly by [[spoiler:Pinkie Pie]], who fought each other there.
* SugarBowl: The World That Was Not, the timeline from which [[spoiler:Pinkie Pie]] originated.
* SuperSenses: Cosmics who take Immortal Incarnations all get these, tailored to their specialty. Princess Luna has both active and passive gravity detection: she can emit a graviton pulse and see by the return.
* [[TakeMyHand Take My Hoof]]: When Twilight is in her LiteralCliffHanger, Applejack risks her life by letting go of the protruding root and sliding to the edge of the cliff. Being an [[ActionGirl Action Mare]], Applejack times it perfectly and leans over to grab on to Twilight's forefeet -- with her own Earth Pony sucker pad / telekinetic grip. Which [[SubvertedTrope isn't strong enough]] to pull Twilight up over the edge to safety. Uh-oh.
* TalkingIsAFreeAction: [[DeconstructedTrope Deconstructed]]. Twilight Sparkle's lecture to Nightmare Moon nearly gets her killed: she survives only because [[spoiler:Luna is already FightingFromTheInside against the Nightshadow]].
* [[TeleportersAndTransporters Teleportation]]: Another Alicorn ability, and also one possessed by Twilight Sparkle even before she becamse an Alicorn. Celestia and Luna are both especially good at this, and Twilight manages to accomplish it at least once in battle.
* ThisCannotBe: The reaction of the Nightshadow to [[spoiler:Luna's first ''overt'' attack on it in her campaign of FightingFromTheInside.]]
-->"What?!!" it howled, twisting, turning to defend its [conceptual] spine from what would have been a shattering blow. "No! You cannot have ... "
-->[[spoiler:Luna has]].
* TimeAbyss: Princess Luna is over 2500 years old in her current incarnation, and almost as old as the entire Universe in her Oversoul as the Cosmic Concept of Gravity.
* [[OneManIndustrialRevolution Two-Mare Industrial Revolution]]: What Celestia and Luna have been trying to accomplish since they started to unify Equestria, and what Celestia has to largely do on her own after Luna's rebellion -- namely, bring about a new Age of Wonders -- hopefully one that won't end in Cataclysm this time round.
* VillainProtagonist: This is fundamentally Recap/MyLittlePonyFriendshipIsMagicS1E2ElementsOfHarmony retold from Nightmare Moon's point of view.
* WhatYouAreInTheDark: In the final battle, in which [[spoiler:Luna is FightingFromTheInside, the Nightshadow tries to break Luna's resolve by pointing out that as far as the Mane Six know she's their enemy, and a traitor to the Realm. Her response?]]
-->'''Luna''': [[spoiler:That does not matter ...My future does not matter, beside the future of all Ponykind. And I stand by my kin, my friends -- my beloved.]]
