She's not crazy, no matter what anypony else says.
Humans exist, right? After all, how couldn't they? The whole world seems to be built with them in mind. Is it too hard to believe they at least existed?Lyra asks herself this question a lot, as she's been utterly devoted to finding the truth for the past few years. When Lyra finds what she believes to be indisputable evidence in the form of a lyre, she becomes determined to prove their existence, no matter how much society (and her roommate) object.This My Little Pony: Friendship Is MagicFanfic by JasonTheHuman has been featured on Equestria Daily and can be found here. There are also two official side stories: the February Write-Off entry Caretakers and the decidedly non-canon April Fools' Day chapter Truth vs. Fiction (a sequel to the author's earlier fic Gurren Jesus).This story now has its own theme song!An audio-drama is in the works, chapter one is already out and can be found here.
This Fanfic contains examples of:
Aerith and Bob: Lyra considers how some ponies have human names (such as Pony Joe) to be evidence.
Ancient Astronauts: Celestia reveals humans were like these, though how technologically advanced they were is still unknown.
Arbitrary Skepticism: In an inversion of what's typical to be skeptical about, Rarity scoffs at Lyra's claim that day and night on Earth change entirely on their own.
Anger Born of Worry: when Bon-Bon threatened to throw Lyra out of the house, it was partially because she wanted to protect her. She did almost crash with a cart she brought to life in a valley, though...
Cassandra Truth: Nopony believes Lyra, about anything she says. Not even Twilight, the one pony who would actually listen to her, who actually has any inclination to for inquisitive fact finding. Lyra appropriately throws this back in Twilight's face when she recounts how nopony believed Twilight about Nightmare Moon.
It is played for drama when Lyra ends up in the human world. She knows that most people wouldn't believe her past, and struggles to find a good cover story. When she tells Audrey the truth about her, Audrey loses a lot of her faith in Lyra, who can't even tell the truth to her human family, and pretends to be amnesiac... up until Discord turns her back into a pony.
Chekhov's Gun: Lyra's interest in Greek culture and history, which she attributes to a half-pegasus heritage. It's actually a further clue to her own Greek heritage on her human father's side, immediately identifiable by the name "Michelakos".
The cutie-mark shaped necklace that Lyra receives from Princess Celestia before being sent back to the human world, turned out to be charmed, and when Discord turns Lyra back into a pony, it sends her back to Equestria, allowing her to bring the Elements of Harmony to Earth and stop him.
Clarke's Third Law: When the ponies arrive in the human world, they keep wondering what kind of magic the humans are using to power things like cars, and Lyra has to explain that it's not magic, although she still doesn't really understand it either.
Contrived Coincidence: It's a bit of a stretch for Lyra's human father to be so incredibly famous that literally the fourth person she has more than a fleeting conversation with recognizes his photograph.
Deadpan Snarker: Paul, It's enough to get him to wield the Element of Laughter against Discord in Chapter 30.
Deconstruction: The story deconstructs the popular Fanon interpretation of Lyra having a fixation on humans. It's by no means dark, but it shows that no matter how benign Lyra's behavior and beliefs are, they are nevertheless still deemed inappropriate in Equestrian society, to the point of becoming an increasingly more severe point of contention with her roommate. Lyra becomes paranoid, believing that pony's ignorance of humanity is all a government conspiracy.
Deliberate Values Dissonance: Lyra is saddened and horrified by humanity's history of conflict and to a lesser extent their consumption of meat the former she learns about through studies in the human world, the latter from eating a ''Big Mac'' while her human friends tend to be nonchalant about it. Also Lyra mentioning being on her own since she was 12 (due to pony aging standards) shocks Audrey, a human girl who is still considered a minor, and is slightly put off by her eating a plant. This trope abounds as Lyra struggles to adapt in the human world.
Distant Finale: The final chapter takes place one month after the previous chapter.
Dramatic Irony: Played for Laughs, when Bon-Bon recieves Lyra's letter that she won't be returning home, while offering rent for nearly 6 months. Bon-Bon is overjoyed that Lyra got over her human obsession and found a musical career that pays so well. Of course, Lyra was just turned into a human.
When the Mane Six arrive in New York, Applejack speculates that Discord has already done a number on the place when they see the cityscape, and is baffled when Lyra tells her what she sees is perfectly normal. Consequentially, when they get separated, the cast is hopelessly lost because they can't tell what's normal and what isn't. For bonus irony, Discord is showing surprising restraint compared to his antics from his prior appearance in Ponyville.
Discord: Surely you must know how fascinated humans are by the idea of the end of the world. They’re just begging for it to come, Lyra. I’m only doing what humans have been looking forward to for years now.
Genre Savvy: Thomas, who can tell that Lyra's lyre necklace is important simply from the fact that she got it from Celestia. Then again, he is a writer of Troperiffic fantasy.
Gilligan Cut: Bon-Bon deduces after receiving Lyra's letter that she's finally moved on from her human obsession. At that exact moment, Princess Celestia has just turned Lyra back into a human and is sending her out of Equestria.
Good Samaritan: Audrey takes in Lyra after finding her on the streets of Des Moines, which earns her the Element of Kindness.
Grass Is Greener: Although Lyra doesn't find Earth to be perfect she cannot fathom why Humans are so fascinated by something as "boring" as magic and other things we consider "fantasy".
Intrigued by Humanity:Lyra obviously, and more or less the main plot point of the story. The first part the story shows the consequences of believing in a creature that has not been proven to exist, and adopting their habits:namely the skepticism of her peers (and the frustration of Bon Bon) and the fear that the government is hiding the fact that they exist. Her obsession is attributed to the fact they she was in fact born a human.
Masquerade: Lyra believes the supposed nonexistence of humans is this, and she appears to be right.
Lyra appropriately points out all kinds of inconsistencies within the Hearths Warming Eve story that everypony else takes as almost literal fact, her roommate dismisses it offhand.
Confrimed as true.
Mistaken For A Spy: Played for Laughs, when Twilight was asked by Princess Celestia to find out as much about humans as she can, and so naturally goes to the human-obsessed Lyra for help. However, this was just after Princess Luna gets angry at Lyra for the mere mention of humans, and assumes Twilight's there to find out how much she knows and eliminate her. This goes into insane and hilarious levels of paranoia, even after Twilight's intent is proven genuine.
Mythology Gag: Lyra's birthname was Heartstrings, but she was more accustomed to the name Lyra after reading it in a book, a reference to the fact that Lyra's original name in the toyline was Heartstrings, but the fandom demanded that she be renamed Lyra.
Nice Job Fixing It, Villain: If Discord hadn't turned Lyra back into a unicorn, she wouldn't have been able to use Celestia's enchantment to return to Equestria, contact the Mane Six and bring them and the Elements of Harmony to Earth. And the elements were of use, though not as expected...
The Not-Love Interest: Despite the two practically being the OTP of the fandom, Lyra and Bon-Bon are simply roommates in this story. Bon-Bon even threatens to kick Lyra out at some points.
Lyra: I play the lyre. I heard that’s not very popular around here, though. Nathan: A lyre? I guess if you found someone who played ocarina, you could start a band. Lyra: Really? Audrey: She doesn’t really get sarcasm.
Also from chapter 23:
Lyra: I was reading that history book you gave me and it said that America had been in wars. A lot of them, actually. Paul: News flash. I’ve never heard that before. Lyra: So… It wasn’t true? I mean, if there had really been so many, you would have heard – Paul: That was sarcasm, Lyra.
Saying Too Much: When questioned about humans, Luna immediately begins ranting about how better off everyone is without their influence. Then she orders Lyra to drop everything regarding the subject, and promptly storms off.
Shout-Out: When Lyra first meets Nathan, he's wearing a shirt with the word Aperture on it.
Trans Nature: In a way. Although it is clear that she wanted to become human despite not knowing they had gone extinct in Equestria and not knowing she was one from another universe, later on, she starts having dreams of turning into an unicorn again and started showing signs of being homesick. No one knows for certain, but there is the possibility that part of her wanted to stay an unicorn and remain living in Equestria.
True Companions: Lyra and her human friends. They are able to defeat Discord with the Elements of Harmony.
Unfortunate Names: After arriving in the human world, Lyra name-drops Twilight Sparkle to her new human friend, Audrey. She assumes Twilight must have been raised by hippies and that she must be teased "because of the books."
