A Quiet Chapel

The Betrayer growls, her sharp teeth bared. “You can pray, little one. But no pony will hear you.”

Sister Fluttershy whimpers. How can this be happening? She was simply minding her business, doing her nightly check of the candles. The same thing she's done night after night, every single night the same, for years. "Oh, goddess, please..." She whispers, then flinches at the sharp laughter above her.

"She cannot hear you, will not help you, and does not know you exist. Such pathetic piety." says the massive demon, her armored hooves scratching at the temple floor. Fluttershy rolls over, attempting to climb onto her hooves to run - but a hoof on her shoulders stops her, pressing her chest against the cold floor. "Simply pathetic..." the Betrayer murmurs, such a soft tone for such a large beast. "You worship Her, yet you don't know the first thing about Her."

Cold, prickly magic envelops Sister Fluttershy's body, feeling like ice against her fur. She is lifted, and turned, and brought eye to eye with Nightmare Moon. "You call me the Betrayer, yet you do not know a damn thing about betrayal. You parrot what you are taught without pausing to think for even a moment." Venom drips from every word she speaks, the slits of her pupils boring holes straight into Fluttershy's soul. She bares her fangs and hisses, and Fluttershy begins to shake uncontrollably from fear.

She wakes with a start, and a quiet little scream.

Beside her stands Sister Cheerilee, one hoof outstretched, a concerned expression on her face. "Sister Fluttershy? I'm sorry to wake you early, but you where shaking like a leaf. Are you alright?"

Bed. Friend. Sleep? Dream. Fluttershy can hardly contain her tears of relief. It was just a dream.

"Y-yes, Sister Cheerilee. I'm fine now. It was just a nightmare."

The second time it happens, she's just out front of the Temple, staring up at the stone statue of the Goddess of the Sun. It was built a long time ago, but the convent works hard to keep it pristine - its age does show through, however. Normally.

Now it is quite literally brand new, the stone workers tools still sitting beside it. Sister Fluttershy looks around, confused, and sees that her temple is brand new as well - just as it looks in the paintings made the day it was built. She looks up, and a massive pale moon stares down at her, completely devoid of the Mare.

"Isn't it so beautiful under My moonlight?"

Fluttershy jumps when she hears the voice. "It's just a dream..." She whispers, trying very hard to wake herself up.

"A dream, yes. I would hardly say 'just' a dream, however." the Nightmare says, walking up next to Fluttershy. She stands nearly eye-to-eye with the statue, and stares at it with such a forlorn expression, Fluttershy nearly forgets to be afraid.

"She always looked beautiful under My moonlight, you know." the Nightmare murmurs.

Fluttershy looks up at her. At her shiny black fur, at her ethereal mane and tail, at her demonic half-bat wings. At her face, so angry before, now...mournful. Fluttershy feels suddenly the same way she does when she looks at a little animal stuck out in the snow. She swallows the rest of her fear, takes a deep breath, and tries her best to be brave.

"You...you feel like. Um. Like you're the one who...who was betrayed, don't you?" She says, preparing for another possible outburst of anger.

Instead, the Nightmare turns and looks at her, surprise visible on Her face. "...Yes," She says, "I do." She turns to face Fluttershy, her face appearing a bit more guarded now, and asks - "Why do you care?"

"I try my best to be kind to everypony. You...You look like you need someone to care."

By the eighth time it happens, Sister Fluttershy isn't scared anymore. The Nightmare hasn't hurt her at all since that first dream, and has seemed to slowly open up a little.

"You ask good questions, Sister." the Nightmare says, standing over Fluttershy. Her sheer size is still intimidating to the pegasus, but so are Stallions that walk too loudly, so she isn't that much more anxious than normal.

"Yes, my story matches fairly well with what is told in your scriptures. I was once a powerful Goddess, just like your Sun. We are...Like Sisters, in the mortal sense. Born of the same magics. Your story, however, does not contain the full truth.

"I once followed the Sun blindly, as you do. She was my everything. She was beautiful, and strong, and She protected me - and I loved Her for this. But eventually, I wiped away the stars from my eyes. We had many disagreements. She wished ponies be kept ignorant of the greater workings of the world, and I the opposite. She wished to step in and protect protect ponies from themselves, and I disagreed. She wished your kind be placid, agreeable toys - loving and loved by Her, following all of Her rules. I lit the fire of independent thought under the ponies of Eden - the first town - and gave the mortals their free will. I believed her cruel for creating a sapient being that could not think for itself, and She believed me cruel for giving that being the ability to feel pain.

"Life is not real without a spectrum, I said. Good and Bad, Chaos and Order, are all required. She disagreed. That was the beginning of the end.

"We rarely saw each other, after that, each only entering Equs during our time. Her, the day - I, the night. I came into the world and saw it wild and wanting - I made thunderstorms, and I made wolves, and I made ecstasy in the dreams of ponies. She made cities, and Temples, and rules to follow. She ordered ponies to tame my storms, drive away my wolves, and refuse my pleasures - all things wild and wonderful where sinful to Her Ponies.

"Don't you see, Fluttershy? How absurd it is to deny yourself the pleasures and experiences your body can give you? How wonderful it is to be in a world that grows and changes around you, in a body that allows you access to delicious flavors and passionate feelings?" the Nightmare stands suddenly, Her mane and tail whipping about rapidly in her excitement. "She locked me away because I love my ponies differently than She does. She turned them all against me, called me the Betrayer - am I not the one betrayed? am I not equally deserving of love, of devotion, as that She has? I made the Moon, the Forests, the animals, the roses! Yes, I made the thorns! Are they not that much sweeter for it?!" She sounds nearly hysterical now, and catches herself - she sighs, and lies back down.

"She said that mortals should live a life safe from harm. I say, you should live a life that is worth the harm." the Nightmare says quietly, her head dipping low.

Fluttershy, at a loss for words, does the only thing she can think of. She gives the massive Mare a hug.

"You must be so lonely, Goddess..." She whispers, clutching tightly onto the Nightmare's neck.

Sister Fluttershy struggles to keep up with her duties in the Chapel. Her prayers now feel empty, and her mind wanders. Exactly who is it she has devoted her life to?

She has heard the story of creation from the mouth of a Creator. How can the scriptures, any holy book, any word written by mortal hooves even try to compare?

She sees the animals through the windows, out there in the Everfree, and she feels envy. She thinks of going out and tasting delicious things, and she feels gluttony. She thinks of allowing her body to lead her...and she feels lust. She has heard whispers of depraved ponies, Cultists, that follow the Betrayer. The Fallen Goddess. Every day that passes, singing the praises of the Sun - she wishes more and more to go out and find them. To frolic with animals and be Ever Free herself.

"Sister Fluttershy!" A loud voice shouts in her ear. She squeaks, dropping the broom she was idly holding, and shrinks towards the floor. Sister Cheerilee stands above her.

"I'm sorry to yell and scare you, but you weren't responding to anything else. You've been leaning on that broom and staring out the window for ten whole minutes! I've been counting!" The irritated pink mare shouts, disapproval plain on her face. "What is with you lately? You've barely finished your chores, you've mumbled your prayers, and you've been late to morning service every day for two whole weeks!"

Fluttershy shrinks further as she listens to the tirade, trying to come up with an excuse, anything other than the truth. Lying, now...That's another sin.

When did Sister Fluttershy become such a sinful mare?

She's out in the woods, in a clearing - the pale moonlight kissing her spread wings. She's naked outside of the bathhouse for the first time in years - at least, in her dream, she is.

"Mmm, What a shocking yet delicious way to find you, Sister." the Moon says from behind her, and Fluttershy can't help but smile. She rolls over, thighs pressed together to hide her shame, and stares up at the Goddess. All the fear is gone, and all Fluttershy feels now is love, adoration, and devotion when she looks upon this, the most beautiful Mare she's ever seen.

"Please, um, Goddess. Just call me Fluttershy."

"Oh? Having a change of heart, Fluttershy?"

"I'm...I'm leaving the temple when I wake up. I want to hunt for a way to free you, Goddess."

The Moon laughs, and grins. "Why, Fluttershy, I'd almost say you're trying to seduce me..." She purrs, sitting down in front of the prone pegasus. "Trying to fit in one last festival of sin while you're still a Mare of the Cloth?"

She turns red all over, but still, Fluttershy nods. Carefully, at a snails pace, she spreads her legs - and reveals her untouched flower. "Please, Goddess..." She murmurs, "Take me as your own."

The Moon doesn't respond with words. Instead, She gently lies down, and runs Her long, forked tongue over Fluttershy's clit. The pegasus moans quietly, then louder as the licks build in intensity. Her wings flex and strain against the grass, and her whole body tingles with intensity. The Moon suckles on her clit, then snakes Her tongue inside, rolling its length around and pressing it into all the sensitive parts Fluttershy never knew existed. She switches between tonguing and suckling and licking, and adds in little nips to those yellow thighs. "Pleasure is nothing without pain, Fluttershy. Doesn't it excite you? Doesn't it feel like you're drowning , but you never want to leave?"

Fluttershy tries her best to nod, but her body isn't listening to her right now. "Y-Yes...Yes! YES GODDESS YES!" She whispers, then says, then shouts her approval, quickly rising to a peak she doesn't understand, but needs more than air. She feels fangs sink into her thigh, then quickly sucking on her clit - and she falls over that edge into oceans of ecstasy.

All night, she rides that high - She learns what an orgasm is, and cums over and over and over again, her new Goddess listening to every prayer she makes. Gone are the days of a distant divinity - Now Fluttershy understands the love of the divine.

After several hours, the Moon stops and lets her rest. Then, just before dawn, She asks Fluttershy a favor.

"My prison is both inside the moon and inside of Tartarus. With the right rituals, you will be able to unlock the magic seals, and weaken the chains that bind me. Seek out the hidden knowledge of the world, and find a unicorn to help you. Together, you can free me."

Fluttershy smiles at Her.

"Yes, Goddess."
