The Everfree Slayer

Rainbow Dash trots inside the Carousel Boutique and goes to the front counter. She looks at the white unicorn standing there and calmly says, “Rarity… I need to talk to you in the back…”

Rarity frowns and says, “Um, of course darling!”

Rarity trots to the backroom with Rainbow Dash in tow. There are no customers inside the boutique at this time of the day and all the racks of pony cloths are neatly arranged and laid out, just as Rarity had organized them, not more than an hour ago. She reaches the wooden door in the back and causes the doorknob to glow blue with her mind before the door swings open to the right, on the inside. She steps inside and Rainbow soon follows her.

The backroom is roughly 15 feet wide and 10 feet long with wooden walls and metal shelves arranged with many different garments and materials on it on the back wall, opposite the door. Rarity turns to face her pegasus companion inside the wooden room, after Rainbow trots in from the door to the side and asks, “What is it dear?”

Rainbow Dash turns her body to look behind her before trotting to the door and looking over the deserted shop carefully. She finally nods and backsteps to use her left forehoof to shut the door quietly before turning to face the unicorn again and sighing.

Rarity can only patiently wait for the pegasus to speak as Rainbow clears her throat.

“Rarity!” Rainbow Dash says with a serious look in her magenta eyes, “I need to tell you something…”

Rarity leans forward wide-eyed, “What is it, pray tell darling?”

Rainbow blinks, “I’m the Everfree Slayer…”

Rarity stares at Rainbow with her eyes wide open as her mouth grows small, “W-WHAT?”

Rainbow blinks again, “I killed another victim last night… Their body is buried in a shallow grave, about three-hundred yards just east of the train tracks… I could show you the place…”

Rarity takes a deep breath, “Why are you telling me this?”

“Because…” Rainbow sighs as she looks down, before turning her head back up at the white unicorn, “Because I don’t want to do this! I don’t want to kill anypony!”

Rarity narrows her eyes somewhat, “I see… Then why do it? Why do you kill victims?”

Rainbow shakes her head before looking back at Rarity, “I don’t know, okay? I don’t want to do this! Not anymore, not ever, and I didn’t want to do it earlier! I don’t know why I go out at night and kill! I just do it!”

Rarity frowns at the dire news, “Uh, so what do you propose we do, Rainbow dear?”

Rainbow gulps, “I want to sleep here with you, until further notice…”

Rarity narrows her eyes, “Why?”

“Because…” Rainbow blinks, “Because I think if I was with somepony at night, I won’t want to go out and kill… I’ll just crash on your couch and be gone early in the morning…”

Rarity smiles, “Actually, I have a much better idea!”

<*****>

“Ugh!” Rainbow grunted as she moved her two forehooves, now firmly tied together by a dark tan rope as she lay on her side on the right end of Rarity’s bed while staring up at the fashionista from the pillow. “Why do you have ropes of these specific lengths anyway?”

Rarity only smiles and giggles as she stares at the daredevil from her haunches on the other side of the bed…

Rainbow’s eyes widen, “Oh my Celestia! Rarity, you’re gonna have to tell me what you’re into later, but right now, we need to keep me and everypony else in town, safe!”

Rarity smirks, “Well, I suppose I should finish the scene with a ballgag and buttplug? What size does your rectum prefer, darling?”

Rainbow’s eyes widen as she starts out emphatically, “What? No! We just need to tie me up, so I don’t kill anypony! Why do we even need that?”

Rarity can barely contain her giggles, “Well, if you’re going to be my new slave, we must outfit you properly, no?”

Rainbow’s eyes widen dramatically as her mouth is fully agape.

Rarity starts to giggle hysterically!

Rainbow frowns and groans…

Rarity looks down at the pegasus, “Okay, look darling! If what you say is true, then I don’t believe you’re actually the killer… Somepony or something is obviously controlling you at night… You’re going to sleep here and I’m going to watch you! I have the new Shadow Spades book and coffee right over there! I’ll calmly read my book while you slumber and we’re going to see what happens!”

“Wow Rarity! You uh, really thought this out, didn’t you?” Rainbow stammers out while she’s tied down on the bed.

Rarity smirks, “Of course darling! You should expect nothing less! Now, do you need a sleep mask so you can rest while I keep the lights on and read?”

Rainbow frowns, “Uh, I guess?”

Rarity smiles, “Right!” She looks to the white sleep mask with ruffles on the edges and hearts on the eyes on the dresser on the other side of the room from the bed, and causes it to glow blue and float over Rainbow’s head as she calmly says, “The gag and plug can come later I suppose?”

“Ugh!” Rainbow closes her eyes as she leans forward slightly before staring up at the white unicorn and says in her raspy voice, “Rarity! I need you to take this seriously!”

As the mask glows and floats over Rainbow’s head and the band extends for her head, Rarity giggles slightly, “I’m terribly sorry darling! But I just think it’s hilarious that I actually have you tied up and blindfolded on my bed and we’re not playing!”

Rainbow’s eyes are wide as saucers as the mask snaps over her and cute dark red burgundy sparkly hearts now take the place of the eyes on her face.

“Rest well sweetie! I’ll be in my chair!” Rarity says before Rainbow can hear the resounding clack of her hooves touching the floor followed by trotting as Rarity makes her way to the chair on the other end of the room. Rainbow hears her say, “Hmph!” as she daintily mounts the chair and then small sipping noises as Rarity enjoys her coffee. She says lowly, “Well, that’s a touch too hot! We’ll just have to let that sit then, won’t we?” And then she says louder, “I love you Rainbow Dash!”

“I love you too!” Rainbow chimes out before she leans forward slightly and does her best to get comfortable in her bindings.

<*****>

When Rainbow wakes, she starts suddenly as she’s bound and blinded by the covering over her face. She no longer feels the bed or anything at all as she suddenly attempts to thrash in the air as she can now feel a rope solidly holding both sets of legs to her body. She cries out, “Where am I? What’s going on? Help!”

Rainbow then hears the soothing voice of Twilight Sparkle say, “Rainbow! You tried to escape! Rarity tied you up more… Do you remember any of this?”

Rainbow stops moving in the air as her tightly bound body is held in the air by a purple glow, “Uh, not really? I just know I was tied up on Rarity’s bed with a mask on and then, I woke up here tied and in the air like this! W-what happened?”

Rainbow hears Rarity say, “Well, you had made your way to the floor beside the bed. I didn’t know what else to do with you and so, I tied you up with the extra rope I have…”

“I…” Rainbow blinks underneath the mask, “tried to escape? Even though you were in the room with me?”

Twilight says incredulously, “Yes Rainbow! Also, you’re clearly under the effects of dark magic at night! Why didn’t you just come to me in the first place?”

“Well…” Rainbow leans forward in mid-air suspended, “You’re a government official now! I thought that if I could just keep myself from killing at night, this would all go away? That’s why I talked to Rarity… I didn’t want to go to jail if I didn’t have to…”

There’s a small pause before Twilight says, “So, your whole plan hinged on the theory that Rarity, by herself, could keep you from killing and that you would abruptly stop killing at some point for no discernible reason?”

Rainbow widens her eyes underneath the mask, “Well, it seems kinda dumb, when you put it like that!”

Twilight adds sardonically, “You think?”

Rainbow sighs, “Okay, so you think there’s dark magic involved then?”

Rarity says, “Well, what else could it be dear? I mean, you’d have no reason to lie to me about something like this and if what you’re saying is true, then something must be making you do these things!”

Rainbow barks, “Yeah, but what?” She shakes her head while contained in the rope bundle. “I just don’t understand. I mean, I never wanted to kill anypony, even ones I really hate! And now, I just kill random strangers!”

“Well, that’s what we’re going to find out!” Twilight says before Rainbow’s mask glows and it lifts off her head.

She sees a purple alicorn standing there just to the right of the door while Rarity stands off to her left side as she’s held in the air, with rope firmly tied all around her. She looks at the purple pony, “Okay, so how do we find out then?”

Twilight frowns, “Well, that’s just it! We need to be able to trace this magic and I can’t do it when it’s not affecting you… You’ll need to go back to sleep so I can cast the binding spell that allows me to see what influences are affecting you…”

“Ugh!” Rainbow groans as she throws her head back. She stares at Twilight with narrowed eyes, “Alright fine! Put the mask back on me!”

<*****>

Twilight Sparkle sits in a chair opposite to the bed and reads the mauve book, now magically floating before her face in a violet glow, when suddenly, Rainbow Dash starts to violently thrash on the bed as she grunts. Twilight looks up at Rainbow and magically causes the mask to flay off Rainbow’s head as her body thrashes violently in the bed while still trapped in her bindings, “Rainbow! Wake up! Are you there?”

Rainbow Dash’s eyes now glow an eerie green color as she stares back at Twilight, seated to the left of the bed from Rarity and says, “You’re both in danger! I’m going to kill you!”

Rarity looks up from her book on the chair and says frantically, “Uh, Rainbow dearest! You need to calm down!”

Rainbow twists her body to stare at Rarity with her neck staring down at the rest of her body, “No! You need to die!”

Rarity frowns, “Oh dear!” before looking to her left at Twilight, “Any idea on how to find the source of this dark magic?”

Twilight stares at Rarity, “Not yet!” She turns her head left, back towards Rainbow, “Who is controlling you? Why are you killing ponies?”

Rainbow looks back up and smiles psychotically at Twilight, “Wouldn’t you like to know!”

Twilight frowns, “I know you’re in there, Rainbow Dash! Please!”

Rainbow starts to giggle, “I’m still going to kill you!”

Twilight groans, “There’s gotta be a way to figure out what’s causing this!”

Rainbow begins to chant, “I’m going to kill you! I’m going to kill you! I’m going to kill you!”

Rainbow continues to chant as Rarity frowns and stares at Twilight, “Worry not darling!” before she stares at her closet behind Twilight and makes it glow blue as the door opens.

Twilight looks to her left and sees two black straps with a red rubber ball in the center, floating it’s way in the air while glowing blue towards Rainbow Dash on the bed, who’s still chanting…

“I’m going to kill you! I’m going to kill you! I’m going to, MPH!” Rainbow starts as the glowing gag flies around her head from the far side of the bed and fills her mouth before the straps close behind her head and she feels the buckle clasp firmly to hold the gag in place. The gag stops glowing a moment later…

Twilight looks over at Rarity, “Why do you have all of these bondage implements anyway?”

Rarity widens her eyes at Twilight, “Never mind that darling!” She narrows them, “The important thing now is, we need to find out why Rainbow is doing these things!”

Twilight shakes her head slightly and blinks at Rarity, “Right!” She looks back at Rainbow Dash, still with the eerie green glow that still encompasses her eyes and she thrashes on the bed, now desperately trying to make her way to the other side, opposite to Twilight. “And I know I’ve seen that same color in the eyes of ponies before…” She frowns before lowering her head and causing her purple horn to glow a vibrant violet color and a magical beam of light soon shoots from the tip to Rainbow Dash, still trying to scoot to the back side.

Rainbow’s frame glows and floats in the air before a large mass of black crystalline magic starts to exit her body and swirl towards the window and she abruptly stops thrashing. She breathes in and out through her nose as the gag is still inside her mouth and her eyes widen towards the princess.

Twilight leans towards Rainbow, “Rainbow! Are you in there? Can you hear me?”

Rainbow can only nod at the princess.

Twilight says emphatically, “Rainbow Dash! You’re definitely under the control of dark magic at night… Do you know when you started to kill ponies?”

Rainbow shakes her head no.

“Okay!” Twilight nods, “Have you been outside of Ponyville at any point in the near past? Maybe in the badlands to the south or the Everfree north of here?”

Rainbow widens her eyes.

Twilight giggles, “Oh! You’re gagged!” before staring at Rainbow and forcing the ballgag to glow purple and undo the buckle behind her neck and slide upwards off her head.

Rainbow coughs and says in her croaky voice as spittle dribbles out the right side of her mouth while she’s suspended in the air, “Well, I was out cloudbusting to the east and I saw a strange green glimmer on the ground… I flew in to check it out…” She abruptly stops talking and closes her eyes…

Twilight leans forward wide-eyed, “You went to check out what, Rainbow?”

Rainbow Dash opens her eyes and looks to Twilight. The purple alicorn can see that her eyes are once again, the same sickly green color as a clear curved horn of the same color begins to grow out of Rainbow Dash’s head and she grins at the alicorn sadistically.

Twilight looks at Rainbow and chants melodically, “Unable to hurt others and held in place, make this pony bound here, in this space!”

Suddenly, a forcefield forms around Rainbow as she cackles maniacally to the alicorn, “You think your puny magic can stop me?”

“Rainbow!” Twilight starts at the pegasus, “Can you hear me?”

Suddenly, Rainbow’s eyes stop glowing the green color and her pupils and magenta irises are once again visible as the horn suddenly vanishes. She can no longer move her head inside the mauve energy field, but she can utter, “Uh, yeah Twilight? What happened?”

Twilight frowns, “You had another night terror…” She looks up, “That’s strange! I still can’t seem to detect any outside magic?” She looks back down at Rainbow, “Do you remember anything?”

Rainbow Dash frowns, “Uh, not really? Why is there a forcefield around me?”

“Never mind that! What did you check out east of town, Rainbow?”
