Author's Note

Welcome! This was originally pure porn, but my editor made me add real story because "Who writes 30k words of just porn?". So now you have 40k words of mostly porn. If you're that desperate, just skip to chapters 2 and 3. There's a lot more in this thing, but one of those should get you done. Day 15 has a more "normal encounter" if BDSM isn't your thing, and there's a few other encounters scattered throughout.

Inspired because I haven't seen Princess Twilight paired with EQG Sombra, even though there's a bunch of "Sombra captures Twilight" fics.

You're welcome.

Day 0, Morning

Princess Twilight Sparkle of Equestria smiles at Twilight Sparkle of Canterlot High. Their little exchanges are one of the highlights of Princess Twilight’s visits. She loves seeing how an alternate universe version of her could have learned and grown. But right now, she has something more pressing to manage than catching up with her doppelganger.

“Twilight! I’m sorry I don’t have time to catch up, but have you seen Sunset? I need to verify some anomalies with our journals.”

The other Twilight smiles back just as warmly. “Oh. I understand, Princess. You picked the right time. Sunset should be by any moment.” She gestures to the open courtyard in front of Canterlot high. Students are showing up, streaming in towards the building and mostly ignoring the duo.

While not all of them know the details, they know that “Twilight” is the magic girl, so they tend to ignore any oddities about her. Either of her.

Spike pokes his head out of Princess Twilight’s bag. “Hey, Twilight! How’s it going?”

Princess Twilight rolls her eyes as Spike jumps from the bag and Canterlot High Twilight picks him up with a squeal. “Spike! I love when you visit! Do you have time to meet with my Spike? He’s working at a movie set right now, but I’m sure he’d be happy to say hello! There aren’t many dogs around that can talk with him.”

Spike looks back at Princess Twilight with a whine. She sighs. “Fine… But you’ll be on your own! I didn’t tell anybody where I was going, and if I don’t show up to court on time, they’ll panic.”

Canterlot High Twilight raises Spike in the air with glee and does a twirl. “Yay! I love visits from Spike!”

Spike seems happy enough.

Princess Twilight can’t help but grin at how cheerful they seem. She should visit more often. It’s probably good for Spike’s ego to not be a prince for a while, and to just be a friend instead.

“Princess Twilight? I thought you’d be later?” Sunset’s voice calls from behind.

Princess Twilight whirls around to see her friends, well, her Canterlot High friends, all approaching in a group.

“Sunset! Girls! I’m glad to see you, and sorry to be rude, but I’m in a hurry. My morning schedule got moved forward and I don’t have time for a proper visit.” She looks down apologetically.

“Nothin to it!”

“Of course, your Majesty!”

“Just glad to see ya is all, Princess Twilight.”

“Awwww… I wanted you to stay!”

“It’s… nice to see you anyways.”

The girls each give her a hug while Sunset waits somewhat nervously to the side. Hugs are something she appreciates slightly more in human form. Pony hugs are great, but hooves don’t have the same reach as human arms and hands. Humans seem built for hugging, while ponies sort of… make it work.

But humans don’t nuzzle, which is something she awkwardly learned from Sunset, so on the whole it’s split fairly evenly.

Sunset coughs, interrupting. “Hey, uh, Princess… Sorry about your schedule. Is what you wrote true?”

The rest of the girls slip by Princess Twilight to greet Spike and Canterlot High Twilight, and maybe give her a little space with Sunset.

She nods. “I noticed the fluctuations two weeks ago, and I’ve been monitoring them. In some cases, the ink is fading, and in others it seems darker… almost black. I hate to ask you this, and please forgive me, but…”

Twilight lowers her volume while Sunset leans in curiously, “Have you… experienced any dark magic surges lately?”

Sunset’s eyes widen in surprise, then narrow almost angrily. Twilight winces as Sunset opens her mouth, but then the words that come out surprise her. Sunset almost sounds like she’s trying not to cry. “I haven’t. I’m sorry to make you think… that I…”

Twilight interrupts her. “No, stars, no. Nothing like that. I’m… just at a loss. They aren’t losing power, far from it, but they are definitely being influenced. And, well, you’re the only other… you know. And you’re with your book all the time.”

Sunset glares, looking slightly sad. “I see why you didn’t ask me through writing.”

Twilight puts her hand on her forehead, searching for the base of a horn that’s not there. “I just mean…”

Sunset sighs, then relaxes with a smile. “Look, I get it. It’s fine. No. I haven’t. But that means it’s something else. Any other ideas?”

Twilight grips where her horn should be. “I don’t know… The only other magic nearby is… the necklaces, maybe? But those are straight from harmony here, and not technically Equestrian.”

“Honestly, I don’t think I’m technically Equestrian anymore. And the books hardly are. So it could be something local. You brought it, right?”

Twilight nods. She didn’t have to. Sunset’s book would have been enough to run a test, but she had to be sure.

Sunset pulls out her book while Twilight pulls out hers. They look the same on the outside, but when they open them up, Twilight’s is marked with dark splotches of stained ink and faded text. Sunset grimaces when she sees it.

“Oh. That’s bad.”

Twilight nods. “I know.”

Pinkie pokes her head over Twilight’s shoulder in what should be an uncomfortable position. “What you doing?”

Sunset answers while Twilight thinks. “We’re comparing notes. We might need to run a little experiment…”

Canterlot High Twilight chimes in, “An experiment? I can help!”

Princess Twilight gently removes Pinkie’s head from her shoulder. “It’s nothing like that. Although, we could use some help. Do you girls mind letting me take a look at your necklaces real quick?”

Sunset adds, “Actually, can I see half of them? Like… Pinkie’s and Applejack’s plus mine would make half, and Princess here can hold the other half and see if, you know, one has an effect we can… reduce down to.”

Princess Twilight’s ears would perk up if they could. That’s a clever plan. Start with half on each side, each send a message, and then distribute the half that caused the issue until they narrow down the problem necklace.

Assuming there is a problem necklace.

The girls hand the necklaces out, and watch curiously.

Sunset makes a mark in her book while Twilight watches hers closely. The result is disappointing, but expected. The word “Hello?” appears, clean and sharp. Twilight frowns.

She begins to write her own, “Hello!” back.

As she writes, the word that Sunset had sent earlier begins to drip, smearing black ink and causing her to drop the book. “Ah!”

Sunset looks in surprise, then holds up her book. It’s equally stained. “Mine’s doing it, too. Weird.”

The sun seems to grow dim, and the clouds grow heavy. It doesn’t look like rain, but something about it feels unnatural. There’s a sense of foreboding wafting from the book, and Twilight is reluctant to pick it up.

Something is wrong.

“Sunset… Can you feel that?”

Sunset is still holding her book, but is looking at it curiously. “Wow… Eh… I see why you, uh… pinned me. This is…”

Twilight shivers. “I know.”

The clouds grow darker, and the dim light feels more oppressive. It’s not simple cloud cover. Twilight realizes it just in time to spin around and look.

There’s a black miasma rolling across the ground. It’s only hoof… ankle height, but it’s spreading fast.

Canterlot High Twilight looks at it curiously. “What’s this?” and she reaches down to touch it before anyone can act. She immediately falls over with a horrified look on her face. Spike lands in the mist, and shakes his head. He seems dizzy, but quickly grabs her by her coat collar and begins to drag her out of it.

Sunset speaks up in a panic. “It’s not the books, Twilight!”

Twilight grimaces, recognizing the smokey black cloud and the look of terror. She knows exactly what, or rather, who is to blame. Her voice is grave. “I know…”

In the center of the cloud, a tall figure takes shape.

“Stop this! Please.” Twilight glares at him, her frayed and somewhat scorched hair covering one of her eyes as she warily watches Sombra. Her hands squeeze the three necklaces in her fist—she can feel the last of their drained magic evaporate under her touch.

Sombra just grins. No answer. No words. Not even a glance towards the cowering students of Canterlot High. He already has the rest of their Equestrian artifacts—even Sunset and Twilight’s books. All she’s managed to save are Fluttershy, Rainbow, and Rarity’s necklaces, and only because she never let go. His smoke simply takes what it touches. She hates his smug, self satisfied face.

Her eyes flicker to the painfully battered body of Sunset Shimmer and the rest of her thankfully unconscious friends. Even the frozen and terrified face of her science obsessed doppelganger is mixed into the pile. Frustration clouds her mind. He’d crushed them immediately in the fight; the magic overload paralyzing the natural humans near instantly with fear. He’d had no mercy and no hesitation.

Only she and Sunset had been able to keep fighting after the initial attack, and Sunset had been quickly battered into unconsciousness the old fashioned way as smokey appendages punched her around like a plaything. Twilight had managed to last this long due to her alicorn magical resistance, the smoke had dissipated when it touched her, but he’d managed to land a few more traditional combat spells directly on her. She’d been kept mostly safe with the magic from the necklaces, but her last lifeline has just evaporated in her hands. The gems are empty.

Sombra’s grin widens as he finally speaks. His voice is unnervingly low, seeming to emanate from the shadowy mass on the ground and not from his body. “I haven’t killed anyone… yet. They’re bruised, battered, and maybe a little… broken. Otherwise they’re just unconscious. They’ll live for now.”

Twilight feels the three necklaces weigh heavily in her fist as she stares at him.

Does he know she’s completely out of magic? Her Sombra wouldn’t hesitate to kill them all if he sensed an advantage, especially over her. Maybe he’s paused his assault for a practical reason rather than some desire not to kill them. Maybe her power source isn’t the only one drained, and he doesn’t want to risk running completely empty.

She feels a ghost of a smile on her lips as her hope rekindles. If he’s as dry as her, there might be a chance—out of magic doesn’t have to mean out of options. “Hiding behind hostages? Is that all you have left, Sombra?”

He returns her smile, his unnaturally sharp teeth make her feel uneasy as he lifts the four necklaces he’s holding up in the air. His mouth doesn’t move as the sound of his voice resonates around her. “Not at all. This is mercy. I could crush them easily, but I don’t have to. These trinkets are curious. I’d even say powerful in their own right; but I don’t need them. I have plenty of my own power. Unlike you.”

She frowns and takes a step forward. She feels a pulse of magic emanate from him. He’s not out of magic. He’s not even close. As she looks at the necklaces he’s holding, she realizes they haven’t been used at all.

This shouldn’t be possible. Not here in the human world. Yet, the evidence is clear.

He’s been using his own power; and only his own power. It hadn’t even been a contest. He had taken them all out, overpowering them and stealing their necklaces with practically no effort.

Twilight bites her lip until it hurts. It hurts a lot more knowing how utterly powerless she is right now to stop him.

He raises an eyebrow as he stares right back at her. He frowns, seemingly surprised at some revelation, then smiles again. “I’ve changed my mind. Surrender. You’re coming with me, and in return I’ll leave these people alone. I’m only here for the trinkets anyways. Not their lives.”

She continues to bite her lip, her eyes searching for an option. Flash is standing in front of the crowd, placing his body between the battle and some of the younger students. Spike is behind him, having finally succumbed to the fear miasma with wide, terrified eyes and a paralyzed look.

A sad chuckle escapes her lips, and she only sees one option. With a snarl, she tosses the drained jewelry to the warlock. “Fine. Take them.”

Sombra catches them, and all seven disappear in a green flash—the same thing he did with the books. He frowns as he stares at her.

Twilight growls. “You won. Leave us like you promised!”

He continues to frown. “I required your surrender as well as the trinkets. You don’t belong here. I can sense it. The others have magic; the orange red one is even a fledgling sorceress. But you’re different. Natural magic has no effect on you, so therefore you are unnatural. Perhaps something not entirely human. You are coming with me.”

Twilight senses a magical construct; a spell forming above her. It’s hovering over the student body. The spell is formless now, but it could easily incinerate them. The arcane fire would be harmless to her, but to the humans of Canterlot High? They would have no idea until it was too late. Her eyes flicker to Flash. He’s shaking his head “no”. He also has no idea how close he is to being burned alive. She doesn’t know if Spike’s dog body is as fireproof as his dragon form, but she’s not about to find out.

It doesn’t matter. She knows Sombra will do it. In this world or the other, he’s ruthless.

Twilight raises her tired arms. They’re heavier than she remembered. “I surrender. But… only if you don’t hurt them. Please.”

He grins as the construct melts into harmless energy; a strange trick to Twilight’s senses. “Smart.”

With a wave of his hands, the energy coalesces into a green portal just in front of Twilight. His spell casting would be interesting to Twilight if she had the energy to care. Equestrians don’t recycle magic like that. There’s no need. Here on Earth, though, it almost seems a practical necessity. He probably doesn’t even realize that it’s strange to recycle spells.

His voice is demanding. “Now, step through.”

With a defeated sigh, she half-heartedly tries to memorize the clean spellwork he’d used to reform the spell. Maybe the skill will be useful later. She gives one sad glance at the terrified Spike, and nods toward her pile of beaten friends. Flash follows her eyes. “Take care of them, Flash. I guess I’ll see you later.”

Her last thought before she steps through the portal is that Flash is sort of cute when he’s panicked.
