Sunset Shimmer escapes Canterlot, but finds herself in the middle of a great conflict. It now falls upon her to protect the timeline of a world that went on without her.

Sunset Shimmer, in her thirst for power, goes through a mirror, a magic portal to other universes and dimensions.

But during her travel between worlds, someone crashes onto her and drags her out of the path laid in front of her.

Now she faces a conflict beyond her wildest dreams: to protect the timeline, the future of Equestria, from those that will stop at nothing to kill someone called Blazing Sun.

For the promise of power, the (arguably) greatest unicorn of her generation will face this new threat to the timeline, and prove herself superior.

Let's see if, along the way, she learns something about becoming a better person and whatnot.

My Little Pony belongs to Hasbro.

Inspired by the concept of Dragon Ball Xenoverse.

The Price of Ambition

Ambition can be a curious thing, guiding one to the most unexpected places. The promise of power and its pursuit is how most conceive this concept.

Ambition can be a good thing, if what you aim to be is something that can help others. But Sunset Shimmer's ambition had long ago walked down more selfish paths.

The student of the great Princess Celestia, a magical prodigy without equal in her generation; the study of the arcane arts and perfecting was all that she dreamed about.

Greatness was her destiny, and sadly she believed it too much.

Unknown to almost everyone, Celestia had subtly nudged the bloodlines of her subjects, in the hopes of creating powerful ponies that her teachings would make heroes. Protectors of Equestria.

Out of love and concern for those that were under her watch, all too conscious of the dangers of the world... and to, hopefully, create the next generation of Bearers of the Elements, and wield the power of Harmony to succeed where she failed and save Luna.

Sunset was one such pony, and her potential was endless. But the unicorn, while she ignored the reason of her power, knew that she would always be in the shadow of Celestia. For the alicorn had the best of the three main kinds of ponies, and had cultivated those traits to their peak.

But the greatest student of the alicorn princess refused to be less than her teacher; out of pride and love, she wanted to be at her side. As her equal. And all the talks and subtle nudges to make friends didn't deter her ambition, for the unicorn didn't know of the power such bonds could bring, both metaphorically and literally.

Celestia, a flawed person as everyone was, didn't realize she should have been more direct in making Sunset understand the importance of friendship; but having to plan and act in secret for so long led her to overestimate her student. She wouldn't open to others, and that mirror sealed her fate.

Maybe, had the princess acted otherwise, her pupil and currently best hope to save her sister would not have escaped through the mirror portal.

But that's not the possibility this story will explore.

Disappointment was something Celestia was used to feeling. Sadness? Oh, even more.

Sunset Shimmer had been a failure, and now she had run away, just as the portal closed; now it was too small and unstable to go through and find her. The little pony she had taken under her wing and trained for a great destiny, so sure she was the one needed...

Gone.

And the feeling that it was her fault, at least in part, eclipsed everything else. And even that was replaced with alarm as she watched the mirror, energy unlike anything she had sensed before emanating from it.

Before she could use a spell or give an order to her equally alarmed guards, the mirror exploded, magic and energy throwing them against the walls as power washed over them and tore the room apart.

As soon as it started, the blast of power ended.

Celestia got back to her hooves among groans of pain, the explosion leaving bruises in more than one place. As her guards tried to recover and a few more entered in an frenetic order, the alicorn despaired as her eyes fell over the remnants of the mirror.

The device was gone, the portal now a mere wound in the universe that trembled in a barely audible sceam before collapsing on itself, forever closing.

Sunset... no...

And for years the alicorn would pray, not caring what great deity or power bothered to listen as long as Sunset had managed to get to the other side before that explosion.

Sunset didn't know what to expect as the whirlwind of magic dragged her towards a light shining at the end, spells filling her and changing her in something she couldn't stop, her own magic too stretched to fight back.

Then something hit her on the side, and the whirlwind seemed to shift.

Whatever was left of her senses looked at what, by instinct, had grabbed her, pain giving way to confusion in the eyes that seemed to look right into her soul.

Two burning powers crashed through the whirlwind of spells, one dragging the other in search of its prey, not realizing they had stumbled upon someone else and colliding with Sunset and the mysterious being.

Some sort of dimensional inertia or impulse pushed the group out of the bridge the portal had created between the worlds, and the future collapsed.

All that Sunset was going to be, all the bonds that would have been created and nurtured on Earth, the magic that would flow into the world that expected her beyond the light, it was possibility that had become certainty... only to find itself denied just a few seconds before happening.

All of that collapsed, untolds amounts of energy suddenly filling the point of change, and the bridge could not handle it. Magic, energy, temporal power and more destroyed the portal, most of it dispersing between Arcana Magna and the Earth, only a fraction escaping through the ends of the connection before said connection found itself obliterated.

And the waves of energy pushed the surprised four beyond the timeline.

Agony filled the unicorn as the spells within her body twisted and shattered, the fragments tearing her flesh, bones and soul apart, her magic unconsciously fighting back. Pulled and pushed in every direction as every spark of arcane power that she called her own kept her together without retreating an inch, her eyes looking without seeing the wonders of time that filled and surrounded the multiverse like an ocean.

Whoever was holding her managed to right themselves and swam through the time, too busy looking for a calm place in the middle of this ocean while fighting with their other passenger to realize they were bringing the shattered unicorn with them. The relentless pursuer kept hitting his current ride while keeping the fourth being in as close of a chokehold as it was possible in their current, mostly immaterial state.

After eternities that barely filled seconds, they reached an island, catapulting out of the water and crashing on sand, the barely material beings rolling in different directions.

The pursuer shone in bright gold, chronal power enveloping the four and forcing their energy selves return to physical form. An hippogriff stood menacingly in their place, glaring at the two dragons she had been pursuing. As the two reptiles got up, spitting sand and returning the glare, a horrible cough caught their attention.

All three looked to the side and were taken aback at the sight of Sunset Shimmer, magic of every color coming off her body in waves as she coughed blood and fragments of spells, the arcane power vanishing against the sand. Bloody eyes tried to focus on the fight that had stumbled upon her, horn charging magic by instinct before losing power.

A veritable pile of sand was thrown at the hippogriff, the dragons taking advantage that she was distracted before jumping back into the ocean of time. By the time the Chronos Warrior got out, they were long gone.

River cursed her luck at her targets escaping yet again before Sunset's heavy, bloody coughing drew her eyes back to the unicorn. Sunset collapsed as the hippogriff walked to her side.

She talked, but Sunset's hearing wasn't working, and even if it was, she wouldn't have had the chance to answer whatever question River made as she passed out, her mind finally giving up in trying to stay conscious.

Author's Note

When I first heard about Equestria Girls, I found the concept to be a stupid addition to the MLP franchise. The typical high school setting, throwing magic to it? In the moment, I didn't like it.

I did like Sunset Shimmer's character, and found the second movie enjoyable. I ended up with mixed feelings regarding Equestria Girls.

But hey, this is fanfiction, where imagination is the limit! I've seen alternate takes of Sunset Shimmer's life where she never went to the human world, my favorite being The Witch Of The Everfree. So why not make mine?

This is what came to my head, inspired by Dragon Ball Xenoverse. I haven't played the game, but enough people have uploaded videos on Youtube to sate my curiosity on it.

Let's find out what awaits Sunset now that her future has literally blown apart, and see if she can learn to be a better person without a rainbow of arcane power shot at her very being.

Oh, and if you wonder what will happen on the human world without Sunset, check this story: Kamen Rider: A Shift in Time.

... What? I like Kamen Rider.

River and Chronicle

Sunset Shimmer knew pain very well. One didn't go as far as her in the quest for mastery of the arcane arts without accidents and failed spells backfiring on the caster. It hurt her pride to admit it, but while these happened less as the years passed and her skill and knowledge grew, they never stopped. Not even she was infallible.

But not even all those incidents together could compare at the torture her body had been put through, pulled into so many directions at once as broken spells stabbed into her body and mind that it was a miracle she wasn't dead already.

As her mind succumbed to the agony, Sunset found herself floating in a void, sometimes colorless, sometimes filled with a myriad of colors, wandering aimlessly and without control. The pain was now barely more than a faint buzzing in all of her being.

She briefly wondered if she was dying, and an eternal instant was spent ruminating about why she didn't care.

Where was all the ambition that had pushed her forward, the pride that pushed her to be perfect? Her desire to trascend all that she was and reach her true potential? All the anger at failing?

Did she not care that she wouldn't see Celestia again, proving herself worthy of standing at her side? That she would never be at her side?

Doing more than just exist is tiring. Feeling is tiring. I just want to rest. To close my eyes and sleep...

Something in her didn't like that thought as whatever was left of her power stirred, surging from her body as a bit of feeling returned to the pony.

Sparks of teal magic danced around her, exhausted but unwilling to leave the unicorn. Sunset and her arcane power were tied to each other in ways a being without it would never understand, and at least the magic still desired to live. The burning ambition that was Sunset's main drive was practically imbued on it, and so it was as passionate as her.

The unicorn smiled at the only thing in her life that would never leave her, embracing the biggest spark and keeping it close to her heart, her mind content with watching the rest dance. If being alive meant staying together with her magic...

Then she would stay awake.

A second of eternity passed before she noticed the colors around her growing in intensity, flowing in all directions and taking blurry shapes, like seeing at the world without glasses. Bipedal beings walked and ran all around her, their indecipherable chatting and laughing and crying not louder than a whisper.

A white figure rose at her side, more clear than the others. The statue of a horse stood proudly before dissolving, the dust forming a guitar that seemed to be made for her if the color scheme was any indication. Warily, Sunset extended her foreleg and touched it with a hoof, feeling a powerful and energetic melody fill her, the sparks of magic dancing with delight. It was good music.

The guitar vanished, leaving Sunset and her magic disappointed. Then the void trembled for an instant, and both were taken aback as something new appeared before them. Something very powerful.

A purple star shone in the void, the promise of the power and future Sunset coveted so much woven into its light. She stretched a hoof slowly, sparks circling around the foreleg to offer their support. While before this experience she would have jumped at the chance being offered before her, grabbing the star in an instant and tearing through anyone in her way, now she could barely muster up enough desire, enough longing for that dream to just reach for it.

As she touched the star, it shone brighter in anger, magic black as night surging from it.

"This is what you desire?! You are not ready for this power! But if you don't believe me, then take it anyway. Let it consume you until there is nothing left of Sunset Shimmer."

The star's magic surged through her hoof, the entire limb morphing into a fiery claw, hotter than any flame and sharper than any weapon. Sunset could only stare, too exhausted to feel shocked but not too tired to not grow afraid.

Her magic recoiled as the dark power embraced her, leathery wings that shone in red and black spreading from her back, power unlike any other burning inside her soul.

Her sparks of teal magic moved around her, nervous and uncertain of what was happening.

Sunset felt the power grow to equal, then surpass Celestia's, that new magic growling like a feral beast and ready to tear through anyone that stood on her way. It was unstoppable, and now Sunset Shimmer herself was unstoppable, having gone beyond her potential and become something more.

Something implacable, merciless and vengeful.

Something that was nothing like the Celestia Sunset admired and envied.

The unicorn stared at her claw, somehow knowing how easy it would be to cut someone to pieces with it. This was not what she wanted.

This just felt... wrong!

The star's anger faded, leaving behind only sadness at the sight of what it had created. "Oh... Oh, I'm so sorry. But you wouldn't listen..."

Something warm and gentle touched her claw, the fiery appendage dimming down to a weak flame. Her limb went back to normal as it moved along to rest on her shoulder, calming the beast that seemed to now linger within her.

Looking to her side, Sunset's eyes fell over a small, golden creature shaped like a teardrop, the point extending like a long tail while two shorter tentacles extended from their side. One of them was the thing resting on her shoulder. Two green eyes filled with both kindness and sadness stared at her own.

"This is no longer your path, Sunset Shimmer," It-no, she spoke as the blurry shapes and the star dissolved into dust, floating away.

Sunset turned to face her as the other tentacle fell over the hoof in her chest that still held the spark of magic in a hug, all the others moving around this new being, wary yet curious.

The dark power faded in front of her touch, the wings blazing once before vanishing in a white light.

"I'm afraid that the future you saw is no longer yours; and I can't change that," she said as warmth filled the emptiness that dark power had left behind, the sparks of magic shining brighter as vitality returned to her; the faint pain she still felt was soothed. "But I can promise you this: you will have a future."

The tentacle in her shoulder went further up, gently caressing the unicorn's cheek. "Now it is time to wake up."

With a groan, Sunset rolled on the bed she was resting over, hugging the pillow like it was a lifeline. She had never felt more exhausted in her life; her body didn't ache anymore, but it felt so drained of energy that she wouldn't be surprised if she were to sleep for a month.

Dragons could sleep for decades, and now Sunset wanted to follow their example. It couldn't be too hard; she just had to ignore everything around her.

Ignoring explosions is hard, though.

BOOOOM!

Something exploded in a near room, shaking the entire building and causing Sunset to jump off the bed and all the way to the roof, failing to find something to grab and falling to the floor.

THUD!

Adding pain to the utter exhaustion of her body, the unicorn was left moaning in the middle of the room, doing her best to not whimper as shouts filled the house.

"WHAT THE HECK WAS THAT?!"

"HOW SHOULD I KNOW?"

"IT WAS YOUR INVENTION THAT JUST BLEW UP ON OUR FACES!!"

"FOR CHECKING ON YOUR DISASTER!!"

"OH NO, YOU ARE NOT BLAMING THAT ON ME, TURNER!"

"YOU MAKE A CHANGE IN THE TIMELINE AND WE FIND AN EXPLOSION IN ITS PLACE?! I'M DEFINITELY BLAMING YOU, RIVER!"

Something fell over, starting a chanin reaction that ended in many slams and broken glasses.

"And there goes half of my lab! I'm sending you the bill for that!"

"Don't be a crybaby, Turner!" There was a hum, and what could only be described as the sound of the long crash going in reverse filled the air for a few seconds. "There! Good as new."

The female voice had barely finished when the crash ocurred again; Sunset would have rolled her eyes at what she deduced was an epic failure, if she wasn't using all of her energy to try and climb back to the comfy bed.

"..."

"..."

"... remind me again why they promoted you to Chronos Warrior?"

"@%&$* you, Turner."

Sunset Shimmer let herself fall on the bed, coughing a couple of times before speaking as loud as her dry throat let her, "A-are you two done making a mess, or should I look for a place less prone to explosions?"

Silence reigned for a moment before hurried steps and whispers reached her ears; a minute later, the door opened. A brown earth pony entered carrying a jar filled with water and a glass over a platter, followed behind by a hippogriff.

Sunset had never seen one in person, but she couldn't bring herself to do more than stare before the pony settled the platter on the nightstand, turning to her with a kind smile.

"Hello; my name is Time Turner. Nice to meet you, even if the situation is not ideal."

"... Sunset Shimmer," The unicorn greeted after a few seconds, tired yet wary. They seem to be taking care of her, but she didn't know who they were, or where she was.

Turner's smile grew a little before gesturing to the hippogriff. "She is River, and I'm sorry you had the displeasure of meeting her."

The pony ignored the glare and rude gestures of the hippogriff, thought his smile grew a bit mischievous as Sunset coughed a laugh. "How do you feel?" He asked gently.

"Exhausted. In pain. Exhausted. Sleepy. And exhausted. Not to mention exhausted." She turned to the hippogriff. "Thanks for that, by the way."

The hippogriff shrugged, "Not my fault you got in the way."

"River..." Turner warned as he filled the glass.

"What? I was just doing my job, and thanks to her those two escaped. Again!"

Turner bit his tongue so he wouldn't comment about that last part and start another argument. He offered the glass to Sunset; the unicorn tried to summon her magic, only getting a few sparks before giving up and holding it with her hooves.

"An unicorn not using their horn for something? Now I've seen it all," River quipped, trying to lighten the mood. The glares she got from the ponies were a clear sign that it wasn't working. Throwing up her claws in surrender, she stepped to the side and laid on the wall.

Sunset drank slowly, her throat having difficulty with even this small amount of liquid before coughing up multicolored sparks, Turner and River barely avoiding the fragments of spells that shot through the room, crashing against the wall before dissipating.

"I thought dragons were the ones that spit magic," The hippogriff grumbled, rubbing a burned feather in her wing.

"That's not normal..." Turner mused.

The unicorn sat up, suddenly feeling a warmth in her chest, expanding and pulsing. "Uh, this doesn't feel normal either..."

A flame ignited in her chest, a bright golden that surged from her fur. It wasn't painful, or even uncomfortable. Little by little, the fire flowed out of her before shifting in the air, a teardrop with tentacles forming in front of them. Green eyes opening as the time creature regarded the group.

Sunset stared at her, jaw practically on the ground, while Turner gave her a nod as greeting. River gently massaged her eyes before speaking.

"So, what happened, Tic Tac? I had never seen anything like that."

Turner facehoofed as the time creature twirled in the air, light swirling around her form before settling, revealing an exact copy of River that was looking at the original with annoyance.

"My name is not Tic Tac. Chronicle is the name you may use to refer to me." She said with the tiredness of someone that had gone over the same issue hundreds of times.

Though she now was a hippogriff, her voice was just as powerful as when helping Sunset in that strange void.

The unicorn's brain worked feverously to try and understand what she was seeing, coming up with an elegant and extensive inquiry to direct to the earth pony.

"What?"

Well, it obviously got lost in the way, leaving Sunset's mouth to improvise. At least it got the message across.

Turner rubbed his head, seeing how utterly exhausted the unicorn looked, "It's a long story; we should wait until you are rested. No offense, but you look like you could sleep for a century."

Whatever protest Sunset had didn't finish forming as her exhaustion grew with every minute she spent awake. "I feel like I could sleep for two centuries."

Chronicle turned to River. "You crashed on her just as she was crossing between worlds, several transformation spells turning her into another species to blend in with the inhabitants on the other side. Your interference caused the future she would have had there to collapse right in the bridge between universes, all the potential energy burning itself."

Turner facehoofed as River groaned, cursing her luck. Sunset wasn't sure she understood all of it, and she wasn't precisely in the best of conditions to form her own conclusions.

Chronicle walked towards the bed, stopping just in front of Sunset. "I have fixed most of your physical damage, and your body can handle the rest; but you need to rest. You were pushed to the limit, and yet, you refused to succumb. You have earned the time to recover." She lifted a claw and, with some hesitation, rested it on the unicorn's shoulder. " Like I promised, you will have a future."

Sunset looked at the claw for a few seconds. After some internal debate, she swallowed her pride. She was too tired, and Chronicle had saved her life. If anything, this was the very least she had to do.

"Thank you."

The words were strange as they left her mouth, like her tongue had forgotten their taste when they were sincere. Now that I think about it... When was the last time I said 'thank you'?

Chronicle nodded, her eyes as gentle as the first time Sunset saw them.

The unicorn gave up musing about everything that was happening- sudden, if little moral dilemmas and strange creatures that could shapeshift included- and laid down, getting comfortable in the bed and closing her eyes.

"I'm going to sleep. Try not to blow up the house again before I get my answers."

"Whatever you say, Princess." River rolled her eyes and left the room, not noticing Sunset tensing before her exhaustion won over and she fell asleep again.

Turner raised an eyebrow at Chronicle in a silent question, but she shook her head; it was not her place to answer. Turning around, the two of them followed River as quietly as possible.

Author's Note

Not much to tell here; I'm trying to not let myself lose this inspiration to keep writing, as I seem to be making at least one chapter every week. Let's see for how long I can keep it up.

This chapter has a sort of prologue in Chaos in the World of Order. It will be up soon, as I'm running out of vacation days.
