When the rebellious and power-hungry Sunset Shimmer steps through Canterlot's magic mirror, she enters a world that is more... unforgiving than the EQG-verse we are used to. One completely devoid of magic.
Very quickly, she is humbled by force, and eventually finds herself living on the streets, begging for scraps from unkind strangers, just as winter is around the corner.
That is, until she meets Anon.

Originally written in 2014 on /mlp/.

War is a rare occurrence in Equestria, but after over a century of peace, it has come again. To defend their home, ponies have answered the call to arms from far and wide. For one young pony, that decision may have come a little too easily. Will the weight of war prove too much for her, or will her new found comrades be the foundation she needs?

I wish I had posted this earlier, but here is an incomplete visual list of the characters of The Line. For the characters not listed here, please consult the cover image.
You can also find a depiction of the standard armor suit here.

Celestia, the most noble of entities. Filled with love and compassion. Powerful, wise, immortal.

Lonely, sad, and wracked with guilt at her failures.

Come, reader, and learn the story of the magnificent Princess of the Day. Part of it, at least, for the story of an immortal must be without end. Only part of it, but enough to see who she is, and what she longs for.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

This story is a sequel to Fashion Crush

(Humanized) Vincenza Scratch, AkA Vinyl for her friends, AKA DJ-PON3 on stage, 22 years old. The DJ found herself in one of the low periods of her young career, probably the lowest and longest she ever experienced so far; writer's block, out of ideas for a new genre of music as her 'classic' electronica seems to go out of the crowd fashion, less and less attendance to her gigs, etc.

Starting to run low on money, She gets in touch with one of her mother's friend in the capital, Vito Philharmonica; Member of the board of one of the most prestigious private high school. Vito offers her a place to stay and a job to help her to get back on track : A music teacher job for a Highschool senior class, which includes Vito's own daughter, Octavia.

How's Vinyl going to teach to a bunch of teenagers when she's barely older than them? ( and probably not much more mature as well). And when other teachers and some of her students look down at her for being a 'simple' DJ? One answer, Becoming the GTVS: THE GREAT TEACHER VINYL SCRATCH! (Yes inspired by GTO, one of the coolest manga ever)

Don't forget to check the comic version as well

Twilight Sparkle is a happy pony. With the help of her friends she defeated Tirek. She has a shiny new castle, the kingdom is safe, and she knows the reason behind her ascension. What more could a young princess want?

She is happy, she tells herself as she digs through the ruins of her home. She is so happy she can barely smell the ashes any more.

But in those ashes she finds something unexpected: a small porcelain vase, and with it a decade's worth of unspoken questions. A mystery hiding beneath her hooves, waiting to be put to rest.

Winner of the November Writeoff event.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

During a traumatic event, an outsider finds himself flung violently into Equestria. His physical form is warped into that of the inhabitants but will his mentality follow? And even more importantly, will anypony truly accept him for who he is? Take a journey alongside this inexperienced youth as he finds himself in a strange new world with very different customs and tries his hardest to find a place for himself where he didn't before. A pity he can't even remember his name...

Okay, the basics. It's first person almost entirely. Very, very long chapters. I try to wrap them up around twelve to thirteen pages but a few slipped over that, especially towards the end. I'll release them slightly stagnated, as I'll be making final revisions as I go. Character tags are NOT final. I'll add more main characters as they show up in each chapter. Expect an update one or two times a week, probably. I adore reviews and structured, constructive criticism. Even if you just want to say you like it, that's fine too. :) I write stories to entertain peoples, so any evidence I get that it's working will encourage me. I hope you enjoy the story!

This story is a sequel to Memory Pending

The story of Moon Mender continues after his dream of an ending ceases. He continues his struggle to belong in a world so far divorced from the only other experience he can remember, but as an outsider of truly alien mindset, will he ever be able to find a place in Equestria? More importantly, will the life he left behind give up on its death grip so easily? The most important thing to remember is that things are rarely as they seem and sometimes, some things are better off forgotten.

This story is a direct sequel to Memory Pending. Without having read that, this story might be a little strange to most, which is frightening considering how strange it is already. It can be read as a standalone story of course, but you won't get the most out of it.

Further, I’m fully aware that not everypony enjoys more mature themes, so any scenes containing things of an M rated nature shall only be released in a separate story when the time comes. This story deals with more mature themes on a whole, as a warning. This version will do its best to censor the really sensual or graphic content out, of course.

Last but not least, this story has reached this final format through combined efforts of not just myself, but many a helpful pony along the way! Here’s an abbreviated list of those involved and the rolls they played:
Kiroberos – Author (Obviously)
Julia – Editor (Corrections, Grammar, and Flow)
Azu – Beta Reader (Corrections, Flow) (Until Chapter 35)
ExplosiveBrohoof – Beta Reader (Grammar) (Until Chapter 22)
Muffinking – Beta Reader (Corrections, Grammar) (Until Chapter 22)
All of my readers for being amazing, supportive, and best of all, enjoying the world we read and write about.
