A suit of armour wakes up in the woods from a very long nap and has some issues. These involve some less than stable quadrupeds called ponies and one very specific one which we shall refer to as Luna.

My name is Rachel. Or at least it was. A bad decision brought me to the brink of death. I was "rescued" from that fate by some self-appointed "Spirit of Chaos." Or maybe he really was the devil, I don't know. He promised me a second chance but didn't tell me it would be in the body of a cutesy pony in a world which makes no sense. Worse, I think I've been set up, and something bigger is going on ...

A young girl, having been robbed of her childhood and very life by illness finds herself given a second chance in a strange world and with an even stranger body. With a new life, family, and even a brother, she tries to cope with the bizarre world she's found herself in while also trying to embrace her role and become worthy of the gift she has been given.
Being a princess can be hard however, even if it's only an honorary title, especially when you're the twin sister of Prince Blueblood.

Warning, very slow burn.

Amanda was never a very popular girl. She was always too strange, too eccentric, and her obsession with a TV show from years ago certainly didn't help. She lived a fairly bland, lonely life, but she never would have said she was unhappy if you asked her.

That all changes when she wakes up to find herself transported into that very TV show. And she's not just in Equestria; She's at the start of it all, the very first episode. Knowing she can't afford to let the opportunity pass, she leaps into action, ready to join the adventure and help the Mane 6 along their journey!

Things rarely go so neatly, though, and before she can even meet Twilight, she runs into a pony who, by all accounts, shouldn't be there. Trixie is in Ponyville, and she can't believe what she's hearing. The story is just too unbelievable.

How could she be a villain?

Sucked into a reluctant alliance, Amanda—now a pony going by Starfall Sage—must try to steer Trixie towards a good ending, but as she'll discover, that's a lot easier said than done.

This isn't where I belong. I left all this behind years ago, moved on with my life. But a mare from my past brought me back, and now she won't let me go. So I'm stuck here, trying to make the best of it with ponies that don't understand me, don't even like me. But when something moves in the darkness, and when things go wrong in the cold, dead night, they'll turn to me to try to set things right.

Why? Because once a police pony, always a police pony.

This is a spin-off story to 'Why am I Pinkie Pie?!', and will contain spoilers for that story, but it's not necessary to read that story to understand this one.

There is now a side-story: A Hard Day's Nightmare Night

Okay, I don't know if anyone can hear this, or read this, or whatever, but I'm trying my best to use Pinkie Pie's legendary fourth-wall-breaking powers to try and get a message out.

If you can hear this, I need help. I'm in Equestria, and man, this is strange. But I'm also stuck in Pinkie Pie's body, for some reason.

Yes, it's just as weird as it sounds. And now, I need your help... because all the ponies in this town think I'm crazy!

This is the story of a brony, who inserted into Equestria.
But instead of a pony, he became the enemy of Celestia.

Would he decide to do what’s right, to love and tolerate
Or would his evil changeling nature make it hard to integrate

Then there is the question of the duty that is his natural birthright
Tasked by the changeling Queen, he was to murder Princess Twilight

So, here’s my attempt at a SI with a bit of a twist that others have done before. Go to Equestria, end up on the wrong side of the tracks, and have to deal with it. Enjoy!

To be inserted into Equestria, it's a dream come true for anybrony!

Meet the ponies!

Have super awesome magical adventures!

Use foreknowledge to avoid all those silly pratfall moments without screwing things up and causing irreparable harm to the Mane 6...uh...hopefully!

And all for the low cost of possessing Princess Luna, denying her any real freedom or the ability to move on with her life since she's in your head and you're walking around as Nightmare Moon!

Yeah...there had to be a catch in there somewhere, didn't there?

I woke up in the hospital. I don’t recall how I got here. I don’t recognize the mare who says she’s family. I don’t even remember my own name.

So what kind of pony will I become?

Apple Bloom has a very important classroom duty, at least according to Miss Cheerilee.
