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.

Rainbow Dash's morning was pretty much ruined.
She tripped getting out of bed and landed flat on her face, giving herself an aching muzzle.
She forgot to buy her favorite brand of hay flakes at the store yesterday and had to eat plain toast for breakfast.
She found out she had to pull double-duty today and tomorrow on the weather patrol.
Oh, and she found a nearly-dead foal, broken and bleeding at the edge of Ponyville.

The rest of her day became a whirlpool of stress and worry but the colt woke up, thank Celestia.
Something's not right, though. Nopony can find his parents, he's not in the registers, and there's an unsettling look in his eye...

TV Tropes page, if you're interested in that sort of thing.

Spike is depressed, and none of his old friends know what to do, let alone how to help him.

But maybe a new friend does.

[rated teen for talk about depression and suicide]

When I agreed to be sent to Equestria I didn't read the fine print. I'm the wrong age, the wrong sex, and lost in the wilderness.

New Cover art commissioned from Lunar Froxy.

When Fluttershy finds a human in her backyard trying to eat one of her chickens, she and a majority of the residents of Ponyville only want this dangerous creature as far away from their town as possible.

After a less than stellar first impression, Derpy Hooves and the human struggle to quell the rumors surrounding his diet, and convince the townsfolk that he's harmless.

Will the human be able to make himself meek enough to coexist? Or will he be driven out of town with torches and pitchforks?

Each chapter is told from the perspective of a different pony.

A suicide right by the school of friendship.
Why would someone do that when there was help so close?
Twilight can't let this go as just a tragic incident. There has to be a reason.
*UPDATED*
I just added some detail and fixed a couple small problems. The story itself is unchanged.

This story is a sequel to Equestrian Border Checkpoint

Hi, I’m Anon. I’m the asshole in the booth at the Checkpoint. See, ever since I came to the Equestrian Border Checkpoint of Manehatten, I’ve done two things. Stamp papers, and yell at people. I do both of these things really well. Now, without further ado, get your shit and get out, you’re holding up the line.

Papers Please does NOT belong to me, but there isn’t a tag for it. Sex tag is for references to sex. Also, there’s a shizzle ton of swear words. It get heckin hectic.

Chapters 1-14: The Human Arc
Chapters 15-28: The War Arc

Celestia has a dangerous creature held in the deepest of Canterlot's high-security dungeons. It can create ponies (with full backgrounds and histories) with it's strange and often-times prophetic powers. The Princess does her best to keep it under wraps, but its only a matter of time before it's "creativity" will get out of control.

Caramel decides to take Anon out drinking. It doesn't quite work out. A bittersweet look at a more grounded RGRE.

{This story has two versions, the last chapter is the first person version.}

Fifty years ago today, there was not a war. It was not one of the longest and bloodiest struggles ever known to ponykind. It did not claim the lives of hundreds upon thousands of ponies.

There is no such place as Shetland. It could not have been Ground Zero for Operation Petrichor because it never existed.

The Cloudsdale Massacre is a cheap horror flick, nothing more. Chemistry has no solid application in combat. The Non Sunt Dii has not existed since the first days of the Royal Sisters' reign.

Celestia is perfect. Celestia has never made mistakes. Celestia is not a coward.
