Tanya Degurechaff gets tossed into Equestria and transformed into a Changeling Queen. It's a nice retirement from modern warfare as an aerial mage. Then Queen Chrysalis attacks and forces her out of retirement. Historians refer to this as 'a bit of an oopsie.'

Marianne Evergold is a kind-hearted girl with strange tastes, for she's the only person she knows whose favorite character is... Diamond Tiara. Snotty, bratty, childish, and vain? Perhaps. But she adored her all the same. The confidence with which Tiara carried herself was something she never had. In her eyes, Tiara was truly graceful and picturesque. And while she understood that drama needed a conspirator and Tiara was just the natural calling card for the show's writers, she never liked the idea that she was truly evil. So when the show ended its last season with her being turned to stone for her years of villainy and almost bringing Equestria to ruin... Mary could not accept it.

The only thing she could never understand was... why did they never give her a proper redemption? It always felt like they would. Yet they never did. And if by some miracle they ever did, she would never get to see it.

For she finds she awakes one day in the lands of the colorful Equestria. Far from home. So very far from friends. And so, so very far from family.

And in the horseshoes of Diamond Tiara herself, no less.

But at least she has a goal now. To save Tiara from that fate. Already with a history of bad blood halfway into the show, it would be no easy feat to redeem her as no one would allow her the opportunity after many years of treachery. But Mary vowed to never give up on Diamond Tiara and would keep to her promise come what may.

All while Tiara herself sat back silently in her mind, sealed from being able to take control of her own body again and watching it all unfold.

This story is a sequel to Emerald Gleaner: Retired Monster

[Prototype 2] X MLP:FiM Crossover

Beset by a mountains of work both official and secret, Emerald has barely time left to herself anymore. Can one still become exhausted even if they physically can't? When does paranoia do more harm than good?

When people stop trying to kill you of course!

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...

This story is a sequel to Bed Bug

It was two months ago that you and Chrysalis struck a deal. Now, the two of you live together in your Ponyville home, under the condition that you share your love with the ex-queen while she... doesn't do villain stuff. You've grown quite close in that time, but despite getting her to slowly come out of her shell around you, she still refuses to leave the house.

So when you wake up one day to discover that she has contracted some sort of illness, it comes as a bit of a shock. She has apparently never been sick before, and you don't know enough about changelings to help her yourself. It seems like the only solution is to find somecreature who does.

However, the past is not so easily forgotten. How can you get help when the Changeling Kingdom wants nothing to do with her? When the wounds that she caused run so deep that even children bear their scars? When Chrysalis herself is so stubborn, so prideful, that she is unwilling to admit her fault in any of it?

When is a crime too terrible to forgive?

For a human that ended up in an alien world full of talking ponies, you've been living a surprisingly boring life. Sure, you have friends and go on adventures and stuff, but you don't really have a "purpose" per se. At least, you didn't until about a month ago, when a "heinous villain" that had been turned to stone went missing from Canterlot. Now, there's a washed-up queen crashing in your basement and stealing your love.

If only you could get her to admit that she doesn't actually steal it from you.

After a strange alien creature named Anon suddenly showed up in Equestria, it was only natural that Twilight Sparkle would want to help him adjust to his new environment. To do so, she enlists the help of local school teacher Ms. Cheerilee. With her guidance, Anon should be able to learn how to do things the "pony way," and before he knows it, he'll be another friendly face in Ponyville's growing community.

Unfortunately, Cheerilee isn't exactly a fan of the new human in town, nor is said human particularly happy to be under the tutelage of an elementary school teacher.

Is there any hope of them getting along?

I got dragged to Equestria by pure accident due to an experiment gone 'wrong', roughly forty years before Nightmare Moons' arrival.
No matter what I do, as a pony-changeling hybrid, something will change with Equestria. I just hope I don't doom the country before Nightmare Moon even arrives... Or worse.

This is the first story I ever tried to write professionally, so there WILL be errors, for that, I apologize in advance.
I'm editing and proofreading it on my own because I literally suck when it comes to using this site competently.
Lastly, I am a slow writer due to IRL getting in the way but I will try my hardest to settle the story down whether it's popular or not.

Fair warning, there may be spoilers in the comments.

Thank you to Little Tigress for the fantastic cover art.

On Flurry Heart's twelfth birthday, Cadance tells her daughter she will never die.

Haunted by the loneliness of her young immortality, Flurry Heart finds unexpected solace in the only other pony who could possibly understand her — the filly preserved for eternity within the Gardens of Canterlot.

Flurry could not have forseen that an apparition of that filly would appear before her, and only her.

Something brought them together. Flurry intends to uncover what.

Prince Blueblood is many things.

He's a Unicorn, He's royalty, He's a stallion, He's entitled, He's high-class, And most importantly he's not here right now.

If Blueblood isn't here right now, then who's that?

Well, That's Blueblood, the new Blueblood that is, a human in the body of Blueblood.

What will follow the actions of the new prince can be nothing short of disastrous.

Warning, this story contains Jokes, Magical Politics, a human-turned pony who doesn't know about MLP, Prince Blueblood doing Blueblood things, "Wine-Moms", and a very large sum of money.
You have been warned.
