In a world just a mirror-leap away from Equestria, a human Sour Grapes is a teacher and a boarding house landlord. She ends up dealing with both apathetic students and quirky tenants, but she's still the same Grapes with the same snark, but you get to see her as a history teacher in Canterlot High.

Will her unique perspective get the normally disinterested students to pay attention? Will she make it past her internship and become a salaried teacher? Will she go out on a date with that rather hunky dance instructor the school has just hired?

I suppose we shall find out, as the story unfolds.

Twilight Sparkle conducts an experiment and succeeds in obtaining an unusual flower with some intriguing properties.

What it could teach her, however, might prove to be more than she bargained for. She finds herself having to face surprising—and maybe frightening—new possibilities about the universe. How does it work? What is 'real', exactly? And why are these suddenly such uncomfortable and challenging questions for her?

Pre-reading and editing for this story was done by Grand Moff Pony, The Dobermans, SIGAWESOME, Reese, Georg, LCranston, and Equestria Daily pre-readers 63.546 and Slorg. Many thanks to all of them for helping this get where it is!

Sunset Shimmer is having the worst day of her life. She used to be important. She was the personal student of Princess Celestia. She was a future leader of Equestria. She was the kind of mare that everypony envied.

Today, it's all crashing down around her.

Alternate Universe: What if Sunset Shimmer hadn't gone through the mirror?

Crime was easy before Princess Twilight and the First Five ushered in a golden age of Harmony. Back then, any idiot could plan a robbery, just like any rat could sneak through the cracks in wooden granary walls. But now that everything is cloudstone and clearsteel, with magical countermeasures over the few remaining holes, it takes a different breed of rat to survive.

"Slippery" Jimmy the Grey is one of the rare few ponies who can still slip through the cracks — even with the legendary Rainbow Corps on his tail. Now he's got a billion-bit heist planned in the gleaming skyscrapers of Cloudsdale. If only he hadn't made the mistake of stealing from a dragon …

Equestria is still picking up the pieces after the defeat of Tirek, and everypony is helping out with the paperwork, even Rainbow Dash. Things change when Princess Celestia arrives, bringing with her a letter with some very stunning accusations of the exploits of a resident in the town of Oasis. Now, the main six are tasked with finding out if the letter was truth or fiction. Did this Mister Baker really do what they claim? Only one way to find out.

However, Mister Baker is not who, or what they expected.

Ten years ago, the Griffon Empire opened a portal to a strange new world and tried to annex it. In the peace settlement that followed they lost control of the province containing the portal. Since then, the Griffonian Democratic Republic had been completely isolated, surrounded on all sides by a hostile empire. Now, for the first time, a visitor had been allowed.

The nation of Equestria has been exploring their little slice of the universe for some time now. From launching probes into deep space, to landing ponies on the moon. Sending things beyond the grasp of their planet has become almost routine. However, with every mission into space, there comes a time when the voyage must end. What happens when Equestria experiences the end of a voyage that they didn't begin?

Tartarus: the fabled prison said to hold all of the demons of Equus at bay.

Few truly know what lies behind the impenetrable doors Cerberus guards. Some say that it is a pit, infinite in it's depth and darkness, from which there is no return. Other claim it to be a hellish plain, filled with fire and pain and suffering, to punish the demons for their sins.

All of them are wrong.

Tartarus is small. An inescapable cell for a single prisoner. But the tales about it's purpose are not false.

For this captive human holds the key to unleashing upon Equestria forces which have not been seen for centuries, forces which predate Equestria by many an age.

And soon, he shall be free.

Twilight has developed a device that can detect strange signals coming from outer space; signals from aliens! She gathers her friends so that they can all listen in.

But they may not like what they hear...

I'd appreciate if everyone could keep the YouTube embeds in the comments to a minimum. The sheer number of them is putting a bit more strain on my connection than I'd like. I'm going to start deleting any comments with 2 or more embeds in them.

North of Canterlot, in the far marches of Equestria near the border with the Griffon tribes, there is a mountain that flies.

West of Canterlot, beyond the Galloping Mountains and a desert painted in the pastel hues of a faded rainbow, a tower sits at the edge of the world.

South of Canterlot, past the Everfree forest and the desolate badlands, a city of gardens waits to be born.
