Luna's return was met with significant fanfare, though with all the fuss dying down, and with the formal re-establishment of the night court months away, Luna seems to have had little to do other than lounging around.

or so Celestia thinks.

When she finds Luna entering the Ministry of Records unannounced she wonders, Just what is her little sister up to?

Edit: WOOO! Featured on June 2, 2015 (at least in my country's timezone i think) Thanks to everyone!

Twilight had planned to visit Sunset Shimmer and her friends over in the other world for a nice, quiet weekend, away from all the worries and problems associated with being a Princess of Equestria. Unfortunately, things rarely go as planned.

After an accident cuts her off from Equestria, Twilight finds herself stuck in the human world until the gateway between the two worlds can be fixed. Which wouldn't normally be a problem...

...If she wasn't still a pony.

Now with TvTropes page!

Sunset Shimmer has finally rebuilt her life at Canterlot High. She has friends, she's in a band, people like her, everything's going great...

And then out of nowhere, she turns back into a small talking unicorn.

Now, with the help of her friends, she has to figure out why she's suddenly a pony in a human world, and whether or not she can become human again...or will have to leave her new life and go back to Equestria.

Now with a TVTropes page!

Sunset Shimmer still doesn't fully understand how the magic that transforms her and her friends works. She's close to figuring it out though, or so she thought. When a magical "fluke" occurs during a band practice, will the girls, along with the Twilight of their world, be able to figure out what happened, and will they be able to fix it?

Takes place about a week or two after the Friendship Games

This is my first story, so it might be good, it might crash and burn. I am ready for criticism, and prepared for the worst. If you see any spelling or grammatical errors please let me know in the comments.
This idea came from reading Oops! I'm Equine Again by MythrilMoth!

Princess Celestia has no problem with leaving the three Sirens in the realm across the mirror, in effect dumping her own world’s problems on another world. Princess Twilight Sparkle makes regular visits. Sunset Shimmer, while redeemed and intent on staying there, is still a foreigner to the human realm. Sunset knows this status quo can't last, especially after not one but two schools know about magic following the Friendship Games.

Sunset soon decides that, if Equestria has no problem with its own citizens visiting other dimensions, it better be prepared to allow the reverse. Thus begins Sunset's Extradimensional Tourist Agency.

What freaks her out is just how many people adore the idea of temporarily becoming magical coloured ponies.

Other Characters tag includes the Shadow Five. Sex Rating will be for innuendo and references.

Changeling Twilight Sparkle and her number-one assistant, Sunset Shimmer, try to study magic without learning any wholesome lessons of friendship. They fail.

Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”

My first story for everyone. Need to be careful around cussing, 'cause that's why I normally rate everything T.

You know I thought why not turn Sunset Shimmer into a unicorn, while she's still at CHS? Why not adding human Twilight later on? This takes place after Rainbow Rocks and yes, Sunset will have her magic abilities. What fun in having a unicorn without magic?

08/11/2015 Okay, featured because 5 people are watching my new chapter. No wait, 4, I accidentally counted myself. I think the system is a little broken.

What the buck?!?!?!??
Sunset wanted to scream as she stared at the mirror. She was an alicorn, a freaking alicorn! Wait, what? Celestia is her mother? And did the sun deity really just said her little sister Twilight waited at the breakfast table?
Having a total overload, her brain decided to make an emergency restard. Sunset fainted. {Will include EG}

I've had this idea for a while with Sunset and Twilight being sisters. I'm sorry, but I couldn't make the beginning any better. Future chapters will be longer and hopefully better written. Tell me what you think about the General idea.

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?
