"Sunset, you weren't the first unearthly threat to come to this world, and you won't be the last. If we seem calm in the face of strange events, it's not because we're oblivious or indifferent to them. It's because they're not strange to us. The Fall Formal may have been the most important night of your life, but to us... it was Thursday."

(Slice-of-life adventures of Canterlot High's unlikely band of monster hunters.)

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.

Principal Celestia has accidentally fallen through the mirror into Equestria, and it may be a bit before she can go home. Until then, she has to learn to cope with a strange world, in a strange body.

At the same time, Twilight has to figure out how she can help her new guest while keeping Equestria from freaking out over the presence of a second Celestia, and Sunset Shimmer has to figure out how she is going to make amends with those she had left behind in Equestria, while keeping an eye on her Principal.

Disclaimer: Since I wrote this description ages ago before I even knew the plot, the story is mostly pure comedy in the beginning, with eventual Sunlight and Chryslestia shipping!

It is a strange time for those at Canterlot High. Magic is running rampant, creatures from beyond the cracks have invaded and worst of all, a strange, new being has been causing mischief. But aid comes in the form of a new teacher, one who can help Sunset learn about magic. Learn what it means to be a leader. For she is not a Man of Steel, nor a Dark Knight.

She's a wonder.

This story is a sequel to About Last Night

One month ago, Twilight Sparkle and Applejack got drunk and then got married.

Now Twilight's a princess, and the pair have to work on integrating that new aspect of it into their relationship. Add to that Spike's feelings on the matter and the fact that he's getting the attention of fillies his age, and Fluttershy and Rainbow Dash's relationship, maybe they're better off grabbing a few more drinks...

Sunset Shimmer has made many mistakes. She's been rude to others. She's been completely oblivious to the power that friendship has. And she's turned into a massive, flaming demon of rage and attempted to enslave a small group of teenage students.

Sunset's had plenty of time to learn from her mistakes in the human world, but home is where the heart is, and Sunset Shimmer is ready to see it again.

Now with a Sequel!

Rated T for mild profanity.

In her successful attempt to stop Twilight Sparkle, Sunset Shimmer ends up in the universe of The Batman. Now, with the help of her mentor Zatanna Zatara and two best friends—Barbara Gordon and Pamela Isley—she has to figure out her place in a brand new world.

My personal thanks go to Pen Stroke and Burraku_Pansa for helping me bounce this idea around and suffering through my naming process.

This story is a sequel to Direction

The Element of Magic has been stolen. Twilight has to venture through a magic mirror in order to get it back. On the other side, she finds a world filled with creatures she thought were legend, and yet they all wear familiar faces. Now, with the help of a local principal and a few helpful teens, she needs to track down Celestia's former student and get her Element back before it's too late.

The Nuptialverse's take on Equestria Girls. Happens simultaneously with Direction

This story is a sequel to Families

Third in the Nuptialverse...

Twilight Sparkle has done much for Equestria. If it weren't for her, Equestria would be destroyed three times over by now.

So what happens when she has to leave? What happens when she and Spike are forced to depart from Equestria in order to fulfill their duties? And what happens when there's still important things at home to do?

Applejack, Rarity, Pinkie Pie, Fluttershy, and Rainbow Dash now have to get along without the one who leads them. All of Equestria is counting on them. Can they do it?

AU only post-season 2, since the basic idea for this fic was created long before it aired. Events similar to season 3 have happened, all of which will be revealed. Strongly recommended you read Post Nuptials and Families first.

Spike's got three whole days to himself while Twilight is away at the Crystal Empire. Three whole days to be independent and free to do whatever he wants.

Or he would have, if a female dragon hadn't mistaken him for an abandoned hatchling. Now he's been snatched up and taken to her home to be "properly cared for."

Stuck in a cave with an overly-protective dragon intent on mothering him...maybe he should have just gone with Twilight.
