The sun has gone out over Equestria, sending Princess Twilight Sparkle and her friends off to Canterlot to deal with whatever new villain has caused the disaster.

...thankfully, it turns out to be a far smaller problem than anticipated.

This story is a sequel to Sharing the Night

Twilight Sparkle is the alicorn of the stars, and after a period of self-discovery, ancient-goddess-discovery and a minor case of malmanifestation madness, she has finally come to share the night, a city, her ex-villain status and a bed with Luna, the alicorn of the moon.

Things are looking pretty good for her.

The five demigoddesses she created out of spite? Not so much. Celestia and Celestia are a little lost too, and for some unknown, completely mysterious reason, dragons are flooding into Equestria—and they're not acclimating. Someone probably should do something about that.

It never gets dull in Ponyville, does it?

TV Tropes

This story is a sequel to Past Sins

When pursuing Starlight, Twilight and Spike experienced variances of Equestria, and saw how the river of time could have been different. Now, Starlight has moved in with Twilight, Nyx, and Spike and has begun her studies in friendship. To thank those who have helped her embrace friendship once more, Starlight has created an enchantment that allows the castle’s map table to let anyone glimpse other variances of reality.

The power to ask “what if,” can be a source of great amusement… but for some, the hypotheticals are haunting reminders of what could have been.

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?

A young man finds himself in the bedroom of an attractive young woman. Unfortunately, something is telling this man he's going to have a bad time. Something in the woman's eyes...

Love Tap has a reputation for being excellent at taking care of children. Twilight needs somepony to help look after the sirens. These two things really shouldn't have any connection, but desperate times call for desperate measures.

Spiritual sequel to The SweetieMash Chronicles. Though reading SweetieMash is not compulsory for enjoyment of this story, it helps fill some blanks.

Princess Changeling Rainbow Magic Pants, the beloved being from beyond Equestria's skies who also resides in a land flooded with magic much as if Starswirl the Bearded's basement was flooded, senses that Twilight Sparkle needs her help.

Now if only ponies would stop screaming or throwing up every time they laid eyes upon her.

Sonata has a tooth ache. Adagio and Aria don't want to deal with it. Sunset Shimmer gets involved. Applejack is there. It's gonna be one of those days.

Inspired by a conversation with Tired Old Man, naturally.

Rated "Teen" and tagged with "Sex" because of Adagio freakin' Dazzle

Sunset Shimmer, twice savior of Canterlot High who earned her wings by using the combined magic of the Earth elements of harmony to save the world from Twilight Sparkle (you know... the one with the glasses). She's offered to help Twilight's (you know.. the alicorn Princess of Friendship) new student learn about friendship while the whole crew embarks on a trip to the Crystal Empire. This should be a fairly relaxing and stress free trip. Right? RIGHT?!

It should go without saying, but MAJOR spoilers to the season 6 premier.

Twilight Sparkle isn't feeling too well, and it is up to Princess Celestia to nurse her back to health. It would be a simple task, if not for the fact that her student was thirteen years old with an uncontrollable amount of magic.

To make matters worse, six years ago Celestia was forced to shrink Twilight to 1/100th of her size so that her untamed magic wouldn't be a threat to Equestria. She would have to remain tiny until she would learn how to control her enormous power.

But surely a two millenia old alicorn with enough magic to destroy a small mountain can handle her littlest, fragile and most magical subject... right... right?

This sidestory takes place between chapters 4 and 5 in Celestia's Tiny Student.

Special thanks for pre-reading to ambion, I took some inspiration from his story called melt, worth checking it out for additional dose of cuteness.
