This story is a sequel to In the Eye of the Storm

A half-remembered dream leads Twilight Sparkle to test a new "window" spell by looking at an alternate Equestria. What she sees there will lead her and her friend Princess Luna into adventures they had never imagined possible. A season one fic.
As featured on Equestria Daily.

This is technically a sequel to In the Eye of the Storm as it's using the same versions of Twilight and Luna, but you can absolutely read this story without having read that first.

I began writing this story during season 1. I've updated some things to reflect canon changes in season 2, however at that point I decided that having to constantly go back and change things every time something new happened on the show just wasn't going to work, so the story ignores most of season 2, and everything from season 3 onward.

This story owes much of its quality to Jordanis, who is practically the co-author at this point.

Nightmare Moon had finally broken free of her prison. It was time to get her revenge on Celestia and bring about night eternal. Six mortal ponies rose up to stop her, using the power of the Elements of Harmony.

When the dust had cleared Nightmare Moon was gone, but so was Luna.

Be warned, there may be spoilers in the comments.

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?”

I should have refused to follow him for a night at the bar. I should have stayed at home. Why did I do that? What was I trying to prove?

Our main character has a nasty habit of falling into deep slumbers and waking up where he doesn't know where he is. In fact, the first place he wakes up...
... is in Hell.
---
Through some horrifying circumstances, the blue armor that was scattered in the ruins of the Royal Sisters' Castle reconstitutes the vessel of Nightmare Moon. Only this time, a human soul is its life source.
---
Rated Teen for some questionably older implications toward the beginning. In contrast, pyromaniacs will find said implications very underwhelming.

Edit: This story was written solely for entertainment purposes. Please do not dive into this expecting a well-tested chemistry report.

Edit: I think I found a cover that just might work for now.

What should one do when they find their current knowledge lacking? After the changeling attack, Twilight has to answer that question and for her the solution is simple enough. But her chosen path may yet turn out to be her downfall. Will the cost of knowledge be too high? Or will she be victorious in her journey into the paths of darker magic? One way or another Twilight will find it out as she learns under her new teacher. There is however one thing everypony close to Twilight should remember, that history likes to repeat itself...

A/N: Tags will probably be added as the story progresses. Updates may be irregular. Flames will be ignored, constructive criticism is welcomed. Now the image: background by me (and it shows), NMM recolor by DoctorXFizzle.

Applejack is chosen as The Nightmare's new host.

It really isn't that big of a deal. Until it is.

Several years had passed after Tirek's defeat and everypony is preparing for this year's Summer Sun Celebration. But Twilight is not feeling well. Several nightmares are haunting her, she has got bad headaches and a really mad mood. Although Spike and the others tell her to go and fetch help, she refuses. But when some dark incidents and curses happen, Twilight realices too late, they had walked into a trap and it has snapped behind them. For the foe is inside of her and preparing her last and final strike. To turn the celebration into a true nightmare.

Allen Keller has turned his life around thanks to a certain show his mother made him watch. Season Three has ended and everyone is awaiting the promised fourth. The problem is that one night he went to sleep and when he woke up the next morning he found himself in the body of a pony. A certain villain that almost no one likes in the first place. Life just got more interesting again.

What could have happened if Nightmare Moon had won over Twilight Sparkle and her friends? The tome Princess Celestia gives Twilight explains what she saw while using a spell. It shows a new threat to Equestria, as well, and Princess Celestia said this story has no happy ending.

Story Two of the Haven Trilogy, a partial sequel to Solar Flare concerning the second tome Twilight Sparkle received. I don't feel this is close to the best I could do, considering that when this was written, I was suffering from an immense case of Writer's Block.
