After a particularly nasty run in with a monster during a mission from the map, Twilight discovers that she has apparently gained immortality due to her ascension as an alicorn. With this realization, Twilight and Spike go to visit the Royal Sisters to study immortality and get some advice.

Instead, Twilight finds herself flung into a whirlwind of confusion.

Now featuring significantly less errors! Thanks to everyone who pointed those out in the comments, and if you see any more feel free to point them out too.

Written for F*** This Prompt 13, "Immortality makes ponies very emotional."

Celestia discovers a lingering trace of Nightmare Moon's soul still lodged in Twilight's mind—a survivor of the lingering effects of the Element's magic.

Faced with the threat of gradually losing her friend to Nightmare Moon's evil influence, Celestia realizes the only way to save Twilight is to let the storm of dark magic take its course all at once.

And yet, as Nightmare Moon's corrupting magic tears away at Twilight's forgiveness and understanding, and Twilight begins dredging up unexpressed doubts once kept controlled, Celestia must face a lifetime of confrontation her student has kept covered.

It is going to be a long night for both alicorns.

This story was written for the Tenth Bimonthly Twilestia Contest. It placed somewhere.

Luna feels dread, knowing even before her banishment, both her night and herself have never been appraised by ponies. This changes however, when she realizes that her sister's student has feelings for her AND her night. This story is sad, due to the dread that Luna feels throughout the entirety of it. However, it does have a happy ending!

It's also a LunaLight/whatever the shipping is called for Twilight and Luna

Luna ruins a painting. No big deal, it was just the night after all.

Twilight gets a visit from a familiar stranger. Except it's not a stranger. It's Twilight, from the future. As future Twilight hangs out with past Twilight, past Twilight comes to a startling realisation... Her future self is kind of a jerk!

Quite obviously blatantly copied from based and expanded from this comic by 1trickpone.

Preread by Chicago Ted, thanks!

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.
List of editors, thanks for fixing grammar guys, you did a great job:

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.

Thanks to QueenCold for letting me use this picture of theirs as cover art!

Only a small number of bat ponies remained in Equestria after the disaster of Nightmare Moon. The majority fled, not trusting the nation after being betrayed by their own Princess. But with Luna's thousand year exile having come to a close, it is time for them to rejoin the fold, and no pony is better suited for negotiating that task than the Princess of Friendship herself.

However, when the captain of your escort is Indigo Zap, who suffers from a severe case of Lust At First Sight, and has an ego to put Rainbow Dash's to shame, things get a little more complicated than merely healing millennium-long tensions.

Thanks to bahatumay for pre-reading.

When Twilight is awake, Celestia is her teacher, and she a faithful student. But when Twilight shuts her eyes, another mare approaches, who teaches her a very different lesson.

An experimental fic, written to play around with alternative perspectives. Be warned, ye who enter here.

This story is a sequel to Growing Pains

After a magical mishap involving a filly, magical empowerment, and an aging spell, Twilight finds herself stuck with a rather large problem.

When Princess Celestia shows up to help her out however, it becomes apparent that Twilight isn't the only one affected by her new looks. Which in turn brings back feelings she had long thought forgotten.

Reading the prequel to this story is not required though it does help.

Enjoy.
