Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

TV Tropes

After discovering that Cadence is not who she appears to be, Twilight is sent to another world entirely by the disguised Changeling Queen to avoid her plan being disrupted.
When Twilight lands, she discovers that not only have Spike, Owlowiscious and Peewee followed her, but that they've arrived in a world where the main sentient species is human.
There's still a place where they teach magic, though.
Crossover with Harry Potter. Twilight will be effectively taking the role of Hermione.

I've marked this story as cancelled to reflect the unlikelihood of it continuing. If I do come back to it I'll revert that.

Today is Princess Twilight Sparkle’s 500th birthday, and her most faithful student, an earth pony with a familiar name, can’t wait to celebrate!

During the entrance exam to Celestia's School for Gifted Unicorns, Twilight completely loses control of her magic. Celestia tries in vain to calm her down, but having no other choice she's forced to use a shrinking spell on the filly in order to tone down her dangerous surge of power.

After the exam, Celestia takes the tiny Twilight as her personal student to teach the young unicorn control over her powerful magic, making sure that she will pose no threat to other beings.

Will tiny Twilight be able to step out into a world designed for someone far larger than her? And will her size impede her in the trials of life as princess personal student ?

What if Twilight was orphaned before her acceptance into Celestia's school for gifted unicorns?
what if she and the princess of the sun became inseparable? What if Twilight starts calling Celestia mommy after their lessons?
What if Celestia loves it?

This story is a sequel to A Stitch in Time

Having discovered the message left for her by Star Swirl the Bearded in the distant past, Twilight once again finds herself caught up in the middle of a struggle against forces far greater than herself. In order to even stand a chance she'll need to travel further and wider than she ever has, and forge some unlikely alliances with old enemies. All to bring down the powers that have manipulated and shaped her entire life, and retake control of her own future.

It's been eighty-nine days since the Day of Darkness, and Twilight Sparkle is still on her own. Eighty-nine days since she talked to anyone other than herself. Regardless of how lonely she feels, she prefers the company of herself to the vicious "lurkers", as she calls them, roaming around outside of her library. Whatever friendly, loving creatures they were before the Day of Darkness, something changed them. Something created these insane creatures, and nothing, not even Twilight, can stop them. All Twilight can do is live — live to fight another day.

Twilight had always been a diligent researcher. She would routinely pour over every book she had at her disposal in preparation for every royal assignment. Except, sometimes books can only teach one so much. With this heretical idea in mind, Fluttershy and Rainbow Dash decide to take it upon themselves to make sure Twilight keeps her wings clean, and doesn't embarrass herself in the sky.

What would you do if you woke up with god-like powers? What if the Goddess you love is without her own magic? What if Pinkie Pie's alicorn fetish was never important, until now? What if you're Twilight Sparkle and nothing makes sense anymore? The Answer: Equestria is sooooo boned.

Belated thanks for excellent editing of this beast goes out to Knight of Cerebus.

General encouragement/idea bouncing help from Misago.

Twilight has something she needs to tell Princess Celestia--something that means a chance at getting everything she's ever wanted, or of losing everything she's ever had.

Something so terrifying that the only way she could say it was in a letter...and so wonderful that she had the courage to send it.
