This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

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...

Traveling between parallel universes is impossible, especially during the process of regeneration, but the Tenth Doctor doesn't have time to question the facts. He's just been thrust through a tear in the fabric of reality, gotten a new body, and landed on a planet called Equestria. Specifically, he's landed in the worst possible place in all Equestria – somewhere that's ready to unleash a “big ol' storm of chaos”.

That's just the beginning of the Doctor's strange new lease on life: there's a whole host of mysteries to explore. Who is Derpy Hooves, the gray pegasus who understands more about him than even she knows how to explain? How does Princess Celestia already know him? And what's the truth behind the Order?

Above all, the Doctor needs to discover if this new universe can heal the wounds he suffered in the last. Only one thing is certain: there's an awful lot of running left to do.

(Warning: For those of you who haven't watched up to the Doctor Who episode 'The End of Time'... spoilers. Also, this story begins between Seasons 2 and 3 of FiM, and things start to... diverge from there.)

Story number one of the Twilight is Magic series. See the author notes in the first chapter for a link to the read order.

Twilight is the bearer of the Element of Magic, or is she? is it possible that the logic is in reverse? Twilight must learn that every action has consequences. Some are more damning than others even in the best of intentions. But with the power to save someone you love, can you honestly say you would do any different?

This story takes place approx six years after the first episode, Friendship is Magic part one. (Five years after EQG)

Twilight and Spike are rewarded some earned vacation time. Their chosen Destination? The land of Saddle Arabia, where Twilight ends up getting more then she bargained for when she's given a beautifully crafted bottle made just for her. Spike and Twilight find themselves in a situation they never thought was ever going to happen. And with such limited time, Twilight has to make the hardest decision of her entire life.

This is the fanfic version of the Origin Story from the Ask Genie Twilight Tumblr blog.

As Twilight deals with life as the head of a nation and the responsibility that comes with it , she must also deal with her secret relationship with a certain moon goddess. As they face various issues from the get go. Including intense media and public scrutiny, a commitment to her friends and family, the complexities of the Equestrian political system and Luna's struggle to find peace with herself and her faults.

With a political crisis brewing on the horizon, Twilight must come to terms with her position quickly while also coming facing a daunting task in the form of reconciling Luna and Celestia's damaged sisterly relationship. In the end she'll learn that being royalty isn't all what it is cut out to be.

I highly recommend reading the first story. It's not completely necessary but it will be easier to follow the plot.

Sequel to Learning curve

My second attempt at romance with Twilight and Luna. Starts off as fluff in the begining but develops a political side story as the chapters go by. The story mainly focuses on Twilight and Luna and the issues they deal with after Season 3. Written before season 4 so it may not conform fully to canon. May fix this in a later rewrite. Criticism is once again welcomed.

Hearth's Warming Eve is supposed to be a happy event—Cadance knows this, but all she ever feels is lonely. Now, with Shining Armor gone and a freak snowstorm battering her kingdom, it's up to Cadance to salvage the holiday and teach her crystal ponies to care for one another.

A story about finding your family, on the coldest night of the year.
