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?”

This is the story of a brony, who inserted into Equestria.
But instead of a pony, he became the enemy of Celestia.

Would he decide to do what’s right, to love and tolerate
Or would his evil changeling nature make it hard to integrate

Then there is the question of the duty that is his natural birthright
Tasked by the changeling Queen, he was to murder Princess Twilight

So, here’s my attempt at a SI with a bit of a twist that others have done before. Go to Equestria, end up on the wrong side of the tracks, and have to deal with it. Enjoy!

This story is a sequel to Aegis of the Hive

Natural selection. It is the byword of every changeling queen who has ever lived. The chief resource that has always curbed the hives' growth used to be love. Now though, with Queen Twilight Sparkle's bloodline capable of producing love on their own, the old guard of changeling morality has seen fit to acquire this ability for the next generation before removing all of their future royal daughters' competitors.

Some queens are far closer to this goal than others.

Editor in Chief: A Bitter Pill, and Boldish42

For most of Applejack's life, she didn't know what she was. True, she understood who she was well enough.
But ponies don't change shapes, nor do they get strength from love.
Applejack never thought too hard on it... until the events of a certain wedding brought about some harsh realizations.
Now, with Equestria still reeling from the surprise attack, will Applejack manage to come to terms with what she is? Will she even be able to keep her secret safe?
For if the royal guards don't get her first, the conspirators in the shadows just might...

This story is a sequel to The Irony of Applejack

Warning: this story is a sequel. Therefore, it is highly recommended that you read the prequel first before continuing!

Over half a year has passed since the changeling attack on Ponyville, and Applejack would like to think things have finally settled down. Much has changed for the young changeling, and all of Equestria in kind. The new district in Ponyville proves that, along with the town's many new residents.
But there is much the young queen does not yet know about being a changeling. Some things, she will learn, can be chosen, while others will be chosen for her. With new allies and enemies emerging all around her, Applejack must discover what it truly means to rule before the choice is taken from her forever, and the history of the changelings repeats itself, once again...

There is only one real rule regarding changeling royalty: there must always be a queen. Twilight Sparkle is about to learn this through personal experience.

Originally written for an X Becomes a Changeling prompt almost three years ago.
Set after season three.

Twilight Sparkle has spent months researching chaos magic, developing a new spell to unlock magic nopony has ever experienced before. But when something goes wrong with casting, Twilight finds herself turned into a Draconequus and unable to control her new chaos magic. If she ever wants to be a pony again, there is only one who can help her learn to control her new magic.

Of course, learning from Discord was never going to be simple. And after a while, being a draconequus doesn't seem so bad anyway....
