Professor Cooke is a pony of principles; anypony who has known him well can testify to that. As an established history professor at Canterlot University, he knows the dangers of opening borders to a hostile nation; his anti-changeling stance may seem harsh, but the safety of Equestria comes first. It's not about the species; it's the cultural dangers of a society of infiltrators, liars, and saboteurs on Equestria's border.

He's going to stand by those principles for the good of Equestria. Nothing can change that, not even one of his closest friends turning out to be a changeling... right?

(Can be read standalone, but serves as a sidefic to The Queen and I Book 2: People and Problems. Click here to see the larger fic 'verse.)

Everypony has secrets. Some secrets are embarrassing. Some secrets are just things you don't want to share publicly with others. Other secrets can rock your relationship to the core if revealed...

Written for the X Becomes a Changeling May Prompt.

This story is a sequel to If You Came to Conquer

Princess Nightmare Moon had tried to keep it secret. She had suppressed her power, feigned ignorance, played the outdated fool at every opportunity. She should have known that something like this would happen. A threat that would reveal her, whether she played dumb or not.

If she had to reveal herself, then at least she could protect Equestria in the process. She nocked the arrow. The bow felt so flimsy, but she could not risk him absorbing a spell. She laced magic across the arrow and the string and the air, enough to make it fly faster and aim smoother. She sighted him easily; Tirek was a large target. Now he only had to turn around. An arrow to the spine would kill him simply and instantly, no matter how much magic he had absorbed.

Once he was dead, the hard part would come: explaining herself to Celestia.

Octavia Melody and Vinyl Scratch are a lovely Manehatten couple and have been together for nearly a year and a half. They are happy and in love, the only problem is Octavia is a changeling. Octavia has been on the run for a long time and just when things are going there best it looks like her past has finally caught up with her. Just yesterday her only problem was her noisy neighbors Lyra and Bon Bon. Kind of based off of the song "The Sameling" with amazing cover art by Gift-Wrap on DeviantArt.com I give you Duel Melody.

Rainbow Dash, best pony, fastest flier in Equestria, all around awesome mare, was called upon to help with the wedding of her friend's big brother. And hey, she never leaves her friends hanging! Of course, when it turned out some kind of bug thing had replaced the bride, Rainbow was more then ready to fight. Heck, even after it seemed all hope was lost, the pegasus refused to give up.

So when she saw Shining Armor charge up a final spell, she smirked.

But when that spell reached her and flung her against the wall, her smirk devolved into shock...

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

Welcome to Trotondo, where the lakes freeze overnight and the snow never stops falling.
Welcome to the outermost Equestrian colony, where the foreign threat is so marginally low that only two royal pegasi guards were needed to keep it safe.
Welcome to the town protected by Dawn Guard and Dust Mote, two peacekeepers so hopelessly in love that they don't even know it.
... Thankfully, the other four hundred and thirty eight denizens of Trotondo are more than willing to help resolve this predicament.

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...

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

This story is a sequel to Stardust

Twilight has finally returned home from the harrowing challenge that Discord set upon her, and the residents of Ponyville and the Elements especially look forward to having their dear friend returned to them.

Twilight, however, has changed. Still suffering from her injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her. Will her frustration at her current state and her friends inability to understand her experiences cost her what she valued most before Discord's bet?

(Sequel to Stardust, familiarity with this is recommended!)
(Proofread by Arzoo!)
(Coverart commission drawn by the amazing KairaAnix!)
(Crossover with XCOM: Enemy Within, though the crossover and human elements are minimal)
(Featured 4/28/2014, thanks folks!)
