This is an idea that wouldn't leave my head, inspired by Fairy Slayer's "Mommy Nearest," Aldea Donder's "Alicorn," SoundofRainfall's "Play" and RainbowDoubleDash's "Lunaverse"

Alternate Universe: Instead of Twilight Sparkle, Princess Celestia made Rainbow Dash her personal student instead! Follow her through the events of the 1,000th Summer Sun Celebration. A reimagining of "Friendship is Magic"

You think you know me so well, don’t you? I’m a spirit of chaos, and nothing else. You don’t even know the half of it! Sit back and indulge me for a little; I’ll make you understand what it truly means to be chaos itself.

(Featured on Equestria Daily: July 16, 2012.)

Princess Celestia had been going to spend the evening in a royal mope, but Pinkie Pie has other plans for the night, plans which involve piercing the walls of time and space with her most ambitious birthday greeting yet.

Now with a Spanish translation by Spaniard Kiwi!

Lyra knows the truth. Lyra knows that a shadowy conspiracy dating back to the very dawn of Equestria is responsible for manipulating every major event for the past two thousand years. And Lyra does not care how many museums she has to destroy or how many transdimensional rifts she has to open in her quest to inform the public.

This story is a sequel to The Ambassador's Son

Lord Sapphire lays dead and Tacksworn is in ruins, but Chiphoof Irontail has come home to his adoptive father, Sharptooth the dragon. Amidst the destruction and chaos, the community and the circles of friendship within must rise again to face an uncertain future. The young scion of the Diamond Expanse Clan must now face his greatest threat as the forces of war build to a crescendo. With his friends by his side, together they will uncover forbidden mysteries and face off against ancient powers that have lain dormant for centuries.

980 years ago...
Celestia has been trapped in the sun for twenty years now. They have been hard times for the ponies of Equestria as they have sought to try and rebuild their society and recover from all that she did in her madness. But fear not! For though her coat and mane are now pink, and though she is shorter, and though she remembers nothing of her previous life, all that Celestia was has been reborn, and returned to Equestria!

A distant prequel to the Lunaverse.

It had to happen eventually.
...actually, no. No, it really didn't.
Set immediately after the events of Boast Busters, Trixie finds herself in a quandary when she realises that she has left her purse behind in Ponyville. She faces a humiliating walk back into town to pick up her money.
Before she can turn back, however, she meets a magical, sentient pine cone... sigh. Okay. Here's a proposition.
If you can make it to the end of this story without going "what" even once, you win a free internet.

This story is a sequel to Petriculture

It's been several months since Pinkie Pie made a stunning admission about her past that permanently changed her relationship with her friends, particularly Twilight Sparkle, but life seems to have settled back to normal (well, normal by Pinkie Pie's standards, at least). However, when an old nemesis returns and ensnares Twilight in her influence, it's up to Pinkie to make things right.

This is the second story in The Petriculture Cycle. There is a TV Tropes Page for the entire Cycle here.

Okay, I don't know if anyone can hear this, or read this, or whatever, but I'm trying my best to use Pinkie Pie's legendary fourth-wall-breaking powers to try and get a message out.

If you can hear this, I need help. I'm in Equestria, and man, this is strange. But I'm also stuck in Pinkie Pie's body, for some reason.

Yes, it's just as weird as it sounds. And now, I need your help... because all the ponies in this town think I'm crazy!

Queen Gaea, mother to Celestia and Luna, has sensed many disturbances over the past few years. She worries about the kingdom she left to her daughters so long ago, and sets out to reunite with them. Her mate, Poseidon, worries for Gaea's safety, and sets out after her. However, things don't go as planned, and dark forces are inadvertently set in motion that threaten the peace of Equestria and the lands beyond.
