This story is a sequel to The Flight of the Alicorn

Rarity was certain her troubles with magical gemstones had ended, but an unexpected royal visit soon convinces her otherwise. In order to save an ailing Princess, stop an ancient menace, and avert a disaster that threatens the survival of a lost tribe of ponies, Rarity, Blueblood, and a brave group of friends will travel to strange and foreign lands, and into the fathomless depths beneath tormented seas. In her quest to uncover the secrets of the Abyssal Forge, Rarity will have to use all her charm, wit, and skill—and rely on allies old and new—as the unlikeliest of ponies once again attempts to save the world in style.

Set in the Optimalverse, a middle-aged woman enamored of 'Equestria Online' confronts what permanent emigration to Equestria - uploading to a virtual existence - really means... but can she even hope to truly understand such a thing - and more importantly, can she trust the artificial intelligence known as 'Celestia'?

♥ As Horrified Eliezer Yudkowsky!

An idea I had after I got my first blind bag pony. Don't take it too seriously, as it's all ment to be a big 'ol pile of crack and random insanity just so I could get the idea out of my head! Enjoy! Art by Names76.

Twilight gets a mysterious letter from her parents, explaining that they have urgent news to tell her. However the trip, and the arrival, and even the news, are far more warped than she could have ever imagined.

“My daughter Celestia, look at me. I love you, and I wish the best for you in the eons of labor you have yet to endure. So heed my words. When we planted light upon the fields of Creation, Celestia, it was a divine thing. But there will come a time when our brilliance won't be enough. It will take a great, unknowable darkness to test the luminescence that we have bequeathed life. That is an abyss that we can never, ever follow our children down, no matter how much we love them.”

A Silver Medalist of the Ponychan /Fic/ Write-Off: "Cutting Ties"

A horrible Cataclysm has turned all of Equestria into a Wasteland of barren ash and twilight desolation. The Sun and the Moon have been destroyed. Everypony has died--including Princesses Luna and Celestia. But one pony miraculously survives; she is a lone wanderer, the last of her kind, surrounded by menacing creatures that hate her. She navigates the Wastes in an airship and scavenges off the blighted landscape to keep herself alive.

Then one day she meets an old companion who grants her a gift, the chance to go back in time to the warm and sunny days of Ponyville, where her dead friends live in happiness. How far will the last pony venture into this joyous age of Equestria, even if she fully knows that there is no way to change the horrible fate of everypony she loves?

It's been a few weeks since Luna's returned from the moon, and all is not well. She's become more introverted than ever, rarely leaving her room and obsessing over work. Celestia hopes that studying Twilight Sparkle's Friendship Reports will at least help her get out of her shell, though an unusually talkative servant may just help in that regard...and is anypony else getting strange feelings from that statue out in the gardens?

As of May 4th, now featured on Equestria Daily. *Squee*

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?
