The pristine land of Equestria has grown a bit too peaceful and boring for the immortal sisters to handle so they decide to play a different kind of game. What started out as just a prank will quickly change into an obsession that nopony is safe from becoming a pawn in. The Shipping Games!

Co-Writer: True_Vision

After failing to stop Nightmare Moon in the ancient castle of the pony sisters, Twilight Sparkle is left with a scar that will permanently change the rest of her natural born life. As Twilight recovers from her ordeal, she finds that she is left with a difficult choice. Either live her life as a lie or sacrifice her innocence to protect the ones she loves. The path before her is set and she must now walk it alone. The sands of time continues ever onward, with everyone already trapped in its muddy depths. The sun will rise and the sun will fall. Waiting for its call, Death awaits for all.

I just put the two together

The Ponyspawn have invaded Equestria, and it is up to the newest addition to the Grey Wardens, Twilight Sparkle, to find the means to drive them back! With her friends and allies at her side, can Twilight defeat the evil tide before all of Equestria is devoured?

The Sequel, Pony Age: Catalyst, is available.

Applebloom has been having nightmares about Sunny Town for weeks. However, Sunny Town is believed to be a myth by all of Equestria. In order to solve this mystery, the Mane Six, Applebloom, and Spike head into the Everfree Forest to find the source of the problem.

A seemingly normal day for Twilight takes a very eventful change as she becomes accepted into the 'The Black Hoof', a group feared for the unconventional methods into public humiliations, taking revenge on behalf of others...
With pies.

Twilight, an 'assassin'?
Facehoofing ensues.

First ever fic and thank you all for the support! Revisions of it will be done at some point: looking back... it needs it.

The Elements of Harmony are known to many as the most powerful form of magic known to Equestria. Together, their combined might has cleansed deities as powerful as Nightmare Moon of the evil that plagued her, and has imprisoned forces as insidious as Discord, the embodiment of Chaos itself.

So when news of six mysterious strangers, evidently not of this world, arrives in a letter from the Princess, with rumors abound that they are searching for the Bearers of the Elements, Twilight Sparkle is rather concerned, and more than a little suspicious, of their intentions for the Elements of Harmony, fearing that they might be plotting to either destroy them, or somehow steal its power for some unknown, nefarious purpose...

Except that they're not plotting the theft, or destruction, of the Elements.

They're plotting a succession - a succession of power UNTO the Bearers of the Elements. Powers the likes of which ponykind has never witnessed - and power which may upset the balance of magic in Equestria forever...

Book One of Three of the Codex: Equestria, and the first part of an epic trilogy that will shake the very foundations of Equestria as we know it.

While conducting some late-night research for an assignment from the princess Twilight Sparkle is sidetracked by a book entitled 'Dear Princess Luna'. Upon analysis the young mare finds herself reading the story of her life...if Princess Luna took Princess Celestia's place as her tutor. As Twilight reads on and on she begins to realise how conflicted as to how lucky...or unlucky she had been to be taught by Celestia.

How do you cope when all your friends are dying of old age around you, but you seem not to be growing older at all? Twilight Sparkle tackles this problem for herself the only way she's ever known how: research, and then contacting Princess Celestia for advice. The explanation she gets is nothing like what she could have expected, and it will change Twilight's life forever.

Luna's isolation and difficult reentry into Equestrian life has left her without the confidence to communicate with the ponies around her. Especially the one pony she most wants to talk to. Celestia is angry, Twilight is upset and it's all her fault. Then she has an idea... She'll invite Twilight into her dreams. What could possibly go wrong?
