This story is a sequel to Dreams and Disasters

Rainbow Dash has a new problem.

It isn’t that her relationship with Twilight Sparkle has diminished in the year that they have been together, even despite Twilight’s new position as an Equestrian Princess. If anything, the past year has brought them closer together than before. As far as Rainbow Dash is concerned, her life is pretty much perfect. That is, until she notices that her colors are fading.

In a panic to discover what is happening to her, she stumbles headfirst into an ancient secret dating back to long before the formation of Equestria, with her family in the middle. With Twilight and her friends, both old and new, at her side, she will once again venture out into the wide world of Equus, not for love, but for answers. About her family, her heritage, and the theft of the oldest artifact known to pony kind: The Celestial Prism.

Takes place canonically shortly after the Season 3 finale and well before the Season 4 Premier

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

As a child, Daphne knew of a world where magic lived, where an immortal princess reigned over a beautiful kingdom, and longed to journey there beside Leit Motif, the filly she'd grown to love in the woods behind her home. But one day, when she needed her most, Leit Motif was gone, and she never came back to show her the way. As she grew, she put aside her childish dreams, and taught herself to believe the lie.
When forces beyond her knowing take her sister Amelia, though, she discovers that her childhood fancies were entirely too real, and is thrust into a journey that will take her back to that land she longed for, back to the childhood friend she'd abandoned, and to worlds she'd only dreamed of.

This story is a sequel to Dusk's Dangerous Game

Twilight Sparkle, known to all but the three Goddesses as Lady Everstar, the Evening Sage, has ruled over her kingdom for nearly five centuries with all the wisdom and grace of which she is capable. Her lands are wild and exciting, the prospects good for those with brilliant minds and daring hearts. But now something has changed in the Evening Kingdom, something has changed the balance of power so profoundly that even Twilight herself cannot tell how events may unfold.

Across the ocean, an ancient evil is stirring, its dark hunger can finally be realized. Its servants are many, brutal, and cunning. They are found among the lowest of lows, and the highest of highs. With the balance of power so disrupted, it is at last time for their shadowy plans to come to fruition, to cast off the darkness and strike against the night.

It will take the power of goddesses, magic both familiar and ancient, and the most unlikely of heroes to save not only the Evening Kingdom, not only Equestria, but the entirety of Creation as we know it.

Sequel to Lines and Webs and Dusk's Dangerous Game. Knowledge of the previous stories is not needed, but reading them is, of course, encouraged.

Followed by Courts of The Magi.

Twilight is invited to Canterlot to compete with some of the greatest magicians in the world for the Moonstone Cup, a prestigious award for the most powerful and skillful magicians, unicorn and otherwise. Can she win? What sort of competition will she face?

Awesome cover image was taken from NoOneBahtim

Inspired by the story image, RainbowDoubleDash's Lunaverse and Trinary's "Rainbooms and Royalty", I give you my take on the alternate universe concept. Namely, a universe where Spike is the pony and Twilight is his dragon assistant.

The thousandth Summer Sun Celebration is approaching. With it will come the return of Nightmare Moon. Celestia has no student to call upon to save Equestria, and is doing all she can to make the last day of peace meaningful for her people.

Meanwhile, Spike "Purple Prose" Flail is a reporter for the Canterlot Sun. He finds himself being shipped down to the boonies with his longtime friend and assistant, Twilight, to cover the biggest festival Equestria has seen in a millennium!

But even with a visit from the princess, there's no way someplace as boring as Ponyville could ever be newsworthy. Right?

Story would also include character tags for Thunderlane and Cheerilee if not for the character tag limit.

Now has a TVTropes page!

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.
