A meeting of some fanon incarnations of Celestia.

Twilight and friends learn that prolonged exposure to the power of Pinkie Pie can cause some rather interesting side effects. An unbearably silly idea that wouldn't go away until I wrote it down.

This is the story of the end. This is the story of the death of Equestria. It is the story of the reign of her royal majesty, Princess Twilight Sparkle of the Fading Sun.

The alicorn sisters are dead and Equestria has turned to Twilight Sparkle to guide it. However, just maintaining a dim sun a fraction as bright as her mentor's keeps the new princess near her limits.

Years have passed and Twilight Sparkle is sure of only one thing. Equestria is dying.

NOTE: Written before "It's about Time" in season 2. Everything after "Read it and Weep" was ignored throughout this story.

After a brief spat with Spike over a seemingly trivial matter Twilight decides that in order to learn more about dragons she should try to become one. With a simple spell she transforms her little pony self into a larger dragon and quickly realizes that she has no way to change back available to her....

Twilight, Pinkie, AJ, and Rarity no longer remember anything about the Secret of the Pegasi, but there's one thing Rainbow and Fluttershy overlooked: how did the letter that Twilight wrote about the Secret get to Celestia?
Exactly.
When Twilight comes stumbling back home with a hangover and no memory of the previous day, Spike discovers that he's suddenly alone in knowing about the mystery of removable wings. An off-handed comment by the worn-out unicorn prompts Spike into an investigation that will shed more light on the truth behind the conspiracy and raise even more questions.

What if? Two simple words that evoke an endless compendium of fantastical possibility. It is theorized that whenever anypony anywhere is presented with any choice, the universe splits, creating parallel worlds, one for each decision. Take a peek into a variety of these parallel universes, see what could have been, would have been, and what kind of Equestria would be created by this altered history.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

At first glance, Princess Luna's charioteers might appear to be little more than Royal Guards dressed in festive apparel for Nightmare Night. However, there is far more to the story than that - the Night Guards once played a pivotal role in the history of Equestria, and have sacrificed more for their beloved princess than most ponies are even aware of.

A short trip to Canterlot with Rainbow Dash and Applejack is the perfect opportunity for Twilight to test out her new long-distance Teleportation spell. But a nasty cold dashes the hopes of a quick trip, and makes the spell disappear in smoke: instead of arriving in Canterlot, the three find themselves in the nearby Everfree Forest, and discover that their location is not the only thing that went wrong.

While Rainbow has exchanged her wings and tail for a straw blond tail, Applejack has acquired a rainbow tail as well as a pair of strong, blue wings.

While Twilight attempts to find a spell to return the body parts to their rightful owners, the others must attempt to deal with this situation... and with their changing feelings.
