This story is a sequel to Triptych

The war touched everypony, even those far from the fighting. Compass Rose was affected more than most when gryphons appeared far behind the front lines, and the aftermath left her unwillingly in the company of an enemy soldier.

Set in the same universe as Off The Edge Of The Map, Apotheosis, and Triptych.

Editing by Kaorin.

Synopsis

Greed strengthens a dragon. But what of the opposite? Spike feels a little bit of himself broken away with each passing day as Rarity flaunts her newfound love with another stallion. But that's the least of his troubles. A formal gala for which he is the guest of honour quickly approaches. With the relationship between the Council of Friendship and the nobles of Equestria at stake, he is certain this gala could only end in a big political disaster. Enter Princess Luna, cunningly disguised as the sweet elegant mare by his side, intent on turning him from a laughingstock into the star of the show. But jealousy and misfortune swiftly strike, leaving Luna permanently stuck in her disguise. Together they must maintain their cover until they somehow figure out how to fix everything. As the days pass, as the 'one more day's turn into a week, they slowly come to a startling realization - Perhaps there is nothing to fix?

'We’re taken on an adventure, and if I dare say, we aren’t just told the damn story. We’re allowed to experience it. Spike has a moment, and I feel warmth. Luna tosses off the royal baggage, and I feel the feels. This is a great and glorious orchestration in romance...' - Wing

'Bravo! Bravo! ...I'm not into Romance stories because I don't really like them at all but this story here...This is my favorite!' - PlatinumPony

'I don't think I can accurately express how much I truly enjoy this story, right now. When the characters are happy, I'm happy. When they're not, I'm not. It's all so perfectly done that it's like I'm living the story instead of merely just reading it off a page. This already wins first place for most adorable story I have ever read...' - Drgnwolf

'Oh my Gods the feels! I smiled, laughed, got very angry and very sad all in one chapter! Please oh please complete this awesome tale soon! The suspense is killing me!' - Wiriamuzu

'I always wait until a story is finished before thinking about adding it to my favorites. Always. I have never added a story to my favorites before it's finished. This story is the one exception.' - Jomp

'Yeah. You just made a grown-ass man make a 'squee' sound.' - HoneyBadgerr

'Of all the stories I've read I can safely say that this is the one that best combines the written word with sound and music, there are plenty that have tried the same and not even come close to what you achive here.' - Lore

'This is the greatest story I have ever read. This is also now my favorite story. If you don't upload another chapter soon I will wait patiently until you do. I will climb mountains for this story. I will go to Disney Channel.com without my parents permission for this story. If i don't finish this story, i will write down in my will for someone to finish it for me. You, ascended pony writer from a land where the pigeons poop gold, are the greatest person in history.' - Blooming Cherries

'I am loving this story so far. The storytelling, the drama... oh it is so magnificent. A well crafted story by a well deserving author. I tip my hat to you sir. I can see some form of "Beauty and the Beast" in here. But what also surprises me is the way it is written. I've even had some moments of portraying Spike as Holden Caulfield from the famous story, The Catcher in the Rye. Just the way he speaks sort of reminds me of the way that poor man was, and the bits of Spike not wanting to detach from Rarity felt similar in the regards of Holden not wanting to grow up. Again, Pen Mightier, you have done a great job. Keep up the great work!' - XxEpsilonxX

'My cheeks hurt because I been smiling all the way down the chapter. Princess Luna really is the best pony.' - Allen Vth

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.

Featured on Equestria Daily on August 22, 2013.

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.

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

All of Equestria is united in celebration for the return of their beloved Princess Nightmare Moon. But when Celestia and everypony else recieve her she's skeletally starved, filthy, and very nearly dead. Meanwhile, while everypony's eye is turned, a lusty Blueblood pursues Twilight Sparkle, intent on adding her bloodline to his own so his family might step closer to godhood. (Alternate Universe, there never was a Princess Luna)

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?
