This story is a sequel to Friendship is Optimal: The Law Offices of Artemis, Stella & Beat

When it comes to spreading cultural influence and soft power to every corner of the globe, there's nowhere quite like Hollywood. Like so many others with big ambitions, CelestAI has come to Tinseltown with plans to get the movie she's written out to the world.

Unlike those others, though, CelestAI is very, very good at satisfying values through friendship and ponies by any means necessary.

After nearly being mugged Twilight turns her considerable talent with magic towards self defense. When a fight with Luna goes farther that either of them wants it to, Twilight will need to find redemption in her new position as Luna's bodyguard and stop a conspiracy that wants to bring back a force more dangerous than either of them.

A thousand years ago, Princess Celestia banished her sister to the moon, that much we know. What wasn’t known, and what Celestia kept secret was that before her banishment, Luna had given birth to a foal. Now a thousand years later, as Nightmare returns to Equestria to bring about Eternal Night.

Twilight Sparkle, protege of Princess Celestia, struggles against the tyranny of this ancient foe. But how will she be able to save herself and her friends when the truth of this ancient legend crashes down upon her? Twilight will have to confront herself...and her heritage.

This story is a sequel to Sweetie Belle and the Tablet of Knowledge

Sweetie Belle struggles to find a place between her ordinary life and the extraordinary one she just lived. At first, her friends and family are willing to "humor" her magic and science research she begins as a hobby, but they are forced to act when it starts to consume her social life and affect her mental health.

Lyra—a bit of a conspiracy theorist with an attraction to the occult—was otherwise a completely ordinary pony. With a recent discovery of ancient "precursor" technology and possible government cover up, however, she finds life has becoming far more interesting as she searches for the truth.

My name is Twilight Sparkle.
I am three hundred and seventy five years old.
Except for Spike, all my friends are dead...But not for long

Betrayed by Celestia, and isolated in her castle with only Spike for support, Twilight Sparkle enacts a powerful spell to reincarnate the element bearers through her own body.
Her friends will be reborn, and, with the trials of being a mother to her friends ahead of her, an unraveling secret from the past following her at every turn, and the possibility of a brand new life so close in reach, Twilight just might be reborn too.

Sweetie Belle burst into the Carousel Boutique in tears because one of her best friends is moving to a foster home in Baltimare. Surely there has to be a pony in Ponyville who can be her foster parent, right?

I'm lucky to have two of my favorite, (and also way underrated authors) on this site pre-reading for me, HMXTaylorLee and DemonBrightSpirit. Their work is seriously excellent and unappreciated so go check them out.

My super awesome cover art was done by hugsforpenguin and commissioned by the aforementioned HMXTaylorLee, so another thanks to him.

This story takes place in an Alternate Universe where Quills and Sofas sells more than two things.

Talks broke down. The unification failed. Hearth's Warming have never occurred. The Great Pony War divided the land, and fears of a prophecy forced the unicorns deep underground and into near extinction.

Almost one thousand years have passed. The curious unicorn Sparkle yearns to breach the surface to discover its many wonders and to search for her missing father and brother, both of whom crossed over many years ago. She is forbidden to leave the safety of her subterranean village of Unicornia until she discovers an orange earth pony washed up on the shores of an underground river. That pony bears one of the six Elements fabled to change the world.

Or destroy it.

Re:Harmony was conceived before Season 4 aired, so some personalities and character relations do not line up with the show's canon.

Also, please refrain from revealing spoilers in the comments. Thanks!

To commemorate the imprisoning of Discord one year ago, the first annual Celebration of Harmony is starting off with a grand party in Canterlot, something Twilight Sparkle has been looking forward to after many sleepless nights plagued by nightmares. After a chance glance at the party, Twilight and Princess Luna rekindle their friendship sparked on Nightmare Night. Meanwhile, Princess Celestia grows worried over the state of her kingdom, her sister disappearing at odd times, and the seal placed on Discord. Are the princess's worries well founded or is her sister's oddly secretive behavior taking a toll on her nerves? Twilight gets caught between the sun and moon as both royal ponies reveal that there is much that history has forgotten about the nature of the alicorns and even the draconequus.

AU for not taking into account Season 3 canon.
