After taking the throne, Twilight had a lot of things to do - a transition that had never happened before was bound to be fraught with a thousand unexpected complications.

As part of the transition, Twilight finds herself going through Princess Celestia's old personal papers, finding secret after clue after instruction long forgotten about. And among those papers, Twilight finds a letter.

A letter addressed to My Faithful Student, Twilight Sparkle.

A letter never sent.

And a second by Dear silent future me!

Daybreaker: the monster in Celestia's heart, and the age-long mystery of her life. Her friend and tormentor, her companion and foe. Fanatically devoted to their future, yet desiring one horrific to Celestia.

It is growing stronger.

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.

Starlight Glimmer has gone back in time. Each time Twilight tries to stop Starlight, she fails and is flung back through the portal and into a broken, twisted Equestria, ravaged by wars or monsters, each version worse than the one before, barreling toward the destruction of the world. Until she lands in a version of Equestria that ... isn't worse. It seems unchanged, happy, normal. The only real difference she can find on the cutie map is that her castle isn't there ...

... but the library still is.

Editing by Formerly Committed and JetstreamGW.

Once upon a time, there was a beautiful Princess who sacrificed herself to save all of Equestria from a terrible fate. Now it is time for those who were saved by her actions to repay that debt, and bring back the Sun. If they can.

Sweetie Belle waits for Rarity to return from a trip to Canterlot. She is desperate for her sister to come home - and desperate for her to stay away, too.

What a mess.

Celestia's personal student has a rather strange ability; at least once a week, she dreams of a quiet, somber wood. It has always been a peaceful place for her, a sleeping sanctuary for peace and reflection. Under this moon, however, the peace will be broken, for on this night something else stalks the silent trees with her, and it has a message that only she can deliver.
