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.

Crystal Leviathan

Pandinus Imperator (You can call him Pan, he won't mind) is knocked back in time during the Canterlot Invasion, and accidentally kills King Sombra on arrival. Instead of being executed, the changeling is surprised to find himself being hailed as a hero, and is promptly put on the throne as the new monarch, the Crystal Emperor. However, Pan now faces a great many problems, among them Celestia and Luna, who seem certain that the changeling is secretly up to no good, as well as several political factions secretly plotting to undermine his reign. There's also the tiny problem of the constant snowstorm that threatens to cut the city off from the outside world permanently.
The Crystal Ponies need a hero now more than ever before. Why did they get a changeling instead?

While not truly a part of Bucking Nonsense's Changeling-Verse, the same rules regarding changeling abilities and society apply.
