On the eve of Hearth's Warming Eve, as Luna raises the moon, she is visited once again by the very entity which drove her to madness. Resisting it's influence, Celestia and Luna hatch a plan to end this once and for all.
One which works too well with unforeseen consequences.
As the nightmare loses it's power, it plummets to the earth followed by an explosion of Power that the Royal Sisters know too well. However when they find the epicentre of the explosion they are shocked to see an Alicorn with no memory, and no name.

Yet the question remains. Why does it resemble Luna so much that they could be twins??

Follow the story as this unnamed Alicorn makes her presence into Equestria, for better or worse.

Luna has had enough of Celestia's games, and has found the perfect means of revenge. Using a long-forbidden spell, she transforms her sister into little more than a small filly, all so she could pull the greatest prank ever. Unfortunately, she soon learns that before you fool around with dangerous magic, you really need to read the fine print...

A sequel can be found here.

A meeting of some fanon incarnations of Celestia.

Luna is a hardcore gamer, and it piques Celestia's curiosity. She's skeptical at first, but Celestia is willing to learn about Luna's favorite pastime.

Celestia agrees to allow Twilight to spend the night at the palace per Luna's request. But as it turns out, the two ponies have other things in mind other than a sleep-over...

It's been more than a year since Princess Luna's return to Equestria, and she is making great strides in her language skills. And along with this come a slew of new writing skills.

However, Celestia may have a few objections once she finds out just WHAT Luna has been writing...

Twilight Sparkle is summoned to settle a legal matter involving The Great and Powerful Trixie... What in Equestria did she do now?

This is the story of ponies; ponies in panties.

Her beauty, sullied; her wisdom, corrupt; my love for her, violated. But still I answer...

Summoned to the palace in the dead of night, Twilight takes up a burden that even her generous, loving soul may not be able to handle...

Humanized Twilight/Tyrant!Celestia.
