Celestia's morning has been difficult enough, between hearing Twilight's confession of love, and then breaking her heart as gently as possible. Mere moments later, her private chambers are rocked by the shockwaves of a time-traveling spell. This marks the arrival of Celestia's alleged lover from five thousand years in the future, Princess Twilight Sparkle—or as she insists on Celestia referring to her, Glitter-Flanks.

Armed with thousands of years of knowledge of which buttons to push and how to make her squirm, Glitter-Flanks has traveled back to this date for one singular purpose: to establish the closed time loop that sets the two of them up as a couple.

Deep in the catacombs beneath the Crystal Castle, Cadence and Shining Armour discover something that brings Luna running. When the moon fails to rise, Celestia follows to investigate.

Alternia, sister to Chrysalis, ruled Equestria for a thousand years, disguised as Princess Celestia, while the alicorn slumbered in a healing sleep. Now revealed, Alternia prepares to become Equestria’s first changeling princess, and prove herself to the ponies she loves at the side of her co-rulers Luna and the newly-returned Celestia.

But even as the crown descends onto Alternia’s head, something is stirring in the depths of the Eastern Sea, something that will turn the surface world onto its head. Some power that could destroy Alternia, and all that she loves, before she can even regain the approval of her own ponies.

Will Alternia restore the trust her ponies once placed with her? Will she found a hive? Will she find love?

All that is certain is that Equestria, and the world, will never be the same again.

Now that Princess Luna is finally back, Princess Celestia finally gets to spend some sister time with Luna. And she thinks she knows just how to do that.

-Extremely short read-

Just because the two sisters have led Equestria through thousands of years of peace doesn't mean there aren't those who think they can do better.

With a powerful artifact on their side, a group of rebels has sealed Celestia in her palace and stripped her of the majority of her powers. As the last of her guards fall, she hears the pounding on the throne room doors and knows the end is coming soon...

**Featured on the front page on 8/12/15; both surprising and flattering seeing as how this is the first thing of substantial length I've posted here. Thanks all!

**Now with a dramatic reading!

Celestia has had plenty of interesting drunken moments. That night with the mule, the time she woke up on pirate ship in the middle of the sea, and who could forget the time she woke up with a pair of wings, a horn, and a fancy tiara. Oh, and a hangover the size of the sun.

Warning: Drunken Silliness and plenty of foul mouthing

So me and Fuzzyfurvert were having a conversation about how it would be funny if we made a fic with a slightly similar idea to Conker's Bad Fur Day. It extended to Celestia being an earth pony who had one too many to drink. So you can blame him for this silliness.

Twilight talks to Celestia about her deceased grandmother.

A snippet of life in story form.

Princess Luna has raised the moon countless times in her life, but tonight was the first time she received a gift and an invitation to Celestia's chambers after doing so. While she accepts, she can't understand why the offer was made. There was nothing special about the day.

But she's wrong. Today was the day the newest letter from Ponyville arrived.
