This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

On July 17th, 2023, satellites around the world began to pick up a strange radiation source coming from the North Pacific, just above Hawaii. Just as the US, Japan, Australia and other such nations along the Pacific begin to investigate, something covers the entire North Pacific in blinding light, a loud crack rippling through the air. When the light finally died down and humanity rubbed it's eyes in shock, they saw none other than Equestria.

The first contact had gone well enough, with pony and human delegations meeting in New York, Celestia herself showing up for a moment. They claimed that the appearance of Equestria was purely accidental, a 'magical mishap' as they put it. They established 'Conversion Bureaus' around the globe, establishments for the sole purpose of permanently changing a human into a pony.

As it turned out, this was all a ruse. Shortly after the final conversion bureau was built, Celestia herself declared humanity to be a 'vile' and 'unfit' species, citing examples such as their wars, their pollution, and so on. All at once, the Conversion Centers released hordes of Pegasi and Unicorns, bent on forcibly turning all of humanity into 'peace-loving' ponies.

All at once, millions of humans were transformed. Military bases sabotaged. The world couldn't even get a missile out of the ground in time, much less perform a coordinated counter-assault. Humanity simply wasn't prepared for this.

But as it turned out, there were other players in the game. Humanity had gotten out of fixes much worse than this before, and they didn't even realize it. Organizations, unknown to even the world elite, sat beneath the surface of the Earth or disguised as ordinary facilities, prepared to do everything in their power to prevent the extinction of humanity.

As humanity panics, the SCP Foundation takes action.

A normal end to a normal day -- at least, that's what it was supposed to be.

But it wasn't.

Luna went to raise the moon as usual, but something went wrong. Terribly wrong. She felt it, but she couldn't stop it.

None of us could.

It appeared too suddenly -- acted too quickly.

The only warning we received was a roar and a bright flash of light, then everything was gone. No more Canterlot, no more ponies, no more anything.

Nothing survived.

Nothing... except for us and whatever 'it' is.

We may be immortal beings, but that doesn't make things any better -- if anything, it makes the pain all that much worse. The only thing we can really do now is try to avenge those dear to us. Our subjects... our families... my friends...

Everything.

I don't care how long it takes, and I don't care if it's a pointless battle. All I care about now is making sure we put that thing down for good.

After that?

Well...

When Fluttershy went to bed, she was a normal mare. When she woke up, she could see numbers floating over everypony's heads. They were timers, each one counting down to some unknown event. Most ponies had timers that wouldn't end for years, some for many decades. But everypony had different numbers.

So why does Rainbow Dash's timer end in three hours?

Princess Celestia will at last get a taste of Twilight Sparkle. No, not in that way! The whole Elemental Harmony Squad is involved... no, still not in that way!

Popsicles will be prominently involved... and again, not in a naughty way. The only naughty pony here is Luna.

A fellow pony notices that Princess Luna may have a serious problem: there is a small, sentient race inside her mane and they have been living there for quite some time. Luna must decide what to do about this.

A random short story I made to help bring the smiles.

"Suppose I killed them all?"

In an alternate timeline, Twilight Sparkle never became an alicorn princess. Instead, Star-Swirl the Bearded's spell and the Elements of Harmony brought about the end of her life. Two months later, her friends and loved ones are still in mourning from her passing. But just because Twilight's dead it doesn't mean her friends don't see her anymore...

Cadance, Princess of Love.
Celestia, the Lightbringer.
Twilight Sparkle, Princess of Friendship.
Luna, Mistress of the Night.

Of the Four Princesses, Luna is the one that the Four Demons know the least about. Sure, there was that business about being Nightmare Moon and being banished for a thousand years, but how threatening can the Princess of the Night - a princess that plays second fiddle to her elder sister - really be?

Luna isn't insulted. She prefers her enemies stupid anyway.

The fourth and final story in the Four Princesses, Four Demons series, following up Cadance the Unbroken, Celestia the Indomitable, and Twilight the Triumphant.

Luna, Mistress of the Night.
Cadance, Princess of Love.
Celestia, the Lightbringer.
Twilight Sparkle, Princess of Friendship.

Of the Four Princesses, Twilight is the one that ponies know has it easy. Chosen by Celestia, hero several times over, surrounded by friends that would accompany her to the the bitter end. Being a princess was just the cherry on top, right?

Twilight doesn't see it that way.

The third story in the Four Princesses, Four Demons series, following up Cadance the Unbroken and Celestia the Indomitable.
