Celestia and Luna have ruled in Equestria for over a thousand years. Their age along with the unbelievable power that they wield to move the sun and moon has caused most ponies to see them as gods.

But as powerful as they are, gods they are not. For the being that has arrived in Equestria has powers that can rival and surpass their own. He is a deity millennia of years old, a deity who commands the thunder and lightning with an incredible might and a hammer that can shatter the sun and moon.

And Celestia and Luna will learn that they are not all powerful. That they are not as mighty as they believed. They are not gods.

They are not Thor.

The surface isn't safe anymore.

In the ruined depths of Canterlot, a team of brave salvagers discover six mares, long forgotten but miraculously preserved. Though these mares cannot remember what happened to their world, they possess powerful magic that hasn't been seen for centuries.

Now the Elements of Harmony are thrust headlong into a world beyond recognition. Twilight and her friends must dive into the sunken remains of history to determine what happened, but Equestria isn't the harmonious land it once was. Before they can focus wholly on the past, they may first have to survive the present.

It isn't going to be easy.

Celestia and Discord, as teens, flee their destroyed homeworld to a new world promised by a letter from Luna. But Discord can't escape his nature, nor Celestia her memories. Being a chaos mage on a starliner is a death sentence, and yet, Discord has to keep using his mind-control powers to take Celestia's emotions away, at her request, because otherwise she wants to die. And Gray Celestia, the discorded Celestia with no emotions but the drive to protect herself and Discord, will do anything that needs to be done to save them both.

Warnings: suicidal ideation, consensual mind control that's still kind of messed up, genocide, a near-execution, mass murder, and comforting lies.

Cover art is by ponkamena/polkahorse, who now goes by ashiida (link goes to their new deviantart account). The source link goes to the derpibooru version. This was the closest I could get from all of derpibooru, though in the fic they're both much younger than the art would suggest.

For years, Twilight Sparkle and Queen Chrysalis have been at each other's throats. Both have experienced victory over the other, and both have experienced defeat. Out of all the creatures in Equestria, none despise each other the way the pony Princess and changeling Queen do. They seemed destined to remain locked in battle forever, or at least until one is finally dead at the hooves of the other. The cruel insults, the vicious loathing, and the powerful spells that have passed back and forth between them at each meeting have become the stuff of legend.

Imagine Twilight's surprise when she finds out changelings consider this dating.

And now they're married.

Some beautiful fanart of the end of chapter three was done by Dmann892; you can see it here.

More awesome fanart, this time from chapter one.

Now with a TvTropes page (obligatory TvTropes warning goes here).

If you want a Russian translation, you can find it here.

There is now a reading of the story on Youtube, which starts here.

Any place where a earth pony has touched the ground. Any spot where a unicorn has used magic. Wherever a pegasus has flown through the air. With the help of a newly discovered particle that reveals how magic affects the physical world, Twilight can track the actions of all kinds of ponies. However, an unprecedented wave of crime is starting to sweep across Equestria, and a common link between many of the cases indicates the existence of a dangerous new foe. Someone who can perform impossible feats without using magic at all. Can Twilight's cutting edge science compete against a criminal mastermind who seems to have no limits?

Equestria is a land of magic and harmony, a peaceful realm ruled by immortal and benevolent monarchs. At what cost is this possible?

Following the discovery of a strange and powerful device, Twilight Sparkle is whisked away to the edges of a land she thought she knew so well. Here, surrounded by ponies whose very existences have been kept secret, she must contend with vicious enemies, hostile allies, and the truth.

Once, I was alone.

I felt neither sorrow nor joy at this. The presence or absence of others meant nothing to me. The universe moved in silence, and I drifted in its flow.

Then came the song.

The gryphons were not always monsters. That came later.

In the earliest days, they were our friends. They flew alongside pegasi. They shared the land with earth ponies. They studied beside unicorns. There was no fear between us. That came later too.

Time drew our people apart, but it was not time that made them monsters. They made that choice themselves; they chose their fate. And it was the greatest gryphon who sealed it.

He was born, many years ago, on a mountain far to the north...

North of Canterlot, in the far marches of Equestria near the border with the Griffon tribes, there is a mountain that flies.

West of Canterlot, beyond the Galloping Mountains and a desert painted in the pastel hues of a faded rainbow, a tower sits at the edge of the world.

South of Canterlot, past the Everfree forest and the desolate badlands, a city of gardens waits to be born.
