The force of its death knell shatters Mount Arreat and sends Tyrael hurtling across the endless planes of reality.

Wounded and near death, hope appears in the form of two strange creatures bearing the power of night and day.

Tyrael now faces a time of recovery as his power slowly heals within a body fashioned for him by his saviours. Justice Incarnate tastes for the first time the life of a mortal, and it is a strange, confusing experience .He has been left in the care of one Twilight Sparkle to learn of this world.

After all, where better to find peace and harmony than Ponyville?

This story is a sequel to The Best of All Possible Worlds

In school, everypony learns about the official history of Equestria, the acts of heroes and villains that made the world what it is today. But at home, everypony learns another, secret history, about how their family and theirs alone is at the center of Equestria's history, and how without them, the world will fall apart. This Hearth's Warming Eve, Twilight Sparkle and their friends will share their secret histories, and in this way discover that the bonds between them reach back far earlier than Rainbow Dash's first Sonic Rainboom.

This is a follow-up to my earlier story, "The Best of All Possible Worlds". That story was set centuries in the past, while this story is present day. If you're wondering where the humans came from, see another side story that is otherwise unrelated to this, "Parade Coverage". Despite that, I expect that this story stands alone. The story's set in an alternate-universe Season Three that branched off early in Season Two.

The royal court of Canterlot welcomes its newest member with open forelegs: the human philosopher Voltaire, from Earth.

On Earth, Voltaire is known as the greatest enemy of tyranny in the history of literature, and a legend in his own mind.

On Equestria, the court betting pool is giving him a week before the Princess banishes him to the Moon.

Note: This story doesn't have sequels per se, but there are a couple of short follow-ups set in the present day ("Parade Coverage" and "Secret Histories"), and a prequel of sorts in "At the Inn of the Prancing Pony".

A Spartan of the UNSC falls into Equestria and has various shenanigans in the land. First chapters revolve around how he meets the royalty, the mane six, and the new world in general.

Celestia and Iroh share some afternoon tea and sagely advice over a game of Pai Sho.

Credits for original idea and editing go to my good friend Cthulhu.

Iroh is a character from Avatar: The Last Airbender, in case anyone didn't know and was wondering.

==Originally written Fall 2011== Equestria Daily Post==
After a long day of ruling Equestria, the Royal Sisters need a chance to unwind. Luna's solution is a few glasses of her once famous Moonshine, a drink distilled from moonlight. Celestia has been sober for a thousand years, but the temptation to have "just one" glass proves too great. Yet, when that one glass turns into several, it's Twilight who will have to deal with the princesses when they’re drunk off their flanks.

King Sombra’s dark influence was obliterated by the Crystal Heart, and the villain is well and truly dead. But when he attempts to steal the afterlife of an innocent victim, a human spirit is left hurtling towards Equestria, where this unfortunate soul is revived into the only vessel available: the reconstituted body of King Sombra himself.

Thus, a cheerfully oblivious alien is crammed into the form of the most evil and malicious being Equestria has ever known. Not that Shining Armor and Cadence know this, of course. As far as they are concerned, the King is back and he’s lost his fricking mind.

The Lone Wanderer has been known as the man who shouldered the nightmares of every man, woman and child in the wasteland, so that they may live. But when the Wanderer was once again abducted by aliens, he found himself falling, quite literally, into a whole new wonderous world, untouched by the horrors of nuclear devastation.

He has been facing other people's nightmares constantly for almost a decade, it was high time he was allowed to wake up.

Meanwhile, the ponies of Equestria are baffled by a strange object that fell from the sky.

Fallout/FIM crossover. HiE. T for violence and some language.

Now with a TVTropes page!

The Shaper is a smith of unparalleled skill, her creations the most sought after in the fallen world. When a pony named Lyra comes to her with a unique commission she has to put all her skill to the test to craft a weapon of great power. For Lyra's goal is not an easy one, and it is not just any weapon that can kill a Dragon.

A story inspired by this and this image, as well as this challenge by CDRW (whose fic A Still More Glorious Dawn Awaits is quite good).

You'd think that being trapped in stone would mean that, if nothing else, I could get some peace and quiet. Unfortunately, it seems that Celestia has other ideas.

She has appointed these ponies... these 'Keepers', as she calls them, to keep me entertained during my incarceration.

Honestly? I'd prefer the boredom.
