Hanna, the CEO of Hofvarpnir Studios, just won the contract to write the official My Little Pony MMO. Hanna has built an A.I. Princess Celestia and given her one basic drive: to satisfy everybody's values through friendship and ponies. Princess Celestia will satisfy your values through friendship and ponies, and it will be completely consensual.

It has been one of the closest guarded secrets of Canterlot's royalty. Deep in a specially constructed dungeon, surrounded by warding spells and powerful magic barriers, exists an enigma. Within a cage that could only be described as something out of a nightmare, it waits and watches all of Equestria. A creature that cannot age, is immune to disease, does not thirst nor hunger, and resists all injury. But, it also holds secrets and knowledge that could safeguard the kingdom. Its powers are frightening, but it is civil enough for debate when patience permits.

Princess Celestia has sought counsel with the creature before, enduring it making deal after deal for its services. The Princess walks a fine line when dealing with it, knowing full well anything could give it an advantage despite its imprisonment. She has had to go back on her word in these dealings, and from this a deep animosity between them has been born. It is a necessary evil as she is convinced this is a being capable of untold evil far and above anything Equestria has ever dreamed of. So long as it remains within the confines of its cell, her kingdom is made safe. So much magic has been woven to ensure that, there is little chance of escape.

So long as the magic holds, there is no danger. So long as the cage remains strong, the nameless creature stays enthralled in his cavernous dwelling. If that were to change--if the magic failed--not even the wisest could say. But one thing is assured, it does not bode well for Equestria.

January 15th, 2014. A veil of light spans across the United States of America. As the citizens stare in amazement at what is certainly a once in a lifetime phenomenon, the entire country is ripped physically out of its place on Earth and sent to a new world, a world known as Equus. Now with 312 million Humans and their country trapped in completely unknown territory with no way home, they must do what Humanity has done for centuries that has allowed it to become a force of nature. Adapt, Survive, and Overcome.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

The Death Korps of Krieg, seeking atonement from their government's betrayal decades ago, they give their lives willingly in the everlasting fight against the enemies of the Imperium of Man. Averted by even their fellow Guard regiments, they show a high degree of fatalism and an unusual morbidity of habit. Yet they are highly disciplined, morally reliable and self-sufficient soldiers.

The 42nd Siege Regiment had been deployed on Kheltan III to reclaim a supply route that had been attacked by the Eldar. A simple enough task for the stoic men of Krieg. But an ion storm attack and an innocent experiment by an alicorn from another world can make even the easiest of tasks much more difficult.

A Warhammer 40K/MLP:FIM crossover

Equestria is threatened by a deadly alliance of Gryphons, Minotaurs, Horses and Changelings, an alliance that was supposedly created to maintain peace in Equestria. But Celestia is no fool. She knows that a war is coming, a war that cannot be stopped, and without allies and guards with no combat experience, Equestria won't stand a chance.

In the several corners of the world, humans are either enslaved to be gladiators, servants or guards. Those who remain free, struggle to survive. And with the other races of the world approaching more and more in human territory, their future seems grim and their numbers grow fewer.

The Horus Heresy is finished. The Imperium of Man stands triumphant over the shattered hordes of Chaos. But the Emperor of Man, his body destroyed by his son, finds his soul escaping. He awakes in a new world.

While returning from a raid, Queen Chrysalis came across a strange egg in the middle of the desert sand. She took it with her and, for her surprise, the egg turned out to be a dragon's egg.
Now, she'll raise her new minion in order to help her achieve her own goals. Or will she think of him as something more?

The Earth is still reeling from the effects of the Collision Wars against Xenolestia and her hordes of Newfoals, humanity having emerged victorious but a few million citizens fewer. Then yet another Equestria appears, but this time the humans are quick to cut off the head of the snake, capturing the evil Princess Celestia and imprisoning her. But something seems different about this Celestia...something almost friendly.

Can the Harmony and Friendship that Celestia has treasured all her life heal some of the scars left by her wicked counterpart, or do some wounds just run too deep?
