Twilight looked over to her dear mentor, Princess Celestia, and found she had once again fallen asleep mid-lesson. Her intense debate on awakening the princess was cut short when the decision was taken out of her hooves.

“Huh? Oh. Twilight, I am so sorry for falling asleep again. I think we need to reschedule this for tomorrow morning.”

Twilight nodded. After all, Princess Celestia was obviously overworked. If only there was something she could do to help.

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.

Just something I threw together over the last two days for Christmas. Enjoy.
Uses characters from and is part of The Dusk Guard.

I am Starswirl the Bearded and my story does not start in Equestria. Many have heard the rumor that I am from a foreign land. This is but the smallest part of the truth, for I was not born a pony but on another world, and brought here by Princess Celestia on a mission to save my race. I was born a human, in the year of my people 1452, and my name was Leonardo daVinci.

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?

Yeah, really bad Hearts And Hooves Day.

It was a night like any other in Ponyville. It was, until a shooting star turned into a burning streak that roared overhead before crashing off into the distance. At first it looked like a meteor. But then it had turned, quite sharply, and flattened its trajectory, sailing uncomfortably close to the treetops.

Twilight Sparkle had dismissed the idea of visitors from beyond the stars as pure fantasy, the type of pulp novel that Rainbow Dash seemed to enjoy. Now it was a frightening possibility, and now nothing could ever be the same.

Unbeknownst to her, the accidental visitors to Equestria are just as frightened. Laws of physics that had long been understood and mastered have broken down, leaving them trapped and sitting on a possible ticking time bomb on this strange fantasia of an alien world. As utopias collide, both are faced with an event outside all comprehension, events which civilizations rarely encounter more than once, and generally the same way as a sentence encounters a full stop.

A crossover with The Culture series by the late Iain M. Banks.

Clover the Clever has found a love so pure and true that no pony can stop it. But even the greatest love cannot conquer death itself.

So Clover will keep looking until she finds something that can.
