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.

Comet takes his job too seriously. Angel doesn't take anything seriously.

Comet joined to protect kingdom and princess(es). Angel joined for adventure and danger.

Comet isn't interested in mares. Angel can't stop talking about stallions.

Comet is a pegasus. Angel is a bat pony.

Together, this unlikely duo goes through life as Royal Guards from basic training to fully fledged guardsponies. Who knows? Maybe they'll even start to get along.

Kratos...the Ghost of Sparta...

Under the domination of Ares, the God of War, he committed horrid atrocities, including the slaughter of his own wife and daughter...

Visions of what he had done would haunt him all his days...until it brought his days - and his world - to an end...

At least, that's what the fates have decreed await him and Olympus.

But Fate changes sometimes. Some things can't be predicted, even by gods. And this time around, one of those things has found her way to Kratos at the very beginning of his Nightmares.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

My name’s Marcus. Marcus Cortez. I’m currently a freshman at CUFTA. You don’t know what that means? Well, it stands for “Canterlot University for the Arts.” While it is a little unsettling to go to college in a completely different world from my own, and while being a human in a school full of mostly ponies is a little intimidating, I’m doing fine so far. I don’t have to worry about roommates, since I don’t live in a dorm. I live with my aunt.

Her name is Celestia. Princess Celestia.

You’re probably wondering how a human could be the nephew of a pony, and an alicorn princess, no less. Well, it’s quite the story.

In case you haven't guessed yet this is an anthro story, and my first time writing a story in first person, so we'll see how this goes.

The prologue for this story starts sixteen years prior to the return of Nightmare Moon and the story's main events take place after Season 3 ends.

One foggy morning in Ponyville, the residents wake up to find their deepest darkest secrets sloppily written in red paint on their homes. No one knows who the culprit was, the only thing that the town knows is that it will not come off, no matter how hard you scrub. The town is baffled, humiliated, and in shambles. But no more than Twilight and her friends.

In a time where everything you fought to keep hidden is out into the open, will you embrace your faults or sins, or will you let them consume just who you really are?

Time to fess up, Ponyville.

Oh, and Skeeter The Lurker for proofreading.

It had been nearly a year since you won that labor lottery. This job had quickly turned into the best thing that has ever happened to you and your family. From the Grestin checkpoint, you had seen it all; terrorist attacks, long-seperated lovers getting back together, people trying to smuggle drugs into the country...
None of that compares to the day a portal opens to an alternate dimension just outside the walls.
Which is bad, because inevitably that means more papers for you to check and double check.
But still, a job's a job. Might as well keep a straight face about it...
And remember:
Glory to Arstotzka.

We all know how this goes, don't we? Some unlucky schmuck goes to a Halloween party or convention dressed up as someone evil, gets sent to Equestria, and then ends up antagonizing the locals.

Well my story goes a bit differently. My name is Isaac Donohue, and after a night of drunken partying that I STILL can't remember, I wake up in Equestria fifteen hundred years before the events of canon with five seemingly random superpowers:

Angelic Physiology, so I'm frickin gorgeous now. Oxygen Independence, so I don't need to breath. Asexual Reproduction, just call me Mister Mommy why don't you...Bubble Breath, something useless that I rarely use. Power Replication, otherwise known as a game breaker.

So anyways I befriended everyone's favorite draconequus Discord, and we made such beautiful chaos together. Well, it was more of me trying to reform him before he got stoned by the Princesses in an effort to change history for the better. What a waste of time that was, and as a result of this I got petrified as well for being his accomplice. Can you believe that?

Since I'm free, I've decided to settle down and rule a kingdom of my own. I'm sure there are enough tyrants in the world that need to be overthrown despite Sunbutt's best efforts. But if there aren't any, I'm pretty sure I can steal the Crystal Empire from Sombra before Shining Armor and Cadence do.

The only problem is, THE LAW WON'T STOP CHASING ME!

A LoHAV story that I'm writing as I go on.

ANNOUNCEMENT 6/4/2017: I'm sorry, but this story is cancelled. This has been a long time coming. As I've progressed as a writer I look back on this story with increasing amounts of disgust. Still, I know people enjoy it for some reason which is why I'm leaving it up for posterity's sake. Maybe I'll completely rewrite it from the ground up in the future, but that time is not now.

After a tragic accident, a human ends up in Lord Tirek's body, as part of an attempt to reform the villain after his recent escapades. While the hero of our tale is trying to make sense of his new surroundings, the rest of Equestria thinks that the most terrible threat that their world has ever seen is back...
And the powers that be are definitely not happy about it.
