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."

It took many long years and far more defeats than he'd care to admit, but at last—at long last—victory was finally within the great Ahuizotl's reach. Absolutely nothing, not even that meddlesome Daring Do, would be able to stand in his way any longer. Yet even with his arch nemesis facing her inevitable demise and the ultimate power literally in his grasp, he can't shake the feeling that he's forgotten about something.

One tiny, crucial detail. Something very important. As in, 'could easily ruin his plans if not attended to' important.

...

Eh, maybe he just left the oven on again.

This story is a sequel to Stardust

Twilight has finally returned home from the harrowing challenge that Discord set upon her, and the residents of Ponyville and the Elements especially look forward to having their dear friend returned to them.

Twilight, however, has changed. Still suffering from her injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her. Will her frustration at her current state and her friends inability to understand her experiences cost her what she valued most before Discord's bet?

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.

Brought to you by Loyal2Luna, this new Downloadable Content for Mass Effect 2 brings the fight to Equestria.

Just about ready to embark on their mission to stop the Collectors from further abducting human colonies, Commander Shepard and the crew of the Normandy SR-2 are given a new priority, when the Illusive Man tasks them with investigating the mysterious disappearance of a Cerberus science team.

Soon, what begins as a simple search-and-rescue unveils a mystery millions of years in the making, and the Commander finds himself thrust into a situation he couldn't possibly have prepared himself for.

Join the Hero of the Citadel as he uncovers the secrets, combats the demons, and ultimately decides the fate of the impossible world known as "Equestria."

In 2185, during his campaign against the Collectors, Commander Shepard discovered a previously unknown species whose origins predated any other race in the modern galaxy. Following a daring rescue from their ancient sanctuary, the Equestrian Herd was brought back into the galaxy where, for the first time in eons, they must walk their own path.

Knowing full well the terrible threat that lingers on the edge of the galaxy, the leader of this newly freed race fights to secure her people’s future while attempting to prepare for the storm on the horizon.

This is her story.

Tiberium. The infamous green crystal that destroys entire worlds in its wake of global proliferation. It has been a little over a century since the Tiberium threat was first wiped out on Earth, and with it, the primary vestiges of the Brotherhood of Nod. When the GDI advanced humanity to the stars, they found that Earth had not been the only target of the alien Scrin: dozens of other worlds had already been claimed by Tiberium, and the Scrin returned in full force, attacking human colonies across space, stopping human expansion. To fight back, the GDI undergoes a reformation to become the Interstellar Defense Intiative (ISDI) and enacts the Hallman Directive, designed to stop Tiberium spread wherever it may be; such a protocol brings the reincarnated ITC Methuselah to a planet being ravaged by the green crystal, and the forces under Commander Martin Alexandra deploy to stop the threat.

Commander Shepard remembers firing the crucible. She remembers she had to make an important choice. She remembers good friends, a lover, and plenty of loyal crewmen.

She just can't remember what her choice was. What the threat she was striving so hard to end was. Or what the faces of the most important people in her life look like.

She also has no idea how she wound up in the monster filled forest she's come to call home for the past eight months. Or how she picked up a snarky A.I. making its home in her omni-tool.

After a mishap involving the Transportalponder, the Courier finds himself in a place he doesn't recognize. With no way back and nothing else to do, he decides that wandering into the nearest town is the best option. Being the Courier, things aren't that simple...

A Fallout: New Vegas/My Little Pony: Friendship is Magic crossover

The style alternates between omnipresent third-person and the Courier recounting his tale to... Well, take a guess.
