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.

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."

This takes place between Chapter 21 and Chapter 22 of Jake and the Kid, and while it establishes certain events, you don’t need to read it to keep up with the parent story, and outside of some inside jokes, will not affect the plot of the principal story or any sequels.

Contains BDSM references, but nothing I would consider clop. No graphic depictions of hot and sweaty activity. Not that there is anything wrong with that.

I've decided to change the rating to Teen/sex, because there isn't any clop. Just a lot of talk about clop, sort of, and I think I may have gotten some down votes for misleading advertising. -_-;;;

A young human girl runs away from home with her best friend, and finds herself much further from home than she ever expected. Her arrival in Equestria will cause ripples that affect ponies from the lowest to the highest.

Meanwhile, a young Nocturne mare begins an epic quest to earn the right to clean Princess Luna's porcelain throne.
Be sure to check out the Continuation. "How to Train Your Batpony" Not a Clopfic!

Let me extend thanks to Georg for letting me play with some of his characters and situations, and for proof reading and contributing some really good lines here and there.

Secondly, I would recomend reading some of his stories to better understand the jokes and situations that pop up in my story. Most especially I would advise you read A War of Words - The Opening of the Guard and possibly Genealogy (or the mating habits of Nocturnes Pegasi) (which is very long)

This story is a sequel to The One Who Got Away

A frustrated young orphan colt with a talent for painting is determined to run away from his dead-end rural village for the distant cultural haven of Baltimare. All he needs to do is slip aboard a raft and drift down the river Fen until he reaches his destination. It’s a simple plan, and would have worked just fine except for one thing.

Seaponies.

This story is a sequel to The Cadenza Prophecies

Princess Flurry Heart inherited her mother's beauty and grace as well as her father's strength and bravery. The Empire couldn't hope for a better or more suitable heir to the Crystal Throne. Everypony in Equestria admires her and thinks she will be an ideal ruler.

They're wrong.

Young Flurry Heart has no interest at all in being a prim and proper princess, and would much rather have wild and dangerous adventures like her Aunt Twilight.

Book 5 of the Alicorn Adventure series.

This story is a sequel to The Luna Cypher

Also, there are sky-pirates!
