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injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her.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?

(Sequel to Stardust, familiarity with this is recommended!)
(Proofread by Arzoo!)

(Crossover with XCOM: Enemy Within, though the crossover and human elements are minimal)

In response to threats of a griffon attack on Equestria, Twilight responds with a letter detailing just why such actions would prove unfavorable for them.

Derpy loves her daughter more than life itself. She always looks forward to when her little filly will come home with a wide smile across her face, but what can she do when there is no smile? What can she say when the young pony's bright eyes are blackened and bruised? Sometimes, a mother's wings are all she can offer; sometimes, that's not enough.

Plowpony's Day- a day of peaceful rest and relaxation. Or it was, until Twilight Sparkle badly mangled a teleportation spell. It has left her with a bad case of Horn Rot, a disease that if untreated could prove fatal. What's more, the malady is advancing faster than the slow-brewing potion that cures it!

There is one swifter cure: the Beneviolet, a star-shaped flower that grows in the distant Archback Mountains, far beyond the western borders of Equestria. Applejack, Rainbow Dash, and Rarity choose to undertake the long journey for the sake of their friend. Their path will wind through floes of ice, across gold-tinted plains, into distant forests glimmering with magic. They will learn much about the world beyond their homeland- and much about themselves, as well.

Yes, it's "Dangerous Business," here on FIMFiction. A huge debt is owed to all those who have supported me over the years. I've edited the story some to remove extraneous bolding and italics, but other than that, it remains unchanged. I hope new readers enjoy it as much as old ones did.

Luna drops the soap and what began as an uneventful bath turns into a nonsensical fight for the castle.

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 story is a sequel to Power Surge

Takes place ten years after the events of "Power Surge"

Rejection
There may come a time when the powers we gained so long ago, the skills we fought to refine and keep at their peak will need to be put to the test. That time has come, and Twilight must show that she is ready to push herself to her limits and beyond. For if she does not, everything will be lost.

Thanks to This guy! for the new and awesome cover art

Twilight is outraged by the fact Rainbow Dash has begun shipping Daring Do and Ahuizotl.

"She called me ugly, an ugly pony who lives in a mucky old farm! She called mah bow 'horrid' an' mah mane 'yucky,' an'...an' is she right, Applejack? Am Ah...ugly?"

Applejack teaches her sister a little something about beauty.
