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.

(XCOM/FiM Crossover)
(Sequel to Stardust, which I recommend reading before starting this. Fortitude Amicitia and Broken aren't required reading but are supplemental to the storyline)
(Gore tag for blood and violence)
(Alternate Universe tag because of the divergence from canon that Stardust has caused)
(Uses elements of Season 4)
(Coverart produced by the amazing Carnelian!)

This story is a sequel to Stardust

When Equestria’s newest member of royalty asks for aid to be offered to her friends from abroad, the best and the brightest volunteer to serve. Captain Steel Song of the Dusk Guard are immediately mobilized to help XCOM defend their world from the enemies that besiege them. However, their first joint operation with the humans takes a turn for the worse and they quickly find themselves fighting for their lives against the full force of the monsters that threaten Earth.

Ponyville is getting ready to host a Dodgeball Tournament when Gilda shows up, challenging them against her own team. As they prepare themselves, Twilight and her friends learn a surprising secret about a certain crossed-eyed mailpony. Will Ponyville be able to beat Gilda and her team? Or will they taste rubbery defeat?

It's summer vacation, and Dinky Doo just finished the last fantasy novel in the house. Bored out of her wits, she starts acting out her own fantasy story. The other kids in the neighborhood gradually join in, however things quickly get out of hoof.

(Formerly a collab with The Dinky Society, Now moved to my page as I am the only one working on it now.)

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 is Frosty Winds. I was just your typical, rank-and-file Enclave scout. I had an ordinary life, living in contentment among my loving family and good friends. Things were good.

At least, I'm pretty sure that was the case; I honestly can't say for certain anymore. One moment, I was being recruited to take part in a routine Wasteland scouting mission, and the next moment I wake up as a prisoner of the Steel Rangers.

On the bright side, I’m not missing much. Just all of my memories. And my left foreleg. Nothing important, really. Pile on a disease I’m not vaccinated against and being a few clouds short of a weather system probably doesn’t make any of this much better.

As if that wasn't enough, apparently I made a deal before I lost my memories. If I don't complete my task I agreed to within a month, I'll die. Of course, it would be helpful if I could remember what the agreement was.

So here I am, floundering aimlessly about the Equestrian Wasteland. I have absolutely no idea what happened, what I should do, or how to uncover the secrets that lie within my stolen memories.

Help. I need an adult.

This story is a sequel to The Dresden Fillies: Strange Friends

Almost a year has gone by for Harry Dresden since he left Equestria. He'd have written, but between saving his newly discovered brother and destroying a scourge of vampires he's been a little busy. Then out of the blue he receives a strange letter from Twilight asking him to return. With no cases at the moment he eagerly accepts, but his friends aren't the only ponies expecting him. There's been a lot of rumors since his last visit and some ponies aren't too keen on seeing him come back.

A sequel to The Dresden Fillies: Strange Friends.

My name is Aideen; I know, I know, it's a stupid name for a pony, and if you pronounce it wrongly it even sounds male, but let's not get sidetracked here. I've lived through multiple mental breakdowns and severe physical beatings, but who hasn't in the dear wastelands? I can, however, claim that I'm a unique nutcase; there's something that differentiates me from the regular nutcases out there: The same evil entity that transformed Princess Luna into Nightmare Moon once upon a time wants me to be her new host.
Uhm... fun stuff...

Rated teen for gore
