Unhappy that her future as a member of the monarchy is denied by Celestia, Sunset Shimmer escapes through Starswirl's mirror into another world, planning to take it over to prove once and for all she was fit to rule. What she didn't expect—besides a species change—was to arrive in a world already conquered.

WARNING: CONTAINS SPOILERS FOR THE WHOLE STORY: TIMELINE

This story is a sequel to Fizzlepop's Wish

As a new year starts around Equestria, Grubber is settling into his new life in Ponyville, wondering how he can best help out with Fizzlepop's routine around the castle, with some sound advice from the Princess of Friendship's assistant.

Prince Blueblood is absolutely convinced that Tempest Shadow has lied to Princess Celestia and that she is still plotting to conquer Canterlot. Now it's up to him to stop her.

Unfortunately, he is (a) dead wrong, (b) not a fan of comic books, and (c) not trained in espionage, counter-intelligence, special operations or anything else that would be useful in such a situation. But he does know which flowers go well with her coat and what restaurant can offer the best candlelight dinner opportunities, so... that's... a start...?

Prince Blueblood / Tempest Shadow, because I love my random and obscure shipping constellations these are two very different, very fascinating characters who can probably learn a lot from each other. (Also maybe some Capper/Celaeno on the sidelines later on?)

Content warning is again on the "better safe than sorry" side: there is no suicide, and the only reference to self-harm will be when some of Tempest's scars are discussed.
Took out the warning label for the time being. If I or others feel now or at a later time that it should go in again, it'll go in then. Thanks to the commenters so far for the feedback on when to include it!
Also a mild spoiler warning since this takes place shortly after The Movie.

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)

[ Inspired off Season 5 Finale - Nightmare Moon Verse ]
Social reject, blank flank, and failed candidate for Celestia's School for Gifted Unicorns, Twilight Sparkle's life couldn't get anymore depressing even if she tried. Yet still she looks to the other things in her life to get by, such as her job selling donuts at Joe's Bakery, her best friend Smarty Pants, as well as her inspiration to someday be as great as The Great and Powerful Trixie herself! Life isn't as bad as it may seem, and she enjoys the simplicity of her daily routine, the peace of her recluse world. That is until suddenly she is targeted by the current ruling body of Equestria, Nightmare Moon herself!? Perhaps she spoke too soon. Better run Twilight, destiny is calling!
