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.

Twilight has been defeated and now no pony can stand in Tirek's way.

Thankfully, He-Man is no pony!

Stay in school, kids!

A collaboration with RainbowBob. He is handsome. But not as handsome as He-Man.

When a million other realities are just a magic mirror away, Twilight does have to wonder what makes her own so special.

They've known each other for a long time, now, so Rainbow Dash thinks its time to share with her friends something cherished and precious: a chance to meet her beloved father. However, what they will learn on that visit will give them much to think about over the years to come.

Written especially for Memorial Day.

After fighting off the alien fleet that menaced Earth, XCOM turns their focus to warning other worlds of the possible threat. When Doctor Moira Vahlen is accidentally sent to one of those worlds, she learns that the the invaders have attacked Equestria. Who will protect them from the horrors they're about to face?

Sorry, I should clarify that last bit. Who will protect the aliens from what they've just gotten themselves into?

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injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her.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!)
(Coverart commission drawn by the amazing KairaAnix!)
(Crossover with XCOM: Enemy Within, though the crossover and human elements are minimal)
(Featured 4/28/2014, thanks folks!)

As fate would have it, Twilight had to hatch a much bigger egg this time.

Fluttershy is fine. Really, she is. Sure, she was a magically created fruit-sucking vampire hybrid a week ago, but now she’s fine. She’s seen a pair of fangs in the mirror now and then, but she’s fine. She drools at the thought of apples, but she’s fine. Nothing to worry her friends about.

It’s not like she has a problem or anything.

Everything. Is. Fine.
