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.

After years of shame and ridicule, archaeologist and explorer Lyra Heartstrings stumbles across a discovery that validates all her theories and ideas in one fell swoop. Along with her best friend, Bon Bon, and her old classmate Cadance, they find themselves faced with a mystery and marvel that may change everything.

Following the next greatest lead found in the database of an ancient race, another international team is formed. Led by Doctors Carter and Jackson, they strike out to explore another network of Stargates discovered in a galaxy on the edge of the local cluster. In the process, their findings will cause them to question much of what they thought they knew.

The adventures continue and unlikely allies will face dangers new and old as the Legacy of the Ancients continue to unravel in the latest chapter of the universe.

This story is a sequel to A Thousand Voices

"Together, we can build a future greater than any one of us could imagine. A future paid for by the sacrifices of those who fought and died alongside us. A future that many will never see..."

For seven months, Equis was left in peace, and for seven months Twilight Sparkle has waited for the return of Legion. Just as she is ready to give up hope, the galaxy decides it is not finished with Equis. Unfortunately, it does not send someone as patient as the geth...

For the alien civilizations of the galaxy, they fight for their lives against the greatest threat ever known. And when victory is finally achieved, the crew of the Normandy find that their mission is not over just yet.

The village had been perfect, free from the inequality and misery rampant throughout the rest of Equestria. Then Twilight Sparkle and her so-called friends arrived and ruined everything.

But all hope is not lost. Starlight Glimmer has a plan to restore her lost utopia on a much vaster scale.

After all, it's not like that purple princess was friends with anything worse.

Story contains spoilers for the Season 5 premiere, nonspecific allusions to torture, and nuts. Story does not contain Nikita Khruschev or shoes.

Death is a natural part of life. Exploding out of your anus, however, is not.

Dedicated to TGM, Rainedash, and Kamikakushi, who gave their lives in the prereading of this work. May they rest in peace.

This story is a sequel to A Mad Glimmer

The plan had been perfect, taking everything from Twilight Sparkle and trapping her in a no-win situation. Then Twilight showed Starlight the alleged consequences of her actions.

But there's a bit more to the story. Starlight Glimmer has paid a heavy price, but there's one more debt to call in.

After all, Discord doesn't make idle threats.

Story contains spoilers for the Season 5 finale, potentially disturbing imagery, and nuts. Story still does not contain Nikita Khrushchev or shoes.

Celestia and Scootaloo are homeless in a Ponyville alleyway together. They like to talk about things.

These are the things they talk about.

Note: The crayon scribbles of a plot is done, but the ride never ends story still updates.

Spartan Adam-D014 was a lone wolf assigned to the UNSC Lightning. What was supposed to be a routine mission ended up with the frigate being ejected from slipspace unexpectedly, and with Adam landing on a strange planet inhabited by colorful, friendly equines. But something's not quite right... Adam's turning up in Equestria was more than mere coincidence, and Adam is determined to find out just what is going on.

Enjoy!

Following the destruction of the Collector Base, the crew of the Normandy-SR2 go their separate ways. One squadmate, an AI 'Geth' named Legion, is sent by the Geth Consensus to investigate the possibility of a Quarian attack. However, when Legion is discovered and forced to make an emergency jump through the Mass Relay, it finds itself in the most unlikely of places... Equestria.

At the same time, the ponies of Equestria are dealing with their own problems. A mysterious disease threatens to topple pony civilization, while tensions along the border are growing and could escalate into full blown war.

Join Legion in its journey in Equestria to both return to the Geth before the arrival of the Reapers, and to help the peaceful ponies who inhabit the world.

Notice: As of 9/12/2016, this fic has received comprehensive updates to grammar/spelling/sentence structure, with a few minor plot alterations. Enjoy!
