Earth, the year is 2065. After a wave monsters from space invaded in what has been dubbed the "First Incursion", the world created a organization to stop these vile creatures called S. M. I. L. E. (Space Monster Interception League of Earth). To train the next generation of defenders, SMILE Academy was created, and it is here that they will be imparted with the knowledge and skill to fend off any hostile threat. However, an evil has set its sights on Earth, and wishes to initiate a Second Incursion.

But all hope is not lost, for one student, Sunset Shimmer, has the power to repel this extraterrestrial threat. Using her otherworldly device, the StaRaizer, Sunset will set out on her journey as Ultrawoman Aster! Now, if only she could remember how and why she has this power...

A story of discovery, of battle, friendship, and possibly love? It's time for the universe's newest Ultra Warrior to take the stage!

This story is a sequel to Celestia

Villains rarely appear out of thin air. They start as most creatures do, but fall victim to fate, choice, manipulation... or love. Princess Luna's descent into the Nightmare is something that has been long forgotten by modern ponies, but Luna will always remember.

(Sequel to Celestia, and a part of the past that she would rather keep hidden. Reading Celestia is strongly recommended!)

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.

Featured 5/27/2020

Seven hundred years ago, Princess Celestia lost her daughter to the human world. She went mad, deciding that humanity must pay. She crossed the dimensional veil and thus the Solar Tyrant began her war. She did the unthinkable, bringing Equestria to Earth, destroying one world in the process and nearly destroying another.

However, neither Princess Luna, the Bearers or their allies could stand for this and so they waged war against the Tyrant, quickly moving to aid humanity. Technology met magic, and somehow, humanity survived.

Now Sunset Shimmer has reincarnated...into a world full of chaos and strife. And the only way to end it is to kill the one responsible - her mother.

No one ever said a hunter's job was ever easy.

EqG/The Conversion Bureau/Destiny crossover.
