This story is a sequel to Awakening

This is the long dark night of the soul. More than 10,000 years have passed since Celestia’s reign over Equestria ended and the entire continent sank into the ocean and faded into myth and legend. Although the pony tribes have colonized the stars, the earth ponies have lost their connection to the land, the unicorns no longer think magic even exists, and the pegasus tribe has forgotten how to fly.
Although the principles of magic and friendship and Harmony are under constant assault in this age of war and strife, a pegasus named Thunder Gale has travelled to the ends of the galaxy in search of a long, lost friend of his. His search has led him to a planet where the old ways have not been entirely forgotten and evils left dormant since Celestia’s time stir once again. In order to survive the night, he’ll have to seek out guidance in the last place he ever thought of looking: the wings on his back.
Not a crossover nor an alternate universe, this is the far future and all this has happened before, and will happen again.

When Rainbow Dash agrees to temporarily care for an abandoned foal, she ends up getting more than she bargained for. Under the scrutiny of the public eye, Rainbow Dash has to try and bring up little Taboo right.

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.
