Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

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.

This story is a sequel to I Don't Want to Grow Up

Celestia was a filly living on an isolated farm with her sister and harboring dreams of greatness. Chrysalis was a black goo poured out from a screaming wound in the walls of reality, with a weak grasp on the appropriate amount of fangs one should have. Friendship was inevitable.

Pre-reading and suggestions by bloons3

In the beginning, The Great Weaver brought together the world, from the mountains to the forests. Stitching it together, the Great Tapestry connects all living and nonliving things.

The Changelings found themselves especially connected to this Tapestry. Legend says that the first Changelings fell through the world as it was woven together, only to be caught on the First Weave beneath it all.

But what happens when something else is caught in the Weave?

Prince Phasmatodea, son of Queen Chrysalis, remembers what it was like before he hatched. He remembers being a human. He remembers dying. And he fully intends on avoiding another death.

But being gifted a new life does not matter when one failure, one false step, will lead to your untimely demise in the Changeling hive, for Prince Phasma must survive his toughest adversary from the start: Mother Dearest.
