First of the Savage Skies series.
After running afoul of timberwolves in the Everfree Forest, Fluttershy is saved by a mysterious young colt with a most unusual and disturbing feature. Realizing that he is alone, without anyone else to care for him, Fluttershy realizes that she must try to bring this lonely foal out of the forest and give him a life of love and friendship. The problem is that this colt's...unique qualities have made him more than a few enemies, including some who are closer to home than Fluttershy realizes.

Now with a sequel: The Promise of a New Day.
Now with a TV Tropes page.

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 A Time of Reckoning: Seven Days in Sunny June, Book IV

The conclusion of the Seven Days in Sunny June saga!

She’s defeated an ancient evil and literally saved all of reality. And due to her death and resurrection, Sunset has now become an alicorn - a literal goddess amongst ponykind. But despite all that, she's still living as a human and that means some very human problems.

Now, as the days wind down towards school and her life (thanks to her grandmother) has become far more different than even she expected, how has her life changed and how will the world before her unfold?

If nothing else, it's a new frontier....

TVTropes page.

Unhappy that her future as a member of the monarchy is denied by Celestia, Sunset Shimmer escapes through Starswirl's mirror into another world, planning to take it over to prove once and for all she was fit to rule. What she didn't expect—besides a species change—was to arrive in a world already conquered.
