Tanya Degurechaff gets tossed into Equestria and transformed into a Changeling Queen. It's a nice retirement from modern warfare as an aerial mage. Then Queen Chrysalis attacks and forces her out of retirement. Historians refer to this as 'a bit of an oopsie.'

Equestria has witnessed centuries of rapid technological advancement during Twilight's rule. Innovations in the production and integration of magic has led to countless improvements in the quality and efficiency of life in Equestria, and enabling ponies to finally touch the stars and new worlds. However, with the rise of more and more energy-heavy processes and a stagnation in development regarding the extraction of energy, Twilight turns to the biggest and final step in energy extraction: a dyson sphere: a massive device that would surround the sun and allow virtually all the energy released through nuclear fusion to be harnessed by Equestria.

Two former princesses have some concerns.

Written as an entry for the Science Fiction Contest III.

Ever since the return of Nightmare Moon, Princess Celestia has noticed that her student and her friends have been getting into a lot of trouble, so, naturally, she worries that they may end up getting hurt while they're unable to protect themselves. Thus, she assigns a very special guard to keep watch over them, without them knowing, of course.

Ever since he'd met the Princess, he'd been serving her faithfully, how could he not? But when she tells him to head down to Ponyville to keep her student and her friends safe, he can't help but wonder if this is the best use of his time.

Unfortunately for Emerald Skies, a job is a job, and he'd be loathe to ignore an order from his Princess.

Twilight did her duty. She saved everypony she could, except herself. Now trapped by an evil cult, in more pain than she has even been in before, and dying on a sacrificial altar, she calls for help. The Nightmare answers.

Will Twilight become the next evil to threaten the world or will the Nightmare simply be glad to have some freedom? One thing is for certain, Twilight's life will never be the same again.

In this new land they discover plenty of opportunities to start a new life, ranging from being a student of magic to being an adventurer of ancient ruins, or dealing with bandits to being a grand thief, and everything in between.

There is a Russian translation about this story, Celestia's story and Luna's story on FicBook, PonyFiction and Tabun.

To ascend the throne, an Alicorn must take it by force. Twilight has been raised by her Aunt, a horrific dictator, vowing one day to steal the throne from her. Twilight wants revenge for events that happened 1500 years ago. Her wings, her power; all of it was taken from her along with something she thought lost forever.

Upon moving to Ponyville, Twilight pretends to play by her Aunt's rules while secretly plotting her downfall. She meets a few mares that she 'convinces' to help with her devious plans. Celestia is always watching, and to make matters worse, Luna is returning from the moon soon.

The question is: Of the moon, the sun, and the void...Who is the real monster?

Spike had never thought he would meet his birth parents, he had been with Twilight for quite sometime now and he was starting to lose hope that he'd ever meet them. But when he goes to the Dragon Lands to see the Migration, he not only meets a kind dragon who helps him through the place, but he also helps find someone he never thought would get to meet..

This story is a sequel to Change
