Two thousand years after the return of Princess Luna, Equestria's technology and magic has advanced far enough that the once far off dream of faster than light travel is now a reality.

And that reality is the ES Harmony, the pride of its designer, Princess Twilight Sparkle, and Equestria's first FTL capable starship. It is due to make its maiden voyage to travel further than anypony before it.

And yet when they receive a distress call from origins unknown, this ship's maiden voyage will become one the crew will never forget.

This story is a sequel to Stardust

Twilight has finally returned home from the harrowing challenge that Discord set upon her, and the residents of Ponyville and the Elements especially look forward to having their dear friend returned to them.

Twilight, however, has changed. Still suffering from her injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her. Will her frustration at her current state and her friends inability to understand her experiences cost her what she valued most before Discord's bet?

Magic, the most forbidden art. Only nobles are allowed to learn from the great wizards and witches, and only from special schools set up by the state. For commoners, learning the mystic arts is nothing but a dream, a fantasy that many strive for but none achieve.

With one exception: Stalliongrad. The great, northern city boasted more magic schools than any other, and among them, the only one that accepts low born ponies. It's a dangerous trek to get there, and even more dangerous to simply stay in the frozen city.

Twilight Sparkle, however, will not be stopped. Destined to become the archmage, destined to sit at Princess Luna's side, she will not be stopped.

After all, Archmage Twilight Sparkle has a nice ring to it.

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.

Twilight Sparkle can't seem to catch a break. Two polar opposites from completely different worlds. Yet amidst her dominant rule, Princess Nightmare Moon feels she's missing something. A certain day from her memory has been wiped... and none of her common materialistic desires can sate her quench for answers. That is until she encounters a certain young unicorn mare, who she can't seem to get off her mind.

Twilight Sparkle's dull and downtrodden life is about to get much more interesting.

[Inspired by S5 - Nightmare Moon AU: Thank you for your support!]

Certain alicorns have no regard for the rules of space and time. An astral sub-dimension becomes a potent weapon in what appears to be a divine prank war. Shining Armor hits the sauce.

Written for this contest thinger.

Herself.

All while dealing with her own shattering reality.

Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”
