The School of Friendship has new Teacher Assistants!

The Cutie Mark Crusaders have been welcomed into staff on a probationary basis in order to assist their sisters (and Rainbow Dash) with their classes. Today just happens to be the day for the School Trip to Canterlot Castle for a certain group.

When things go wrong and our characters are flung into the Void and come out in one of many worlds at war, what kind of challenges will they have to face? And if they survive... what will they bring back with them to Equestria?

Many thanks to Petrichord and GapJaxie for their feedback and assistance.

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.

[Warning Spoilers] Twilight's Nightmare Art

Nightmare Moon has returned. Princess Celestia lied and betrayed her star pupil, Twilight Sparkle, leaving her woefully unprepared to fight the Queen of the Night.

But when she fails, rather than disposing of her and the ponies that tried to help her, Nightmare Moon sees an opportunity and a necessity. Having been locked away for one thousand years, who better to help her solidify her rule and keep Equestria from collapsing, all while rubbing it in her sister's face, than her own betrayed pupil?

Sombra's takeover took everyone in the Crystal Empire by surprise. No one saw it coming, none were prepared for it, and almost no one got away. Almost.

A few hooffuls of daring souls managed to break out of the city and flee southwards, towards Equestria. Some ran to beg the Princesses for aid, others - just to save themselves and their families from the mad tyrant.

But as the refugees are about to learn, it's the dead of winter outside the Empire's shield, and the crystal ponies are far too used to their warm life in the city. One filly that gets separated from her parents while trying to get away learns that fact all too painfully...
