After a mirror portal field trip being conducted by Luna goes terribly wrong, Ocellus finds herself trapped in a strange palace far from home. That palace, once abandoned, is now infested with a hive of love-starved changelings intent on using her only way home as a means to invade her world.

Otherwise, Ocellus appears to be alone.

At first.

The story is inspired by, and a homage to, my favorite game of the last decade. However, this story is neither a crossover nor AU. This story is set after "The End of the End" (but before "The Last Problem"), and is purely a My Little Pony story. Warning: rudeness and intolerance are not allowed in the comments, but spoilers are. Exercise discretion. Remain polite and on-topic. And please enjoy the story!

War comes to Equestria: with despair, with starvation, with suffering and with sacrifice. And the ponies must learn how to keep true to their values while surviving not just the rigors of battle, but the desolation of total war.

A letter from Celestia interrupts one of Pinkie's parties with disturbing news. Now friendships will be pushed to the limit as Twilight struggles to uncover which of her friends is not who, or even what, she appears to be.

(While not a romance, this does contain a shipped pair)

This story is a sequel to Musicians and Dreamers

Octavia Philharmonica has betrayed her friends and allied with the corrupt nobles of Luna's Court, but her usefulness is at an end. After a discovered attempt to redeem herself and save her friends from the politicians, she finds herself compelled to play the infamous Symphony for Moon and Sun -- a piece from which no musician's career has ever escaped intact. Princess Luna hates the piece and shuns anypony who dares play it, and no venue will host a pony shunned by the princess of Equestria. In her desperate straits, her only hope is the aid of her former student Lyra Heartstrings... but not only is Lyra still feeling the effects of Octavia's betrayal, but Octavia isn't even sure that she deserves the help. Can Lyra get through to her former teacher and help her survive the most important performance of her career? Or will both of them find their careers crashing to a premature end? Lunaverse story.

Celestia leaves to deal with a foreign crisis, giving her sister a chance to rule alone and become more attached to the modern world. She calls on Twilight Sparkle to advise Luna, hoping her student will be able to draw Luna out of her shell. With two major threats to Equestria already defeated in the past year, it seems like the perfect time to let Luna gain some confidence and experience in the modern world. After all, what are the chances of a third disaster occurring?

Now comes with complimentary tropes.
