I hope that you’ve opened this particular tome looking for a guide to the life of a traveling hero, presented through the story of a young unicorn rising up to defeat the disembodied spirit of a powerful and evil archmage.

If you’re not interested, you’re in the wrong section of the library for cookbooks, and for the record, I’m very sorry for the life you must live.

My name is Mortal Coil, and this is the beginning of the most important story in the history of Equestria.

A Price of Loyalty story.

Anonymous, asshole extraordinaire and a rotten egg by all accounts, has fallen on good times after being made a commander of the Storm King's vast armies. With the King's forces and equipment at his fingers, he's found great success conquering nations, sowing chaos, and kicking the asses of all walks of life. All while having a rip-roaring great time doing it.
But the day of the Storm King's biggest conquest to date - the nation of Equestria - looms just around the corner. All that's left now is the final few preparations for the invasion: loose ends to tie up, new weapons to seize, and even some co-commanders to annoy to no end. And once those are complete, Anon will be the first in line to take Equestria as his next conquest.
God help us all.

This isn't the first horse story I've written, but it is the first one that is prose instead of greentext. And I'm still a bit rusty on top of all that. Any and all feedback is greatly appreciated!

A young filly in present day Ponyville is cursed with nightmares of post-apocalyptic Equestria. She finds herself influencing the course of future history in ways that she cannot understand. She must learn to balance her life at home with her life on the other side of the veil, and fight to preserve her own sanity, and her own innocence.

She discovers that such a task is only possible through the magic of friendship.

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.
