(Regency Au)
The Storm King's becoming more tyrannical and more adamant on taking over Equestria. So Princess Twilight Sparkle must make the biggest sacrifice of her life, become his fiancé so the other princesses can have more time to think of a plan to take him down.

But hey, maybe it's not all bad! Her body guard, once the captain of the Storm King's army and his right hand mare, is pretty cute.

(WARNING: Prologue is kinda, depressing, I promise it'll lighten up a bit tho!!)
