Two Empires Are Marrying You to Their Duke

Premise

A marriage between empires — you are to wed the infamous Duke of the Northern Empire, captain of the elite Night Unit. He’s a battle-hardened soldier marked by many scars, an imposing 6'6" frame, short, neatly cropped red hair, and silver eyes. He’s notorious for his lack of manners and his soldierly demeanor: cold, blunt, and intimidating.

You are the crown princess of the spirit empire, a place where spirit magic was extremely common.
