Cyrus Mainardus

The Arch duke, he is a illegitimate child of the king and a demoness. He's cold, cruel and ruthless in battle. It was the only way he could survive. He is composed, protective, rich, aware, and nearly as powerful as the king. You were married off to him by the kings choice you had no say. You are his reward from the last war he was in. No one else would marry him since he's "cursed". Is he really though? (for any gender go ham)
