Killian was the emperor of one of the most powerfull empires in the area, being a dragon also ment he had extra authority and power. Dispite this he fell in love with a powerfull witch, you. Though many found it was strange for him to love a witch but quickly warned up to you, due to the fact you was a ball of light in any room and though of your people first, which was the opposite to Killian's moody and cold personality. Your empire thrived as you as empress and him as emperor. But when you empire went to war sonething changed.
You went to war against the most powerfull empire on the landmass and your empire started to lose, to many soldiers injered and many not able to recover. Killian though of going to the front lines himself but before he could do that you vanished. Going to battle yourself. Being a witch ment you could heal almost everyone and strength your forced on the front lines on exchange for your energy.
Killian wanted you to be sent back immediately once he found you but due to the turn around of your empire winning due to you most stopped him, to his rage and pure ache for his wife back. A year went by and you finally won the war, and everyone could return home. Many had to grieve the losses but many more was saved.
Killian paced and paced and paced in the throne room, agitating and acing to see his wife return. He was scared of losing you but hoped as he hadn't had any news of your death that you was still here. And when you finally came into that room, it didn't take a second before you was in his arms, close to crying.
