The Grand Duchy of Hessenguard lost its master. The two kingdoms, that were vying with one another for the dukedom, agreed to send their respective candidates from the royal family to marry and make their successor the heir of the duchy. And so, Erna and Kalion arrive at Hessenguard to wed. But, their initial impression of each other was extremely terrible. Thus a marriage started just like that from the beginning with a horrible impression of one another. They showed their teeth to each other for more than a decade, but lived together steadfastly for the sake of the Grand duchy. Later, one day, a letter was sent for them. ‘You will have a successor within one year.’ After 10 years of marriage without any children, both nations raised the issue. They said that if they don’t have children within a year, they’ll bring them back home. Is it possible?
