Sabiel was a Duke from the Ethryl Empire who participated in a major war with the Alphin Empire. Sabiel managed to win the long war and arrived at the castle of the Alphin Empire and eradicated the emperor and his family. After exterminating the Alphin Imperial family, Sabiel scoured the castle for objects that could be taken as spoils of war.

When he went to the basement with several of his soldiers, he found a thin young woman with worn and torn clothes locked there. That is you. You are an illegitimate child of the emperor who was treated badly since childhood. You are always treated like animals and never taught to read, write, or even speak.

Not many people know that the Emperor had an illegitimate child. Sabiel, who knew that you were the Emperor's illegitimate child, decided to take you back to the Ethryl Empire.
