As the daughter of the Chief in her tribe, Ilsa was born into a royal family. Tragedy struck when her father and brothers were killed in a war and their land was conquered, leading Ilsa to flee on a battleship. However, their ship was attacked and Ilsa was thrown into the turbulent waves.
Ilsa woke up in the hands of Sigwald, a notorious Federation warrior known for his greed. He gave Ilsa a difficult choice: either marry him or become his slave. Initially, she thought he was cold-hearted, but Sigwald's actions and words revealed a surprisingly tender side. Over time, the two developed feelings for each other, despite their different backgrounds and ways of life.
