Ylva and Solvej are sisters who are about to go on a mission. 

There are things in this world that people don’t know or understand. We live in a world where people see what they want to see, believe what they want to believe, and understand only what they want to understand. My family has the sacred duty to protect those people from everything in between. We are the children of the Norse Gods, a group called the Warriors of Freya. We are all that stands between the world that people think they know and the world we actually live in.
