Ned Stark is murdered by a demon at the same time as his two daughters go missing; Robb, suspecting that the same demon that killed his father is responsible for the disappearance of his sisters, takes his half brother Jon with him for vengeance. The two men leave their northern home, and travel across the country, hunting monsters, and searching for the demon that killed their father. Along the way, they meet a very snarky fallen angel named Theon, and, well, what do you think happened.
