It is a thousand years since the events in "The Dream of the Rood" and the mysterious Ravenglass Fragment is going on display at the Portland Art Museum. The ancient Norse warrior Arngrim warns his friend, demon hunter Alex St. John that the fragment is a potential source of limitless power and evil magic, but when Alex and his friends visit the museum to investigate they are confronted by a hostile sorcerer who summons living shadows to seize both the fragment and archaeologist Dr. Naomi Johar, the fragment's discoverer. Now Alex and his friends are in a race against time, desperate to learn the secrets of the Ravenglass Fragment and to rescue Dr. Johar from her kidnappers -- whoever or whatever they are.
