In the 14th century, Templar knight Jean de St. Clair was tasked with piloting the orders treasure-laden fleets off the coast of France. To this end, he used the Jacobs Staff-a nautical instrument supposedly developed in his own time. But retired Army Ranger Lt. Col. John Holliday possesses a Staff he found in the hands of a 4,000 year-old Egyptian mummy. Holliday suspects that St. Clair may hold the key to unlocking the mystery of the ruthless, enigmatic Templars.
