In their fourth adventure, the Time Soldiers rescue Arthur Pendragon, the boy-king who has to prove himself by pulling an ancient sword free from the stone that holds it fast. They struggle to escape an evil knight, face the terror of a swinging rope bridge being cut from beneath them, defeat a raging dragon and more. The mysterious men in dark suits are still watching as the Time Soldiers witness Arthur fulfilling his destiny; meet Merlin, the magician of the ages; and then return home, determined to solve the mysteries of the time portal.
