The Sword of Teneraz

When an evil act is committed leaving the kingdom in the hands of a betrayer... When the rightful heir to the throne has gone missing... All those who are still faithful have gathered together to form a rebel group known as the King's Men. All of their hopes rest on a prophecy: on a sword and its wielder and a girl and her dragon. All of their hopes rest on finding the rightful heir to the throne. But when they find him will he accept the challenge of fighting to save the kingdom and getting back the throne? Or will he himself fall prey to the darkness?
