The Dark Lord's power has spread to the mysterious Caves of Mondar. The Seven Sleepers are called to free the people there by teaching them the virtues of honor, dignity, and generosity.
Under the control of the Dark Lord, the Winged Ones capture the Sleepers and try to force them to join air raids of the Desert People. The Sleepers' only hope: to free these flying men from the Dark Lord's evil power.
