When Geoffrey steals Excaliburn, Flicker replaces it with an imitation. However, when King Allfire can no longer pull the sword from the stone, the Knights believe the King has lost his right to rule. While Allfire shuffles off to find the Lady in the Lake, Princess Flame and Flicker have to steal Excaliburn back and save Camelhot from Geoffrey's subsequent evil plan.

When a flamboyant Italian inventor attempts to bring Camelhot out of the Dark Ages and into the Renaissance, no one is prepared for his outrageous changes....least of all King Allfire, who is about to go on a trip to the moon with the Italian's latest invention: gun powder.
