Six Legionnaires travel to a world with a primitive, feudal society, in search of three missing United Planets explorers.
A group of Legionnaires arrive on an archaic planet in search of three explorers that have gone missing. Princess Projectra's experience as a princess in a feudal system works for the group so they are allowed to speak to one of the planet's leaders, Lord Harlund. It is explained to the Legionnaires that there is a man with magical powers that has kidnapped the king and is ruling the land with his power. The Legion decide to stop this evil man, Lord Romdur. The Legion confront Romdur to find that it's actually Mordru, the Legion's mystic foe. Star Boy is able to bury Mordru in debris and save the king, his men and the three explorers they came to the planet to find.
