After teleporting to Asteroid Eros, Alex and his friends become separated during a battle with the Dark Master. A pair of henchmen accompany the Dark Master after escaping from the Well of Lost Souls. They capture and enslave warriors while some, like Alex and his brother, Dillon, are forced to hide underground. The warriors must sharpen their battle skills, using their talents for mental telepathy, extra-terrestrial vision, telekinesis, and levitation. The Dark Master still wishes to swap souls with Dillon. The key to thwarting that scheme may be as easy and as difficult as finding the Dark Master's heart. Alex must protect his brother, keep the warrior-slaves alive, help rescue the world from catastrophe, and ferret out a traitor. A lot depends upon Alex's strength, skills, and courage. Can he harness the most powerful force in the universe to bring the Dark Master to his knees? If Alex fails, is his soul doomed to be as lost as his enemies' and the Dark Master's?
