When Ben, Kevin, and Gwen investigate an odd string of thefts by the Forever Knights, they learn that Argit is using Andreas (one of the aliens who were captured by Aggregor) to frighten the Forever Knights into making him their leader. Argit’s plans go bad when the Forever Knights eventually revolt (under Sir Dagonet), and throw him into a dungeon with Ben and the others. When they discover that the Knights plan to execute Andreas, they break out and save him. As a last act of spite, Sir Dagonet sets a bomb that will destroy everything within five miles. Andreas sacrifices himself to absorb the force of the explosion. Although Ben and company believe him to be dead, Andreas survives and was recaptured by Aggregor.
