 The Lone Power, suspecting that a new threat is rising to its dark abilities, creates a surge of Dark Matter, called "the Pullulus", to eclipse the universe.Because of the way that the Pullulus affects the universe's structure, the Senior Wizards lose their wizardry and only wizards before adulthood are still able to fight.Ponch uses his tracking abilities to lead Nita, Kit, Ronan, and the wizardly tourists from Wizard's Holiday Filif and Sker'ret across the galaxy to try to find and activate an instrumentality that they are told is the only way to stop the Lone Power.
