The Earth is under attack.
The demon lord B'harne, servant of the malevolent alien High Magus of Lyra, has commenced his assault on the human race. Under the benevolent guise of the children's television host Barney the Dinosaur, B'harne seeks to destroy the minds of children and adults and bind them to his tyrranical will. Once he has made mindless slaves of humanity, B'harne will rule the Earth with an iron talon.
