Matters become further complicated with the arrival of Princess Ardala on the Draconia, who has brought along Wilma and Dr. Elias Huer during a temporary truce between her world and Earth. Buck enlists the aid of both Earth and Draconian forces to save Pendar from the attack of a huge Zaad battlecruiser.
Buck journeys through a space warp to another universe. There he discovers the planet Pendar, a peaceful world now threatened with the extinction by the sinister war witch, Zarina (Newmar). The Pendarans enlist the help of both Buck and Princess Ardala. The Draconians have followed Buck through the warp with Wilma and Dr. Huer aboard the Draconia. An unsteady alliance between the terrans and Draconians is formed as Buck prepares to lead a combined fleet of Starfighters and Marauders against the giant Zaad battlecruiser.
