Outside, Lola and Twigleg found Gravelbeard. In the struggle that follows, the Dwarf's hat (which functions as an altitude compensator), is taken by Twigleg. Promptly Gravelbeard is struck with mountain sickness, allowing himself to be taken a prisoner. Nettlebrand, who now knows their location, is coming. No one knows how they could ever stop him since he is twenty times as strong as one dragon as well as immune to other dragons' firepower. In disgust, Sorrel spits on the golden scale which the Professor gave to Ben. Inspired by his success with the Ravens, Firedrake breathes fire on it and reduces it to gold paint. Twigleg comes up with a plan. He pretends to be still loyal to Nettelbrand and frees Gravelbeard then sent him back to Nettlebrand. The Golden One, elated by upcoming success, orders the Dwarf to polish his armor. Unfortunately for Nettlebrand, the armor polish has been replaced with Brownie spits. When Nettlebrand enters the cave, he was at once dive-bombed by Firedrake, Maia, and Lola in her plane. At last, the Dragons came together and set Nettlebrand afire. The Brownie spits reacted at once, dissolving Nettlebrand's armor and destroying him. Nettlebrand melts to reveal nothing but a toad underneath. As the company stare in wonder at this transformation, Gravelbeard enters. He has seen the marvelous gemstones and rock formations in the cave, and wishes to enhance them with his own skill, revealing that doing so will bring the petrified dragons back to life. Within a few days, all the silver dragons are awakened again. Firedrake and Maia went flying with Sorrel and Burr-Burr-Chan to bring the other members of their species back home. Ben and Twigleg went to live with Professor Greenbloom and his family. Two months later, news reached the humans that Firedrake has convinced the silver dragons to come with him to the Rim of Heaven. Eager to see their friends again, Ben and Guinevere occupy their time with other investigations of "imaginary" creatures until they can visit the silver dragons again.
