"Evil is the magic that floats silently t the land of Nog and the strange, intricate device that Olaf the Lofty and Graculus have devised must be pressed into service sooner than expected. How it serves the Nogs and how it descends at last on the dry Land of Silver Sand to bring justice and happiness to that sad place, and how the dragon himself fights in black smoke in the sky, are told in this, the third tale in the Saga of Noggin the Nog.
