It is the time of the invasion of the Frost Giants, and one man must achieve the impossible. Think of a world of witches, of high technology and space travel, of science and superstition. A world on the verge of changing inhabitable planets into green pastures and endless forests, a world so short of energy resources that all fuels are grown or captured from the sun. You say there is no such world? Or that it is only our world, dressed up for a storyteller's pleasure? Set aside your doubts... this world was as real as any you will know... and learn about the timediver's dawn.
