Swordsman of Lost Terra

 It was thought to have been a planetary disaster whose roots could be traced all the way into outer space. Earth had gone through a cataclysmic change and one side of the planet, like its moon, was now perpetually facing the sun. The great civilizations of Earth had nearly been destroyed, and the few survivors who remained had fallen back to primitive ways. However, the men of Killorn held a weapon that none others had…the pipe of the Gods. This fantastic instrument spelled death for any enemy who stood against it. Master sci-fi author Poul Anderson spins a science fantasy tale of Earth in the far future. It is the story of the Men of Killorn, and how their leader, Red Bram, led them against the glowing-eyed hordes of the Genasthi, who had invaded from the lands of perpetual darkness; and how Kery, son of Rhiach, played the pipe of the gods once more.
