As he spoke, my father often referred to the planet of Gor as the Counter-Earth, taking the name from the writings of the Pythagoreans who had first speculated on the existence of such a body. Oddly enough, one of the expressions in the tongue of Gor for our sun was Lar-Torvis, which means The Central Fire, another Pythagorean expression, except that it had not been, as I understand it, originally used by the Pythagoreans to refer to the sun but to another body. The more common expression for the sun was Tor-tu-Gor, which means Light Upon the Home Stone. There was a sect among the people that worshiped the sun, I later learned, but it was insignificant both in numbers and power when compared with the worship of the Priest-Kings who, whatever they were, were accorded the honors of divinity. Theirs, it seems, was the honor of being enshrined as the most ancient gods of Gor, and in time of danger a prayer to the Priest-Kings might escape the lips of even the bravest of men.
