 What was the real reason for the Earthmen to come to Zur?
"It is an outrage," said Koltan of the House of Masur, "that the Earthmen land among the Thorabians!" Personally, he was in favor of the coming of the Earthmen to the world of Zur. By this, he seemed to imply that the Thorabians would rob the Earthmen, which the Lorians would not. The Earthmen were going to do great things for the whole world of Zur. One day, a fleet of ships arrived and after they had landed all over the planet, Zur was practically acrawl with Earthmen. Immediately, the Earthmen established what they called "corporations"—Zurian trading companies under terrestrial control. In spite of the fact that a terrestrial ship had landed at every Zurian city of major and minor importance, and all in a single day, it took some time for the news to spread. Within five years of the first landing of the Earthmen, every major city on the globe had a printing press, a daily newspaper, and enjoyed the instantaneous transmission of news via telegraph. "As I have always said from the beginning," chortled Director Koltan, "this coming of the Earthmen had been a great thing for us, and especially for the House of Masur." For another, the Earthmen had procured legal authority to prospect the planet for metals, of which they found a good deal, but they told no one on Zur of this. Crews of Zurians, working under supervision of the Earthmen, laid pipelines from the gas and oil regions to every major and minor city on Zur.
