 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. "Doubtless," said Zotul unexpectedly, for the youngest at a conference was expected to keep his mouth shut and applaud the decisions of his elders, "the Earthmen used all the metal on their planet in building that ship. By and by, the Earthmen came to Lor, flying through the air in strange metal contraptions. The Earthmen were going to do great things for the whole world of Zur. Accurate reporting, much less a newspaper, was unknown on Zur. Finally, the Earthmen took off in their great, shining ship. 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. This, for some unknown reason and much to the disgust of the Lorians, was set up in Thorabia.
