question:  Who changed the least throughout the story?
context: Personally, he was in favor of the coming of the Earthmen to the world of Zur. "It is a damned imposition," agreed Morvan, ignoring his father's philosophical attitude. By this, he seemed to imply that the Thorabians would rob the Earthmen, which the Lorians would not. Only the speaker's youth could account for it. "When your opinion is wanted, we will ask you for it. Speeches were made through interpreters, who had much too quickly learned the tongue of the aliens; hence these left much to be desired in the way of clarity, though their sincerity was evident. There was also some talk going around about agreements made between the Earthmen and officials of the Lorian government, but you heard one thing one day and another the next. Accurate reporting, much less a newspaper, was unknown on Zur. Finally, the Earthmen took off in their great, shining ship. Obviously, none had succeeded in chiseling them out of it, if, indeed, any had tried. 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. In the meantime, however, more things than pots came from Earth. This, for some unknown reason and much to the disgust of the Lorians, was set up in Thorabia. The remainder of the brothers Masur, on the other hand, preferred to remain in ignorance. 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. They destroyed it, which proved how valueless it really was. In their dozenth conference since that first and fateful one, the brothers Masur decided upon drastic steps. For one, old Kalrab had passed on to his immortal rest, but this made no real difference. What they did mention was the crude oil and natural gas they discovered in the underlayers of the planet's crust.
