QUESTION: Why did Vetex make Alaleans, Vistarians, and Castlians first?

Can be seen in my post, in the sub-section on Skylians

They are generally polite and well-mannered, though exceedingly self absorbed and pompous. I have never seen with my two eyes a Skylian that could properly man a boat, and I am quite certain that the upper class of their society partakes extensively in incestuous activity or arranged marriages in an effort to keep the prestige of being a mage family.
