It is interesting to note that no "city of Moron" is ever mentioned as part of the land of Moron or within the Jaredite "land of their first inheritance." (Ether 7:5, 16-17) This lack of a "city of Moron" certainly can't be due to inadequate population or cultural abilities because the land of Moron is mentioned from the beginning of the Jaredite civilization unto the end (Ether 14:11).
One might ask, Why then is no city of Moron mentioned? Could it be that Ether (or Moroni) did not want the reader to feel that the land of Moron was always ruled from the city of Moron? In other words, was it possible that as the land of Moron grew through the years, that various kings ruled it from various locations? If so, then when Ether (or Moroni) mentioned anything concerning the "throne," he might have felt he was confusing the issue of location if he originally had the throne established in the city of Moron.
