Moon

Moon was once the city that today is Moonglow. In old Sosaria, Moon already was a city full of mages, however they were of the corrupt and dishonest sort. By the time of Ultima III, Erstam also lived in the city, conducting his experiments for immortality. When Lord British cleansed Moon of all the corrupt mages prior to Ultima IV by chasing them out of town, Erstam and the others decided to go to Serpent Isle, where no one could control them.

Moon was re-named Moonglow and the city became what we know today, the city of Honesty.
