Hmm. Well I may have to rethink a bit of my character's history, but that'll be pretty easy.
I haven't actually done much research on historical city-states but it just seemed a bit odd that all the cities are identical in the way of education (without some kind of inter-city government deciding and enforcing these standards).
I wonder if they have a standard set of spellings or if due to the isolation of certain cities, there are words that are spelt differently in Common depending on the location.
