Ahh - with a 'Roman' town then yes you would get much more planning and organisation of the layout - makes perfect sense. So other than a legend as Ascension mentioned it's looking really good. One thought - do they cremate their dead? Can't see a cemetary anywhere - though that may not be needed. Always like to have a nice clear cemetary on my city maps - where else can the local necromancer source his body parts.

Entirely irrelevant aside - this would be a good arguement for cultures in magical worlds adopting cremation.... no more 'corporeal' undead.
