It's a wonderful subject to explore, though I think there's quite a bit of space in the language for artistic interpretations over time? Does it matter if the heraldry looks different from previous versions or is it really just about the broader images and symbols? I would definitely like to incorporate the use of some shields on a map at some point... or perhaps a form of family crest badges, somehow... or maybe I'll just enjoy researching the finer points of the subject and get lost in the books for a while.
