Badges/Impressas VS Coats of Arms and Devices
Arms were explained in my previous image. They are used by members of the group to say I am in this group. A badge or impressa can not only say I am in this group, but I am ranked highly in this group OR I am in the north section of this group. Each group can run their badges as they desire. The only major difference with the badge and impressa is the complexity. Impressa is usually a far more complex piece of art, and can be an artistic portrayal of a coat of arms itself.
