The colour pallet for this one might be changed, I'm not to sure yet.
All guards have the marking under there left eye to show that they are a guard even when its there day off. its like a magical branding, the only way to remove it is to retire, the symbol is a symbol to one of the great city leaders family
^Same goes for he amulet, that amulet gives them access to certain areas of the city that are restricted areas.
chest armor can be used with this attire but most choose not to use it because they don't like it, its not like they are going to war or anything...
