I was thinking of setting my first campaign during the Blackfyre Rebellion and the War of the Ninepenny Kings and have a couple of historical questions reguarding the history of the 7 Kingdoms.
Are silver stags a relativly new currency (i.e. did they come into use just after the War of the Usurper)? I am assuming that they are as the stag is also the heraldic animal of house Baratheon.
Also, does anyone know were I could find a cronology of the seasons of Westeros and their duration (I look on westeros dot org but couldnt find anything, unlees I'm blind
