In reference to some of your questions: the Templars were the grand knights of Silith before the Council took over. They wore enchanted golden armor and used light magic, being able to cast light healing spells and also blasting enemies with holy fire from a distance (think paladin esq.). You mentioned "the other mages," but because your characters are commoners use of magic for any sort of fighting is grounds for execution. Usually the only people that know if you have affinity or not is your closest friends and family. Making a retired paladin would be interesting, as he would have all sorts of lore (I can make up some stuff, or you can build the world as you see fit) from before the council. If you have any more questions don't hesitate to ask.
