True but they are fed by the region for free, only have to go one region away, it only takes them an hour for there missions, and travel taxes are not done to them. I pay for taxes to go to some regions/or realms (not sure) which was done during my scouting, I pay 2 silver a day for food, travel quite the distance taking all of my time for 2 days in my task because of there being several regions to visit within the other realm. So I think more than 10 silver is due.
