The raiding party is an annual event. In the last days of autumn, before the snows close the pass to the north, the orc tribes send their young adults, usually under the supervision of a few more experienced raiders. There will be at least ten and possibly as many as twenty raiders. They will travel through the pass, raid the nearby farms and carry off whatever they can back through the pass. They try to time it so the pass will close behind them. That way, we can't chase them until the spring when they'll be long gone. It is late autumn now, so we expect their arrival any day now.
