“ When was the last time a character caught a cold or flu? Real people get them every now and again even with solid heating and dry interiors. Your characters are out in the cold and wet, and even inside is not always dry and warm. Imagine having to stop your dungeon crawl, sitting in a tight defensive position, while you all are feverish.”
“ A religious group has a vow of poverty. They have nothing except what is donated to them. Once a day the group walks through the town holding small baskets for offerings. Main purpose is to recieve their food for the day. Most families believe it is good luck to give the group small foods that they can spare. The group is very grateful for the donations and all bow in unison to each that gives a donation much to the amusement of many kids that enjoy giving the donation.”
“ The player characters, experienced and somewhat well known, hear rumors and travelers' tales about a distant area being overrun by dragons (or other terrifying monstrosities). The locals have sent them a message, begging for heroic aid.
When they investigate, they discover that nothing of the sort is going on. It turns out that a group of thieves wanted them out of the way so that they could rob them (or someone who would normally receive their protection).”
