Magic

Since this is high fantasy, everybody uses magic--no, seriously. Everybody. From shooing the flies out of a room for a dinner party to playing some mood music, every commoner knows at least a few choice rituals to get them by from day to day. Some people are better at it, granted, but almost anybody can use it.
