By tradition, I mean the rituals, gestures, etc. practiced by characters in their respective cultures. In that sense, these are worldbuilding thoughts.
Traditions are an important part of any culture, even today. Breaking them, depending on the circumstances, can change relationships or the way one is viewed within their community. Works in fantasy often have longstanding traditions within the lore, some familiar to the audience, some maybe not.
Either way, it’s worth thinking about.
