Back when I introduced the profession of armin in Daughter of Mystery, it was to some extent a means of creating a social context in which Barbara would make sense. It also became an aspect of developing Alpennian society as its own thing. Other societies had a dueling culture. Other societies had systems for guarding the virtue of young unmarried women. Other societies had personal bodyguards. But somehow in Alpennian culture those elements had come together in a recognized profession that acted as proxies for their employers in the public performance of "honor culture."
