A Profession is a type of Role denoting a PC's capabilities within interaction scenarios. Professions provide WP values, Initiative, Charisma, trainings, and an ability. As with other Roles, it also provides a set of cards that can be selected for building a deck for interaction.
Of the three roles, the Profession is most likely to affect or reflect a PC's social status and primary source of income. The choice of Profession is not required or expected to inform how a PC interacts casually with friends, family, or even strangers, but rather specifically how they approach situations of verbal conflict.
