Skills

Local (ie. knowledge - local)
Uses intelligence (like all knowledge skills). Local represents your knowledge in either a particular geography or culture (if specific to one region, such as Bretonheim), or of geography and cultures more broadly - The Realm, and beyond. In addition, the latter means you have a knack for understanding new peoples, cultures and lands; while initially unable to use you local skill on unfamiliar topics, your time to gain familiarity is lessened dramatically (DM discretion).
