This measures a character’s connections, reputation, and resources. High Influence can allow a character to quickly summon the aid of local military forces to their side, or arrange for fast transit to another star system. Unlike the other characteristics, Influence changes only as a character performs actions: it would decrease should they fail a mission in a highly visible manner, for example, or increase after they successfully rescue a kidnapped planetary governor.
