From publisher blurb:
Grand marshals are gun-toting law enforcement officials. The skill with which they wield their firearms makes them a force to be reckoned with, and their badges are enough to open virtually any door and to hold any citizen to account in the lands from which they hail.
Prestige Class: Shieldmarshal
Role: The grand marshal investigates crimes and unrest and generally has to apprehend the guilty and enforce the law in person, often in cohorts with a posse. In a dedicated team the grand marshal is the face, investigator, and artillery of the group.
