Definitive Edition[]

Dawn of the Dukes[]


As communities grew they had more to defend and more resources with which to defend. The town watch grew into a town patrol usually provided by the local lord as part of his responsibility for the community’s safety. Town patrols ranged far from the community to crossing points or passes where enemies might appear. Longer ranged patrols meant earlier warnings and more time for preparation against attack.
