Camp Purpose
The game also links it as Camp Purposes, Purpose, Purposes.
From the game's encyclopedia
Camp Purposes are what passes for law in the free-spirited anarchy of Camps.
They represent the binding force that motivates the Camp to stay together, whether that be scholarly inclination, sellswording skills, or a burning desire to put a rightful ruler back on their throne.
Different Purposes unlock different Camp Upgrades (and in turn unique Officers), lead to different events or event options, and affect which Contracts are spawned.
Camp Purpose also affects the Adventurer's title and the clothing of their Followers.
