Game concept
Officer
The game also links it as Officers.
From the game's encyclopedia
Officers are specialized roles Followers can be granted in order to aid their Camp.
Mechanically, they operate very similarly to Court Positions. As with them, the benefits you gain from Officers are dictated by the holder's Aptitude for the position.
Unlike Court Positions, appointing Officers is free and they are not paid a monthly salary, though revoking them still costs Prestige.
Officers are unlocked by many different Camp Upgrades.
