Warden

undefined:

A Warden is a special kind of Protector that keeps the system safe from malicitors and persecutors by keeping them 'jailed' within a section of headspace or otherwise dormant/incapacitated. The term derives from the name of the chief officer in charge of a prison in the United States, and can be called a superintendent, governor, or director in other parts of the world.

Not all Wardens are benign; some are corrupt or active persecutors themselves who jail other headmates in a misguided attempt at keeping 'order' in the system.
