System Guard

undefined:

A system guard is a headmate who fronts to protect a system from being revealed to those outside of the system. System guards may do this in order to protect the system from those they perceive to be unsafe, to keep the system covert, or to keep other headmates from revealing themselves.

Regardless of whether the system is truly in danger, this headmate will take whatever action they feel is necessary, including but not limited to:
 * causing heightened dissociation
 * completely taking over front
 * doing things other system members may deem harmful (e.g. lashing out at those outside the system in order to end the situation that brought them out)

System guards could be considered a form of protector or gatekeeper; they are differentiated primarily by their ultimate goal being protection of the system’s covertness.
