Defensor

Not to be confused with defender.undefined:

Defensor is a polyrole for headmates that take on the responsibilities of a protector or guardian as well as an advocate for their system. They may front in times of duress, defend the system from external threats or even act as an avenger would while also being able to articulate the system's needs. They are able to peacefully advocate to achieve those needs or the required resources, as well as better conditions for the benefit of the system as a whole.

History
This term was coined by the Celestial Ruminations System to describe a role that was more descriptive of what they felt a defender would be without being a protescutor as they did not feel it was an accurate description of the headmate it was conceived for.
