Is there a phobia that leaves the individual afraid of people knowing their identity? I'm thinking there could have been a Consul (essentially a Saint) in the Church of the Suffering Grace who suffered from such a phobia so intensely, they covered themselves head to toe in garments to hide from people knowing who they are.
Consuls of the Church are constituted from those who put themselves through anguish seemingly by instinct, for to do so demonstrates an innate, yearning desire to repay the Restitution of Knowing. As such, the fear this person suffers from would be reinterpreted as a form of great penance by the Church. They would die without anyone knowing who they truly were.
The closest phobia I can find that relates to this of scopophobia, the fear of being looked at. The thing that separates this individual from that, however, is their desire to block out *every* aspect of themselves. Name, sex, voice, etc.
