Benjamin Villein, the Face-Tailor

His true name is Benjamin Villein, and he figured out the snuffer's skill at copying faces and turning them into masks. Understandably, the snuffers are a bit upset with him, and have persuaded the special constables to hunt him down. It is unknown whether or not he actually did something to deserve this. Before all this, he was employed at the ministry of public decency.

He recorded many hints and tips towards what he does in the Liber Visionis, or the Book of Faces.

During the fate locked story "A trade in faces" he is hiding from the law.
