Ring that belonged to an overseer of the Church of Wax.
 
When a congregant of the church wishes to confront their shadow, they must become the subject of a ritual. It is a perilous undertaking and can result in the explosive corruption of the subject.
 
If another congregant feels inclined to intervene, they may place an empty husk over the subject's finger, tranforming it into this ring and thereby abstaining the corruption.
 
The fate of the wearer, however, is inexorable. Eventually, all men become beasts.
