Church Keeper

The Church Keeper is a character in Hollow Knight: Silksong. They appear to be carrying a large woodwind instrument.

Silksong
Hornet meets the Church Keep just as she makes it out of the Moss Grotto from the Old Church and collapses. They act as a mentor of sorts throughout her journey in Pharloom. In the trailer they are seen singing while Hornet plays her Needle.
