Church Keeper

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

Hornet meets Church Keeper 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.

In the Moss Grotto demo, they witness Hornet falling unconscious on the ground and start laughing, right before the end of the demo.
