Sherma

"An optimistic pilgrim on a spiritual journey. Sherma’s path may often cross with Hornet’s own, but his lack of combat and acrobatic prowess can land him in desperate need of aid."

- Official description

Sherma is an NPC first revealed in the Hollow Knight: Silksong announcement trailer. He is a pilgrim on a spiritual journey who requires help from Hornet in certain situations.

Silksong
Sherma makes two appearances in the announcement trailer. He is first encountered in the "New Friends" tab, standing within what appears to be a hot cavern hallway alongside Hornet. He clangs the two objects he carries together whilst laughing, seemingly causing a large gate in front of the two to open.

He later appears briefly during the "New Towns" tab, resting next to a large structure admist what appears to be the entrance to a large city, with many large structures visible in the background.

A later blog post directly mentioned him, describing him as "a pilgrim on a spiritual journey", with a "lack of combat and acrobatic prowess" which can land him in trouble.
