Cornifer

Cornifer is first encountered in the bottom of The Forgotten Crossroads where he sells maps and advises The Knight to visit his wife Iselda's shop up in Dirtmouth, unlocking said shop when first encountered.

Cornifer can be found in every zone he sells a map for. Scattered papers on the ground lead to his location and his hum can be heard from a few rooms across.

Once the player has bought all of his maps or defeated all three Dreamers, he will be found in the map shop, sleeping in a loft bed.

Trivia

 * Cornifer can be found in two different locations within Deepnest, depending on which entrance the player has entered from.
 * He has a unique greeting dialogue if the player talks to him in Deepnest for the first time.
 * The only location where he does not hum is in the Deepnest, where he is visibly afraid for his life and doesn't want to give his location away to the beasts.
 * He will leave after the player has defeated the area's Boss, or has defeated all three Dreamers, and will leave a letter for the player stating that his map can be purchased from Iselda in Dirtmouth:
 * "Sorry I missed you! If you're feeling lost, why not pop up to our store in Dirtmouth and purchase a map of this area? Available now for an excellent price! - Cornifer"
