He is a cartographer by trade who is working on mapping Hallownest. Would you like to buy a copy of his work so far? This character from our fanart Hollow Knight Cornifer cursor pack is an NPC. When Cornifer was first hatched, he walked away immediately, leaving his siblings and his mother behind. He later moved to Dirtmouth with Iselda as soon as he could. He can't be met in the Resting Grounds and always leaves this letter in the Stag Station of the Resting Grounds instead. Cornifer also never leaves a note in Deepnest.
