Esonogos

Esonogos is a mysterious character, encountered only by jumping into the portal created by the Witch she creates when angered by the player when questioned about Nkaanmykiunsuns's accusation of a murder committed by her, after informing her of an attempt on her life.

The creature doesn't initially react to the player or their attempts at a conversation. When the Witch appears shortly after, angry at the player, she quickly falters and pleads to Esonogos, saying that the player is just a 'by-product' and begs to not have to kill them. The creature then tells her to "Just get rid of it." Following this, the player is tossed back through the portal and out of the Witch's burning house.

The name itself isn't mentioned in the game itself, rather it's how the creature is referenced in the game files.
