The Silent Protagonist of the game, Serph is the leader of the Embryon. Even with his emotions awakened, he remains a calm and composed leader for his Tribe. Over the course of the game, he forms a bond with Sera and soon becomes determined to protect her. His Atma is the Water Crown, and his demon form is Varna. He is based on Sera's perception of who Serph Sheffield was. His lack of personality reflects how little she actually knew of the real Serph; however, he grows as a character and becomes distinct from both the original Serph Sheffield and Sera's false perception of him.
