The human that foiled the revolution that was supposed to take place against the Rephaim in Sheol I. It was revealed at the end of The Mime Order that this human was Jaxon Hall, I-4's mime lord and Paige's employer/mentor. As a result of this betrayal, Warden and the other Rephaim who were involved in helping the humans revolt were tortured and are now referred to as The Scarred Ones. All the other humans were killed, including, it is rumoured, a child (XVIII-39-0); but this child's body was never found.
