An Ex-Player named Archie, presumably the Players father.
Journal Missing-Page #16 lead us to believe he was responsible for the Glowvirus Apocalypse during his time in the game under the impression it was for the good of Paraphore.
He sacrifices himself by having Mary push him into the Engine Fluid to test the infection. At some point, Som had raped him and Mynt had disabled his actions.
As of the Apocalypse ending, he is in Glowvirus form hiding with Roxelle Devaunt from the Apothecary.
