Bidos was the chief leader of the group of mostly biomancers who called themselves the Zoarchs. He now serves as an avatar of Tehsh. He is forced to be the angel of death to the innocent for all eternity. This was his punishment agreed upon by the God King and the Aygeemya for all the suffering he brought into the world. Bidos is used as a cautionary tale to young remnant as a sort of bogyman. He is noted as having tears etched into the sides of his face as a symbol of his grief for his actions.
