Sariel

The Chief of the Principalities - in charge of the "Mid-Air Corridor" (which is between the 4th and 5th levels of Heaven and is where fallen angels are imprisoned). He was killed by Zaphikel when Zaphikel, despite going insane and becoming a ghoul, manages to regain control of himself and pierces Sariel's eye. (He is immune to the powers of Sariel's eye due to his blindness.) He has an Evil Eye, who can kill beings of lesser will outright, or control the bodies of others.
