Arioch is a Duke of Hell in the service of Dispater.
Arioch appears as a purple-skinned humanoid with diabolic features, except his head which resembles a lion-maned crocodile and his skin lightens to wine red from the shoulders up.
Arioch is a vassal of Dispater, serving as Dispater's avenger. Dispater often sends Titivilus to bring orders to Arioch; Titivilus treats Arioch as his peer, and Arioch shows no fear of Titivilus.
