According to Johan Weyer, Abigor is the Grand Duke of Hades. He is shown in the form of a handsome knight bearing a lance, standard, or scepter. He is a demon of the superior order and responds readily to questions concerning war. He can foretell the future and instructs leaders on how to make themselves respected by their soldiers. Sixty infernal regions are under his command.
