In Christian demonology (Late Medieval- Early Modern European), Chomiel is a Chief Duke (correct, not a Grand Marquis), one of 12 working for Demoriel, Emperor of the North, one of the angels of the compass directions. He is found referenced in the Ars Theurgia Goetia (the second book of the Lesser Key of Solomon). The other emperors are: Carnesiel (East), Caspiel (South), and Amenadiel (West). These angels and their servants are considered to be able to perform both good and evil.
