Charoel
Charoel: An infernal duke attended by four hundred ministering spirits. Charoel appears in the hierarchy of the demon Macariel, described as a wandering prince in the Ars Theurgia. Charoel and his compatriots are free to appear in any hour of the day or night. He has command over diverse forms but often prefers to appear as a many-headed dragon. He also appears as one of twelve chief dukes said to serve the demon Soleviel, another wandering prince of the air. This version of Charoel only serves his demonic master every other year. One thousand eight hundred and forty ministering spirits exist to carry out his commands.
