In Hell, Amon is a Marquis, commanding forty legions of lesser demons.
When summoned, Amon can help you create feuds between your enemies, and can also reconcile people who have been fighting.
He shows up looking like a wolf with the tail of a snake. But you can also ask him to shift into the guise of a man with the head of a raven, if that’s what turns your crank. Or he can have a raven’s head with canine teeth. Your call.
He can also breathe fire.
This demon can give you secret insights into the past. He can also foresee the future (Though I can foresee your future, too, if you actually try to summon demons. Short life and long regrets).
