Mammon is one of the seven Satans, the Satan of Avarice. His form is two-headed and vaguely bird-like.

Mammon – In the Bible, Mammon is not a demon, but rather an Aramaic word meaning “wealth” or “property”. Matthew 6:24 says, “No one can serve two masters. He will either hate one and love the other, or be devoted to one and despise the other. You cannot serve God and mammon.” In “Paradise Lost”, Milton calls Mammon the demon of avarice who, even before his Fall, was more concerned with riches than with what was divine. In hell, he decorated the palace of demons, Pandemonium, in gold and jewels. It is also said that Mammon taught humans the art of mining for precious gems and metals.
