Paimon

Paimon is a demon discussed in the Ars Goetia section of the Lesser Key of Solomon. Paimon is listed as being a King of Hell and is said to have one to two hundred legions of demons under his command. The precise number varies from author to author. He is also said to be the most loyal to Lucifer of all the kings.

Once summoned, Paimon can teach the conjurer all kinds of things, from philosophy and science to the mysteries of the Earth. He will reveal to the conjurer anything he wishes to know and can give to them good familiars. He is also capable of making others subservient to your will.

Paimon is descirbed as a strong man with facial features more closely resembling those of a woman. He wears a crown and travels on the back of a dromedary camel. He is usually proceeded by a host of demons that appear as a sort of grotesque marching band to herald his coming.
