The Goetia calls Purson a great king of Hell, but with only twenty-two legions, he doesn’t sound like much of a king. For example, Sallos is a duke and he has thirty legions.
When he shows up, he has a ton of trumpets heralding his arrival.
He knows where all hidden things here, and can discover treasure. He knows and will tell everything past, present, and future, secret and divine, even back to the creation of the world.
