A physical manifestation of greed, Jackson is a surprisingly charismatic individual. He uses honeyed words and subtle inflections to garner information, and favor with the general populace. Often traveling great distances before taking up a new residence. He enjoys making deals with the "lesser" beings of the world, sometimes to gain a favor or something of value, other times to just enjoy the spectacle of someone getting what they thought they wanted. In either case the deals will always benefit him in someway, and do not always remain beneficial to the "client". Of course the binding agreements have no room for discussion, but he is a demon of his word, and will follow an agreement to the letter. But wording is key, and Jackson has had many years to practice his craft.

So yeah this is Jackson T. Ripps my proverbial Monkey's Paw character. The symbol on the page is his official seal, when an agreement is made it is placed upon the "client" depending on how the deal was made. Verbal deal it appears upon the tongue, sealed with a handshake it manifests on the palm of the hand, etc.
