Satan the Accursed
Satan the Accursed, self-described "man of wealth and taste," is the narrator of the play. (While he is an unreliable narrator, the alternative is prohibitively inconvenient to attempt to stage.)
Satan the Accursed is a firm believer in total human depravity, and has held this opinion since humanity first came into existence. (On occasion, Satan the Accursed will state that the actions of somebody, not necessarily a character in the play, have been added to the list of case studies that he is accumulating to prove his point. As the play begins, he has accumulated six trillion and three.)
As a being predating humanity, Satan the Accursed is capable of easily stepping sideways into the Absence, and perceives Presence and Absence equally well. He occasionally stops one conversation to engage in another with an Absent being; since other characters are unable to perceive the Absent under most circumstances, the rest of the cast assumes Satan to be unfathomably alien and possibly insane, a misconception he makes no effort to correct.
Despite his open hostility towards humans, Satan the Accursed is nonetheless quite willing to provide assistance to anybody who asks politely. In all cases, this assistance is taken as further proof of the irredeemably flawed nature of humans....
