Mayor Sidel
First mentioned in: 103: Usual Suspects
The mayor of Arkham. He is never seen or heard directly; everything known about him comes from what other characters say.
In 103: Usual Suspects Detective Frank Kovach says that Corbitt could not be the Miskatonic Mangler, because on the night of the latest murder Corbitt was at a business dinner with the mayor himself.
In 201: Wrong Place at the Wrong Time a radio report on the aftermath of the Corbitt case says that the mayor is distancing himself from his former friend.
In 311: Beefing the Defenses Dr. Simeon uses a command spell to force Mayor Jedediah Marsh of New Jerusalem to name the man who paid him to watch Corbitt and Mordecai Shep. Marsh answers "Mayor Sidel of Arkham", and the players connect the name to Corbitt's dinner alibi from season one.
In 401: Static Prevails the Keeper recalls that Mayor Marsh's last words to the group were "Mayor Sidel of Arkham," which have so far led only to more questions. Nothing else is said about him.
In 403: I Will Steal You Back Major Bakersfield wonders whether the mayor might be connected to the "RG" on the pawn shop watch and suggests finding out who works closely with the mayor, but the others prefer to follow the watchmaker.
In 407: Coffee & Cigarettes a player asks the barista Sheamus O'Malley whether the O'Malleys ever loaned anyone to the mayor, calling him Mayor Seidel of Arkham, and whether he has heard of the mayor being involved in anything untoward. Sheamus says that there are always rumors about the important people in town but that he has never given any of them credence.
