The occult origins of Gotham are further delved into by Peter Milligan's 1990 story arc "Dark Knight, Dark City", which reveals that some of the American Founding Fathers are involved in summoning a bat-demon which becomes trapped beneath old "Gotham Town", its dark influence spreading as Gotham City evolves. A similar trend is followed in 2005's "Shadowpact" #5 by Bill Willingham, which expands upon Gotham's occult heritage by revealing a being who has slept for 40,000 years beneath the land upon which Gotham City was built. Strega, the being's servant, says that the "dark and often cursed character" of the city was influenced by the being who now uses the name "Doctor Gotham."
