Gotham City is visited by a religious group called the Hellerites, a group of people who centuries ago owned the land that later became known as Gotham City; The forefathers of Gotham had forced the Hellerties off the land, and now they have returned with their apparent messiah and founder Josiah Heller was prophesied to come back and threaten to turn Gotham City into a desert unless the land was turned over to his people.
