Jack Prometeria

Jack Prometeria (ジャック＝プロメテリア) is a British magician who manages a shared ceremonial ground hidden in a container yard in 's harbor district.

Appearance
Jack Prometeria is described as a gray-haired old man, short but with thick muscles.

Background
Jack Prometeria's father was a magician who was on the crew of the battlecruiser, one of the few survivors when the ship was sunk in the icy waters of the north Atlantic, and frequently told the young Jack stories about the ship he proudly served on.

Jack eventually ended up in Calais, where he managed a hidden side to the container yard while officially working for the harbor. Taking advantage of the market created by problems faced by individual magicians due to the influence of powerful magic cabals, he rented out at least one shipping container as a shared ceremonial ground for magicians to use in exchange for physical cash. The container was moved around the yard at irregular intervals to make it harder to track down. Jack did not keep full records of the individual ceremonies his customers were performing, but he kept enough for him to track them down should they try to skip out on payments.

At some point, Jack learned that symbols of Aleister Crowley had somehow been worked into the ship and given Crowley's bad reputation among the magic side, Jack could not leave it like that, seeking to remove his influence from ship. Two years before the current year, he was told that he had about half a year left to live, but sought to purify and experience Hood himself before he died. To accomplish this, he devised and set up a complicated summoning ceremony, which would be inadvertently carried out by the magicians using the shared ceremonial ground.

Abilities
Jack has mentioned having methods to track down clients, even if they use a false name and address, should they try to skip out on payments. Only taking payments in hard cash, with a physical hand-over, he is apparently capable of using the residual information from the notes for tracing purposes.
