The location of the Giant Prison Cage was in London, only a few hundred meters from St. Paul's Cathedral, right next to the Demon Hunter Headquarters. If a Supernatural Being attempted to escape from prison, the Demon Hunters would respond immediately, recapturing them.
"They are all property of the Church!" Archbishop Brandon said loudly, "There are always some collectors who like exotic things and are willing to spend a fortune to buy live Supernatural Beings to display in their homes. This is one of the ways the Church profits. In the future, we plan to breed and domesticate these Supernatural Beings, in the hopes of making their temperaments less volatile and training them to become pets for the upper class!"
