The park opend as an innocent amusement park with all the stuff you have in a normal one and other amusements. All of the fun rides were driven with ancient magic, but something evil happend (or came in) and the magic corrupted, people started to vanish and soon all the rides and attractions killed the visitors. After that a lot of exorcisms were carried out and purifying magic was used, but it never opend up again. The area was sold but nobody wants to buy it now. Today it is a "black hole" for magic, spirits and ghosts. There is nothing in there and nobody wants to go.
Max Maxwell hid there on the run from the Loas, but John found him and then the Loas.
