Located deep within the forest not far from the mansion, this ritual site is where Viktor would offer Kate's O'Zhuvindo (life force) to his late wife Mary in order to resurrect her. The ritual site consists of an altar with an enormous female statue and four towers, each powered with encased hearts.
Detective Roland Childs deduced that the four towers draw psychic energy from the square. The hearts encased in the machine of each tower will convert the energy into another substance and feeds it to the altar in the rear.
