The Ceremony must be performed or evil will rule the Earth.
An angel was cast out of heaven and dispatched to Earth 1400 years ago. The angel was made a slave of the devil and was sent forth to terrorize mankind. To rid the world of this evil threat a "device" was erected to imprison the angel. Now the "device" is about to open. The Ceremony must be performed to keep the angel imprisoned or evil will rule the Earth.
