25 years ago the gate to the under world was opened and then the forces of darkness(demons) surfaced to the world
The world was in chaos and then the main evil arose ,it was the devil (the fallen queen) her appearance was like that of an angel but inside was uglier and deadlier than a beast
Then the heavens opened and the forces of God came down on earth and there was destructuction everywhere then God and the devil(the fallen queen)clashed and after the clash there was a bright light in the sky then the light dimmed and there was no good no evil.
The forces of darkness retreated,tho the battle was won but a lot was lost
The gate to the underworld remained opened
It can't be sealed by any existence Because only God had that type of power
